does an open hollow part can be printed in silver ?
This material allows you to print hollow models. However, keep in mind that you need to incorporate multiple holes or slots so that we can get rid of any unprinted wax resin.
In addition, you will need to make sure that the casting plaster is sufficiently supported or your model will not be able to be cast properly. Make as many holes or slots as you possible can.
We recommend making two or more holes or slots. Make sure the holes are spread out equally; for example on opposite ends of your design. The holes should have a diameter larger than 1.5 mm.
