Rubber-like
3D printing

Materials with Shore Hardness below 70A that produce parts with a rubber-like feel.

SLS Rubber-like Materials

SLS is used for both prototyping and small-batch production of functional plastic parts with good mechanical properties.

Benefits and Limitations

Can produce complex geometries

Longer lead times than FDM

Characteristics

Price $$$$$ Tolerance ± 0.3% (min: ± 0.3 mm)
Turnaround time < 5 days Wall thickness 0.7 mm
Max part size 75 x 55 x 55 cm Layer height 80 - 120 μm

Standard TPU

TPU (SLS) is an elastomer with good tear resistance and shore hardness of 45D that is suitable for durable parts with rubber-like properties.

Material family

SLA/DLP Rubber-like Materials

SLA is most suitable for visual applications where an injection mold-like, smooth surface finish, and a high level of feature detail are required.

Benefits and Limitations

Smooth, injection mold-like, surface finish

Brittle, not recommended for functional parts

Characteristics

Price $$$$$ Tolerance ± 0.5% (min: ± 0.1 mm)
Turnaround time < 2 days Wall thickness 0.5 mm
Max part size 150 x 75 x 50 cm Layer height 25 - 100 μm

Rubber-like resin

Rubber-like resin (SLA/DLP) produces parts with a rubber-like feel and shore hardness < 70A that can be compressed and bent. Lacks the performance of true rubber.

Material family

FDM Rubber-like Materials

FDM is the most widely available 3D printing process, mainly used for low-cost prototyping and design verification with very fast turn around times.

Benefits and Limitations

Fast turnaround times

Print layers are likely to be visible

Characteristics

Price $$$$$ Tolerance ± 0.5% (min: ± 0.5 mm)
Turnaround time < 2 days Wall thickness 0.8 mm
Max part size 100 x 100 x 100 cm Layer height 50 - 400 μm

Standard TPU

TPU (FDM) is a rubber-like, flexible elastomer with shore hardness 60A - 95A that can bend and compress. Lacks the performance of true rubber.

Material family

Material Jetting Rubber-like Materials

Material Jetting produces parts of the highest dimensional accuracy with very smooth surface finish, used for both visual prototypes and tooling manufacturing.

Benefits and Limitations

Smooth, injection molding-like finish

Brittle, not recomemended for functional parts

Characteristics

Price $$$$$ Tolerance ± 0.1% (min: ± 0.05 mm)
Turnaround time < 5 days Wall thickness 1.0 mm
Max part size 100 x 80 x 50 cm Layer height 16 - 32 μm

Rubber-like resin

Rubber-like resin (Material Jetting) produces high-detail parts with a soft rubber-like appearance and shore hardness < 70A. Not suitable for functional prototypes.
