SLA for Medical Applications

Although SLA samples are generally regarded as not biologically compatible, DSM has successfully tested 2 of their resins to USP IV.

Somos® WaterShed XC 11122 resin – a clear, durable, water resistant material – has been tested and approved for USP Class VI in biomedical and skin contact applications.

DSM reports that the ABS-like material passed  ISO 10993-5 Cytotoxicity, ISO 10993-10 Sensitization, ISO 10993-10 Irritation certified and was USP Class VI approved.   Reading ISO 10993-1 that would make it good enough for Surface Devices: Skin Contact.   Likewise that gets it most of the way there for other applications too.

The other resin is for high temperature applications and is Somos ProtoTherm™ 12100 Series.
