Description

Tolerances vary depending on material and supplier, however as a general rule using ± 0.*5mm to **0mm and ± 0.*5% thereafter will provide a 'safe' estimate. Note these are process tolerances and should be applied on top of any master part tolerance.
Minimum Feature Size: In a similar way to injection moulding, this is determined by the ability to get the polyurethane to 'flow' into small features. As a wall section, 1mm is about the minimum achievable, however if the area is small enough this can be improved upon.
