Abstract:
Rich mineral paper (RMP) has the advantage of being energy efficient, clean and creating no pollution during its production processes, with low production costs, and enjoying naturally complete biodegradability, fully compatible with the emerging demands for energy efficient carbon reducing features and the trend for environmentally green solutions, so if this media can replace traditional paper uses to become a new print media, tremendous environmental efficacy can be expected. So this study aims to discuss the print quality performance characteristics of RMP applications in large print run offset printing operations. The study deploys True Experimental Study methodology, with use of the digital printing test target of Graphic Arts Technical Foundation (GATF), with flat offset printing on traditional coated paper and eco-friendly RMP, printing 800 sheets of each, with systematic random sampling of 35 samples for the study. Quality determinations rely on X-rite i1 Pro for elucidation of the printing quality characteristics for solid ink density, TVI, contrast, gray balance, and color gamut measurement. The results of this study indicate the KCMY solid ink density and contrast of the eco-friendly RMP were less than traditional coated paper; TVI value was higher than traditional coated paper; color gamut performance was less than the traditional coated paper. Optimal gray balance combination for RMP was determined as follows: 7% tone with C7M3Y4, 30% tone with C30M28Y26, 60% tone with C60M58Y5, and 80% tone with C80M76Y66. The study suggests that ink particularly suitable for RMP uses remains in need of development. Additionally, the study found that use of RMP in the paper machinery indicated transverse and longitudinal tensile strength is slightly inferior to the traditional coated paper, resulting in unsmooth surfaces post-printing, for which it is recommended that RMP makers should consider paper machinery structural aspects when pursuing future research on modifying solutions for greater printing efficacy with RMP.

AbstractThis paper discusses the development of environmentally-friendly precursor inks suited for ink-jet printing of functional ceramic coatings. We synthesized superconducting materials, SrTiO3 thin films for coated conductor applications and transparent TiO2 photocatalytic coatings. Here, we discuss all aspects of ink formulation, including the stabilization of metal ions, nanoparticle inks or combination of both. This demands the investigation and determination of the inks rheological parameters. Ceramic nanoparticles are often incorporated in our inks to decrease thermal processing temperatures (e.g., TiO2 or YSZ coatings...) or enhance the properties of the functional ceramic coating (e.g., pinning centres in superconducting coatings). These ceramic nanoparticles (ZrO2, HfO2, TiO2...) are synthesized through methods based on microwave heating from aqueous and/or organic solutions. With that, we aim at developing smart and environmentally friendly processes that require lower energy input.

Abstract:
Purpose The purpose of this paper is to study the repeatability of path manufacturing in the drop on demand inkjet printing process and the influences of environmental and application factors on path resistance. Design/methodology/approach Paths were printed as multiline paths in packets one-, two- and three-layer paths on polyimide substrates using nanoparticle silver ink. The sintering conditions were determined experimentally. The paths were subjected to climatic and shock exposures and to bending processes. The resistance, profile and width of the paths were measured and analyzed. The temperature distribution for electrically heated paths was measured to identify the defects. Findings This research shows the repeatability of printing processes and identifies the sources that cause diversification in path parameters after the whole technological process. The influence of shock, climatic and mechanical exposures on path electrical properties is indicated. An effective method for identifying defects thermally is shown. Research limitations/implications The research could have limited universality by arbitrarily use of substrate material, ink, printhead, process parameters and kind of sample exposures. Practical implications The research includes practically useful information about the width, thickness, defects and resistances and their changes during a typical application for a path printed with different technological parameters. Originality/value This research presents the results of original empirical research on problems concerning the manufacture of paths with uniform parameters and shows how path parameters will change under exposures that may occur in a typical application. The research combines both production and application aspects.

