3D Printing Tech Tips: How to 3D Print Standard Calibration Prints

3D Platform guides viewers through the process of printing two standard calibration prints. This process should be part of your initial setup process, and should also be printed periodically for troubleshooting.

Print ‘The Chip’
Prior to printing the calibration prints, the bed should be leveled, the build area should be prepared, and the axis should be in the home position.

First, we will select box 40x40x.5.gcode. Allow your bed to cool in order to remove your parts without damaging them. Measure the thickness of the chip with a caliper (This test print should measure between 0.60 mm and 0.75 mm).

If the nozzle is too far or too close to the build area this could be adjusted by a process of baby-stepping the distance of the nozzle from the bed. This is done on the LCD screen by selecting ‘tuning’, then Babystep Z. Turning the knob clockwise raises the extruder. Counterclockwise lowers the extruder. One click on the knob adjusts the extruder by five microns. Once you have made your adjustments you can save them by clicking ‘control’ and then ‘store memory’. This can be done while calibration prints are running, allowing immediate feedback.

After the chip has printed successfully it’s time to move on to the thin wall box. Choose file name box 40x40x15.gcode. At the completion of the calibration print, the wall thickness should be 0.70mm +/-.01mm. If the wall measures more than 0.70 mm, DECREASE the flow rate in your slicing software (extrusion multiplier). If the walls measure less than 0.70 mm, INCREASE the flow rate in your slicing software (extrusion multiplier). Repeat this step until you achieve a wall dimension of 0.69 mm – 0.71 mm.
