Abstract:
Printers have become ubiquitous in modern office spaces, and their placement in these spaces been guided more by accessibility than security. Due to the proximity of printers to places with potentially high-stakes information, the possible misuse of these devices is concerning. We present a previously unexplored covert channel that effectively uses the sound generated by printers with inkjet technology to exfiltrate arbitrary sensitive data (unrelated to the apparent content of the document being printed) from an air-gapped network. We also discuss a series of defense techniques that can make these devices invulnerable to covert manipulation. The proposed covert channel works by malware installed on a computer with access to a printer, injecting certain imperceptible patterns into all documents that applications on the computer send to the printer. These patterns can control the printing process without visibly altering the original content of a document, and generate acoustic signals that a nearby acoustic recording device, such as a smartphone, can capture and decode. To prove and analyze the capabilities of this new covert channel, we carried out tests considering different types of document layouts and distances between the printer and recording device. We achieved a bit error ratio less than 5% and an average bit rate of approximately 0.5 bps across all tested printers at distances up to 4 m, which is sufficient to extract tiny bits of information.

Abstract:
Fused deposition modelling (FDM) 3D printers have the highest annual growth of 21.15% in the field of 3D printing. FDM desktop 3D printers account for 23.69% of FDM printers. The major drawback of FDM desktop printers is product accuracy, which is particularly pronounced when dimensionally inaccurate and multi-part printed products need to be fit together into a functional assembly. The research presented in this paper aims to determine the accuracy limits of FDM 3D printers when producing elements for assembly using a 3D printer in a tolerance-fit system. A novel method of computer-aided design (CAD) based on ISO 286 and the systematic calibration procedure of 3D printers were presented to achieve the dimensional accuracy of 3D printed parts. For this purpose, a set of nominal dimensions within the clearance fit was selected, and various CAD models were created according to the ISO 286 system of limits and fits. The CAD Slicer software–3D printer interaction was systematically examined for the best hardware and software features. It was found that the Horizontal Expansion parameter should be 0.0 mm and the Hole Horizontal Expansion parameter should be 0.13 mm. The Linear Advance factor was found to be 25. The measurement results showed that the desired tolerance ranges, system, and type of clearance fit could be achieved with a desktop 3D printer. The roundness tolerance for all clearance fits and shaft tolerance ranges in the hole base system was determined to join the parts into a clearance fit.

Abstract: Mozza Computer is a computer shop that sells computers, printers, computer spare parts, computer accessories and provides computer and printer services. So far, the service process has been carried out by consumers coming directly to Mozza Computer with computers or printers that are having problems, then the service division will first check whether the device can be worked on directly or not. This requires quite a long time because consumers who come must queue because of limited employees to check for damage to the computer. An expert system for diagnosing computer hardware damage using the Case Based Reasoning Method on Mozza Computer was made to serve as a tool in making it easier to find out damage to computer hardware through an expert system application. In the process of identifying hardware damage, an analysis of the latest data will be carried out with case data that has occurred for a long time to obtain a percentage level of confidence in the damage. Based on the results of the tests that have been carried out, the functionality of the expert system for diagnosing computer hardware damage using the Case Based Reasoning Method on Mozza Computer has gone well as expected and is able to provide information on the results of consulting computer hardware damage

Abstract:
Purpose This paper aims to present a monitoring system and the usage of a robotic arm to remove finished parts of a three-dimensional (3D) printer build plate, enabling 3D printers to continuously build a sequence of parts. Design/methodology/approach The system relies on a 2-degree of freedom planar manipulator. The moment to remove printed parts from the printer build plate can be determined based on direct communication with the 3D printer control software or using information from a computer vision system that applies background subtraction and Speeded up Robust Features methods. Findings The proposed system automatically detects the end of standard 3D print jobs and controls the robotic arm to remove the part. Research limitations/implications Lighting variation can deteriorate the response of the computer vision system, which can be minimized using a controlled illumination environment. In addition, the printer build plate edges must be free so the parts can slip off the printer build plate when the robot pushes them out. Practical implications The system enables a more practical and automatized usage of 3D printers, reducing the need of human operators. Social implications The proposed system can reduce work hours of laboratory personnel, as there is no need to remove the printed parts manually before another job starts. Originality/value Computer vision system monitors the printing process and the automation system that enables continuous sequential 3D printing of parts. A prototype is described, which can be easily replicated with low cost parts.