Abstract:
Purpose The purpose of this study is to explain the effects of screen printing parameters on the quantity of ink deposited and the print quality in the context of printing of functional inks. Both these aspects of printing are crucial in the case of conventional and functional printing. This is because, in the case of conventional printing, the quantity of ink deposit affects the color strength while in the case of functional printing, it directly affects the resulting functionality of the ink layer. Design/methodology/approach In this work, an automatic lab-scale screen printer was used to print functional inks on a paper board substrate. The printing parameters, i.e. printing pressure and squeegee angle were altered and the resulting effects on the quantity of ink that was deposited were recorded. The quantity of ink deposit was related to its surface resistivity. In addition, the quality of the print was also assessed by examining the design registration quality. Findings The authors found that altering the squeegee angle has a significant effect on the properties of the resulting ink deposit. More importantly, the authors found that the deflection in the rubber blade squeegee was greatly dependent on the initial angle of the squeegee at the start of the printing stroke. For each set value of the squeegee angle that was considered, the actual angle during printing was recorded and used in the analysis. A printing pressure of three bars and squeegee angle of 20° resulted in the maximum weight of ink deposit with a correspondingly lowest surface resistivity. Practical implications This study is envisaged to have considerable practical implications in the rapidly growing field of functional printing of flexible substrates including, but not limited to, textiles. This is because, the study provides an insight into the effects of printing parameters on the characteristics of a functional ink deposit. Originality/value Screen printing of flexible substrates is a well-developed and arguably the most widely used printing technique, particularly for textiles. Numerous studies report on the analysis of various aspects of screen printing. However, to the best of the knowledge, the effects of printing parameters on the characteristics of functional inks, such as electrically conductive inks, have not been studied in this manner.

Abstract:
In the Printing Industry, printing inks, varnishes, lacquers, moistening solutions and washing solvents (ethanol, methyl acetate, ethyl acetate, isopropanol, n-propanol, hexane, benzene, toluene, xylene, isopropyl acetate, propyl acetate, dimethyl ketone, glycols and glycol ethers) contain volatile organic compounds (VOCs) and air pollutants (HAPs). Especially solvent based inks used for flexo, gravure and screen printing, offset printing dampening solutions and cleaning solvents contain high concentration of VOC. These organic compounds evaporate during the production process or contribute to the photochemical reaction. VOCs and HAPs, together with sunlight and nitrogen oxides, cause photochemical smoke, air particles and ground level ozone emission in the atmosphere. The VOCs and heavy metals can lead to soil and even water pollution when left in landfill. The amount of solvent retained by flexo, gravure and screen-printed products is 3-4% of total ink solvent used. The solvent in the printed ink content, except for the one held by the printed material evaporates in its own environment after the printing process. Most of these solvents and organic compounds used in printing environment contain at least one carbon and hydrogen atom and have negative effects on health and environment.In this study, the environmental impacts and risks of inks and solvents used in the printing industry have been evaluated. Measures to be taken to reduce and manage these environmental effects and risks have been addressed and recommendations have been made.

Abstract:
People pay more and more attention to water-based printing inkjet ink which has no environmental pollution and fits environmental protection requirements. Inkjet printing technology could be applicable small batch and various variety products and satisfy the customer’s personalized requirements. Resin as one of the main compositions of printing inkjet ink has important effects on ink’s performance. To determine the effects of resin on the performance of water-based printing inkjet ink, adopting grinding method prepare the samples by changing resin and its proportion. By testing the samples’ particle size, viscosity, surface tension, pH value, the effects of resin on the water-based printing inkjet ink were analyzed. The results show that the type of resin and composite ratio has some effects on the performance of printing inkjet ink. When the resin was mixed in accordance with Resin B/Resin C=29/21, the performance of printing inkjet ink which was diluted with this resin was better.

Abstract:
Printing ink wastewater is usually very difficult to treat biologically and its chemical oxygen demand (COD) far exceeds standards of discharge. The COD in wastewater is usually 3,000 to 8,000 mg/L after flocculation and sedimentation. Herein, a strain of bacterium was isolated from the sludge and identified as Bacillus sp. and utilized to treat printing ink wastewater. The application of bacteria to degrade printing ink in wastewater is discussed in this paper. The influence of N and P sources on COD removal, and COD removal in combination with glucose was also discussed. More than 85 per cent of the COD could be removed using the proposed biological process. A novel internal airlift loop bioreactor with bacteria immobilized onto ceramic honeycomb support was used for the wastewater treatment.

Abstract:
The era of environmental protection and personalization has become increasingly prominent, and people not only focus on the beauty of the design, but also pay more attention to the quality of the clothing. For inkjet printing, the viscosity and surface tension of ink are major factors that affect the quality of ink-jet printing. In order to obtain a better print quality, the samples of five different viscosity and surface tension of ink were prepared respectively by changing the content of the resin and the surface active agent. Using these samples to print on the fabric by Epson printer, and to discuss the influence of the ink in different viscosity and surface tension on the ink-jet printing quality, such as apparent color depth (K / S), color parameters (L, C), permeability, clarity. The results showed that: with the increase of the ink viscosity, the apparent depth of color yield increased gradually and became darker in color. L value decreased gradually and had a increasing trend, and tends to be stable. C value increased and vividness of the color was improved. And it also had a certain impact on the infiltration resistance and clarity. Surface tension also had a significant impact on the depth of the apparent color, vividness of the color and directly affected the ink permeability and clarity.

