Abstract:
Background: The aim of this study is to evaluate the accuracy of a Liquid Crystal Display (LCD) 3D printer compared to a Direct Light Processing (DLP) 3D printer for dental model printing. Methods: Two different printers in terms of 3D printing technology were used in this study. One was a DLP 3D printer and one an LCD 3D printer. The accuracy of the printers was evaluated in terms of trueness and precision. Ten STL reference files were used for this study. For trueness, each STL file was printed once with each 3D printer. For precision, one randomly chosen STL file was printed 10 times with each 3D printer. Afterward, the models were scanned with a model scanner, and reverse engineering software was used for the STL comparisons. Results: In terms of trueness, the comparison between the LCD 3D printer and DLP 3D printer was statistically significant, with a p-value = 0.004. For precision, the comparison between the LCD 3D printer and the DLP 3D printer was statistically significant, with a p-value = 0.011. Conclusions: The DLP 3D printer is more accurate in terms of dental model printing than the LCD 3D printer. However, both DLP and LCD printers can accurately be used to print dental models for the fabrication of orthodontic appliances.

Abstract:
This article proposes a method for assessing the competitiveness of building 3D printers based on a comparison of their technical and technological characteristics and economic parameters. The methodology implements an integrated approach that takes into account a large number of comparison parameters of a different nature based on the use of relative indicators. The calculation takes into account the design characteristics of printers, the characteristics of the manufacturability of the printing process, the characteristics of printed building objects and the economic parameters of printers. So, for low-rise construction, the essential parameters are: printing speed, the ratio of the print area and the overall dimensions of the printer, the ability to work with low-flow mixtures and with various building mixtures without readjustment, reducing the defectiveness of the printed layer and energy consumption. The most competitive is the printer that provides more units of useful effect, determined by a set of technical and technological characteristics, per unit of costs associated with the purchase of a printer, its energy consumption, the laboriousness of maintenance and installation and dismantling at a construction site. As a result of assessing the competitiveness of various types of printers, it was revealed that the leader for low-rise construction is the portal printer BOD2 2-2-2 of the Danish company COBOD BOD2. For printing building products and structures in a production environment, the FIXED robotic arm from the Netherlands has a competitive advantage. CyBe Construction. The considered approach to assessing the competitiveness of building 3D printers is of practical interest to their manufacturers. The new knowledge about the significance of the design solutions of 3D printers, obtained as a result of the implementation of the proposed methodology, creates strategic guidelines for domestic manufacturers.

Abstract:
With the advent of 3D printing technologies in dentistry, the optimization of printing conditions has been of great interest, so this study analyzed the accuracy of 3D-printed temporary restorations of different sizes produced by digital light processing (DLP) and liquid crystal display (LCD) printers. Temporary restorations of 2-unit, 3-unit, 5-unit, 6-unit, and full-arch cases were designed and printed from a DLP printer using NextDent C&B or an LCD printer using Mazic D Temp (n = 10 each). The restorations were scanned, and each restoration standard tessellation language (STL) file was superimposed on the reference STL file, by the alignment functions, to evaluate the trueness through whole/point deviation. In the whole-deviation analysis, the root-mean-square (RMS) values were significantly higher in the 6-unit and full-arch cases for the DLP printer and in the 5-unit, 6-unit, and full-arch cases for the LCD printer. The significant difference between DLP and LCD printers was found in the 5-unit and full-arch cases, where the DLP printer exhibited lower RMS values. Color mapping demonstrated less shrinkage in the DLP printer. In the point deviation analysis, a significant difference in direction was exhibited in all the restorations from the DLP printer but only in some cases from the LCD printer. Within the limitations of this study, 3D printing was most accurate with less deviation and shrinkage when a DLP printer was used for short-unit restorations.

Abstract:
This study quantifies the anisotropic behavior of ultrasonic wave transmission for materials printed with three different 3D printers. As 3D printed materials become more prevalent in manufactured products, fully characterizing the physical properties of these materials become more important. This paper examines the longitudinal velocity of sound and acoustic impedance in two directions: orthogonal and parallel to the printed layers. Each of the 3D printed materials displayed slightly different transmission results. For PMMA like samples printed on a SLA printer waves travelled more quickly in the orthogonal direction than the parallel direction. For samples printed on an industrial FDM printer using ABS the opposite was true: the parallel direction was faster than the orthogonal. For samples printed on an entry level FDM printer with PLA there was no consistent pattern, instead there was a tight clustering of ultrasonic velocity in the parallel direction but substantial variation in the orthogonal direction. Overall the variation between the orthogonal and parallel directions was found to be less than 2% in all cases.

