The DuraForm and the Fine nylon materials have both been tested by NAmSA
for material biocompatibility (per FDA and ISO guidance). All results were
negative, DuraForm and Fine nylon caused no cytotoxic reactions with any of
the tests. The tests that were performed verified that the SLS materials
were safe for limited contact (< 24 hours) in all categories, including
implant devices. Both of these materials can be sterilized with an
autoclave.

Dear rp-ml
I have a question regarding the use of RP for biomodelling. Some of the
materials for use in RP machines can be sterilised to certified levels so
that models can be taken into operating theatres. However, I understand
that these models can only be sterilised using gamma rays. Is this true, or
can models be sterilised using other (and if so, what other) methods?
Also, SLS models have a granular surface. Are there any problems associated
with using the medical grade SLS material in terms of finishing (coatings)
and particulate contamination?
Regards
