Materials for different 3D printing techniques

The IROPRINT additive manufacturing platform uses polyurethane (PU) and thermoplastic polyurethane (TPU) materials designed to address the need for flexible and elastic yet hard-wearing materials for 3D printing applications.

Polyurethane (PU) materials

PU systems provide a unique combination of tensile strength and elongation, allowing user to produce high performance elastomeric end-products.

The materials are generally reacted using an external activation source (heat, radiation) or the blending of components that can be used in a variety of production methods (casting, injecting, coating, …).

The end result is a tough crosslinked network with increased resistance to several chemicals. With the introduction of our IROPRINT™ R grades we now have 1K PU systems that can be used in radiation curing (UV, visible) additive manufacturing techniques.


  • Stereolithography (SLA)
  • Digital Light Processing (DLP)

Thermoplastic Polyurethane (TPU) materials

TPU is a unique and extremely versatile category of elastomer. It is renowned for many things including its: high elongation and tensile strength; its elasticity; and to varying degrees, its ability to resist oil, grease, solvents, chemicals and abrasion. These characteristics make TPU very useful across many markets and applications.

Inherently flexible, it can be extruded, or injection molded on conventional thermoplastic manufacturing equipment to create solid components typically for footwear and many others such as cable & wire, hose & tube, film & sheet etc.


  • High Speed Sintering (HSS)
  • Selective Laser Sintering (SLS)
  • Fused Filament Fabrication (FFF)
