Calibration print shape

2

To check my leveling etc. is correct I was going to print a wide and thin cube. My theory being that I should be able to spot any obvious separation of the layers.

Does anyone have any better shape that they print as a dry run?

Your calibration shape depends on what you want to calibrate on. Among the most popular:

  • Benchy as a general "overall" test.
  • Lattice Cubes for retraction/stringing and overall quality.
  • Two pillars to test for stringing and temperature/cooling control.
  • Spikes for retraction, stringing and temperature/cooling control.
  • Bridges for cooling control.
  • Cubes for sizing. They also allow seeing if the printer is skewed in X or Y.
  • Circles, crosshairs, and squares of just a couple layers high to determine the correct center of the print area and measure sizing.
  • Cylinders in each other to check the achievable resolution and clearance.
  • Overhang tests to test just overhangs.
  • Temperature towers for temperature and overhang.
  • Impact1 & Bend & Tension test pieces for filament properties - if you have the setups needed.

2Great list, although one not mentioned is a calibration square to measure diagonals in order to test the skewness. This is typically a large square only a few layers tall. – Perplexed Dipole – 2018-12-20T17:29:23.207

Lots of useful stuff there. How doe the bridge to test cooling control work though? – BanksySan – 2018-12-20T20:10:28.160

@BanksySan If the bridge fails or sags too much, you need more cooling. – Trish – 2018-12-20T20:33:11.520

@Trish and print slower. – 0scar – 2019-03-07T14:29:10.683
