Development of a Novel Methodology to Overcome Support Issues in Selective Laser Melting
This project aimed to develop a soft support system that can be removed by means of sandblasting, instead of using tools such as a chisel or a hammer in areas with little or no access. At locations where the part features large cross-sectional areas such as the one shown in the picture, the hard support system will be applied. In easy access areas, hard or soft supports may be applied, depending on the part feature. In essence, this hybrid system of hard and soft supports can be applied to manufacture a part successfully, without any design constraints. The development of this solution reflects the true advantage of the metal powder bed fusion technology, ie., design freedom.
Development of Additive Manufacture Plan for Dental Prosthesis
The objective of this project is to reduce manual operations in dental lab manufacturing. The above pictures demonstrate the product of cobalt chrome coping and porcelain fused to CoCr dental crowns manufactured using 3D printing technology.
A low cost method for zirconia dental crown fabrication- Electrophoretic deposition (EPD)
This project aimed to reduce the cost of zirconia all-ceramic dental crowns or bridges manufactured using Electrophoretic Deposition (EPD). The above pictures demonstrate the mechanism of EPD, the green part by EPD, the product of zirconia all-ceramic dental crown products after sintering. Their shapes are defined with the aid of 3D printing technology.
Binder Jet 3D Printing of Removable Partial Denture Cobalt Chrome Frame
The primary objective of the project is to print dental products, especial metal frames, with minimal post process. The above pictures demonstrate the Binder Jet 3D Printer, the dental plaster models and the removable partial denture.
3D Dental Crown
A new method of fabricating 3D dental crowns, invented by researchers at the DFAMC in collaboration with the Temasek Microelectronics Centre and industry partner Prextron Pte Ltd, was featured in The Straits Times (30 Dec 2017) and LianHe ZaoBao (30 Dec 2017), as well as The New Paper (5 Jan 2018).
