>>Process Features
>Accuracy
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.
>Machine sizes
Vary from circa **0 x **0 x **5 mm (maximum tool size) up to
***0x**0x**0mm.
