model for dimension test

We designed a 20 mm cube and subtracted a 10 mm cube from the inside of the first cube.

Designed dimensions are:
20 mm cube
10 mm cube
5 mm wall

Results

Difference between designed dimensions and printed dimensions:

Designed dimensions Measured dimensions
Cube: 20 mm in X, Y, Z 20 mm in Z | 20,02 mm in X | 20,07 mm in Y
Cube: 10 mm in X, Y, Z 10 mm in Z | 10,01 mm in X | 10,01 mm in Y
Wall: 5 mm in X, Y 5,01 mm in X | 5,01 mm in Y

Surface finish tests

model for surface finish test

We made Neil's apparent surface finish test to visualize the angle of the print.

The model has two 8 mm radius spheres, one positive and one negative on a cuboid.

Results

The steps are actually more visible towards the top and bottom of the spheres.
