In context: Several recent experiments have broadened the potential applications for 3D printing. Although most users wouldn't consider hot glue a viable building material, it has important ...

If you’re building a 3D printer, the most complicated part is the extruder. This part uses a series of gears to pull plastic filament off of a spool, heats it up, and squirts it out in a manner ...

Researchers created a special glue gun that can 3D print a bone-like substance for fracture repair during surgery and have tested it in early experiments. The prime motive of this innovation is to ...

Have a look at the object to the right. Using a conventional fused deposition printer, how would you print the object? There’s no flat surface to lay on the bed without generating a lot of overhangs.

Researchers pioneer binder-free 3D printing of glass, using light to form precise silica structures for optics, medicine, and ...
