The Technical University of Darmstadt contacted Liqcreate in 2020 with a question regarding compression strength of 3D-printed resin. The Institute for Printing Machines and Printing Processes at TU Darmstadt was looking into 3D-printed equipment for regular printing processes. The goal was to find a hard, abrasion resistant resin with high compression strength to be used in their 2D printing process development.
It is well known that thermosetting resins (which most 3D-printing resins are) have higher compression strength compared to their thermoplastic counterpart. After selecting the three rigid resins Liqcreate Deep Blue, Strong-X and Composite-X, sampling and testing started.
Results of 3D-printed resin compression test
All selected resins were measured without curing (uncured) and with their advised post-curing protocol.
The rigid resins Strong-X and Deep Blue performed similar with a compression strength of around 68 to 72 MPa. The ceramic reinforced Composite-X outperformed all other resins with an impressive 158 MPa compression strength.