Abstract:
Ink transfer and setting influence the achievable print quality and visual appearance. The pressure in the printing nip and the porosity of the substrate regulate the amount of ink that penetrates into a porous coating structure. The purpose of this study was to understand how print quality aspects could be related to ink penetration of water-based flexographic ink into coatings of differently engineered structures: calcium carbonate (GCC) of various particle size distribution (PSD), coatings with different amounts of latex binder, and coatings with various blends of GCC and kaolin. Calcium carbonate with broad pigment PSD resulted in a lower print density compared to coatings of narrowly distributed particle sizes. Coatings of larger pore volume and greater dominating pore radius showed a higher amount of z-directional ink penetration. A high ratio of uncovered areas (UCA) could be detected for samples with high amount of latex. However, increased printing force eliminated these artefacts. Increased printing force increased the print density to a higher degree than did a reduced ink viscosity for coatings with pure GCC. For coating layers containing both GCC and kaolin clay, decreased ink viscosity had a stronger impact on the print density than increased printing force. Print density was also affected by ink penetration, suggesting that the optical response is sensitive to the ink-substrate interaction layer. The result presented in this work also suggests that the print gloss decreases with increased amount of penetrated ink due to a higher rate of ink vehicle removal.

Abstract:

In this work, different aspects on the re-use of wood based fibres have been studied, focusing on ink detachment of flexographic ink from model cellulose surfaces and changes in porous structure of kraft fibres following different treatments. New model systems for evaluation of ink detachment and ink-cellulose interactions were used. Ink detachment was studied using Impinging jet cell equipment, taking into consideration the influence of storage conditions, surface roughness and surface energy of the cellulose substrate. A micro adhesion measurement apparatus (MAMA) was used to directly study ink-cellulose interactions, from which the adhesive properties between ink and cellulose, having various surface energies, could be derived. UV-light, elevated temperatures, longer storage time, decreased surface energy, i.e. making the cellulose surface more hydrophobic, and high surface roughness all negatively affected ink detachment. Attenuated total reflectance - fourier transform infra red (ATR-FTIR) and atomic force microscopy (AFM) was used to evaluate structural and chemical changes of ink and cellulose upon storage at elevated temperature or under UV-light. After storage at elevated temperatures, ATR-FTIR spectra indicated that a hydrolysis or an oxidative reaction took place as a peak at 1710 cm-1 appeared. AFM revealed that storage at elevated temperatures caused the latex particles present in the ink to form a film, most likely due to annealing. Less ink detached from hydrophobic cellulose surfaces. Ink detachment decreased for rougher cellulose substrates due to an increased molecular contact area.

Fibre pore structure and water retaining ability influenced fibre/fibre joint strength and different paper strength properties. Investigations took into account the effect of pulp yield, counter-ion types, pH, salt, hornification and strength enhancing additives. Nuclear magnetic resonance relaxation (NMR), inverse size exclusion chromatography (ISEC) and water retention value (WRV) measured the changes that occur in the fibre wall upon varying the conditions. Each different measuring technique contained unique information such that a combination of the techniques was necessary to give as complete a picture as possible over the changes that occurred in the fibre wall upon varying the conditions for the fibre. A correlation between fibre pore radius and sheet strength properties was found, suggesting that fibres with larger pores allow for a larger molecular contact area between fibres to be formed during drying and consolidation of the paper. Fibre/fibre joint strength, fibre flexibility, and the number of efficient fibre/fibre contacts also controlled sheet strength. The effect of different strength enhancing additives on fibre pore structure and paper strength was investigated. Larger pores in the fibres allowed for additives to penetrate into the fibre wall. Additives with low molecular mass (Mw) penetrated into the fibre wall to a larger extent than additives with a high Mw, causing an embrittlement of the fibre. However, low Mw additives gave higher sheet tensile strength despite a leveling out in strength at high additions, indicating that the fibre wall can only adsorb a limited amount of chemical. Polyallylamine hydrochloride (PAH) and polyelectrolyte complexes (PEC) of PAH and polyacrylic acid (PAA) were added separately to the pulp. PEC significantly improved both tensile strength and Z-strength, whereas PAH alone did not increase the strength properties to the same extent unless the sheets were heated to 150°C for 10 minutes. The results suggested that the effect of PEC was dominated by an improvement in fibre/fibre joint strength, whereas the effect of PAH was significantly affected by an improvement of the intra-fibre bond strength

