iglidur® tribo-filament and iglidur® bar stock in comparison

Test setup for drive nut In the latest test from the igus® plain bearing laboratory, 3D-printed drive nuts made of the materials iglidur® i180 and iglidur® J260 were tested in realistic conditions. For further comparison, drive nuts made from iglidur® bar stock and a drive nut printed from ABS were also included.

In the test, a drylin® SHT lead screw linear system was set up vertically and the drive nut was subjected to a load of 129N (Image 1). The stroke length amounted to 370mm and the spindle speed to 290rpm. A dryspin® DST high-helix lead screw was used, which is specially tailored to the lubrication-free iglidur® high-performance polymers and thus guarantees a longer service life.

Wear-resistant drive nut

Wear-resistant drive nut
Y = Wear rate [mg/km]
Stroke = 370 mm
Lead screw speed = 290 rev/min
1 = ABS printed
2 = iglidur® I180 printed
3 = iglidur® J260 printed
4 = iglidur® R bar stock
5 = iglidur® J bar stock

Conclusion:

The result confirms earlier tests: the drive nuts manufactured with 3D printing from iglidur® tribo-filament have comparable wear characteristics to the drive nuts made from iglidur® bar stock.
