Turning complex designs into reality in a few hours.
To support the university, local Stratasys reseller Pixel Sistemas sponsored the team and produced
FDM sacrificial molds for the students. Using a Stratasys Fortus 450mcTM 3D Printer, a mold tool for
the intake manifold was 3D printed in ST-130TM sacrificial tooling material and wrapped with carbon
fiber composite material. Once cured, the internal sacrificial core was washed away, leaving the final
composite part – a perfect process for the production of complex shapes.
“Introducing Stratasys FDM sacrificial tooling within the production process of the intake manifold
allowed us to make it from carbon fiber instead of heavier, less efficient materials,” says Aperribay. “The
superior soluble characteristic of the ST-130 material enabled a more complex shape of the intake
manifold compared to aluminum molds. The first mold for the intake manifold was 3D printed in just five
hours, as opposed to the three weeks lead time associated with conventional aluminum molds.”
The team also noted that during the curing process the material performed in high temperatures up to
121 °C and, at certain temperatures, pressures up to 620 kPa.
