igus builds 3D printer for high temp filaments

igus followed up on their concept of Low Cost
Automation at their factory by building a new HT-3D printer for the development
of high-temperature filaments using in-house mechanical engineering components.

Complete linear systems consisting of drylin W linear
guides, dryspin lead screws made of stainless steel and the igus standard
stepper motors were used. Thanks to the new 3D printer, users can now use a
lubrication-free and maintenance-free filament for the production of
heat-resistant special parts with the iglidur J350 high-performance plastic,
available from Treotham.

“A good example of our Low Cost Automation
concept,” says Tom Krause, igus GmbH, about his team’s newly designed and
constructed high-temperature 3D printer.

High temperatures create problems not only for many
machine elements in plants but also conventional 3D printers. In order to develop
new filaments for wear-resistant parts in high-temperature applications, igus
has now built a high-temperature 3D printer. For the mechanical system, igus
engineers relied on heat-resistant stainless steel components of the
maintenance-free drylin W linear guide and smooth-running dryspin high helix
lead screws in the X, Y and Z axes. Lubrication-free liners and lead screw nuts
made from the wear-resistant high-performance plastics iglidur X and iglidur
C500 ensure precise adjustment of the building board, even with installation
space temperatures of up to 200¡C.

“In the new 3D printer, we rely on standard
components from igus, which work reliably even with the high installation space
temperatures. We use a nozzle that can melt the filament at a temperature of up
to 400¡C,” explains Tom Krause, Head of Additive Manufacturing Business
Unit at igus GmbH. “Thus we were able to develop and extensively test a
new filament for high-temperature environments with iglidur J350.”

Wear-resistant
parts suited for up to 180 degree Celsius

The lubrication-free iglidur J350 material is already
offered by Treotham in the plain bearing and bar stock range. The
high-performance plastic is characterised above all by its extremely high wear
resistance and low coefficients of friction on steel. The endurance runner is
particularly suitable for rotation and has a high dimensional stability at
temperatures up to 180¡C. Medium to high loads are no problem for the iglidur
J350.

Using the high-temperature 3D printer, the filament
can be processed well on a printing plate equipped with a PET film. Typical
application areas of the new filament can be found, for example, in the fields
of vending machine technology, automotive, glass and mechanical engineering. In
addition to iglidur J350, six more igus filaments are available from Treotham
ranging from materials approved for food contact up to chemical-grade
materials. The new iglidur J350 filament can be ordered directly from Treotham
Automation.
