When you're using a 3D printer, sometimes you want to start and stop extruding plastic within a layer to create open spaces. This is called retraction, and it can be tricky to manage, as described in this video and the next.
- [Narrator] When you're using a 3D printer, … sometimes you want to stop extruding … and create multiple islands within a layer … with open spaces between. … There's pressure in the printer's nozzle … that can cause plastic to continue to leak out, though, … even when you stop extruding. … To reduce this oozing, the printer can pull back … on the filament to relieve pressure in the hot zone. … This is called retraction. … If you retract too little, you'll get stringing, … which is what you see here. … If you retract too much, you may have filament jams. … In this video, we'll talk about … what the retraction settings mean. … If you're not having stringing issues, … it's usually best to leave retraction settings … at your manufacturer's defaults. … Many of the issues we talk about in this video … will not be visible in simulated print in slicing software. … One of the challenges is that the reality of the print … may be a little different than what is on the screen. … - [ Narrator] The retraction settings …
