Q: Why is 3D printing still so slow?
A: Because, let's be real, you're probably still using a 3D printer that's older than your grandmother.
Q: Can I use any material for 3D printing?
A: Only if it's a type of metal or plastic that's specifically designed for 3D printing. Otherwise, you'll end up with a nice set of exploding, firework-filled earrings.
Q: Will 3D printing replace my job?
A: No, but it will probably make you realize that your job is just a fancy form of 3D printing, and you're just a lowly "operator."
