This paper addresses the topic of whether, and to what extent, copyrights should govern the distribution of 3D printing plans which are used in creating 3D printed, tangible objects. The essay discusses the various 3D printing technologies, describes how 3D printing is accomplished, defines copyright, and then briefly outlines the Digital Millennium Copyright Act (“DMCA”) of 1998. In particular, the paper lists the conditions that a firm publishing 3D printing plans must satisfy to invoke Section 512(c) safe harbor provision of the DMCA. Finally, the essay discusses when a distributor of 3D printing plans would be protected under the safe harbor provisions, arguing that when a 3D printing plan is released not-for-profit, the organization is protected under Section 512(c).

Open bite malocclusion, due to it’s multifactorial etiology, has always been considered a difficult problem to treat. Often associated with transverse maxillary deficiency, this is a real challenge in the field of orthodontics. The traditional approach, for this type of anomaly, in adult patients, is orthognathic surgery and RME (rapid maxillary expansion). There are several approaches to the treatment of adult patients using digital technology. Mini-implant supported palatal expander limits the side effects of the conventional RME and is less invasive compared to orthognathic surgery. Precise and predictable mini-implant insertion, using a customized surgical guide, provides a safe therapeutic approach. This case report combines Cone-beam computed tomography (CBCT), laser scan superimposition, computer-aided design (CAD) and 3D printing in order to design and print a customized surgical guide for orthodontic mini-implant insertion. A CBCT scan was performed to determine the optimal site for mini-implants’ placement. Using the 3Shape Trios Intraoral Scanner the maxilla and the mandible were laser-scanned. Blue Sky Plan 4 software was used to design the surgical guide, and RayWare software was used for printing it. 4 mini-implants were inserted using a safe and predictable technique. The 3D technology represents the future of orthodontics, reducing the risks, chair-side time while providing the best treatment plan for the patient.

Bone Scaffold is a three-dimensional porous construction which provides support to promote natural cell growth in damaged or broken section of bone. In recent years researchers from various departments like biomedical, mechanical, orthopedics, have shown significant interest in adopting ‘Bone Scaffolds’ as a promising treatment for bone defects. ‘Bone Scaffold’ is a honeycomb-like architecture composes of bio-compatible material having grater advantages over current grafting solution. In this paper, the authors try to review the available e-articles in an organized way on the bone scaffold in the field of biomedical implants with 3D printing. The selected literature mainly focuses on the biocompatible material and various advanced manufacturing methods used for manufacturing / preparing of bone scaffolds. This article tries to padding the gap between theoretical and actual implementation of ‘Bone Scaffolds’ by properly analyzing selected research and allowing future opportunities for reinventing the new possibilities in the field of biomedical.