Abstract:
This experimental study compares green printing technologies (ink and stock) to traditional printing technologies (ink and stock) regarding how they compare in quality. The quality was measured using the print characteristics of gray balance and dot gain. A comparison of the two independent variables (ink and stock) was conducted to determine if a difference exists for the selected characteristics. It has been suggested that the green technologies, despite being more environmentally friendly, are not as high in quality and therefore result in a lower quality printed piece. This research used a four-color test form that was printed using both the green and traditional technologies. The characteristics were measured using an X-rite 528 spectrodensitometer, after which the data were analyzed and conclusions reported. The results of the study suggest that there is no practical significance between the different inks and stocks employed in this study. It was determined however that the best print quality in terms of dot gain (meaning the least amount of dot gain) resulted from the combination of green technologies (ink and paper).

Abstract:
Textile industries are one of the prevalent water consumers and contaminators ensuing high generation of waste water. Wastewater from dyeing and printing units is often rich in organic compounds, colours, and heavy metals containing residues of various dyes and chemicals. Among these waste water pollutants, heavy metals are of serious environmental concern in recent years. Metals are extensively used for manufacture of synthetic dyestuffs and for colouration of natural dyes on textiles to achieve different shades and hues. Heavy metals such as lead (Pb), chromium (Cr), cadmium (Cd), iron (Fe), zinc (Zn), copper (Cu), etc. are widely used for production of colour pigments of textile dyes. These heavy metals, highly toxic, get conveyed to the environment, and can bio-accumulate in the human body, aquatic life, natural water-bodies, and also possibly become trapped in the soil. The chapter deals with the utilization of heavy metals in textile wet processing, their important characteristics, various toxic aspects, and different methods for their elimination from the textile effluent liquors.

Abstract:
Recently, all industrial sectors have shown significantly increasing attention in reaching the sustainability goals regarding economic, environmental, social, and also technological aspects not only at the regional level but also nationwide and even global scale. Aside from being an economically popular concept, sustainability is strictly related to effective resource use and efficient waste disposal. Thus, it functions as a complementary issue to be considered in various production activities. The sustainable production approach includes reducing or (if possible) eliminating the negative impacts on the human health and environment, reducing the waste generated, increasing the recycling rate, and developing energy and material saving processes. The printing industry is one of the most important industries in reaching sustainable production goals. The need for the printed products, which is the focus of this study, is increasing in parallel with the changing consumer expectations and technological developments. However, from the point of the printing industry view, a solid sustainability consensus is not settled among the practitioners, yet. This study aims to evaluate the sustainability of the cardboard label production considering several combinations of raw materials such as paper, ink, and surface coating additives via appropriate Multi-Criteria Decision Analysis (MCDA) methods. The most frequently used paper and ink types are considered with three alternatives for each. To indicate the sustainability scores economic, environmental, and social evaluation criteria are selected. By applying the Multi-Attribute Utility Theory (MAUT), the sustainability score of each label is calculated to determine the optimum alternative in terms of the production process and also the material used. This evaluation provides detailed information to the producer and also to the consumer about the alternative production routes to use less energy and raw material, and also to decrease the environmental impacts while sustaining the economic feasibility. Besides, alternative solutions are offered to reach sustainability goals by considering the economic and environmental life cycle impacts of these materials. Hence, an increase in awareness about the printing industry and service channels is expected. Moreover, this study is also important in presenting the applicability of sustainability assessments in the printing industry.

