Looking for someone to print a sand casting pattern for me.
This isn't a charity case, I'm happy to pay you to do it.
I need someone who can print a master pattern for me, solid enough that I can cast it in rubber/silicon to create a mold that I can use to make urethane working patterns for sand casting. The pattern would be ~18" wide x ~20" long x ~8" tall, shaped like a flat topped hollow dome (it's a brake drum) with attached runners/risers/sprue/etc.
What I need is someone who can accept a solid model (or STL file or whatever computer file you need) from me and produce a printed solid that is within just a very few thousandths of an inch of being exactly the size of the model.
Accuracy is very important here, because I'm casting to near net size. There will be machine work allowances built in, but you gotta be within -+0.010" pretty much everywhere (except the casting runners, sprue, etc, that stuff gets sawed off and remelted, so a bit of distortion in those parts is fine).
So, any takers?
If you're up for the challenge, PM me your email address and we can discuss our options.
Anyway, thanks for looking. I appreciate whatever help you all can give me.
