I suppose, the problem would be the burnout, but I’d be talking to
the person that printed them and see if they are willing to use a
different brand of wax.
Some of the guys over here in Oz use a more durable wax (in fact I
dropped a wax model at a trade show and it bounced).
I sometimes do lost foam casting, and it’s far less refined than
jewellery casting, and to glue and add detail I use a fillet
material from Blehm plastics that is designed to burn out.
