> igus – 3D printed gear wheels beat standard materials in the test

Germany, Cologne – Expanding the range of materials for additive production



3D printed gear wheels from igus beat standard materials in the test. igus is expanding its range of materials for additive production with a second laser sintering material.

Laser sintering material for additive manufacturing

The motion plastics specialist igus has expanded its 3D print range and now offers a laser sintering material, which is particularly suitable for the additive manufacture of gear wheels. The new material iglidur I6 for selective laser sintering (SLS) is characterised by a wear resistance of at least six times than that of standard materials, thereby extending the service life of moving applications.

Special parts can be printed easily

Today, additive manufacturing is becoming an important topic in the industry. This is mainly due to the fact that special parts can be printed easily, cost-effectively and quickly from individual parts up to medium size batches. If the customer is looking for a wear-resistant custom-made gear wheel that can withstand the high demands of moving applications, the igus 3D print service offers a selective laser sintering. The process is very precise and provides detailed and accurate surfaces, which makes it particularly suitable for the printing of gear wheels. For example, batches of special gear wheels with four-digit quantities are now being implemented at igus. At the same time, the customers consciously opt for the additive production with iglidur I3 due to cost advantages and a long service life. Now, the iglidur I6 laser sintering material has been specially developed for lubrication-free and maintenance-free gear-wheel applications to further increase the service life of gear wheels. The new material now expands the already existing range of six Tribo-Filaments for the FDM method and iglidur I3 for the SLS process.

Convincing results in the test lab for the new gear-wheel material

The in-house test laboratory with a floor area of 2,750 square metres shows that the new material for gear wheels has a particularly high wear resistance and therefore a particularly long service life. In the igus test lab, iglidur I6 was outstanding compared to the conventional materials for SLS printing. In the test a worm wheel was tested with 5 Nm torque and 12 rpm. The gear wheel made of the standard laser sintering material PA12 remained stationary after 521 cycles since the coefficient of friction had increased too much. The gear wheel made from the new laser sintering material iglidur I6 showed minor wear after 1 million cycles and was still fully functional. In the test, the new laser sintering material iglidur I6 could also assert itself clearly against machined gear wheels. Gear wheels made of POM had total wear after 621,000 cycles, while milled PBT gear wheels broke after 155,000 cycles.