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:
Most of desktop-scale 3D printers are based on the open-source design of the ReplicatingRapid Prototyper (REPRAP) community. One aspect that can be developed in REPRAP 3Dprinters is the addition of Internet of Things (IoT) technology. Therefore, a Raspberry Pi-based IoTsystem that can be implemented on a REPRAP 3D printer is developed. The IoT system allowsthe 3D Printer to connect into internet network and has a website-based interface. This study aimsto compare the impact of Raspberry Pi based IoT systems implementation on the 3D printingspeed and to measure productivity level of 3D printer operator. Testing is done by printing fourobjects when the IoT system has not been added to the 3D printer and printing four objects whenthe IoT system has been added to the 3D printer. In testing, the data on the printing time of eachobject is obtained, this data is used to compare the print speed between before and after the 3Dprinter was added to the IoT system. Furthermore from testing, the data of time required byoperators to prepare and monitor the performance of 3D printers is also obtained, this data is usedto compare the productivity levels of 3D printer operators before and after adding the IoT system.Based on the test results, it was found that 3D printers with IoT systems have faster printpreparation times than 3D printers without IoT systems. However, 3D printers with IoT systemshave a longer machine time than 3D printers without IoT systems. The operator productivity levelfor 3D printers with IoT systems is higher than 3D printers without IoT systems.

Abstract:
Objective: To identify 3D-printed temporal bone (TB) models that most accurately recreate cortical mastoidectomy for use as a training tool by comparison of different materials and fabrication methods. Background: There are several different printers and materials available to create 3D-printed TB models for surgical planning and trainee education. Current reports using Acrylonitrile Butadiene Styrene (ABS) plastic generated via fused deposition modeling (FDM) have validated the capacity for 3D-printed models to serve as accurate surgical simulators. Here, a head-to-head comparison of models produced using different materials and fabrication processes was performed to identify superior models for application in skull base surgical training. Methods: High-resolution CT scans of normal TBs were used to create stereolithography files with image conversion for application in 3D-printing. The 3D-printed models were constructed using five different materials and four printers, including ABS printed on a MakerBot 2x printer, photopolymerizable polymer (Photo) using the Objet 350 Connex3 Printer, polycarbonate (PC) using the FDM-Fortus 400 mc printer, and two types of photocrosslinkable acrylic resin, white and blue (FLW and FLB, respectively), using the Formlabs Form 2 stereolithography printer. Printed TBs were drilled to assess the haptic experience and recreation of TB anatomy with comparison to the current paradigm of ABS. Results: Surgical drilling demonstrated that FLW models created by FDM as well as PC and Photo models generated using photopolymerization more closely recreated cortical mastoidectomy compared to ABS models. ABS generated odor and did not represent the anatomy accurately. Blue resin performed poorly in simulation, likely due to its dark color and translucent appearance. Conclusions: PC, Photo, and FLW models best replicated surgical drilling and anatomy as compared to ABS and FLB models. These prototypes are reliable simulators for surgical training.

Abstract:
The purpose of this project was to develop a 3D printer that can print multiple durometers, or hardness, within one printed part. This project was created by Raytheon so they could develop anti-vibration housings for their electronic components that experience vibrations during flight. Team 16077 was successful in developing a printer. To achieve the result, the hardware and software of a commercial 3D printer were modified. The entire existing extrusion system was replaced with a dual extruder system with a tubing design to be able to extrude multiple filaments (a soft and a hard filament) at once. The nozzle was replaced with a mixing nozzle so that the two filaments can create a range of durometers. The firmware of the printer had to be rewritten to accept G-Code commands to run both the extruders at once at varying ratios. A standalone graphical user interface (GUI) was developed to give the user an easy way of modifying their existing G-Code file to include the mixing ratios and commands. The results show that the printer can achieve a range of durometer from 84A to 75D Shore hardness. Furthermore, the printer was successful in printing a multi-durometer part that mitigated vibrations.

Abstract:
This project is part of a bigger project where the goal is to be able to create smaller batches of individually designed pills with a high resolution. This could be done by using a powder bed 3D printer, which our job was to find out. This type of machine prints out a thin pattern of binder through a printer head and then sweeps powder over the pattern, making the powder stick to the binder. This process is repeated until the object is formed. The machine necessary was created from scratch using a guide provided by the Internet. The results were unfortunately uncertain. We managed to print with ink and the pattern created had a high level of accuracy but due to time limitations, we never got to print with actual binder in the cartridge.

