3D Printed Devices and Biocompatibility: Material Aeration

The previous three posts addressed biocompatibility concerns of 3D printed devices considering additives to the raw materials, the material curing process, and post-printing finishing processes. Both thermoplastics and photopolymers contain additives (oligomers, plasticizers, preservatives, etc.) that are freshly redistributed through...
