Abstract:
Additive manufacturing has a great potential in terms of its capability to produce components with complex geometries and to make multi-material and composite products by combining different materials in a single manufacturing platform. Current trends for the multi-material extrusion additive manufacturing process are categorized by multi-nozzle systems and multi-material inlet systems. In the case of multiple nozzle system, materials are deposited from different nozzles in sequence. On the other hand, in the case of multi-material inlet system, different materials are sent into a mixing tube and deposited as a mixture of materials. In this case, functionally graded parts can be fabricated by changing the volume fraction of two or more materials. Hence, the fabrication of parts with a continuous material supply by varying ratios for the extrusion technologies requires the development of printing heads with suitable printing channels, capable of varying the mixing ratio of different materials. To evaluate the effect of different printing channel designs on the material’s flow pattern and the functionally graded material printability, this paper presents a three-dimensional transient computational fluid dynamics (CFD) simulation of the two miscible liquid-liquid system in a printing channel. Different geometries and materials are considered

Abstract:
The focus of this study was to test a low-cost level plastic printer in the multi-material printing application using principles of design for additive manufacturing (DFAM). Two sample structures were designed in the project. One of the main planning principles of the examples was to integrate multiple functions into one part and intelligently utilize a variety of materials and reduce parts count. The most common material used in the experiments was the basic PLA, which is widely used, easy-to-print and economical alternative. As special materials, electrically conductive PLA-based graphene filament and highly flexible polyurethane-based filament was used. The results show that multi-material printing is also possible with lower cost devices and it makes it easier for smart products to be manufactured cost-effectively. It has also been found that multi-material printing can be technically challenging and that further research and experiments in this subject are needed. In the future, the research topic will be even more interesting as equipment and materials will develop. This paper presents detailed printing parameters for all the materials used in the printing tests.

Abstract:
Purpose This paper aims to present a multi-material additive manufacturing (AM) process with a newly developed curing-on-demand method to fabricate a three-dimensional (3D) object with multiple material compositions. Design/methodology/approach Unlike the deposition-on-demand printing method, the proposed curing-on-demand printheads use a digital light processing (DLP) projector to selectively cure a thin layer of liquid photocurable resin and then clean the residual uncured material effectively using a vacuuming and post-curing device. Each printhead can individually fabricate one type of material using digitally controlled mask image patterns. The proposed AM process can accurately deposit multiple materials in each layer by combining multiple curing-on-demand printheads together. Consequently, a three-dimensional object can be fabricated layer-by-layer using the developed curing-on-demand printing method. Findings Effective cleaning of uncured resin is realized with reduced coated resin whose height is in the sub-millimeter level and improved vacuum cleaning performance with the uncleaned resin less than 10 µm thick. Also, fast material swapping is achieved using the compact design of multiple printheads. Originality/value The proposed multi-material stereolithography (SL) process enables 3D printing components using more viscous materials and can achieve desired manufacturing characteristics, including high feature resolution, fast fabrication speed and low machine cost.

This thesis presents the development of MultiFab, a multi-material 3D printing architecture that is high-resolution, scalable, and low-cost. MultiFab enables the 3D printing of parts with materials that interact optically and mechanically. The hardware is low-cost since it is built almost exclusively from off-the-shelf components. The system uses commercial piezoelectric printheads that enable multi-material 3D printing with a resolution of at least 40 [mu]m. This thesis presents the design and fabrication of MiniFab, a 3D printer that implements the MultiFab architecture, and its key subsystems, including novel material feeding and UV LED curing systems. Additionally, results show that the printer is capable of producing multi-material parts for a wide variety of applications..

The bounds of the design space for 3D-printed objects continue to rapidly extend as the library of printable materials continues to grow. This thesis explores printed objects uniquely enabled by the addition of a magnetic ink to the existing repertoire of materials for the MultiFab printer, a high-resolution, multi-material inkjet 3D printer. Magnetic nanoparticles, a base ink, and a dispersion method are selected to develop the magnetic ink. The ink is optimized for maximal magnetic content and its magnetic properties are characterized. A 9.7 ± 0.8 wt% magnetite ink with expected stability exceeding 10 days is achieved. Design, characterization, and validation of two small-scale multi-material actuators driven by magnetism is performed. The first actuator is a simple fixed cantilever, while the second is a tilting panel. More advanced structures and actuators are explored and are suggestive of an extremely wide scope for potential future applications. The fields of application shown for 3D-printable magnetic ink in a multi-material context range from biomimicry (e.g. stimuli-responsive surfaces) to optics and aerodynamics.

