Figure 4 EGGSHELL-AMB 10

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 Tips

  1. General best practices apply, as seen in the Figure 4 Print Material Quick Reference.
  2. When using parts to create injection molds, keep supports on the part to hold it steady during injection and current process of silicones.

  3. 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:

    1. When cleaning parts, use acetone instead of IPA, following the same cleaning instructions for IPA from the Post-Processing Guide. Follow all SDS and safety precautions when using any solvent for cleaning parts.

    2. Dry parts in an oven at 60°C (140°F) for one hour before post curing.

    3. Post-cure parts for 180 minutes.

    4. Reheat parts for one hour at 100°C (212°F).

    5. Cure injected materials at an elevated temperature, such as 60°C (140°F), for one hour if material allows.

    6. Clean parts with soapy water after post-curing. Dry parts thoroughly.
