I am currently in the middle of a projet watch part and received my first "prototype" made from WSF in night black. I was impressed with the overall outcome, but the night black was more dark grey. I have just got a message back from my test pilot saying that

"It can be made to fit, but its a little tight around the lugs, so a half mill will have to be shaved off here and there"

If the design was a 1:1 copy should I expect these problems? Would I get a different result if it was in stainless steel or would it be the same tolerence?

Thanks for any help

I'd read down this extensive detail of deviations in the design rules for WSF http://www.shapeways.com/tutorials/design_rules_for_3d_print ing
Each material has different tolerances, stainless is less likely to be exact or even 2 prints be exactly the same because it's a 2 step process with printing and infusing. Stainless is accurate to 2mm from it's design rules http://www.shapeways.com/design-rules/stainless-steel

So WSF is the better of the two materials? Hmm I may have to review my process and go for an injection mould or something. I am looking at a run of about 100 prints of 4 different parts (not all at once) so for me to adjust each one is going to be time consuming.

I need it to have a smooth finish and for it to be strong and accurate. Is there any other options?

Thanks for any help

The most accurate would be Frosted Ultra Detail. It should have a smooth finish. There have been problems lately with ribbed surfaces, but from what I've heard that the problem is being solved.

Thanks for that. I will give that a go. Hopefully I can find my solution with shapeways.

Suggestions are most welcome Smile
