Standard Value
Example
If the internal angles of the model are sharp corners or are less than R3, machining of around R3 will be applied.
(If you would like the internal angle to be finished to a sharp corner or to less than R3, contact meviy support for an estimate.)
Dimensional Changes for Clear Resin
Unlike metal, resin is a material that easily deforms as a result of temperature and humidity and changes in dimensions.
Accuracy is assured in the following way:
Testing is conducted in a temperature- and humidity-controlled environment
Accuracy assurance is based on the results of inspections performed immediately before shipment.
