The Hänssler Group uses the Ultimaker S5 3D printer to produce anti-static sealing parts


Plastics and sealing technology company Hänssler Group uses Ultimaker S5 3D printing platform and Kimya’s ABS-ESD material for the manufacture of anti-electrostatic (ESD) sealing parts.

The company additively manufactures the components at volumes of 300 per year and reported a “minimal lot-to-lot dimensional evaluation and intact ESD performance.” They have been designed to be integrated into an existing production line where they provide thermal protection between two machine components.

With an Ultimaker S5 already installed at Hänssler, the company opted for Kimya’s ABS-ESD filament due to its ESD resistance, temperature resistance up to 90 ° C and light weight. With 2.2 kg per spool, Hänssler was able to transport and handle the material more efficiently, saving time and money. Kimya will later optimize a custom print profile for Hänssler’s use of ABS-ESD on the Ultimaker S5 due to the delamination marks and flow defects that were identified after Hänssler incorporated a internal vacuum in the design of sealing parts.

Hänssler was also wary of defects in the surface of his parts, and therefore performed a high-resolution 3D scan analysis using a GOM Atos Core 3D scanner. By scanning a group of ten sample pieces, the company found that there was minimal variation from target dimensions and concluded that there was a “good level of precision and reproducibility from batch to batch. the other “.

“In addition to the ability to create precise and more complex parts with 3D printing, we also reported an 80% reduction in material waste and 60% cost per part compared to our manufacturing techniques. traditional milling, ”commented Adrian Heinrich, Marketing Director of Hänssler. “The accessibility and reliability of 3D printing and the great support from Ultimaker’s ecosystem partner, Kimya, made this project a start. “

“Ensuring high dimensional accuracy with 3D printing is essential for companies that need to assure their customers that every batch is the same and ESD-free. It doesn’t matter when, where or who prints the parts, ”added Ultimaker Technical Director Miguel Calvo. “I am proud of the close collaboration between Kimya and Ultimaker to make this happen for the Hänssler Group.