Material serves as the first touchpoint between an object and a person. In current product development, material together with color and finishing is regarded as a separate entity from the form and function design. Every material needs to be paired with a series of optimal manufacturing processes for the desired effect. In many cases, this is handled with material design specialists. People perceive a material primarily by its surface: chromatic, tactile, and decorative identity it displays or the temperature and hardness when touching it. Typically, this material surface can be viewed as a two-dimensional entity that reveals limited-expression and information to be delivered via human intervention. In this thesis, we propose to get away from surface obsession in object and industrial design, by adding another dimension to the material interface. By embedding information into three-dimensional matter, we introduce volumetric material: a new material organization that responds directly to the user intervention or the environment. With multi-material 3D printing, we envision a future in product development where the design of surface detail, texture, reflexivity can finally be merged with the overall product composition from the beginning of the design process. With voxel printing capability, we designed and tested material interface with depth and explored volumetric behavior that is both visually and functionally meaningful to the user, and discussed the results.

Tese de Doutoramento em Arquitetura, com a especialização em Desenho e Computação apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutor.
Arquitetos e engenheiros estão sob crescente pressão para melhorar a eficiência e a eficácia do setor da arquitetura, engenharia e construção, de forma a reduzir o impacto ambiental, o uso de materiais e os custos. A eficiência de recursos, baseada numa estratégia de economia circular, considera um uso eficiente da energia, assim como dos recursos naturais e materiais. A integração de tecnologias digitais nos processos de construção permitirá uma maior flexibilidade no projeto e customização, bem como a conceção de formas complexas e novos materiais. Nos últimos anos, o interesse no desenvolvimento de tecnologias de fabricação aditiva na construção cresceu, mas encontram-se limitadas ao projeto e fabrico de componentes físicos compostos por materiais com propriedades homogéneas, garantindo a segurança estrutural, mas negligenciando o uso eficiente de recursos. Para superar tais limitações, um novo sistema de fabricação aditiva foi desenvolvido para construção automatizada, permitindo a produção de materiais compósitos heterogéneos com composição espacial variável, através da replicação de processos naturais. Pretende-se, portanto, desenvolver um sistema que permita desenhar e produzir elementos de construção heterogéneos com maior desempenho. Foi desenvolvida uma ferramenta computacional, em Grasshopper, que permite a geração automática da composição do material e o controlo o equipamento de fabricação. A interface com o utilizador permite criar elementos de construção uni ou multimaterial com gradiente de porosidade ou de material, permitindo conceber o material em resposta a requisitos termomecânicos predefinidos, otimizando o seu desempenho. Um equipamento robotizado, composto por várias bombas de material, foi desenvolvido para produzir os elementos de construção heterogéneos gerados pela ferramenta computacional. A necessidade de novos materiais para viabilizar a fabricação aditiva exigiu a realização de trabalho experimental, no qual foram avaliadas as propriedades mecânicas e térmicas de várias misturas de betão de agregados finos contendo cortiça, fibras, basalto e outros resíduos industriais. Foram utilizadas diferentes percentagens de cortiça, uma matéria-prima leve, natural e sustentável, totalmente biodegradável, renovável e reciclável. As misturas de betão com maiores quantidades de cortiça apresentam menor condutividade térmica quando comparadas com as que possuem menor percentagem ou com as que não contêm cortiça, verificando-se igualmente uma redução significativa no peso do material. A utilização de um sistema de fabricação automática que permita a extrusão aditiva betão leve de composição ajustável para a produção de elementos de construção heterogénea poderá ser uma solução eficiente para reduzir os custos energéticos e proporcionar conforto térmico aos utilizadores dos edifícios.
ABSTRACT: Architects and engineers are under increasing pressure to improve the efficiency and effectiveness of the architecture, engineering and construction (AEC) sector, reducing environmental impacts, material use and costs. Resource efficiency, based on a circular economy strategy, considers an efficient use of energy, natural resources, and materials. The integration of digital technologies into construction processes will allow for a greater flexibility in design and customization, as well the emergence of complex shapes and new materials. In recent years, the interest in developing additive manufacturing (AM) technologies in the AEC has increased, though traditional AM technologies are limited to the design and fabrication of physical components with homogeneous material properties, assuring structural safety but with no efficient use of material resources. To overcome these limitations, an AM system was developed for automated fabrication, enabling the fabrication of heterogeneous composite materials with varying material distribution, simulating nature’s structural behavior. The aim is to design and fabricate functionally graded building components with increased performance. A design system, developed in grasshopper, was designed to generate the material composition variation and control the fabrication equipment. The user interface allows creating single or multi-material building components with pore size or material gradients, permitting to design the material in response to thermo-mechanical requirements, optimizing its performance. A multi-pump robot equipment was developed to produce the generated heterogeneous building components. It was necessary to develop printable materials to enable additive fabrication, so experimental work was carried out to assess the mechanical and thermal properties of fiber cement-based concrete mixtures containing cork, basalt and other residual waste. Different percentages of cork were used, as it is a natural and sustainable lightweight raw material, completely biodegradable, renewable, and recyclable. Results show that concrete mixtures with higher quantities of cork have lower thermal conductivity compared to the ones with less percentage or no cork, as well a significant reduction in material weight. The potential use of an AM system to produce printable functionally graded lightweight concretes can be an efficient solution to reduce energy costs and provide thermal comfort for building users.