Flexible electronics and 3D printing are quickly reshaping the world in many aspects spanning from science, technology to industry and social society. However, there still exist many barriers to impede further progress of the areas. One of the biggest bottlenecks lies in the strong shortage of appropriate functional inks. Among the many printable materials ever tried such as conductive polymers, powdered plastic, metal particles or other adhesive materials, the liquid metal or its alloy is quickly emerging as a powerful electronic ink with diverse capabilities from which direct printing of flexible electronics and room temperature 3D printing for manufacturing metal structures are enabled. All these fabrication capabilities are attributed to the unique properties of such metal’s low melting point (generally less than 100 °C), flowable feature and high electrical conductivity etc. To better push forward the research and application of the liquid metal printed electronics and 3D manufacture, this article is dedicated to present an overview on the fundamental research advancements in processing and developing the liquid metal inks. Particularly, the flow, thermal, phase change and electrical properties of a group of typical liquid metals and their alloy inks will be systematically summarized and comparatively evaluated. Some of the practical applications of these materials in a wide variety of flexible electronics fabrication, 3D printing and medical sensors etc. will be briefly illustrated. Further, we also explained the basic categories of the liquid metal material genome towards discovering new functional alloy ink materials as initiated in the authors’ lab and interpret the important scientific and technical challenges lying behind. Perspective and future potentials of the liquid metal inks in more areas were also suggested.

Abstract:
Abstract The goal of this work is to forward a comprehensive framework, relating to the most recent research works carried out in the area of flexible and hybrid electronics (FHE) fabrication with the aid of aerosol jet printing (AJP) additive manufacturing process. In pursuit of this goal, the objective is to review and classify a wide range of articles, published recently, concerning various aspects of AJP-based device fabrication, such as material synthesis, process monitoring, and control. AJP has recently emerged as the technique of choice for integration as well as fabrication of a broad spectrum of electronic components and devices, e.g., interconnects, sensors, transistors, optical waveguides, quantum dot arrays, photodetectors, and circuits. This is preeminently because of advantages engendered by AJP process. AJP not only allows for high-resolution deposition of microstructures, but also accommodates a wide renege of ink viscosity. However, AJP is intrinsically complex and prone to gradual drifts of the process output (stemming from ink chemistry and formulation). Consequently, a large number of research works in the literature has focused on in situ process characterization, real-time monitoring, and closed-loop control with the aim to make AJP a rapid, reliable, and robust additive manufacturing method for the manufacture of flexible and hybrid electronic devices. It is expected that the market for flexible electronics will be worth over $50 billion by 2020 [1].

Abstract:
The long term goal of our work is to develop a fabrication technique that allows precision placement of cells inside biomaterial constructs. Such spatial and temporal control of the chemistry and pattern geometry can provide new insights into fundamental aspects of cell-surface interactions. For example, cellular development can be dramatically effected by constraining cells to spread over a specific cell-surface contact area. The cell and biomaterial printing techniques developed here may prove particularly useful for exploring the interactions of anchorage-dependent cells with their environment in vitro. Our recent studies addressed the simultaneous printing of endothelial cells and biomaterials. The studies further demonstrated that cells can be printed onto polymer scaffolds or fibers without significant loss of cell activity. A combination of these methods may result in the construction of vascularized tissue with mechanical properties approaching those of native tissue.

Abstract:
A novel method for the manufacturing of electric microconductors for semiconductor and other devices is presented. The method brings together three technologies: controlled (on demand) printing, laser curing, and the employment of nanoparticles of matter, possessing markedly different properties (here, melting point) than their bulk counterparts. A suspension of gold particles in toluene solvent is employed to print electrically conducting line patterns utilizing a modified on demand ink jet printing process. To this end, microdroplets of 80–100 μm diameters are deposited on a moving substrate such that the droplets form continuous lines. Focused laser irradiation is utilized in order to evaporate the solvent, melt the metal nanoparticles in the suspension, and sinter the suspended particles to form continuous, electrically conducting gold microlines on a substrate. The ultra fine particles in the suspension have a diameter size range of 2 – 5 nm. Due to curvature effects of such small particles, the melting point is markedly lower (400°C) than that of bulk gold (1063°C). Thermodynamic aspects of the effect of particle size on the melting and evaporation temperatures of gold and toluene, respectively, are discussed in the paper. The structure and line width of the cured line as a function of the laser irradiation power and stage velocity are reported in detail. Preliminary measurements of the electrical conductivity are represented.

