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

No support material required
Excellent mechanical properties
Can produce complex geometries

Higher cost than FDM
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

Fine features & high detail
Smooth, injection mold-like, surface finish

Support marks may be visible on surface
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

Low-cost
Fast turnaround times

Limited dimensional accuracy
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

Multi-material capabillities
No support marks visible on surface
Smooth, injection molding-like finish

Higher cost than SLA/DLP
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.