Abstract:
The application of mechatronic systems is very topical today. Today, mechatronic systems are applied in all areas, so today systems are also being developed that enable fast and simple production of products. Today's mechatronic systems that are supported by computers enable the development, easy and fast production of prototypes and products. Two technologies that are widely used are 3D printers and scanners. 3D printers allow a virtually developed product to be turned into a physical model, while the application of a 3D scanner allows a physical model to be turned into a virtual model on a computer. In this paper, a comparative analysis of two types of printers and their software was performed. They differ according to their working principle. In addition to the working principle, an example of the difference between the software used to write the G code to drive the printing process of 3D printer.

Abstract:
The recent development of RepRap style 3D printers has made additive manufacturing technology available to the public at a low cost. While these 3D printers are being used for a variety of purposes, one of the main applications is prototyping in design projects. The quality of the 3D-printed parts has been a concern in such cases. Many variables within these printers’ operation can be varied to obtain optimum print quality. This study explores a setup that uses externally induced mechanical vibrations to the nozzle tip as a potential method to improve the quality of 3D-printed parts. Induced vibration is expected to decrease the porosity of printed parts and enhance the cohesion between print beads, ultimately improving their mechanical properties. The objective is to understand the prints’ positional accuracy, porosity, and mechanical properties with the added vibration and then to determine the optimum vibration level to achieve the best quality prints. While previous studies have explored the role of induced vibration on the mechanical properties of printed parts, the novelty of this work lies in the determination of the positional accuracy of those parts and the determination of optimum vibration levels to achieve desired properties. For positional accuracy, the extruder filament is replaced with a pointed-tip pen that can mark the exact location where the printer delivers the material. A comparison between the locations marked by the pen with and without vibrations shows that the errors induced by the added vibration are not significantly different from those caused by the uncertainties of the printer itself. Based on the tensile tests of the printed specimens, it is concluded that the parts printed with induced vibrations have improved mechanical properties. The printed parts’ porosity is reduced significantly due to the induced vibrations. Further, this study also explores the optimum motor speeds to achieve a uniform distribution of material. It determines medium motor speeds that provide a maximum vibration amplitude, which is more desirable for a consistent infill.

Abstract:
The ability to print what is seen on a computer screen so that it matches a printer (color matching) confounds even the most experienced. That's because computer monitors, even from the same manufacturer, cannot be made to display colors identically. Also, printers from different manufacturers contain several “libraries” of replacement colors in order to replace pixel values in an image from light (red, green and blue: RGB) to the primary colors for pigments (cyan, magenta, yellow and black: CMYK). Cameras use the primary colors for light and that is the way the digital image is stored and displayed; printers use the primary colors for pigments in ink. Thus, a printer must have a pixel by pixel list of replacement CMYK values for every RGB value in any image for that manufacturer's idea of faithful color matching.

Abstract:
The promising technology depend on using 3D printers' machines (3DPs) might be considered a modern approach in drug industry and delivery. A 3D printer may define as a machine which fabricates 3D models or products using computer aided design (CAD) software programs. These printers can create a single copy of an item that is too complicated and very difficult to produce by using traditional manufacturing methods. Moreover, it has ability to make products with complex internal structure geometries with lower cost and time. Recently, 3D printers have been involved into printing bio-products, custom pills and organs for transplant. This review presents the types of 3DPs suitable for drug industry and delivery. There are several types of 3DPs are used in pharmaceutical fields including inkjet (IK) printers, fused filament (FF) type printers, extrusion and hot melt extrusion 3D printing, sintering by selective kind of laser (SLS), Stereolithography (SLA), melting by micro selective laser (SLM), binder applied jetting printing (BJ) and the laminated object engineering manufacturing (LOM).

