Tips and tricks!
Easy sawing of the models, even on the next day:
After lifting the impression, (after approx. 30 minutes) store the model-tray model in a hydrobox (airtight closable plastic container with a moist foam insert).
The model will not harden and the hard metal saw blade will not become dull prematurely!
model-trays can be poured out up to 5x.
For reasons of precision, they should be replaced at that time.
