Material Testing of 2PP 3D-Printed Parts

First Standardized Material Testing of 2PP 3D-Printed Parts

UpNano printers and resins for macroscopic test specimens. Superior properties compared to conventional resin-based 3D printing.

Vienna, Austria, 22 February 2024 – For the first time, mechanical properties of 2PP 3D-fabricated bulk specimens in the mm to cm range have been tested using established standardized methods. This breakthrough was made possible by combining the use of the fastest commercially available 2PP 3D-printer (NanoOne) with resins that can be processed at very high volumetric build rates, enabling upscaling. The test results, now published in “Advanced Materials”, demonstrate the superior material quality of the UpPhoto and UpDraft resins compared to an acrylate resin (ETA/TTA). In addition, both materials are fully cured immediately after printing, eliminating the need for post-treatment. A multinational collaboration involving researchers from Technical University Vienna (TU Wien), California Institute of Technology (Caltech) and the RWTH Aachen University, along with materials experts from UpNano GmbH conducted the comprehensive study.
