You are, of course, exactly right. Right now 3D printing is mostly in the "neato" stage, and is being oversold by a lot of actors. The materials are limited, costly, and prohibitive, and the process is extremely slow and of moderate accuracy. It is getting better, of course, but there are some hard, sober limits on the sorts of materials that can be extruded and modeled like this.
- mseidl 12y agoCheap consumer 3d printing sucks. Keep in mind that if there is something cheap now like 3d printing, it's been around for 20+ years. And it has. Königsegg (The car company) 3d prints their turbos and doesn't do any machining to finish the impeller. Think of how accurate it has to be to spin to 100-150k rpm or more. https://www.youtube.com/watch?v=DNedUZxP8NU https://www.youtube.com/watch?v=DNedUZxP8NU
