3D Printing & Imaging

The Brutstruder appears to be a powerful plastic extruder, which is the part of a 3d printer that pushes out hot plastic in a thin line. Actually, I’m not sure how strong this design is in comparison with the others, however I am digging the test method used to verify the design. [thanks, Marty!]

    1. He seems to be testing the feed motor part of the printer’s extruder, have a look here http://reprap.org/wiki/Mendel_extruder. The printers take a ~2mm diameter plastic rod as input and then heat it up and push it out through a ~0.5mm nozzel. I assume he is testing the force that the feed system will have avaiable to it to push the material through the extruder nozzle.

      1. Oh, yeah, that is what he is testing. It’s useful to have a system that can put out a large amount of force without breaking, so you have some extra headroom when printing.
