Investigating the influence of heat treatment in a pressurised atmosphere on the ductility of SLS-printed PA12

In the last decade, Selective Laser Sintering (SLS) of Polyamide 12 (PA12) has evolved into a production method for end-use components. To adopt SLS-PA12 in demanding applications such as machine parts and orthopaedics, high ductility is required for safety and long service life. Whilst SLS-printed PA12 has high strength, the material is porous and brittle compared to injection moulded PA12. Attention turned to post-processing, primarily heat treatment in an isostatically pressurised atmosphere. Experiments were performed to gain insight into the influence of heat treatment in a pressurised atmosphere on the part density and mechanical properties of SLS-printed PA12.
