Dear All,
As one of the few remaining users of Cibatool SL-5149 Acrylate resins
I welcome any developments in the area of Durable or flexible resins.
I am presently stuck in the realm of high shrink/curl part building
problems due to the fact that 75% of the parts that we build must be
testable in either water or Stoddard solvent. This testing requires a
resin that can withstand repeated hydrostatic shocks and pressures of
0-150psi for hours at a time.
I have worked with an SLA-250 since 1990, and the only question that I
have for Ciba and 3D is: What about a resin for the HeCad Laser?
You know how many SLA-250 machines are out there, and you have all but
abandoned them in laser, software, and resin development.
A $350,000 investment to replace a perfectly good SLA-250 with a
SLA-350 just so I can use the "new" resin is insane. These are machine
tools not computers, and like every machine tool I have ever worked
with they should be upgradable.
I spent about $40,000 upgrading my SLA-250 up to a model 50 with the
Zephyr recoater last April. As I build mostly parts with trapped
volumes, this has more than paid for itself in reduced downtime due to
blade crashes.
I need a resin that can give me properties that meet my specific
requirements but I don't want to end up like so many of the current
epoxy resin users, who are now allergic to them. A resin that is
non-toxic, can be cleaned up in soapy water, and dosn't require
special waste disposal would be the best solution. I don't want much.
