Issues surrounding the materials used within 3D-printing are not a new phenomenon: Sun indicates that raw materials, such as poly-lactic acid are neither comfortable nor flexible enough for fashion garments. Similarly, in an interview with Wired’s Bradley Rothenberg, co-designer on the threeASFOUR project, it is highlighted that “with The scope of 3D bioprinting includes not only the issues of the advanced technologies of human tissues and organs printing but also raises a whole layer of interdisciplinary problems of modern science, technology, bioethics, and philosophy. This article addresses the ethical and legal issues of bioprinting of artificial human organs. Ethics of 3D printed Firearms, An Overview. "Ghost Gunner 3D Printer: Legally Make Your Own Rifle At Home: “No Serial Number, No Background Check, And No Waiting Period”. Maintaining control over the industrial manufacturing of 3D printed firearms by introducing regulations in the manufacturing process where crucial components of these guns Due to their disruptive nature and potential, 3D printing and even more 3D bioprinting raise many ethical and safety concerns that need to be adequately addressed to provide good regulation before entering clinical practice. This article aims to highlight the general ethical concerns associated with the use of additive manufacturing in medicine Binding/Fusing. Most Prominent Potential Hazards. Material extrusion. Thermoplastics (may include additives) Spooled filament, pellet, or granulate. Electrical heating element-induced melting/cooling. Inhalation exposure to VOCs, particulate, additives; burns. Powder bed fusion. Metal, ceramic, or plastic. a10A. Even hearts. The FDA has approved skull caps that could repair cranial damage—one patient had 75% of his skull repaired using these 3D-printed materials. And this isn’t just science fiction In this instance, 3D printing allowed manipulation of the surface (i.e., denticle distribution and flexibility of the “skin”) and removed ethical issues of using real skin. Wen et al.'s ( 2014 ) findings were echoed by Lauder et al. ( 2016 ), who also demonstrated the ability of 3D printing to accurately produce objects which are Ethics of Using 3D Printing Technology to Reconstruct Heritage ROSHNI KHUNTI,University of Cambridge, United Kingdom The use of 3D printing technology to reconstruct the Arch of Triumph in Palmyra has opened a Pandora’s Box of ethical issues relating to the use of digital technology to preserve heritage represented by historical objects and IntroductionStudies on computed tomography (CT) reproducibility at different acquisition parameters have to take into account radiation dose administered and related ethical issues. 3D-printed phantoms provide the possibility to investigate these features deeply and to foster CT research, also taking advantage by outperforming new generation scanners. The aim of this study is to propose a new 3D printing doesn’t per se pose a threat to privacy (although we have heard [unsubstantiated] rumours of printers passing information about prints back to manufacturers). The issue we have
