iglidur® I3-PL for 3D printing via SLS

The material iglidur® I3-PL, specially developed for laser sintering, proved to have an abrasion resistance at least 3 times greater than conventional materials for laser sintering during tribologic tests in the igus® test laboratory. This means the degree of design freedom for wear resistant parts has been increased yet again.

For beta testing

Wear-resistant and low coefficients of friction

Good mechanical properties

Detail accuracy with exact surfaces

Can be processed in a similar way to commercially available SLS materials.

Typical application areas:Prototyping, small series, special machine construction, ...

Wear test, rotating: v = 0.3 m/s; p = 1 MPa; shaft: 2 SS and Cf53

Y = Wear rate [μm/km]

A = PA12 (SLS) B = PA12 + glass balls (SLS) C = iglidur® I3-PL (SLS) D = iglidur® I180-PF (FDM)

Test results:

In this rotating wear test, the abrasion resistance of iglidur® I3 is higher than that of conventional SLS materials by a factor of 4. In addition, the shafts and bearings that are shown here and were used in the test make it clear that iglidur® I3 results in considerably less stress on the mating component, the service life of which is also increased as a result.

Wear test, linear: p = 1MPa; v = 0.1 m/s; I = 5 mm

Y = Wear rate [μm/km]

A = PA12 (SLS) B = PA12 + glass balls (SLS) C = iglidur® I3-PL (SLS) D = iglidur® I180-PF (FDM)

Test results:

The results shown here from the linear short stroke test, indicate that the wear-resistance of iglidur® I3 is better than standard SLS materials by a factor of at least 3.

Wear test, swivelling CF53: v = 0.01 m/s; ß = 60°

Y = Wear rate [μm/km]

A = iglidur® I3-PL (SLS) B = iglidur® I180-PF (FDM) C = iglidur® G injected D = iglidur® W300 injected

Test results:

In the heavy-load tests shown here, wear rates similar to those of iglidur® injection-moulded bearings were achieved with a load of up to 45 MPa (= 1600 kg) on the printed iglidur® I3 bearings.

Flexural strength dependent on construction direction

Y = flexural strength [MPa]

A = Construction direction flat (Z-axis) or lateral (Y-axis) B = Construction direction upright (X-axis)

Test results:

The bending tests indicate the greater strength of iglidur® I3 and particularly the more uniform strength irrespective of the construction direction.

More motion plastics® for 3D printing

3D printed Tribo filaments

Made for motion

Our tribologically optimised filaments are up to 50 times more abrasion-resistant than standard 3D print materials. This results in higher levels of effectiveness. So you can produce prototypes and small series more quickly and cost effectively. Printed components can also quickly replace wear parts and reduce downtime periods.

3D printing service