This paper studies the two aspects of current problems that plagues the Prusa i3 MK3sprinters in possession of JTH and how to resolve them; to be able to get a reliable printoutputs from engineering grade materials apart from conventional materials like PLAand PETG. The second aspect being the implementation of multi material module 2.0S,hereafter referred to as MMU2s successfully by analyzing and testing the current modi-cations and upgrades currently in the community and suggest any further modications,if required, both in terms of hardware and software which is further discussed in theupcoming sections. At present, there are numerous design upgrades and modicationsover the stock parts in the community which claim to iron out the reliability issues ofthe multi material unit. But, the success rates of these modications and upgrades varywidely. We tend to look at some of these modications which helps in eliminating theissues associated with the unit while getting it to produce results in a consistent and reliablemanner. The engineering grade thermoplastics which the university plan to use werealso taken into account to implement in the printers once the MMU2s setup was testedfor reliability. The objective also to create a successful prole sets by tweaking variousparameters in the slicing software for the aforementioned engineering grade materials sothat a ready-to-print prole is available for the corresponding material. During the course of project work, the reliability of the multi material unit was increasedby upgrading few of the components such as idler barrel and selector. Fine tuningof software parameters led to the error free running of the MMU unit by which extensivetesting was possible. Furthermore, engineering grade thermoplastics was able to betested and implemented on the current setup by making use of these software and hardwarechanges. Finally, extensive testing of the multi material unit was done coupled withengineering grade thermoplastics which yielded successful results and the congurationsettings saved for future use in the university.

Abstract:
The work herein is, in part, motivated by the idea of creating optimized, actuating structures using additive manufacturing processes (AM). By developing a consistent, repeatable method for designing and manufacturing multi-material compliant mechanisms, significant performance improvements can be seen in application, such as increased mechanism deflection. There are three distinct categories of research that contribute to this overall motivating idea: 1) investigation of an appropriate multi-material topology optimization process for multi-material jetting, 2) understanding the role that manufacturing constraints play in the fabrication of complex, optimized structures, and 3) investigation of an appropriate process for embedding actuating elements within material jetted parts. PolyJet material jetting is the focus of this dissertation research as it is one of the only AM processes capable of utilizing multiple material phases (e.g., stiff and flexible) within a single build, making it uniquely qualified for manufacturing complex, multi-material compliant mechanisms. However, there are two limitations with the PolyJet process within this context: 1) there is currently a dearth of understanding regarding both single and multi-material manufacturing constraints in the PolyJet process and 2) there is no robust embedding methodology for the in-situ embedding of foreign actuating elements within the PolyJet process. These two gaps (and how they relate to the field of compliant mechanism design) will be discussed in detail in this dissertation. Specific manufacturing constraints investigated include 1) "design for embedding" considerations, 2) removal of support material from printed parts, 3) self-supporting angle of surfaces, 4) post-process survivability of fine features, 5) minimum manufacturable feature size, and 6) material properties of digital materials with relation to feature size. The key manufacturing process and geometric design factors that influence each of these constraints are experimentally determined, as well as the quantitative limitations that each constraint imposes on design.

