Somos® BioClear™
Stereolithography

Improve efficiency with clear, accurate guides and models.
Perform faster, more accurate procedures withcustomized cutting guides and surgical models
made with Somos® BioClear. Not only will thisdecrease the recovery time for patients, it can also
lessen the chances of repeat procedures.
Somos® BioClear fulfills the requirements for nonimplantable limited body contact (<24hr) medicaland dental applications. Somos® BioClear has passed
stringent ISO 10993-5 Cytotoxicity, ISO 10993-10
Irritation & Sensitization and USP ClassVI testing, after following the cleaning procedure as
described in the Somos® BioClear user guide.
Parts produced from Somos® BioClear are accurate,
clear and have ABS-like mechanical properties anda good combination of strength and toughness. The
material is resistant to moisture and many common
solvents and chemicals.
