Update 2024/02/25: New version v2 with axes labels and new overhangs test on the top faces

This is a stress test that I designed to calibrate the settings of my 3D printer for ASA and ABS materials, but it can also be used for other types of filaments.

Bed adhesion: the size of the base is 80 mm, its height is 3 mm and the vertices are square. If the bottom plane tends to rise from the bed, then raise the bed temperatures and/or use glue.

[ASA] Bed adhesion and quality of top surfaces

Flow: the large planar surfaces of the base and the second level allow you to check the quality of the print and validate the flow and pressure advance settings. If there is too little or too much material near the edges of the plane, then perform a Flow Dynamic Calibration to find the correct K value for the filament, and a Flow Rate Calibration to fix the flow rate parameters for the material

Wall quality: the five different wall types/sizes allow you to tune the external wall speed. The bottom of the sphere and the 45% surface slopes (v2) on the top allow you to tune the overhang settings (cooling and speed).

Small perimeters: the two top cylinders allow you to check the quality of small perimeter settings.

Precision checks:

Base width: 80 mm
Second base width: 50 mm
Square column width: 15 mm
Sphere diameter: 30 mm
First cylinder diameter: 10 mm
Second cilinder diameter: 5 mm
Hole diameter: 3 mm
Hole wall: 1 mm

Belt tensioning: if the external walls present wobbles then you must fix the belt tension of your printer.

Robustness and layer adhesion: try to break the column by hand. If you can't then the temperature, the infill, and the flow settings are very good.

If you want to remix the model, you can find it on OnShape.

Happy tuning… and do not hesitate to add comments to improve the model.

Thanks for making such a helpful test print. I am starting my first attempt to use ABS filament and printing this makes me feel a lot better having success. Two question: For all of the dimensions listed in above I get very close, see photo below (around 0.25 to 0.5 mm below planned dimensions). Is that good enough? I would like to get them closer to planned value. Is there any method to go about correcting the values? All the surface finishes are perfect and the X and Y dimensions are very close to each other. The X and Y characters on the vertical faces are clean with no distortion. The bottom square came off completely flat and looks good. I rated this file 5 stars.

The final dimension of an object printed with ABS and ASA mostly depends on the shrinkage of the material. Your values seem good to me. If you want something "perfect" you can try to play with the "Precision" parameters, in particular with "hole compensation" and "contour compensation".

Replying to @myzhar :

Thanks for pointing me in the right direction, I never would have found those settings...... I think adjusting those values will be a step down the line in my learning curve but now I know where to go.

@Unimog

Thank you for the test is very interesting! I have always the same problem also at 100° bed.... I'm using bambu lab Asa any suggestion? Thank you

@myzhar

What I normally do it to turn on the bed at 100°C and wait at least 15 minutes before starting the print to heat the closed chamber and let it reach ~40°C. If this is not enough, a layer of glue on the bed normally solves the issue.
