Silicone Mat Raised Edge
Resin printing is a notoriously messy business, and this mat acts as the first line of defense for your desk. The raised edges are a lifesaver, as they keep spilled resin contained rather than letting it run off onto your floor. It is a simple tool, but it is one you will be glad to have the first time you knock over a vat.
Because it is made of flexible silicone, it is incredibly easy to peel off cured resin once it hardens. Just be aware that it takes up a fair amount of desk space, so verify your measurements before clearing off your workstation.
- Brand Name:Generic
- Special Features:Raised edge for containment
- Additional Feature:Large 23.6×15.8 inch size
- Additional Feature:Desk protection for printers
- Additional Feature:Resistant to printing materials
-
Skull Silicone Casting Molds
Sometimes you do not need to print a mold, you just need a reliable way to cast one. These extra large skull molds are perfect for creating decorative items or unique home accents. The silicone is soft enough to allow for easy demolding, which is vital when you are working with detailed shapes that might otherwise snag.
You can use these with various resins, waxes, or even concrete, making them a versatile addition to your creative kit. Keep in mind that deep molds like these can sometimes trap air bubbles, so tap the mold gently against your table after pouring to ensure a crisp finish.
- Brand Name:Generic

Frequently Asked Questions
Can I use a standard FDM printer for making molds?
You can, but you will spend hours sanding and filling the layer lines to get a smooth finish. FDM prints are often porous, which means the silicone will seep into the gaps and lock the master in place forever.
What is the most important step before pouring silicone?
The most critical step is applying a proper mold release agent. This thin barrier prevents the silicone from bonding to the resin master. Without it, you are essentially gluing your mold to your model.
Why does my silicone stay liquid after pouring it over my print?
This usually happens because of cure inhibition caused by the chemicals in your resin. If your print surface remains sticky or soft, the sulfur in the resin is reacting with the platinum catalyst in the silicone. You may need a clear acrylic sealant to shield the silicone from the resin surface.
Do I need a vacuum chamber for quality molds?
A vacuum chamber is useful if you want to remove trapped air bubbles from the silicone before it cures. While not strictly mandatory for simple shapes, it makes a significant difference for complex geometries with thin walls. It ensures your final casting is bubble-free and structurally sound.
How long should I let my resin print cure before using it?
You should let the print cure fully for at least 24 hours before making a mold. Some resins continue to off-gas volatile chemicals for a day or two, which can interfere with the curing process of the silicone. Patience here is the difference between a perfect mold and a ruined project.
