michael-
as a former dtm applications manager, i can tell you that you are heading down a tough road if you want to use the wax dipping method. i have done it, and while not technically difficult, it is still a bit of a pain. if you must, you can heat it on the stove, then dip the parts- which i assume are polycarbonate. if the parts are trueform, dipping in hot wax is niether necessary or a good idea. the melting temperature of trueform is low enough that you may find some deformed features after dipping. i wrote and compiled lots of info on prepping trueform parts while at dtm, and they should still be able to hook you up with it. as for getting the wax, i believe the company you want is j.m. mcgoffin (that may not be exact, but it's close). any investment casting foundry should be able to help you with that info, or try the thomas register.

Dear List,
I wonder what results have been garnered to prepare a sls master for
casting in the following manner:
Coat the master with wax either by dipping or applying to surface.
The goal here is to minimize the sandy texture of the sls part in
casting.
Does anyone have any experience with this? What kind of wax do you use?
Is it better to dip or to apply? Your replies are appreciated in
advance. Please don't suggest a different rp process.
thanks
