The guys over at 37 Signals posted this to their blog and I thought it was so awesome I had to post it to ours as well. This is the best public service announcement I have ever seen. One of the unique parts of Inventables is we are trying to help vendors communicate complex materials and components to prospective buyers at a glance. This short commercial does an incredible job at communicating without one spoken word.
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