Braille is a writing system that uses tactile dots in apredetermined order which, in relation to each other, representdifferent letters in the alphabet. This writing systemmakes it possible for people with visual impairmentsto take part of the written media. But the availability ofhome based braille printers is limited and these printers areoften expensive. The purpose of this project is to investigateif it is possible to build a home based braille printerfor a low cost using microcontrollers, and thereby making itmore accessible to people with visual impairment. In orderto achieve this, a prototype was built using an microcontrollertogether with stepper motors and a solenoid. Thesecomponents were then controlled by code through user inputand translated to required movements. Each switchcase then calls a set of functions that activates the steppersand the solenoid in the order needed to get the desiredcharacter. In the time frame given, the project resulted ina prototype able to print out the input it was given. Asfor the cost of building your own Braille printer in comparisonto buying one on the market highly depends on whatprocessing machines are accessible.

Abstract:
This thesis deals with color correction of a chain that starts with the 3D Artec MHT scanner, and ends with the 3D printers (CJP – Color Jet Printing technology). In principle, it is necessary to control the color interpretation of the entire chain from the scanning of real models to the 3D print model. With color properties and their color shade, including color textures. The principle of model surface scanning using a 3D scanner is in the same principle as photo camera which scans using a conventional CMOS chip. For this reason, color palettes were scanned using the photo camera and the resulting digital data were analyzed by the Darktable software. This analysis consisted of comparing the scanned color shades of the surface with the spectrofotometer measured data. The main goal of this method was to achieve color precision in the digital data during their acquirement, adjustment and interpretation. Then the same principle was applied to the data acquired by the 3D scanner to create an ICC profile of the 3D scanner. Because the 3D printer (CJP – Color Jet Printing) uses the same principle as the 2D printer, the 2D printing device calibration principle was used again to calibrate it. There have been defined procedures that adjust the color shade to the spectrophotometrically correct shades of the resulting print on a 3D printer. Color swatches were also printed for print quality verification. It has been found that with photo camera, which was used for objective measurement in the L*a*b* coordinates of independent space, any color setting and their adjustment is very sensitive to even small imprecisions. It has been found that it is not easy to obtain accurate colors within the Detla E

Abstract:
The Nordin group at Brigham Young University has been focused on developing 3D printing technology for fabrication of lab-on-a-chip (microfluidic) devices since 2013. As we showed in 2015, commercial 3D printers and resins have not been developed to meet the highly specialized needs of microfluidic device fabrication. We have therefore created custom 3D printers and resins specifically designed to meet these needs. As part of this development process, ad hoc 3D printer control software has been developed. However, the software is difficult to modify and maintain to support the numerous experimental iterations of hardware used in our custom 3D printers. This highlights the need for modular yet reliable system software that is easy to use, learn, and work with to adapt to the unique challenges of a student workforce. This thesis details the design and implementation of new 3D printer system software that meets these needs. In particular, a software engineering principle-based design approach is taken that lends itself to several specific development patterns that permit easy incorporation of new hardware into a 3D printer to enable rapid evaluation of and development with such new hardware.

Abstract:
Abstract3D printing by means of fused filament fabrication involves extruding and depositing melted material in layers to produce a 3D part. Current 3D printing requires manual intervention from a human operator between prints, leading to inefficiency. The focus of this study was facilitating the automation of the additive manufacturing process. Based on suggestions for future works in this field, this study extended on automated 3D-part removal systems by implementing additional operations to automate the production process. The proposed system uses robotic arms and grippers to operate and maintain 3D printers; specifically, the removal of 3D-printed parts, the cleaning of printer beds, the application of glue to the printer beds to assist with print adhesion, and the monitoring of bed levelness. The importance of this contribution is the improved efficiency of 3D-printing production, allowing for continuous 3D-printer operation and decreasing the requirement for human interaction and monitoring in the production process. The system is demonstrated using a 7 degrees of freedom KUKA robotic arm and ROBOTIQ gripper to autonomously operate and maintain an Ender 3 V2 printer. Sensor data and information from the 3D printers was used to determine the required operation or function to be performed by the robotic system. Tasks were performed by automated movement sequences of the robotic arm and gripper using supplied data. System status was recorded for monitoring and alerting human operators when intervention was required. The implementation of these functions using an automated robotic system allows 3D-printing production to operate continuously for longer periods, increasing production efficiency as downtime and human involvement for maintenance between prints is minimized.