Font and graphics antialiasing are often used methods of enhancing the output quality of video monitors. The same techniques also can enhance the quality of laser printer output. Since the laser printing process and the monitor display process differ radically, the assumptions made for antialiasing on monitors are reexamined. Raster scanning, laser modulation, xerographic transfer, information transfer, and computation are examined in the context of laser printer antialiasing. Past work on antialiasing algorithms is evaluated. A practical method of performing anti-aliasing of text, graphics, and images is developed. Standard antialiasing scan conversion algorithms are adapted to function on two dimensional binary bitmaps of vector data. Computation issues are discussed, and a fast localized scan conversion operation based on statistical models is developed and evaluated. Finally, an architecture for the high bandwidth modulation of the laser by both power and time is developed, implemented, and evaluated.

Thanks to today's digital imaging technology, any ten year old child with basic computer skills can create convincing counterfeit currency. It comes as no surprise that as output quality and costs have improved in ink-jet printers, there has been a corresponding surge in digital counterfeiting of security documents. The design of a system, through which a printer can recognize a security or other protected document though identification of a watermark, presents a challenge for the application of information hiding techniques. The marking should be strong enough to provide certainty that a document was intentionally marked and robust enough to withstand the transformations inherent in the scanning and printing process. Using an extended spread­spectrum technique, a small one-dimensional thread encoded with a known multi-bit signature is generated. If the printer detects a match, printing halts and a warning message is output to the user. By applying several such threads at varying orientations, this can provide an effective first line of defense against the casual digital counterfeiter.

Abstract:

When dot-matrix characters are rotated, as might be the case in a moving map display, their dot-matrix patterns are distorted and their legibility is thus affected. In this experiment, 16 subjects performed a random search task, in which they were asked to look for a target in a random character pattern. The independent variables were the direction (clockwise or counterclockwise) and the angle of stimulus image rotation, and the target character's distance from the center of screen, which was also the center of rotation; the dependent variables were response time and response correctness.

Significant effects were found in the angle of rotation, the target character's distance from the center, and the target character. The results indicate that (1) no angle-dependent mechanism is involved in performing this task and the angle of rotation influences recognition mainly through the distortion of dot-matrix patterns, (2) the target character's (radial) distance from the center of screen is the determining factor for search time, while the x and y coordinates of the target contributed to dot-matrix pattern distortion, and (3) the target characters interacted differently with the angle and distance factors to determine the extent of distortion and their legibility.

Means to quantify the extent of distortion were discussed and the direction for future research is offered.

Abstract:
The proliferation of electronic equipment that is permanently connected to the grid causes significant parasitic losses. Yet, the design of power supplies for PCs, servers, multi-function printers, etc, is governed by the cost and component specifications at the peak operating point as well as the thermal management of the power supply itself. Most power supplies have lower efficiencies at light loads than at their rated loads. If the unit spends most of its time at the light load operating point, then the energy consumption will be much higher compared to a situation where the power supply is optimized for overall energy consumption with a specified load cycle. Considering that most electronic appliances are produced in high volume, the use of power supplies that permit easy custom design makes sense from the standpoint of energy efficiency. Over the past few years, multiple topological changes and design changes that aim to improve the efficiency of the power supplies have been proposed. However, their proliferation in low cost consumer electronics has been limited primarily by their high costs, additional area overhead and incompatibility with existing power supply converter topologies. As a part of this Master's thesis research work, a business case is first proposed to show that a market for low cost and high power rating electronic devices that exhibits high power efficiency exists. Then a novel yet simple, low cost device(SSSR) is proposed to improve the efficiency of existing power supplies without effecting major changes to their existing design. Our claims are backed up by simulation results and a working prototype. Finally, a ROI model is presented to showcase the effectiveness of the proposed solution in today's consumer market.

