For the test, letters from a to g were printed in the test font DIN Pro. The FDM 3D printing-method was used. The individual letters were used to test how high the 3D-printed letters must be to obtain a beautiful printed image on a Grafix. They were printed from 23.56 mm to 25 mm. Later the minimum text size (in pt) for an 3D printer was tested. Better results can be obtained by using the SLA method, which has not been tested yet. The tests showed several problems, so that Grafix turned out to be unsuitable for letterpress as such and the final prints were printed using a platen press.