Abstract:
Abstract The 3D printing technologies can produce objects with a very complex shape or geometry nowadays thanks to the advanced researches in their precision, repeatability, material ranges, etc. The size of 3D printed objects also varies. The Oak Ridge National Lab printed a 17.5 feet long, 5.5 feet wide and 1.5 feet tall tool for Boeing that weights 1,650 lbs. On the other hand, using Two Photon Polymerization, sub-μm structures can be produced. The majority of current 3D printers design resembles the traditional FDM 3D printer. The printer is stationary during the printing period, limiting the print zone by the size of the robots, regardless as to the printer designs (Cartesian, polar, delta or articulated robots). In addition, all current 3D printers work as stand-alone equipment, which prevents the possibility of further speeding up the fabrication by using multiple collaborating 3D printers. Using mobile robots as a 3D printer could eliminate the size limit of the print zone and enable collaboration among different mobile robots to speed up the printing process. However, major problems are remaining unsolved in the current mobile 3D printer research, such as the precise localization of the robot, material slipping, accumulative printing error, etc. In this paper, a vision-based feedback control system is presented as a solution to these problems in mobile 3D printers. The system is equipped a single camera as sensory input. Using Simultaneous Localization and Mapping (SLAM) methods, the mobile 3D printer could potentially achieve sub-millimeter accuracy for localization. The slipping and accumulative error could also be mediated using image processing and object recognition. The system also enables the possibility for multiple 3D printers to work simultaneously. It is believed that mobile 3D printers equipped with vision-based feedback control system could have a great potential in the future.

Abstract:
Abstract Additive manufacturing is a potentially disruptive technology with a rapidly growing market. The recent development of RepRap style 3D printers has made this technology available to the public at a low cost. While these 3D printers are being used for a variety of purposes, many mechanical engineering students use them for prototyping in their projects. The quality of the 3D printed parts has been a concern in such cases. There are many variables within the operation of these printers that can be varied to obtain optimum print quality. This study explores the use of 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 improve the cohesion between print beads, ultimately improving their mechanical properties. The objective is to understand the positional accuracy of the prints with the added vibration and then to determine the optimum level of vibration to achieve best quality prints. For the study, 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. Further, this study also explores the optimum motor speeds to achieve a uniform distribution of material and determines medium motor speeds that provide maximum amplitude of vibration which are more desirable for a uniform infill.

Abstract:
Abstract Commercially available fused deposition modeling (FDM) printers have yet to bridge the gap between printing soft, flexible materials and printing hard, rigid materials. This work presents a custom printer solution, based on open-source hardware and software, which allows a user to print both flexible and rigid polymer materials. The materials printed include NinjaFlex, SemiFlex, acrylonitrile-butadiene-styrene (ABS), Nylon, and Polycarbonate. In order to print rigid materials, a custom, high-temperature heated bed was designed to act as a print stage. Additionally, high temperature extruders were included in the design to accommodate the printing requirements of both flexible and rigid filaments. Across 25 equally spaced points on the print plate, the maximum temperature difference between any two points on the heated bed was found to be ∼9°C for a target temperature of 170°C. With a uniform temperature profile across the plate, functional prints were achieved in each material. The print quality varied, dependent on material; however, the standard deviation of layer thicknesses and size measurements of the parts were comparable to those produced on a Zortrax M200 printer. After calibration and further process development, the custom printer will be integrated into the NEXUS system — a multiscale additive manufacturing instrument with integrated 3D printing and robotic assembly (NSF Award #1828355).

Full text
Abstract:
Rapid prototyping, in particular 3-D printing, has quickly grown to be a critical part of the design, inspect, and evaluate process involved in product design. Parts of moderate size may be 3-D printed using various plastic materials like Acrylonitrile Butadiene Styrene (ABS) and nylon, which have quickly replaced the powder-based 3-D printers. These plastic processes utilize relatively inexpensive printers and materials and their popularity has soared as a result. The Purdue Polytechnic campus in Columbus, Indiana, now employs five 3-D printers to supplement its mechanical design, inspection, and validation instruction by also using the tools and resources of an environmentally-controlled metrology lab. The objective of this study is to design, print, and measure various part geometries to determine how closely the 3D printed part dimensions are to the original design. 3D printed parts do shrink as they cool following the printing process. In essence, this is very similar to shrinkage that occurs during the metal casting process and so the goal is identify and create a "shrink rule" for 3D printed plastic parts. There are multiple variables involved in the process including material, nozzle speed of the 3D printer, resolution of the printer, and size of the part among others. These different variables are explored in this study to determine the optimal process for accurate and repeatable 3D printing. A Zeiss Duramax coordinate measuring machine is utilized to perform the dimensional measurements of the parts. Various part orientations on the CMM are also investigated to determine any sensitivity to the measurement process. Results will demonstrate that parts need to be scaled up by 1.1% to 1.3% to accurately account for shrinkage of the material.