Abstract:
The main goal of this doctoral thesis is the development and optimization of inkjet- based technologies for hybrid electronic circuits manufacturing, as well contribute on the development of the incoming low cost electronics. Regarding that, a novel solution for connecting regular SMDs and standard silicon SMD packages by inkjet printing is proposed. The novel connecting method allows the assembling at very low temperatures, and thus assures the compatibility with the incoming substrates. Electrical contact resistance and shear strength measurements performed by silver nanoparticle- based ink are comparable to benchmark connecting materials. In sum up, flexible hybrid circuit is successfully manufactured by silver nanoparticle-based ink on paper, where different SMDs size-shaped are assembled demonstrating the reliability and feasibility of the proposed method. Another objective of the work is to apply and adapt the print-on-slope technique to assemble directly the silicon dies on PCB, proposing a novel strategy to overcome the drawbacks of the wire bonding in the Conductive AFM measurements. Then, a novel setup for conductive AFM mode 2D materials characterization was manufactured. The 2D connection on ramp-shape terminations gives a better functionality than current wire bonding connections. The AFM tip moves over the silicon die without physical obstruction, giving a unique solution at this novel method to characterize the material degradation. In the field of multilayer hybrid PCB manufacturing, the goal is to prove the potentiality of different metal-insulator-metal structures inkjet-printed and evaluate their reliability and the electrical performance for low cost multilayer circuit based on paper substrate. In the light of the results, heterogeneous structures combining inorganic and organic dielectric material, where PVP fills the inorganic cracks and voids, possess a similar and outstanding feasibility in both paper and glass substrate without short-circuits. The greatest achievement of this work is the development and optimization of a novel capillarity-assisted SMD assembling method for the manufacturing of hybrid circuits inkjet-printed. In addition, taking advantage of print-on-slope technique, direct assembling of silicon die integrated circuits to PCB is successfully applied. Moreover, heterogeneous structures inkjet-printed open new solutions for multilayer hybrid circuits.
L’objectiu principal d’aquesta tesi doctoral és el desenvolupament i l’optimització de tecnologies basades en injecció de tinta per a la fabricació de circuits electrònics híbrids, així com contribuir al desenvolupament de l’electrònica de baix cost. Es proposa una nova solució per connectar els dispositius de muntatge superficial (SMDs) mitjançant impressió de tinta amb càrrega de nanopartícules de plata. El nou mètode de soldadura permet fer la connexió a temperatures molt baixes i, per tant, assegura la compatibilitat amb els substrats tèrmicament menys resistents. Les mesures elèctriques de resistència de contacte i les mesures mecàniques de resistència de cisalla obtingudes són comparables a als obtinguts amb materials de connexió convencionals. En definitiva, s’ha aconseguit fabricar circuits hídrids flexibles amb èxit mitjançant tinta basada en nanopartícules de plata sobre paper, on diferents dimensions de SMDs han estat soldats, la qual cosa demostra la fiabilitat i la viabilitat del mètode proposat. Un altre dels objectius del treball és aplicar i adaptar la tècnica d'impressió mitjançant rampes per muntar directament microelectrònica sobre circuits impresos. Mitjançant aquesta tècnica, s’han superat els inconvenients provocats per les unions de fil d’or al realitzar mesures conductives mitjançant AFM. Així, s’ha utilitzat una nova estratègia per a la caracterització de materials 2D mitjançant la tècnica de CAFM. Les connexions 2D proporcionen una millor funcionalitat que les connexions actuals mitjançant fils. De fet, la punta AFM es mou sobre la mostra de silici sense obstrucció física, donant una solució única en aquest mètode per caracteritzar la degradació del material. En el camp de la fabricació de PCB híbrida multicapa, l'objectiu és provar la potencialitat de diferents estructures metall-aïllant-metall impreses mitjançant inkjet i avaluar la seva fiabilitat i les propietats elèctriques per a un circuit multicapa de baix cost basat en substrat de paper. A la vista dels resultats, les estructures heterogènies que combinen material dielèctric inorgànic i orgànic, on el PVP omple les esquerdes i els buits de les capes de material inorgànic, presenten unes bones prestacions elèctriques i tenen una viabilitat similar tant en paper com en substrat de vidre sense curtcircuits. La fita més rellevant d’aquest treball és el desenvolupament i l’optimització d’un nou mètode de soldadura de SMDs mitjançant inkjet i assistit per capil·laritat. Aprofitant la tècnica d'impressió sobre rampes, s’ha aconseguit muntar directament circuits integrats de silici sobre PCBs. A més, les estructures heterogènies impreses per injecció de tinta obren noves solucions per a circuits híbrids multicapa.

