Hi
I've been reading up on the reasons behind, and the history of the
development of the Epoxy resins for SLA's and I came across the following
list in a paper by Max Hunziker, Adran Schulthess and Manfred Hofmann from
Ciba regarding the suitability of radically- (Acrylate-based) or
cationically- (Epoxy or Vinylether- based) polymerized resins for individual
applications:
Concept models, visualization R (C)
Form, fit and function R,C
Tooling Applications, high precision C
Investment Casting C, (R)
Medical Applications R
I guess the brackets () mean that use of this kind of resin is possible but
not recommended. My question is threefold:
(i) Is this list still accurate or do some additions changes need to
be made ?
(ii) Why are cationic resins (i.e. Epoxies) not suitable for medical
applications ?
(iii) Who uses the acrylates any more and why, will they ultimately
disappear as concept modellers become more widely used ?
As usual any comments welcome.
Regards.
Chris.
