First stereolithography resins to meet ISO 10993-5 and ISO 10993-10 medical standards

DSM Somos announced that two of its materials, WaterShed XC 11122 and ProtoGen 18420, have become the only currently available SL resins to meet ISO 10933 standards for use in medical device applications. The announcement came after Watershed XC 11122, a clear, water-resistant SL resin and ProtoGen 18420, a white, ABS-like general purpose resin, received ISO 10993-5 cytotoxicity, ISO 10993-10 sensitisation and ISO 10993-10 irritation certifications.

In the 5,000+ companies throughout the world that currently develop medical devices, success is all about speed – that is, the speed in which new and improved devices can be tried, tested, and introduced to the market. Using traditional prototyping methods that most medical device companies are currently familiar with, it can take several weeks or even months to create a new prototype.

By using stereolithography (SL) as a prototyping technology, it is possible to develop a functional prototype in a few days vs. 1–2months with conventional methods. Both products can now be recommended for use in medical device applications that include:

Medical device prototypes
Anatomical modelling
Investment casting patterns (to produce implantable hip and knee joint replacements)
Hearing aide device manufacturing
Surgical and dental drill guides
