Although I have not developed a spinal "hunch" :-) I am the
self-proclaimed poster child for stereolithography resin safety.
Although I worked with acrylate SL resins for years, I was immediately
allergic to SL epoxy resins. Symtoms include itching, skin rashes,
localized skin swelling and skin cracking. If you work with ANY
chemical, repeated dermal and/or respiratory exposure MAY (and likely
will) result in chemical sensitization. This is irreversible. Yet, lab
procedures exist to permit me to work with SL epoxy resins on a daily

Since you did not specify any particular RP system, I am not sure what
in particular you are looking for. I can offer you our SL
Laboratory safety manual for downloading at I also have a "safety video"
which can be borrowed for copying. The video deals with personal
protective equipment I use to eliminate resin exposure. This was
presented at the 1997 North American 3D System's SL User's Group in
Orlando, Florida. Video copying is on an "Honor System" as I have only
2 copies which float around the USA (or further?) from company to
company. Recently, 3D Systems obtained a copy and may distribute upon
request. The contact there is Nina Bach, 3D Systems Education Center,

Although epoxies (in all forms) are known dermal sensitizers, they can
be safely handled with appropriate personal protective equipment and
proper work habits.
