Evaluation of Digital Metal's manufacturing capabilities by the Technical University of Denmark.
We would like to introduce the excellent hole processing capabilities of Digital Metal. As an example of an application with holes, we recommend nozzles.
This paper introduces the 3D printing capabilities of the Technical University of Denmark. The paper states that when creating channels (internal flow paths or holes), L-PBF may lead to shape and surface deviations at overhangs due to the formation of dross (from molten metal), while binder jetting (BJ), which does not melt powder particles during the process, may have the potential to overcome this issue. Characterization of channels made by laser powder bed fusion and binder, 2020-07-15 Authors: T. Dahmen* et al. * Technical University of Denmark Paper Summary: - Stainless steel test specimens were created with holes of 2mm diameter at angles from 0 to 90 degrees in 15-degree increments. - The comparison included two types of L-PBF and two types of BJ, including Digital Metal. - BJ achieved high precision and surface quality regardless of hole angle compared to L-PBF. - The precision of Digital Metal corresponds to ISO IT13-14 (equivalent to drilling, die casting, and forging).
