Hey Bob,
We have been using RPC 600AR for about 9 months. Most of our customers are requesting it for functional and testing models. Lately we have had a difficult time keeping up with the demand for it. We are using it in our SLA500.
Some observations:
1. We have used it as master models for RTV molding.
2. Great green strength, we can work with it immediately after the build
3. We have found it to be easier to finish than any other resins and can be polished, still has a slight yellow ting
4. Shrink is ~1.003, we have not seen any warpage or curling problems
5. Clear - not milky white like 9100 and 7540
6. Does not get brittle with age like the 8100, that I have noticed.
7. Flexibility is approximately the same as 9100 and 7540, from the samples I have
8. Can be used for quickcast
I would be glad to talk to you about it.
Jim

Subject: Flexible SLA Resins
Hi, I'm new to the list, if this has been discussed, let me know where to go to get the info, thanks.
We are interested in putting either Somos 9100, RPC 600, or Vantico 7540 in our 350. Does anyone have strong feelings about which material is better, more accurate, easier to finish, more robust, more flexible over time, etc?
While we would use primarily as sla models, we would also want to be able to use a mold patterns in a pinch. Any problems with silicone cure, finishing to a mold pattern level, and so on?
We'd appreciate any insight folks have on this subject, thanks! Bob
