High flexibility
3D printing

Highly flexible rubber-like materials that have elongation at break greater than 50%.

SLS High flexibility 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

FDM High flexibility 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.