Abstract:
Computer generated holograms and diffractive optical elements are desired for a wide range of applications including optical interconnects, pattern recognition filters, binary phase filters, laser beam combiners, and displays. However, methods to design and produce them have been cumbersome. Typically, software been written anew for each application in Fortran on large computers and used to address e-beam lithography devices (1). This process results in submicron resolution but is slow, inflexible and costly. Only recently have efforts begun to bring to diffractive optics the highly developed computer aided design tools available for other engineering disciplines (2). Research and practical applications of diffractive/holographic elements of all kinds would be accelerated if there existed a simple, quick, low cost and easy to use method for creating optical patterns even of moderate resolution (1-3 microns).

Abstract:
Three-dimensional printing or rapid prototyping has had a significant impact on manufacturing and educational environments. Manufacturing organizations can now cheaply and quickly create prototypes to provide information on sizes, tolerances, tolerance stack-ups, and assembly. Educational institutions may utilize 3-D printers in much the same ways. Students enhance computer-aided design (CAD) learning by actually making the parts they design and checking assembly operations. From a metrology and GD&T perspective, 3-D printers are also employed to enhance the learning of these topics. Reverse engineering projects are conducted where students use metrology tools to measure a part or assembly, model the part on a computer using CAD, print the part using a 3-D printer, and then measuring the printed part for comparison to the original. As part of the process, students are asked to develop a measuring process that could be employed during an actual manufacturing process of the part including determining the critical dimensions and tools required to measure those dimensions. Additionally, students are required to create 5 GD&T specifications for the part and determine the best way to inspect those specifications.

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:
Additive manufacturing (3D printing) is a class of manufacturing processes where material is deposited in a layer-by-layer fashion to fabricate a three-dimensional part directly from a computer-aided design (CAD) model. With a current market share of 44%, thermoplastic-based additive manufacturing such as fused deposition modeling (FDM) is a prevailing technology. A preliminary extrusion process is required to produce thermoplastic filaments for use in FDM 3D printers. It is crucial that extruded filament must have constant dimensional accuracy for FDM 3D printers to produce the desired object with precision. In this study, carbon fibers were blended with acrylonitrile butadiene styrene (ABS) thermoplastics to produce carbon fiber reinforced ABS filaments in order to improve the mechanical properties of FDM-printed objects. During filament extrusion, three process variables showed significant effects on filament diameter, expansion percentage, and extrusion rate. These process variables included carbon fiber content, extrusion temperature, and nozzle size. The objective of this study is to test the feasible ranges of these process variables and to investigate their effects on filament extrusion. Results of this study will provide knowledge on quality improvement of carbon fiber reinforced ABS filament extrusion for additive manufacturing.

