Those die-hard fans of delta 3D printers praise the speed and accuracy of their machines, due to the reduced weight and complexity of the moving parts. But managing to print with multiple filaments can prove difficult, given the small space necessitated by the build area. Plus, any additional weight added to the extruder slows down the printhead, defeating part of the purpose for owning a delta in the first place. Fortunately, Mathias Dragosits has been working on a solution, inventing the Wim3rl printhead: a watercooled printhead with three hotends for multiple filaments.…
