More affordable than ever, 3D printers are booming for personal, professional, and educational use. Here's everything to know before you buy one, along with the top models from our hands-on testing.

NARRATOR: It's crunch time for the 3D crew. And who's going to take home the coveted, and totally pointless, prize of, eh… most properties? Two cubes high-five as they prepare to compete.

Today's affordable 3D printers will likely surprise you: You can get a smooth-working machine with useful features once found only in high-end models. Starting at just $250, these are the top ...

Faces - A face is a flat surface on a 3D shape. For example a cube has 6 faces. Edges - An edge is where two faces meet. For example a cube has 12 edges. Vertices - A vertex is a corner where ...

The rise of the consumer 3D printer has yielded amazing devices for designers, engineers, hobbyists, tinkerers, and schools alike. I've been reviewing 3D printers for PCMag since the first widely ...
