Abstract
It is widely recognized that layered manufacturing techniques have the potential to make an important contribution in medicine. One of the most exciting areas of their application is the production of the bone-interfacing implants currently used in orthopaedics and dentistry. This article studies the laser sintering of a mixture of Calcium Polyphosphate (CPP) and Polyvinyl Alcohol (PVA) to make structures with possible applications in such areas. An experimental study of the creation of the green part is performed to identify the effects of different process parameters such as laser power and scanning speed. The work indicated that the CPP-PVA sintered layer thickness can be adjusted by controlling the laser sintering process parameters. The fabricated samples can be either utilized as composite bio-structures or considered as green parts for post-densification through conventional sintering.
