Does Shapeways have a dimensional accuracy that they promise to maintain on printed WSF models? is there a refund for models that measure off the tolerance range? are the WSF printers they use professional accurate machines?
You can find the tolerances on our guidelines page here: https://www.shapeways.com/materials/strong-flexible-design-g uidelines Tolerances for WSF are ± 0.15mm, then ± 0.15% of longest axis. Tolerances for Frosted Ultra Detail are ± 0.025-0.05mm for every 25.4mm And you can read more in detail about the machines and their capabilities here: https://www.shapeways.com/tutorials/design_rules_for_3d_prin ting Different materials use different machines and processes, so the tolerances vary accordingly.
