Customised linear axes are 3D-printed to order

28 February, 2017

The engineering plastics specialist igus has launched a service that will 3D-print bespoke carriages and end-blocks for linear axes to customer requirements. The components are printed using a laser sintering process within 48 hours of an order being placed, using a plastic said to be three times more abrasion-resistant than conventional SLS (selective laser sintered) materials.

The printed items can be assembled with a handful of other components to produce a customised axis “within seconds”, according to igus. As well as producing axes as one-offs or in small batches, the new process will allow machine-builders to test new ideas for profile designs, stroke lengths or fastening options. The parts, printed in a high-performance tribo-SLS material called iglidur I3, can be produced in complex shapes.

“The purpose of developing the SLTI3 lead-screw unit was to enable quick and easy assembly, with the maximum possible variability,” says igus' UK dry-tech director, Robert Dumayne. “We also reduced the component count, compared to our standard SLT module, enabling it to be assembled in seconds.”

The new 3D-printing service produces customised components for linear axes, within days

The assembled axes are self-lubricating and maintenance-free. The side-mounted leadscrew configuration is available in manual or motor-powered formats.
