If you are working on sensitive electronic components you might consider using a thermally conductive plastic compounds to transfer heat away. High heat levels can often either disable or destroy an electronic component. When used properly a thermally conductive plastic part can be used to minimize the number of parts in an assembly and reduce the entire weight of the assembly. Unlike metal, thermally conductive plastic parts can be processed with injection molding or extruding into sheet or tape form.
Choosing the right 3D carving bit for the job at hand can be an extremely important factor in whether a project comes out amazingly, alright, or not at all. Combine that with having more choices of bits than materials, and choosing the right bit can be quite a difficult task. However, by answering a simple set of questions, you can greatly simplify your choice of bit. Here are the things you need to ask: What material am I cutting? What is my machine capable of? What shape am I cutting? Let’s quickly go through each of these and what they mean. What material am I cutting? Your material is one of the most important single factors in choosing a bit. Materials have a lot of properties that matter both for your design and cutting (hardness, density, size) as well as just for cutting (how does it chip? melting point, thermal conductivity). For any combination of these properties, one thing remains constant: your bit must be sharp. A dull bit will always cut