Abstract:
The overall goal of this research work is to enhance the capabilities of large-format, polymer material extrusion, additive manufacturing (AM) systems. Specifically, the aims of this research are to (1) Construct, and develop a robust workflow for, a large-format, robotic, AM system; (2) Develop an algorithm for determining and relaying proper rotation commands for 5 degree of freedom (DoF) multi-axis deposition; and (3) Create a method for printing a removable support material in large-format AM. The development and systems-integration of a large-format, pellet-fed, polymer, material extrusion (ME), AM system that leverages an industrial robotic arm is presented. The robotic arm is used instead of the conventional gantry motion stage due to its multi-axis printing ability, ease of tool changes for multi-material deposition and/or subtraction, and relatively small machine footprint. A novel workflow is presented as a method to control the robotic arm for layer-wise fabrication of parts, and several machine modifications and workflow enhancements are presented to extend the multi-axis manufacturing capabilities of the robot. This workflow utilizes existing AM slicers to simplify the motion path planning for the robotic arm, as well as allowing the workflow to not be restricted to a single robotic deposition system. To enable multi-axis deposition, a method for generating tool orientations and resulting deposition toolpaths from a geometry's STL file was developed for 5-DoF conformal printing and validated via simulation using several different multi-DOF robotic arm platforms. Furthermore, this research proposes a novel method of depositing a secondary sacrificial support material was created for large-format AM to enable the fabrication of complex geometries with overhanging features. This method employs a simple tool change to deposit a secondary, water-soluble polymer at the interfaces between the part and supporting structures. In addition, a means to separate support material into smaller sections to extend the range of geometries able to be manufactured via large-format AM is presented. The resultant method was used to manufacture a geometry that would traditionally be considered unprintable on conventional large-format AM systems.
Master of Science
Additive manufacturing (AM), also known as 3D printing, is a method of manufacturing objects in a layer-by-layer technique. Large-format AM is typically defined as an AM system that can create an object larger than 1 m3. There are only a few manufacturers in the world of these systems, and all currently are built on gantry-based motion stages that only allow movement of the printer in three principal axes (X, Y, Z). The primary goal of this thesis is to construct a large-format AM system that uses a robotic arm to enable printing in any direction or orientation. The use of an industrial robotic arm enables printing in multiple planes, which can be used to print structures without support structures, print onto curved surfaces, and to purt with curved layers which produces a smoother external part surface. The design of the large-format AM system was validated through successful printing of objects as large as 1.0x0.5x1.2 m, simultaneous printing of a sacrificial support material to enable overhanging features, and through completing multi-axis printing. To enable multi-axis printing, an algorithm was developed to determine the proper toolpath location and relative orientation to the part surface. Using a part's STL file as input, the algorithm identifies the normal vector at each movement command, which is then used to calculate the required tool orientation. The tool orientations are then assembled with the movement commands to complete the multi-axis toolpath for the robot to perform. Finally, this research presents a method of using a second printing tool to deposit a secondary, water-soluble material to act as supporting structures for overhanging and bridging part features. While typical 3D printers can generally print sacrificial material for supporting overhangs, large-format printers produce layers up to 25 mm wide, rendering any support material impossible to remove without post-process machining. This limits the range of geometries able to be printed to just those with no steep overhangs, or those where the support material is easily reachable by a tool for removal. The solution presented in this work enables the large scale AM processes to create complex geometries.

Abstract:
A novel paste deposition process was developed to widen the range of possible materials and applications. This experimental process developed an increasingly complex series of additive manufacturing machines, resulting in new combinations of novel materials and deposition paths without sacrificing many of the design freedoms inherit in the craft process. The investigation made use of open-source software together with an approach to programming user originated infill geometries to form structural parts, differing from the somewhat automated processing by 'closed' commercial RP systems. A series of experimental trials were conducted to test a range of candidate materials and machines which might be suitable for the PDM process. The combination of process and materials were trailed and validated using a series of themed case studies including medical, food industry and jewellery. Some of the object created great interest and even, in the case of the jewellery items, won awards. Further evidence of the commercial validity was evidenced through a collaborative partnership resulting in the development of a commercial version of the experimental system called Newton3D. A number of exciting potential future directions having been opened up by this project including silicone fabrics, bio material deposition and inclusive software development for user originated infills and structures.