Abstract:
An entry level consumer priced 3d-printer, the MakerBot Replicator 2x, was used to print specimen to conduct tensile, flexural and fatigue testing. Average priced, generic brand PLA material was used (similar to the filament a home user may purchase). Specimen were printed at raster orientation angles of 0°, 45° and 90° to test orientation effects on part strength. PLA filament was also tensile tested. Tensile testing of the 3d-printed specimens showed that the 45° raster orientation angle made the strongest specimen at an ultimate tensile strength of 64 MPa. The 0° and 90° raster orientation were not much less at 58 MPa and 54 MPa. A 3-point bending fixture was used to conduct flexural testing on printed specimen. For this type of testing, the 0° raster orientation produced the strongest parts with an ultimate bending stress of 102 MPa. Both the 45° and 90° raster orientations had similar results at 90 MPa and 86 MPa. For the fatigue testing, there was no clear best option, but there was a clearly worst option, the 90° raster orientation. This orientation clearly had lower fatigue lives than either of the other two raster orientations. The other two raster orientations, 0° and 45°, were very similar. PLA filament testing using bollard style grips, showed that the PLA filament exhibited mechanical properties similar to that of printed specimen — when tested at high enough strain rates that creep damage didn’t play a significant role. This may lead to implications for recycling failed 3d-print jobs and turning it back into reusable filament.

Abstract:
Digital Light Processing (DLP) 3D printing allows for the creation of parts with advanced engineering materials and geometries difficult to produce through conventional manufacturing techniques. Photosensitive resin monomers are activated with a UV-producing LCD screen to polymerize, layer by layer, forming the desired part. With the right mixture of photosensitive resin and advanced engineering powder material, useful engineering-grade parts can be produced. The Bison 1000 is a research-grade DLP printer that permits the user to change many parameters, in order to discover an optimal method for producing 3D parts of any material of interest. In this presentation, the process parameter optimization and their influence on the 3D printed parts through DLP technique will be discussed. The presentation is focused on developing 3D printable slurry, printing of complex ceramic lattice structures, as well as post heat treatment of these DLP-produced parts.

Abstract:
In additive construction, ambitious goals to fabricate a concrete building in less than 24 hours are attempted. In the field, this goal relies on a metric of print time to make this conclusion, which excludes rest time and delays. The task to complete a building in 24 hours was put to the test with the first attempt at a fully continuous print of a structurally reinforced additively constructed concrete (ACC) building. A time series analysis was performed during the construction of a 512 ft2 (16’x32’x9.25’) building to explore the effect of delays on the completion time. This analysis included a study of the variation in comprehensive layer print times, expected trends and forecasting for what is expected in future prints of similar types. Furthermore, the study included a determination and comparison of print time, elapsed time, and construction time, as well as a look at the effect of environmental conditions on the delay events. Upon finishing, the analysis concluded that the 3D-printed building was completed in 14-hours of print time, 31.2- hours elapsed time, a total of 5 days of construction time. This emphasizes that reports on newly 3D-printed constructions need to provide a definition of time that includes all possible duration periods to communicate realistic capabilities of this new technology.

Full text
Abstract:
An oft-cited benefit of additive manufacturing (AM), or “3D-printing,” technology is the ability to produce parts at the point of use by downloading a digital file and making the part at a local printer. This has the potential to greatly compress supply chains, lead times, inventories, and design iterations for custom parts. As a result of this, both manufacturing and logistics companies are investigating and investing in AM capacity for production at the point of use. However, it can be imagined that the feasibility and benefits are a function of size, materials, build time, manufacturing complexity, cost, and competing technologies. Because of this, there are instances where the viability of point-of-use manufacturing ranges from the perfect solution to the worst possible choice. Unsettled Topics on the Benefits of Additive Manufacturing for Production at the Point of Use in the Mobility Industry discusses the benefits, challenges, trade-offs, and other determining factors regarding this new level of AM possibilities.
