Wear is an important aspect of parts in moving applications. Wear-resistant polymers such as our iglidur materials are the solution for minimising wear and increasing the parts' service life. Due to the tribological properties, the iglidur materials are perfect for all application areas in which good coefficient of friction and very low wear are important.
The igus test laboratory covers 3,800m². In an extensive series of experiments, igus is researching and developing new 3D printing materials for moving applicationsin the industry's largest test laboratory. All materials are tested regarding their tribological properties in different test series so as to minimise wear and maintenance intervals. They are particularly low-friction and wear-resistant and ensure a lubrication-free and low-maintenance operation. iglidur polymers offer very good tribological properties and ensure a longer service life for polymer components.
In our test lab, we continuously test tribological properties of 3D printed parts based on DIN ISO 7148-2. The series of tests cover linear, pivoting and rotary movements on different shaft materials. With our filament iglidur® J260-PF, friction values and wear were low in all tests, while the standard ABS material quickly failed the rotating test on the stainless steel shaft. The printed plain bearings made from the iglidur special filament had a similar wear resistance to the standard iglidur injection-moulded parts on all test rigs. Thanks to the wear-resistant plastic iglidur I3 and an optimised tooth shape, our 3D-printed gears achieve a longer service life than standard materials.
Test parameters:
Y = wear rate [μm/km]
1. ABS (FDM)
2. iglidur® I180 (FDM)
3. iglidur® I3 (SLS)
4. iglidur® J injection-moulded
Test result:
the long-stroke test shows lower coefficient of wear by factor 15 for iglidur I180 (FDM) and even by factor 33 for iglidur I3 (SLS). Due to the very good tribological properties, the wear-resistant iglidur materials are ideal for long-stroke applications, such as X-Y gantries for pick-and-place applications or plain bearings and glide bars in the 3D printer.
Test parameters:
Y = wear rate [μm/km]
1. ABS (FDM)
2. iglidur® J260 (FDM)
3. iglidur® J260 (FDM)
Test result:
the plain bearings made of wear-resistant polymer iglidur J260 have similarly good wear rates, independent from the manufacturing method. iglidur J260 injection-moulding plain bearings and bearings printed in 3D were tested with the same load and surface speed.
In addition, this test shows that with our iglidur 3D printing materials coefficient of friction and abrasive wear are a lot lower than with standard ABS materials thanks to tribological properties.
Test parameters:
Y= wear rate [µm/km]
Test result:
During the swivel test, the tribological properties of the iglidur filaments lead to a 50 times higher abrasion resistance compared to the standard 3D printing materials (e.g. ABS). Wear-resistant polymer ensures a much longer service life of plain bearings and other components.
Test parameters:
Y= wear rate [µm/km]
1. iglidur® I3 (SLS)
2. iglidur® I180 (FDM)
3. iglidur® G injection-moulded
4. iglidur® W300 injection-moulded
Test result:
this heavy load test shows that plain bearings printed in 3D (with the SLS printing method) withstand loads of up to 45MPa surface pressure. It demonstrates that abrasive wear and tribological properties are just as good as withplain bearings made with injection moulding. Plain bearings with a diameter and length of 20mm were tested, i.e. the 3D printed plain bearing was loaded with 1,800kg. The test results show that plain bearings made of wear-resistant iglidur polymers are also suitable for heavy-duty applications.
Test parameters:
Y = wear rate [mg/km]
1. ABS (FDM)
2. iglidur® I180 (FDM)
3. iglidur® J260 (FDM)
4. iglidur® I3 (SLS)
5. iglidur® J injection-moulded
Test result:
in this test, the wear resistance of igus 3D printing materials is higher by factor 6 to factor 18 compared to conventional materials, depending on 3D printing materials and method.
Printing drive nuts in 3D offers cost advantages especially with low quantities, as the thread can be produced directly in the 3D printer and therefore no expensive tool for cutting the thread is required. The thread only needs to be constructed in the model.

X = duration [h]
1. PA12 (SLS)
2. iglidur I3 (SLS)
Test result:
the tribological properties of iglidur I3 are better by factor 2 in the test as with the standard 3D printing materials. This is due to the fact that iglidur materials contain solid lubricants, which lower coefficient of friction and significantly increase wear resistance. Wear-resistant polymers and tribological properties are helpful for designing motors and drive forces, as half the friction only requires half the drive force.
