Selective laser sintering material: iglidur® I6-PL The material iglidur I6 developed for laser sintering was specifically intended for use as a worm wheel. The tests in the igus® test laboratory resulted in a longer service life than for conventional ones - e.g. POM milled finished gears. This greatly increases the flexibility in the design of gears, since no tools are necessary due to the laser sintering process and gears can be produced efficiently with no minimum order quantity. Furthermore, iglidur I6 is very well suited for snap connections due to the higher elongation at break.
