iglidur® Tribo filament and iglidur® bar stock in comparison

In the latest test from the igus® plain bearing laboratory, drive nuts made from the materials iglidur® i180 and iglidur® J260 were realistically tested using 3D printing. For further comparison, drive nuts made from iglidur® bar stock and a drive nut printed from ABS were also used.

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

Conclusion:

The result confirms the previous tests carried out: The drive nuts made from iglidur® tribo-filament using 3D printing are comparable in terms of wear behaviour to the drive nuts made from iglidur® bar stock.
