Although three-dimensional (3D)-printed anatomic models are not new to medicine, the high costs and lengthy production times entailed have limited their application. Our goal was developing a new and less costly 3D modeling method to depict organ-tumor relations at faster printing speeds. We have devised a method of 3D modeling using tomographic images. Coordinates are extracted at a specified interval, connecting them to create mesh-work replicas. Adjacent constructs are depicted by density variations, showing anatomic targets (i.e., tumors) in contrasting colors. An array of organ solid-tumor models was printed via a Fused Deposition Modeling 3D printer at significantly less cost ($0.05/cm3) and time expenditure (1.73 min/cm3; both, p < 0.001). Printed models helped promote visual appreciation of organ-tumor anatomy and adjacent tissues. Our mesh-work 3D thyroidal prototype reproduced glandular size/contour and tumor location, readily approximating the surgical specimen. This newly devised mesh-type 3D printing method may facilitate anatomic modeling for personalized care and improve patient awareness during informed surgical consent.

Three-dimensional (3D) printing is opening new opportunities in biomedicine by enabling creative problem solving, faster prototyping of ideas, advances in tissue engineering, and customized patient solutions. The National Institutes of Health (NIH) Library purchased a Makerbot Replicator 2 3D printer to give scientists a chance to try out this technology. To launch the service, the library offered training, conducted a survey on service model preferences, and tracked usage and class attendance. 3D printing was very popular, with new lab equipment prototypes being the most common model type. Most survey respondents indicated they would use the service again and be willing to pay for models. There was high interest in training for 3D modeling, which has a steep learning curve. 3D printers also require significant care and repairs. NIH scientists are using 3D printing to improve their research, and it is opening new avenues for problem solving in labs. Several scientists found the 3D printer so helpful they bought one for their labs. Having a printer in a central and open location like a library can help scientists, doctors, and students learn how to use this technology in their work.

As an additive manufacturing process, 3D printing provides conceptualizers and designers an opportunity to quickly produce physical components and concept models at reasonable costs. Such manufacturing is distinct from mass production involving traditional subtractive machining processes. This paper briefly describes microscale manufacturing involving a series of 3D-printing-related processes, including 3D modeling, 3D model slicing, printing, and production. Furthermore, specifications of 3D printers, a major component of the 3D printing process, impedes the entry of new micro-manufacturing businesses, such as the maximum printing volume, printing material, positioning accuracy, layer thickness, and price, were analyzed. In addition, online 3D printing service could be an alternative to overcome the difficulty of new entry to micro-manufacturing by a step-by-step instruction through internet. Commercially available online 3D printing services were surveyed and compared in material and cost in this paper.

Abstrak Pendidikan desain industri memerlukan tahapan-tahapan sesuai pada zamannya. Pembelajaran yang dibutuhkan harus sesuai tuntutan zaman yakni kemajuan teknologi yang berfungsi memudahkan dalam aspek penggunaan dan pembuatan dalam bidang desain industri. Desain industri memiliki tahapan dasar, yaitu ide, konsep, gambar sketsa, proyeksi tiga dimensi, pemodelan skala dan mockup atau prototipe. Dalam tiap tahapan tersebut, perkembangan yang mempunyai pengaruh besar adalah tahapan proyeksi tiga dimensi. Proyeksi tiga dimensi tidak hanya sekedar membuat model dan menciptakan hasil render, tapi sudah pada kepada hasil nyatanya yaitu masuk ke ranah 3D mockup/3D prototipe melalui 3D Printer yang disebut sebagai 3D Printing. Pentingnya pendidikan seperti Universitas, Sekolah Tinggi, Akademi maupun tempat-tempat kursus yang memiliki mata pembelajaran ini, wajib menyertakan pendidikan 3D Printing ke dalam mata pembelajaran/mata kuliah 3D Modelling (CAD/CAID). Memasuki era Revolusi Industri Keempat tentu memerlukan beberapa update pada masing-masing mata pembelajaran pada pendidikan desain industri, hal ini karena berkaitan dengan unsur teknologi dalam dunia desain industri yaitu mesin Printer 3D. Saat ini, sangat dibutuhkan lapangan pekerjaan yang membutuhkan operator mesin 3D Printer yang muncul dari lulusan-lulusan desain produk/desain industri. Operator yang dimaksud adalah lulusan yang menguasai software 3D Modelling. Lulusan tersebut harus dibubuhi ilmu dalam pengoperasian mesin 3D Printer yang berkaitan erat dengan CAD/CAID dalam diploma maupun Strata Satu. Sehingga dapat menciptakan lulusan yang berkompeten dan menjadi pekerja yang sangat dibutuhkan di perusahaan yang mengaplikasikan teknologi-teknologi Revolusi Industri Keempat. 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. So that it can create competent graduates who are needed workers in companies that apply fourth industrial revolution technologies.

Background: Three-dimensional (3D) printing is a computer-directed process leading to the layered synthesis of scaled models. The popularity and availability of the technique has exponentially increased over the last decade, and as such is seeing a greater number of medical and surgical applications. Methods: We report 3 cases involving the use of 3D printing as an aid to operative planning in the revision of wrist surgery. Results: All patients underwent successful operative interventions with a £34 average cost of model creation. Conclusions: A growing number of reports are emerging in reconstructive surgical specialities including maxillofacial, orthopedic, and plastic surgery; from our experience, we advocate the economically viable use of 3D printing for preoperative templating.
