Conclusion

Using the EFUGY TPU filament with a 0.4mm nozzle diameter requires precise settings to ensure optimal print quality. The above settings are tailored to the "Simplified 3D" slicer software and are aimed to consistently provide you with high-quality prints. While these settings are a great starting point, slight adjustments might be needed based on your printer's specificities and personal preferences. Happy printing!

• Unsupported area threshold: 50.0 sqmm

• Extra inflation distance: 0.00mm

• Bridging extrusion multiplier: 100%

• Bridging speed multiplier: 100%

Filament Properties:

• Filament Diameter: 1.7500mm

• Filament Density: 1.25 grams/cm^3

Advanced Settings:

• External Thin Wall Type: Perimeters Only

• Internal Thin Wall Type: Allow Gap Fill

• Allowed Perimeter Overlap: 10%

• Minimum Extrusion Length: 1.00mm

• Minimum Printing Width: 50%

• Maximum Printing Width: 200%

• Endpoint Extension Distance: 0.20mm

• Tool Change Retraction Distance: 12.00mm

Other Important Checkpoints:

• Allow zeroing of extrusion distances (i.e. G92 E0).

• Ensure firmware supports "sticky" parameters.

• Adjust printing speed for layers below 15.0 sec.

• Enable only retraction when crossing open spaces, force retraction between layers, and only wipe extruder for outer-most perimeters. Please make sure you avoid crossing the outline for travel movements.

Starting Script:

Ensure that your starting script includes the following commands for optimal results:

G28 : home all axes
G1 Z5 F3000; lift
G1 X20 Y2 F1500; avoid binder clips
G1 Z0.2 F3000; get ready to prime G92 E0 ; reset extrusion distance
G1 Y80 E10 F600 ; prime nozzle
G1 Y100 F5000 ; quick wipe
