3D printers seeking to use multiple colors of filament have, until now, had to rely on purchasing multiple extruders or using multi-colored filament, neither of which was really an ideal solution. Canada-based Mosaic Manufacturing has risen to this challenge with a novel response to the desire for multiple colors used in the same 3D printed objects. Their sole-extruder method uses a brand new device, a box featuring motors, a cutter, and a connector, that uses an algorithm to change the filament color in use based on the G-code. Users can change color as regularly as every 35mm of a print job. The box can be used with virtually any 3D printer, not requiring any reconfiguration or modifications.
