Frequently asked questions
What type of silicone do I use to make the mold?
Use two-component silicone (platinum or tin). Platinum is more expensive but doesn't shrink and is food-safe. Tin is more affordable for non-food projects. Both are available at mold supply stores.
Can I use the mold for chocolate?
Yes, platinum silicone is suitable for chocolate. Make sure the printed mold is PETG (withstands up to 80°C) and use food-grade silicone.
How many uses does a silicone mold have?
A quality silicone mold can be used hundreds of times. With proper care (gentle washing, avoiding cuts), it lasts for years.
Do I need a release agent?
Silicone doesn't stick to most materials, but a release spray helps with very fine details or shapes with undercuts.
