- What was needed: Components for the mechanism of an automatic cup tray adjustment for a fully automatic coffee machine
- Manufacturing method: Selective laser sintering
- Requirements: Food conformity, strength, stability, good operation properties, dimensional accuracy
- Material: iglidur I6
- Industry: Vending machinery
- Success from the collaboration: High abrasion resistance, toughness, and long service life, food conformity according to FDA and EU 10/2011
The application at a glance: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 iglidur I6 high-performance polymer have excellent operating properties, stability, and service life. The tribologically optimised plastic is also
food-compliant according to FDA and EU 10/2011.
