I’m new to 3d printing and have just started using XYZ 3d printer with my students. And I’m not sure if I need to buy a 3d scanner to improve our prints at class. I’ve read some articles about 3d scanning and it seems to be great for professionals to create high-quality products (at least, according to this article). I want to create better 3d prints with the students but at the same time 3d scanners seem to be too complicated and expensive for my educational purposes…Do you use 3d scanner with your 3d printer? Is it worth buying?
