VISUALIZATION OF SPECIAL VEHICLE DUMMY BODY PARTS WITH THREE DIMENSIONAL PRINTER TECHNIQUES

PT. Pindad Persero is a military manufacturing industry specialized vehicle division that uses three-dimensional printer techniques, in each design to accelerate the form of a prototype product development. A three dimensional printer is a new breakthrough in the world of technology, a printer that is capable of printing three-dimensional objects, not in the form of images or writing on a paper but rather a tangible form that has dimensions both real dimensions and scale of comparison. The advantages of three-dimensional printers, it is possible to make complex shapes. This is due to the flexibility of printing movements in the three-dimensional scope. Related to this, in every opportunity to promote a product, of course the role of three dimensional printers is very important, as a display tool or technique in promoting a three dimensional printer product process, so that this role can accelerate the process of duplicating forms or the realization of forms with temporary material or dummy, this technique is quite effective and reduces production costs, and the results of the form 99% resemble the real form, refining the shape of the dummy body parts of combat vehicles, of course there needs to be special techniques so that the results are perfect as in real forms, both in form and technique finishing paint finishing.

3D Printing Provides a Precise Approach in the Treatment of Tetralogy of Fallot, Pulmonary Atresia with Major Aortopulmonary Collateral Arteries.

Patients with tetralogy of Fallot, pulmonary atresia, and multiple aortopulmonary collateral arteries (Tet PA MAPCAs) have a wide spectrum of anatomy and disease severity. Management of these patients can be challenging and often require multiple high-risk surgical and interventional catheterization procedures. These interventions are made challenging by complex anatomy that require the proceduralist to mentally reconstruct three-dimensional anatomic relationships from two-dimensional images. Three-dimensional (3D) printing is an emerging medical technology that provides added benefits in the management of patients with Tet PA MAPCAs. When used in combination with current diagnostic modalities and procedures, 3D printing provides a precise approach to the management of these challenging, high-risk patients. Specifically, 3D printing enables detailed surgical and interventional planning prior to the procedure, which may improve procedural outcomes, decrease complications, and reduce procedure-related radiation dose and contrast load

Advanced Ceramic Materials and Processes for Three-Dimensional Printing (3DP)

The University of Washington and ExOne, Inc. are collaborating in the development of advanced ceramic materials and processes for three-dimensional printing (3DP). The focus of the research to be presented is work funded by the National Science Foundation to develop a biocompatible alumina-based system for medical and dental applications. Materials design, characterization, and processing considerations will be discussed.Mechanical Engineerin

3D-printing techniques in a medical setting : a systematic literature review

Background: Three-dimensional (3D) printing has numerous applications and has gained much interest in the medical world. The constantly improving quality of 3D-printing applications has contributed to their increased use on patients. This paper summarizes the literature on surgical 3D-printing applications used on patients, with a focus on reported clinical and economic outcomes. Methods: Three major literature databases were screened for case series (more than three cases described in the same study) and trials of surgical applications of 3D printing in humans. Results: 227 surgical papers were analyzed and summarized using an evidence table. The papers described the use of 3D printing for surgical guides, anatomical models, and custom implants. 3D printing is used in multiple surgical domains, such as orthopedics, maxillofacial surgery, cranial surgery, and spinal surgery. In general, the advantages of 3D-printed parts are said to include reduced surgical time, improved medical outcome, and decreased radiation exposure. The costs of printing and additional scans generally increase the overall cost of the procedure. Conclusion: 3D printing is well integrated in surgical practice and research. Applications vary from anatomical models mainly intended for surgical planning to surgical guides and implants. Our research suggests that there are several advantages to 3D- printed applications, but that further research is needed to determine whether the increased intervention costs can be balanced with the observable advantages of this new technology. There is a need for a formal cost-effectiveness analysis
