Avoid clogs with PLA Composites and all-metal hotends

Posted by Alex Dick on

Does your printer stop extruding on the first layer?  Or does it clog later in a print?  Is your print quality inconsistent with missing cross-sections?   Or does your printer fail on small, intricate cross-sections especially when printing slow? If your extruder gear ever grinds or slips on your filament, you’ll want to read below! Jams and clogs are often from a combination of excessive heat and non-optimal material flow.  This effect is worsened by poorly cooled all-metal hot ends, high torque extruder gears, small nozzles/layers, slow printing speeds, too thin first layer, and excessive retraction. To get more reliable results with PLA composites and all-metal hotends in particular,...
