Post-processing Considerations for Biomedical 3D Printing of Polymers
In the last 10 years, additive manufacturing has progressed from being not just a prototyping technology but a manufacturing technology within the medical manufacturing industry; it has turned many medical manufacturing sectors completely on their heads such as the dental and hearing aid device making industries. 3D printing can create models of high organic intricacy in a relatively short period of time. It has greatly added to the medical industry advancements in visualising and creating complex human or animal anatomies and can be used as an aid for surgical planning and preparation, physician and patient pre-operative/treatment education, medical procedure training and upskilling, medical devices, medical device development, and custom medical device manufacturing. Additive manufacturing (AM) is rapidly growing with advances in new material development, higher resolution, and faster speeds, making it a cost-effective alternative manufacturing solution for many medical applications. The objective of this chapter is to provide some guidelines and considerations of the many steps involved in the manufacturing of biomedical polymers and the main post-processing considerations for individual types of industrial polymer technologies.
