is capable of producing the required product directly and automatically from a 3D computer
model representation, have been selected to build implant and scaffold structures using composite
materials consisting of a polymer and a bioactive ceramic. Hydroxyapatite (HA), a bioceramic
that encourages bone apposition, can be combined with high density polyethylene
(HDPE), a biocompatible polymer, to form a material with appropriate stiffness, toughness and
bioactivity for use in the body. A miniature SLS system was built to minimize the usage of the
expensive experimental material. It was used to determine the CO2 laser sintering operation
window of the HA/HDPE composites and to investigate the effect of the process parameters on
the surface morphology of the sintered HA/HDPE layer. The potential of SLS for the rapid
manufacture of customised implants using HA/HDPE composite is demonstrated by the sintering
of a 5-layer HA-HDPE block.
