thereafter, be bonded to each other to form the complete dentures. The 3D manufacturing through additive rapid prototyping comprises of a layering process. Commercially available prototyping machines include: steriolithography apparatus (SLA), selective laser sintering (SLS), laminated object manufacturing (LOM), multi-jet modeling (MJM) and fused deposition modeling (FDM) (11). Safety for intra-oral use of most of the currently available rapid prototyping materials remains a concern. In 2012, Inokoshi

Title The Development and Challenge of 3D Printing Introduction In recent years 3D printing arouses focus of public with appearing in a huge number of areas. In this essay, it will describe 3D printing which is one important application of rapid prototyping. Rapid prototyping (RP) is general for several techniques, which read in data from computer-aided design (CAD) drawings and manufacture automatically three-dimensional objects layer-by-layer according to the virtual design (Sanna 2008). 3D

TECHNOLOGY Materials for 3D printing were very limited during the early days of the technology. Today, there is a whole array of material types that are supplied in different forms (filament, powder, pellets, resin, granules etc). The first step in 3D printing is to design the 3D digital model using a CAD program or scan the object with a 3D scanner. The model will then be ‘sliced’ into layers and converted into a printer-readable file. The printing material will be added one layer at a time.

The thousands upon thousands of amorphous thermoplastics in existence provide many options as to what properties a printed object can have. Both ABS and PLA are commonly used plastic 3-D filament, but they are used for very different reasons. ABS has a higher melting temperature and printing temperature than PLA probably due to the extra entanglement cause by the branching chains in ABS. Without a properly heated printing bed, this could cause warping and shrinkage of the ABS object when lower layers

predetermined shape. Because parts can be printed directly, it is possible to produce very detailed and intricate objects. As well as technology, there are multiple processes for 3D printing. The very first being Stereolithography (SL). SL is a very accurate laser-based process that works with photopolymer resins (see picture one). Next is Digital Light Processing (DLP), which is similar to SL in the aspect of photopolymers. The only major difference/advantage between the two is that DLP only

printers use STL files in addition to some proprietary file types such as, ZPR by Z corporation. Some of the types of printers include, Sterolithography or (SLA), Digital Light Processing (DLP), Fused deposition modeling (FDM), Selective Laser Sintering (SLS), Selective laser melting (SLM), Electronic Beam Melting (EBM), and Lamainatied

INTRODUCTION Additive manufacturing has been developing since 19841. Charles hull invented it. In additive manufacturing 3 dimensional products are built by staking materials layer by layer. It is also known as 3D printing. The scope of technology is sky rocketed with the intervention of the fourth-dimension time, which is 4D printing technology. The interesting feature of 4D printing is it can transform from 1D to 3D shape, 1D surface to 3D shape, or can morph from 3D form to

This may act as a barrier to small and medium sized entrepreneurs. There are several compliances that are required from the industries such as under employment laws, the company many not be able prevent other companies from benefiting from some of their former employees; failure to comply with U.S. Foreign Corrupt Practices

Problem Statement Last summer, I started an internship with Shriners Hospital for Children in their Motion Analysis Lab. During my internship there, I realized that many children could not afford to wait the three months necessary for standard ankle braces. In addition, many poorer families struggle to afford such expensive devices. My goal for this invention is to develop a feasible and medically accepted system in which a 3D scan of the patient’s foot will be manipulated on the computer to create
