Fibre reinforcement

Combining strength and aesthetics

The true challenge for prototype materials lies in the comparison with the “real thing”. You want your large models to follow the shape of your design perfectly and be as robust as your production parts. Combining Mammoth Stereolithography with fiber reinforcement is the fastest way to answer this need.

"A stereolithography race car body that can survive 140km/h on a race track without damage? Most would say, “not likely”. Actually this is exactly what was achieved with the Areion by Formula Group T: going from initial shell design to a 3D printed car body in just 3 weeks. Thanks to the glass fiber reinforcement the car body shows strengths similar to production materials."

Jurgen Laudus, director Materialise AMS
Stereolithography parts with glass-fiber backing are ideal for functional prototyping of large plastic components. The large reinforced stereolithography parts show strength similar to, and even beyond Laser Sintered parts, while their aesthetic finish is superior. Better yet: their properties can be compared to those of production materials such as ABS.

Reinforced Stereolithography versus Laser Sintering

Compared with Laser Sintering parts, the reinforced stereolithography behaved much better and yielded significantly less when loads were applied. Both aspects are crucial for larger prototypes. But the main advantage of strong stereolithography elements over the sintered alternative is aesthetic: the A-face of these prototypes can be finished to meet even the highest expectations.

Mammoth Stereolithography and Fiber Reinforcement: a unique combination

With their patented Mammoth Stereolithography machines, Materialise can build components with dimension up to 2100mm x 700mm x 800mm. Parts built on these machines are the ideal base for a perfectly finished A-face and a B-face that can be reinforced with glass- or carbon fiber. Additionally, click boxes, mounting elements, and other functional details can be 3D Printed in Laser Sintering or FDM and be included in the backing. Let Materialise take care of the full process: from file preparation to fully finished prototype.
