Kata kunci : 3D Modelling, 3D Printing, Desain Industri, Desain 3D   Abstract Industrial design education requires stages according the timeline of the era. The learning needed must be in accordance with the demands of the era, ie technological advancements that function to facilitate aspects of the use and manufacture in the field of industrial design. Industrial design has basic stages, ie ideas, concepts, sketch drawings, three dimensional projections, scale modeling and mockups or prototypes. In each of these stages, developments that have a large influence are the stages of three dimensional projection. The 3-dimensional projection is not just making a model and creating a rendering result, but it has turned to the real results of entering the 3D mockup / 3D prototype through 3D Printer which is called 3D Printing. The importance of education such as Universities, Colleges, Academies and course places that have this subject of study, must include 3D Printing education into the subject of learning / 3D Modeling (CAD / CAID) courses. Entering the fourth industrial revolution era certainly requires some updates on each subject of learning in industrial design education, this is because it is related to technological elements in the world of industrial design ie 3D Printing machine. At present, jobs are urgently needed that require 3D Printer machine operators to emerge from graduates of product design / industrial design. Approved operators are those who understand 3D Modeling software. These graduates must be knowledgeable in the operation of 3D Printer machines that are closely related to CAD / CAID in diploma or bachelor degree.

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).

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.

The article provides an analysis of modern and affordable software systems for modelling shells of complex geometry and the possibilities of using these software systems in 3D printing. Such an analysis made it possible to choose software systems that most accurately allow for the implementation of the 3D modeling method proposed in the article with subsequent printing on a 3D printer. This method is considered in detail on the example of constructing several types of helicoids. The process of 3D modeling of a helicoid is described step by step and is divided into several stages: parametric modeling of a helicoid in SCAD, editing of the resulting model in AutoCAD and its export to a special format for 3D printing. The use of the method of parametric modeling is due to its accuracy and uncompromisingness. With its help, one can accurately judge the type of the built surface. Parametric modeling is the construction of a surface by compiling equations on each axis, i.e. along the x, y, z axes, and for each type of surface there are specific characteristic equations. It is not possible to implement the method of parametric modeling in all software systems; in this connection, certain difficulties arise. The article analyzes the difficulties encountered in 3D modeling of the helicoid and suggests ways to solve them.

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.

Great Possibility

3D printing as additive manufacturing enables to give concept proposers and designers a great possibility of producing physical parts and concept models at acceptable cost during a short time. Such technology is quite distinct from traditional machining techniques adopting subtractive process. The purpose of this study is to briefly describe new micro-scale manufacture utilizing a series of process of 3D printing, including 3D modeling, 3D model slicing, printing, and products. Especially, 3D modeling is one of major components in 3D printing process and becomes a barrier to entry the business of micro-scale manufacture for everyone with a 3-D printer. This paper introduces two low-cost approaches to generate 3D models, including active and passive approaches. 3D scanning as an active approach allows the replication of real objects without the need of moulding techniques. On the other hand, image-based modeling as a passive is an alternative of un-touch model reconstruction without a threat of destructive impact to the modeled object. Also, a statue in gypsum was made by a 3D printer based on a digital 3D model generated through the low-cost active approach for demonstration.
