Until now, the fully automated coffee machine cup tray was adjusted to the cup size by hand. To fully automate tray adjustment, the project team from Maschinenbauschule Ansbach, a mechanical engineering educational institution, developed a motor-driven moveable cup tray with sensor-controlled height adjustment. The height adjustment mechanics used a motor, a 3D printed shaft end support, and a 3D printed lead screw. The 3D printed parts made of the iglide i6 high-performance polymer have excellent operating properties, stability, and service life. The tribologically optimized plastic is also food-compliant according to FDA and EU 10/2011.
