Alumilite Silicone Mold Rubber for Molding Your 3D Prints

Turn one 3D print into many copies. Make a silicone mold of your print, then cast copies in resin or plaster. Mold making is also a way to get smooth, layer-line-free parts: perfect the master print once, and every casting comes out just as smooth.

• Platinum-cure silicone that picks up fine detail.
• Fast: demolds in 30 minutes.
• Kit sizes: 16 oz or 32 oz.
• FDA compliant, according to Alumilite.

Tips for 3D-printed masters: the silicone copies everything, including layer lines, so sand and prime your print first. Some materials stop platinum silicone from curing (cure inhibition), including uncured resin, so fully cure resin prints and test a small spot first. Wear nitrile gloves and mix in a ventilated area.
