Rapid Prototyping (RP) is a manufacturing process that produces a 3D model CAD to be a real product rapidly by using additive manufacturing technology. In this case, the product will print layer by layer uses a 3D printer machine. The 3D printer requires slicer software to convert CAD data into data that a 3D printer machine can read. Research is done to analyze the effect of three kinds of slicer software on 3D printing objects on the accuracy and surface roughness of the product. The 3D model CAD is sliced using three different slicer software, namely Ideamaker, Repetier Host, and Cura. The slice model result from each slicer will be printed on a 3D printer machine with the same process parameters to be compared. Then the product's dimensional and surface roughness will be measured to determine the effect of each slicer on product quality. The best quality of the product reflected the most suitable slicer software for the 3D printing machine that used. The best results achieved by Cura slicer because it has resulted in small dimensional deviations (max 0,0308±0,0079) and stabile high surface roughness of the product (max 1,585+059).

Baking Process

Purpose The purpose of this paper is to present three-dimensional (3D) printing of structures with a new method called selective laser baking (SLB) of Poly Dimethyl Siloxane (PDMS). Design/methodology/approach A 3D model is designed on the computer. PDMS Base is mixed with its hardener and poured into a container. Before it is hardened which normally occures after several hours, a CO2 laser selectively exposes different areas on the surface of the PDMS mixture according to the pattern of a slice of a 3D model designed on the computer. Because of the thermal effect of the CO2 laser, once exposed, PDMS heats up and hardens, producing a cured layer of PDMS which is attached to a base. The base with the cured layer is lowered in the container for a short distance and a layer of new uncured PDMS is spread over the previous layer. The laser exposes new areas again and hardens them. This process is repeated until the whole structure is fabricated. Findings The parameters involved in the baking process are investigated and the relation between temperature, mixing portion and laser irradiance on the curing time and layer thickness are investigated. Originality/value This fabrication technique is a unique fabrication method that helps to 3D print with two base polymers which their polymerization can be boosted by heat. This 3D printing method has not been presented earlier.

This study aims to invent a new, low-cost, and faster method of prosthetic socket fabrication, especially in Indonesia. In this paper, the photogrammetry with the 3D printing method is introduced as the new applicative way for transradial prosthetic making. Photogrammetry is used to retrieve a 3D model of the amputated hand stump using a digital camera. A digital camera is used for photogrammetry technique and the resulting 3D model is printed using a circular 3D printer with Polylactic acid (PLA) material. The conventional casting socket fabrication method was also conducted in this study as a comparison. Both prosthetic sockets were analyzed for usability, and sectional area conformities to determine the size deviation using the image processing method. This study concludes that the manufacturing of transradial prosthetic sockets incorporating the photogrammetry technique reduces the total man-hour production. Based on the results, it can be implied that the photogrammetry technique is a more efficient and economical method compared to the conventional casting method. The 3D printed socket resulting from the photogrammetry method has a 5–19% area deviation to the casting socket but it is still preferable and adjustable for the transradial amputee when applied to the stump of the remaining hand.

This paper presents design and development of a viewing and editing tool, namely 3DPJ Editor, for Workflow visualization of 3D Print Job files. 3D Print Job (3DPJ) is an XML based format for 3D Printing job purposed to enable automation and integration of multiple vendor systems in a 3D Printing manufacture environment. The paper also shows preliminary 3DPJ format for further development of 3D Printing manufacture community with multiple vendors. The 3DPJ Format tries to separate content information and meta-data of 3D Print Jobs, in order to integrate different processes into one standard 3D Printing Workflow. The complete specification of 3DPJ should be further complex and comprehensive, and it should be gradually adopted by major 3D Printer vendors.

Background: Cranioplasty is a neurosurgical procedure to repair skull defects. Sometimes, the patients’ bone flap cannot be used for various reasons. Alternatives include a custom polyether ether ketone (PEEK) implant or titanium mesh; both incur an additional cost. We present a technique that uses a 3D printer to create a patient- specific 3D model used to mold a titanium mesh preoperatively. Case Description: We included three patients whose bone flap could not be used. We collected the patients’ demographics, cost, and time data for implants and the 3D printer. The patients’ computed tomography DICOM images were used for 3D reconstruction of the cranial defect. A 3D printer (Flashforge, CA) was used to print a custom mold of the defect, which was used to shape the titanium mesh. All patients had excellent cosmetic results with no complications. The time required to print a 3D model was ~ 6 h and 45 min for preoperative shaping of the titanium implant. The intraoperative molding (IOM) of a titanium mesh needed an average of 60 min additional operative room time which incurred $4000. The average cost for PEEK and flat titanium mesh is $12,600 and $6750. Our method resulted in $4000 and $5500 cost reduction in comparison to flat mesh with IOM and PEEK implant. Conclusion: 3D printing technology can create a custom model to shape a titanium mesh preoperatively for cranioplasty. It can result in excellent cosmetic results and significant cost reduction in comparison to other cranioplasty options.

In orthopedics, 3D printing is a novel way of visualizing dense human tissue and structures, for example bones and ligaments, but also the respective relations between them, thus providing the surgical team with taking the preoperative planning of an intervention one step further from 3D computer reconstructions. In order for a medical 3D print reconstruction to be possible, bidimensional imaging is necessary, in the form of DICOM files. These are then used by specific software in order to create an STL file, that can then be inputted into a 3D printer and a three-dimensional replica of the desired structure, usually on a 1:1 scale, can be generated. We aim to compare two methods of acquiring and processing of 2D images � MRI and CT scans � as sources of DICOM files, with the end purpose of 3D printing the image of human bone.

The growth of 3D printing has been rapid over the decades. Laika is a United States-based animation production company, and the pioneer of 3D printing technology in stop-motion animation. Laika uses this technology in their production pipeline for making stop-motion puppets in most of their films, including their latest films, Kubo and the Two Strings (2016). Due to limited access and information of details of Laika’s facial expression, communities and fans of animation have tried to conduct experiments with their own 3D print, using footages of behind-the-screen processes from Laika studio. This paper explores facial expressions for creating stop-motion puppet using an affordable home scale 3D printer. Using limited technical information collected from documentation video from Laika as well as referring to articles written by stop-motion enthusiasts, this fan-based research ignites creativity to overcome the barriers of technology and access through strategies in producing affordable 3D print stop-motion animation. Keywords: Stop-motion animation, 3D printing, facial expressions.

Abstract. The results of experimental studies of the efficiency of manufacturing polymer foundry models by the FDM method are presented. Rational consumables for 3D-printing are revealed. The optimal values of the shrinkage value of the 3D-model during printing and the parameters of the 3D-printer operation mode are revealed. It has been established that polymer casting molds are rationally manufactured by FDM printing, using ABS-plastic as a consumable, while making a correction to linear dimensions at the stage of creating a 3D-model to eliminate plastic shrinkage.
