I have used www.shapeways.com for 3d printing a couple of times. And I wonder if I can use this to print patterns or moulds. Does anyone have experience with printing patterns/moulds?

The material shapeways use is called PA 2200

Hi everyone,

I'm very much at the beginning of making composite parts and have just ordered some materials.

I want to make some airhorns/stacks for my car and planed to get the mould 3D printed out of ABS (Tg around 120°C) and then seal it with a thin layer of high temp epoxy.

I bought some braided cf sleeves (in combination with high temp epoxy) and will try how that works first but also got some prepreg (hence the goal to make a mould which can take 100°C or more). 

Is there anything I'm missing that would speak against my above mentioned plan (incompatability of resins, chemical reactions etc)?

If there aren't any objections I'll give it a go later this summer/early autumn. Currently temps are too high (30°C or more in my working area).

Thanks for any input.
