Problem thin wall printing

Recommended Posts

Posted · Problem thin wall printing

I printed a similar model from the same site, and it required some playing with settings and trying a few different filaments to get good results.

Some filaments are more tolerant of retractions than others. These models can have retractions every 2 or 3 second continuously for minutes. It's a real world extruder torture test. Esun's PLA+ was the filament I settled on, pushed by a Bondtech extruder on a UM2.

Simplify worked for me as a slicer, using mostly the settings suggested by the model's creator.

Also I think I reduced the total retractions for this model in S3D by setting the minimum travel distance for a retraction to something like 7 mm.

Good luck!  It's satisfying when you get it working well and produce a real plane

Indeed for heavy retractions jobs you need a extruder that can keep with thousands of retractions without any issue. Specially when there's no infill to distance the gab between retractions the um2/um2+ knurled bolt can destroy the filament (PLA specially since is easy to grind). A bondtech feeder is the best approach. Is always good to remove nuisances of the machine and be able to print just the way you want, with less limits.
