iglide® I3-PL for 3D printing via SLS

SLS material  

The material iglide® 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

Wear test, rotating

Y = Wear rate [μm/km]
 
A = PA12 (SLS)   B = PA12 + glass balls (SLS)   C = iglide® I3-PL (SLS)   D = iglide® I180-PF (FDM)

 
Shafts  
Test results:

In this rotating wear test, the abrasion resistance of iglide® 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 iglide® 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

Linear wear test

Y = Wear rate [μm/km]
 
A = PA12 (SLS)   B = PA12 + glass balls (SLS)   C = iglide® I3-PL (SLS)   D = iglide® I180-PF (FDM)

 
Test results:

The results shown here from the linear short stroke test, indicate that the wear-resistance of iglide® 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°

Wear test, swivelling

Y = Wear rate [μm/km]
 
A = iglide® I3-PL (SLS)   B = iglide® I180-PF (FDM)   C = iglide® G injected   D = iglide® L280 injected

 
Test results:

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

Flexural strength dependent on construction direction

Flexural strength

Y = flexural strength [MPa]
 
A = Construction direction flat (Z-axis) or lateral (Y-axis)   B = Construction direction upright (X-axis)

 
Construction direction XY  
Test results:

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