Abstract:
Traditionally, the complexities and costs associated with design conceptualization (e.g., 3D scanning) and design realization (e.g., 3D printing) have limited the diversity of individuals capable of participating in the process to individuals/entities with advanced technical backgrounds or substantial financial resources. The authors of this work propose a methodology that utilizes low cost hardware and open source software to make the capture, reuse and management of design knowledge more accessible to the general public. 3D scanners are digital tools that facilitate the conversion of physical object information into the digital space through multiple image capture techniques. 3D scanners have the potential to revolutionize design conceptualization in society by enabling individuals to seamlessly transform physical representations of objects into a digital 3D rendered version. The 3D rendered version can then be manipulated using existing 3D CAD tools (e.g., SolidWorks) and subsequently printed using a 3D printer. Design realization via 3D printers (e.g., RepRaps) is becoming an integral aspect of the engineering design process. While the conceptualization of designs (e.g. CAD models) helps designers visually experience potential candidate designs, product prototypes that can actually be touched and manipulated add an important ‘feedback’ dimension to the engineering design process. This scan-edit-print approach to design conceptualization and realization will enable designers collaborating in online environments to work towards achieving a common design by providing them with tools and techniques. A case study is presented that demonstrates the feasibility of the scan (knowledge capture), edit (knowledge reuse) and print (knowledge management) approach to design using low cost hardware and open source software.

Abstract:
The promise of cheap and widely available 3D printers may be one of the best and worst aspects of Additive Manufacturing (AM). A non-technical consumer may pay significantly more for a 3D printer with “no assembly required”. Since it is reasonable to assume that they may not understand how the printer works and what will come out of it, they may wind up returning it because it does not meet their expectations. While consumers are starting to use 3D printers, designers in industry are utilizing Rapid Prototyping (RP) machines to manufacture final products in addition to prototypes. Designers will need to know AM principles in order to communicate design specifications to a RP lab technician so that a part passes Quality Assurance inspection. Training users on fundamental layer-based manufacturing methods can assist before and after a 3D printer purchase and reduce the strain on RP labs in industry. This paper presents an extensible software application that simulates an AM process in a Virtual Reality (VR) environment. The application parses machine component movements and printed segment attributes from G-code files exported from the MakerBot® Computer Aided Manufacturing (CAM) software. Position, speed, and type of movement are used to simulate the physical machine movements. A print “segment” is created at the start and end positions of a print movement. Color-coding segment attributes and modifying their size and shape establishes a visual relationship between terminology for a print setting and its representation in the virtual environment. This visual relationship between printed segments and print settings makes it easier to learn the 3D printing process and associated terminology. Novice and expert users can modify print settings in the virtual environment before and after printing a prototype. Identifying and fixing a mistake in the virtual environment reduces the time and cost to print a part with the desired quality. Training multidisciplinary users in a virtual world allows them to explore AM processes in detail from any angle or scale desired. This application has been tested in a cube shaped virtual reality CAVE system with each side measuring ten feet powered by a 96-node graphics computer cluster. Approximately 20 hours of demonstrations have been performed for public outreach programs related to STEM initiatives and visitors from industry who have had a variety of AM experience.

Abstract:
3-D culture has been shown to provide cells with a more physiologically authentic environment than traditional 2-D (planar) culture [1, 2]. 3-D cues allow cells to exhibit more realistic functions and behaviors, e.g., adhesion, spreading, migration, metabolic activity, and differentiation. Knowledge of changes in cell morphology, mechanics, and mobility in response to geometrical cues and topological stimuli is important for understanding normal and pathological cell development [3]. Microfabrication provides unique in vitro approaches to recapitulating in vivo conditions due to the ability to precisely control the cellular microenvironment [4, 5]. Microwell arrays have emerged as robust alternatives to traditional 2D cell culture substrates as they are relatively simple and compatible with existing laboratory techniques and instrumentation [6, 7]. In particular, microwells have been adopted as a biomimetic approach to modeling the unique micro-architecture of the epithelial lining of the gastrointestinal (GI) tract [8–10]. The inner (lumen-facing) surface of the intestine has a convoluted topography consisting of finger-like projections (villi) with deep well-like invaginations (crypts) between them. The dimensions of villi and crypts are on the order of hundreds of microns (100–700 μm in height and 50–250 μm in diameter) [11]. While microwells have proven important in the development of physiologically realistic in vitro models of human intestine, existing methods of ensuring their surface is suitable for cell culture are lacking. Sometimes it is desirable to selectively seed cells within microwells and confine or restrict them to the microwells in which they are seeded. Existing methods of patterning microwells for cell attachment either lack selectivity, meaning cells can adhere and migrate anywhere on the microwell array, i.e., inside microwells or outside of them, or necessitate sophisticated techniques such as micro-contact printing, which requires precise alignment and control to selectively pattern the bottoms of microwells for cell attachment [12, 13].
