Manufacturing standards and tolerances
What a tolerance figure means, and what to keep in mind when you design your part.
Typical tolerance
The tolerance shown is what the process holds on ordinary geometry; use it for planning. It is not a guaranteed figure for each part.
If you need a tighter tolerance
If you state a tolerance on the quote, the system checks it. If it is tighter than the process typically holds, the quote tells you before you order; we do not charge for a dimension we cannot hold.
Print orientation and strength
Layer-built parts are weaker across the layers than along them. Your part is sliced and priced in the orientation you upload it in; if strength needs a particular orientation, upload the model that way round.
Shrinkage and warp
Semi-crystalline and high-temperature materials shrink and warp more than PLA. Large flat faces and long thin spans are the usual problems. The manufacturability warnings show these on your own part rather than as generic advice.
Thin-wall estimates
The thinnest-wall figure on a quote is an estimate from analysing the 3D model, not a measurement. Treat it as a reminder to check your CAD.
