Hi Awerby, thanks for the info. Yes this is the Photocentric Liquid Crystal 10". We are trying to help a customer find a suitable foundry.
Can we ask, have you ever run both traditional lost wax castings along side resins? Our feedback from one foundry was that they could not do this due to danger of ignition of the wax, spoiling those castings?
presumably, introducing the air into the kiln would increase the likely hood of this ignition??
Casting is not our thing, hence this information gathering exercise.

I saw one of those printers at the Inside 3D Printing show in San Diego, and wrote about it in my blog: http://computersculpture.com/blog#fr...ech2016_anchor
I haven't burned out wax patterns at the same time as resin ones, although I use wax for spruing the resin. I don't see an issue with wax ignition, since the wax will run out and ignite (if it's going to do that) well before the resin starts combusting. If the wax does ignite, it's not a problem; the kiln and molds are impervious to a little flame, in my experience anyway. But the resin needs a longer and hotter burnout cycle than normal wax patterns, as well as the Plasticast investment, so I keep them separate.
Sorry, I don't know who does this in the UK, but over here people that do jewelry casting don't usually call themselves "foundries" - that's reserved for those doing larger castings. Search for "jewellery casting UK" and ask the companies you find that way if they deal with resin models.

Try contacting JH May models and prototypes. They already offer a rapid casting service from SL resin models, so they are probably the best placed to speak to about this process.

Hope this helps,
