Figure 4™ EGGSHELL-AMB 10 is a rigid plastic used to create sacrificial tooling that withstands silicone injection at high temperature and pressure, but breaks away easily
- General best practices apply, as seen in the Figure 4 Print Material Quick Reference.
- When using parts to create injection molds, keep supports on the part to hold it steady during injection and current process of silicones.
There are many commercial silicone and RTV materials used for eggshell molding. Use the following during post-processing with EGGSHELL-AMB 10 to improve any inhibition issues:
Clean parts as seen in the Post Processing Guide. Dry out parts in between cleanings to remove residual material/IPA. If material/sticky spots still exist after two cleanings, spray IPA on the affected area(s) of the part and blow dry.
Dry parts in an oven at 60°C (140°F) for one hour before post curing.
Post-cure parts for 90 minutes.
Reheat parts in an oven at 80°C (176°F) for 30 minutes, or 60 minutes if the part is larger or more-complex.
General Round Tip
- Best for general use for small parts up to large and large-cover parts.
- When printing small, fine parts in this material, the user may need to modify the Pillar Tip Ratio.
