•TPU has rubber elasticity, for soft material printing, speeds need to be set a little slower, around 30-50mm/s.
•The printing accuracy of soft materials should be set a bit larger.
•If you set the height of the layer to be too small, it can be difficult to print, a layer height of 0.3mm or 0.4mm can achieve very fine and smooth results.
•The operation can be more difficult than other materials. Most flexible filament printing issues are related to model extrusion structure, feeding needs an active drive extruder.
•Because it is a soft and elastic material, TPU can occasionally get stuck on the bite gear due to resistance, Aim for high temperature and slow printing, and keep it free from dragging and snagging.
•Because the TPU itself is particularly fluid, particularly delicate, set the accuracy of printing 0.3mm can achieve the accuracy of PLA 0.1mm!
