In a breakthrough for nanoscience, polymer engineers have made such a mold for nanostructures that can shape liquid silicon out of an organic polymer material. This paves the way for perfect, 3-D, ...

If you’ve got one of something and you want more, duplicating it with a silicone mold can be a great way to go. This is applicable to 3D printing something you need many copies of, and a whole variety ...

In this episode Ben shows how to use silicone to make reusable mold for casting concrete. This is an easy process for making a concrete copy of an existing object. I used Mold Star 30 silicone rubber ...

Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids ...
