igus® Launches iglide® i230 3D Printing Material for High-Temperature Applications
March 7, 2024
igus® announces its new iglide® i230 3D printing material for selective laser sintering (SLS). This new powder material can withstand temperatures up to 110°C, expanding the use cases for SLS-printed polymer components
During SLS, a printer melts plastic powder layer by layer to form bearings and other components. However, parts made from standard SLS printing materials — such as PA (nylon) 12 — are generally limited to applications less than 80°C. Higher temperatures cause the material to become soft and lose dimensional stability, preventing SLS-printed components from being used in applications like automotive engines.
“As the demand for 3D-printed plain bearings for applications with high ambient temperatures has increased, we have developed a new SLS printing material called iglide i230,” says Paul Gomer, 3D Printing Material Developer at igus.
Tests performed according to DIN EN ISO 75 HDT-A and HDT-B have demonstrated iglide i230’s heat resistance. Printed parts made from the material do not deform at 80°C. They can withstand long-term exposure to temperatures of 110°C — and even short-term exposure to 170°C without deforming.
“3D-printed plain bearings made from iglide i230 have a significantly longer service life, increase the efficiency of machines, systems and vehicles and reduce the need for maintenance,” says Gomer.
At the same time, iglide i230 offers 50-percent more mechanical strength than PA 12 at room temperature. “This makes it possible, for example, to achieve the same component strength in plain bearings with a thinner wall thickness and to save room and weight in compact installation spaces,” emphasises Gomer.
Other features of iglide i230 include:
-Free of polytetrafluoroethylene (PTFE).
-Roughly 80-percent more wear-resistant than PA 12.
-Has withstood pressures of 94 MPa during bending tests.
-Protects machines and systems from electrostatic discharge.
-Does not require time-consuming relubrication work, as solid lubricants are integrated into the material to ensure low-friction, dry operation.
