Vacuum casting is a rapid prototyping process used in manufacturing industries to create vacuum products and functional plastic parts. It is conducted with a silicone master model made by SLA or CNC. In this process, a plastic sheet is heated to make it soft and pliable to stretch and vacuum on a mold. When cooled,
3D modeling is the first step towards 3D printing any intended object. You can design a 3D model in any one of the several available advanced CAD software programs, print in different materials, and use different printing technologies. The fact that there are so many options available only add to our confusion, and we face