Abstract:
The original objectives of this research project were to: (1) develop immunoassays, photometric sensors, and electrochemical sensors for real-time measurement of progesterone and estradiol in milk, (2) develop biosensors for measurement of caseins in milk, and (3) integrate and adapt these sensor technologies to create an automated electronic sensing system for operation in dairy parlors during milking. The overall direction of research was not changed, although the work was expanded to include other milk components such as urea and lactose. A second generation biosensor for on-line measurement of bovine progesterone was designed and tested. Anti-progesterone antibody was coated on small disks of nitrocellulose membrane, which were inserted in the reaction chamber prior to testing, and a real-time assay was developed. The biosensor was designed using micropumps and valves under computer control, and assayed fluid volumes on the order of 1 ml. An automated sampler was designed to draw a test volume of milk from the long milk tube using a 4-way pinch valve. The system could execute a measurement cycle in about 10 min. Progesterone could be measured at concentrations low enough to distinguish luteal-phase from follicular-phase cows. The potential of the sensor to detect actual ovulatory events was compared with standard methods of estrus detection, including human observation and an activity monitor. The biosensor correctly identified all ovulatory events during its testperiod, but the variability at low progesterone concentrations triggered some false positives. Direct on-line measurement and intelligent interpretation of reproductive hormone profiles offers the potential for substantial improvement in reproductive management. A simple potentiometric method for measurement of milk protein was developed and tested. The method was based on the fact that proteins bind iodine. When proteins are added to a solution of the redox couple iodine/iodide (I-I2), the concentration of free iodine is changed and, as a consequence, the potential between two electrodes immersed in the solution is changed. The method worked well with analytical casein solutions and accurately measured concentrations of analytical caseins added to fresh milk. When tested with actual milk samples, the correlation between the sensor readings and the reference lab results (of both total proteins and casein content) was inferior to that of analytical casein. A number of different technologies were explored for the analysis of milk urea, and a manometric technique was selected for the final design. In the new sensor, urea in the sample was hydrolyzed to ammonium and carbonate by the enzyme urease, and subsequent shaking of the sample with citric acid in a sealed cell allowed urea to be estimated as a change in partial pressure of carbon dioxide. The pressure change in the cell was measured with a miniature piezoresistive pressure sensor, and effects of background dissolved gases and vapor pressures were corrected for by repeating the measurement of pressure developed in the sample without the addition of urease. Results were accurate in the physiological range of milk, the assay was faster than the typical milking period, and no toxic reagents were required. A sampling device was designed and built to passively draw milk from the long milk tube in the parlor. An electrochemical sensor for lactose was developed starting with a three-cascaded-enzyme sensor, evolving into two enzymes and CO2[Fe (CN)6] as a mediator, and then into a microflow injection system using poly-osmium modified screen-printed electrodes. The sensor was designed to serve multiple milking positions, using a manifold valve, a sampling valve, and two pumps. Disposable screen-printed electrodes with enzymatic membranes were used. The sensor was optimized for electrode coating components, flow rate, pH, and sample size, and the results correlated well (r2= 0.967) with known lactose concentrations.

Abstract:
South Africa is a country with significant socio-economic development challenges, with the majority of South Africans having limited or non-existent access to basic infrastructure, services, housing and socio-economic opportunities etc. The urban housing backlog currently exceeds 2.4 million houses, with many families living in informal settlements. The Breaking New Grounds Policy, 2014 for the creation of sustainable human settlements, acknowledges the challenges facing human settlements, such as, decreasing human settlements grants allocation, increasing housing backlog, mushrooming of informal settlements and urbanisation. The White Paper on Science, Technology and Innovation (STI), 2019 notes that South Africa has not yet fully benefited from the potential of STI in addressing the socio-economic challenges and seeks to support the circular economy principles which entail a systematic change of moving to a zero or low waste resource-efficient society. Further to this, the Science and Technology Roadmap’s intention is to unlock the potential of South Africa’s human settlements for a decent standard of living through the smart uptake of science, technology and innovation. One such novel technology is the Three-Dimensional (3D) printing technology, which has produced numerous incredible structures around the world. 3D printing is a computer-controlled industrial manufacturing process which encompasses additive means of production to create 3D shapes. The effects of such a technology have a potential to change the world we live in and could subsequently pave the roadmap to improve on housing delivery and reduce the negative effects of conventional construction methods on the environment. To this end, the Academy of Science of South Africa (ASSAf), in partnership with the Department of Science and Innovation (DSI) and the University of Johannesburg (UJ) hosted the second virtual IID seminar titled: Exploring the Prospects of Using 3D Printing Technology in the South African Human Settlements, on 01 March 2021 to explore the potential use of 3D printing technology in human settlements. The webinar presented preliminary findings from a study conducted by UJ, addressing the following topics: 1. The viability of 3D printing technology 2. Cost comparison of 3D printed house to conventional construction 3. Preliminary perceptions on 3D printing of houses Speakers included: Dr Jennifer Mirembe (NDoHS), Dr Jeffrey Mahachi, Mr Refilwe Lediga, Mr Khululekani Ntakana and Dr Luxien Ariyan, all from UJ. There was a unanimous consensus that collaborative efforts from all stakeholders are key to take advantage of this niche technology. @ASSAf_Official; @dsigovza; @go2uj; @The_DHS; #SA 3D_Printing; #3D Print_Housing; #IID