Abstract:
AbstractThis work introduces multi-material liquid printing as an enabling technology for designing programmed shape-shifting silicones. The goal of this research is to provide a readily available, scalable and customized approach at producing responsive 4D printed structures for a wide range of applications. Hence, the methodology allows customization at each step of the procedure by intervening either on the material composition and/or on the design and fabrication strategies for the production of responsive components. A significant endeavour is initiated to develop and engineer two different material systems that enable shape-shifting: silicone-ethanol composites and polyvinyl siloxane swelling rubbers. The printed samples successfully comply with the expected swelling behaviour through a variety of printed test patterns.

Abstract:
Digital light processing (DLP) three-dimensional (3D) printing is a type of stereolithography (SLA) process that uses a digital projector to selectively cure resin according to a mask image. Each exposure solidifies a planar component of the printed part, allowing full layers to be cured at once. The DLP approach produces better quality parts at a faster rate compared to other 3D printing methods. One of the challenges with DLP printing is the difficulty of incorporating multiple materials within the same part. As the part is cured within a liquid basin, resin switching introduces issues of cross-contamination, layer height variability, and significantly increased print times. In this paper, a novel technique for printing with multiple materials using the DLP method is introduced. The material handling challenges are addressed with the design of a material swapping mechanism, a material tower, and an active part cleaning system. The material tower is a compact design to facilitate the storage and retrieval of different materials during the printing process. A spray mechanism is used for cleaning excess resin from the part between material changes. Challenges encountered within the 3D printing research community are addressed, with a focus on improving the shortcomings of modern multi-material DLP printers.

Abstract:
Multi-scale and multi-material 3D printing is new frontier in additive manufacturing. It has shown great potential to implement the simultaneous and full control for fabricated object including external geometry, internal architecture, functional surface, material composition and ratio as well as gradient distribution, feature size ranging from nano, micro, to marco-scale, embedded components and electro-circuit, etc. Furthermore, it has the ability to construct the heterogeneous and hierarchical structured object with tailored properties and multiple functionalities which cannot be achieved through the existing technologies. That paves the way and may result in great breakthrough in various applications, e.g., functional tissue and organ, functionally graded material/structure, wearable devices, soft robot, functionally embedded electronics, metamaterial, multi-functionality product, etc. However, very few of the established additive manufacturing processes have now the capability to implement the multi-material and multi-scale 3D printing. This paper presented a single nozzle-based multi-scale and multi-material 3D printing process by integrating the electrohydrodynamic jet (E-jet) printing and the active mixing multimaterial nozzle. The proposed AM technology has the capability to create multifunctional heterogeneously structured objects with control of the macro-scale external geometry and micro-scale internal structures as well as functional surface features, particularly, the potential to dynamically mix, grade and vary the ratios of different materials. An active mixing nozzle, as a core functional component of the 3D printer, is systematically investigated by combining with the theoretical analysis, numerical simulation and experimental verification. The study aims at exploring a feasible solution to implement the multi-scale and multi-material 3D printing at low cost.

Abstract:
Abstract 3D printing is a promising technique to fabricate flexible parts and reduce the supply chain. Various materials, such as metal powders, plastics, ultraviolet (UV) sensitive resins, can be fabricated from 3D printing and form the final printed part. Currently, most researchers either focus on exploring printable materials with good property or focus on the process quality control given a certain type of material. However, for many 3D printing processes, the printing process and product properties are dependent on both the material properties and process settings. To the best of the authors’ knowledge, the quantitative analysis of the interactions of material properties and printing process settings are rarely studied. In this paper, we treat the material preparation and 3D printing as different manufacturing stages, and we explore the multi-stage effects in 3D printing. In particular, we add carbon fiber to the CLEAR resin to alter the material properties for a stereolithography (SLA) 3D printing process. It is observed that the part properties are jointly affected by material properties and printing process settings. Therefore, the material property and process settings should be jointly considered for optimizing 3D printing processes.
