There are many overhang test models with 60, 70 or 80 degree overhangs, but do they ever actually print 70 degree overhangs? In the actual shape of the model to be printed, even an overhang of only 55 degrees is extremely difficult.

This test uses a model that eliminates the extreme angle and allows for more realistic situations to be tested.

Three test models with 45, 50, and 55 degree overhangs are available. 

Test 45 degree

  • PLA: Should be clean print.
  • PETG, ABS, ASA, PC, CF: It is desirable to be able to print as cleanly as possible even at low fan speeds.

Test 50 degree

  • PLA: If the cooling is good, it could print beautifully.
  • PETG, ABS, ASA, PC, CF: Well, it can't be helped...

Test 55 degree

  • PLA: If you have great cooling, maybe it can print clean?

Print Settings:

  • Material: PLA, PETG, ABS, PC, CF, etc..
  • Layer height: 0.20mm
  • Supports: No
  • Infill: 15%
