Direct metal laser sintering (DMLS) is an additive manufacturing technology that uses a high-powered laser to fuse fine metal powder particles together and create complex geometries. This technology is part of the powder bed fusion technology of 3D , which also includes selective laser melting and electron beam melting.
Gribbin et al. [] investigated the low-cycle fatigue behavior of Inconel 718 specimens produced via the DMLS technique.Fatigue tests under a constant mean engineering strain of 0.5% and varying strain amplitudes from 0.6%–1.4% were conducted. It was observed that the fatigue performance of the additively manufactured specimen …
Compared to ExOne's other large 3D printers for more industrial uses, the Innovent+ is a smaller and more compact machine with a smaller build volume for different applications. Rather than for large metal part , the Innovent+ is more focused on testing, teaching, and smaller-scale metal 3D , such as within universities and …
Parts made by direct metal laser sintering machines are known for their strength, hardness, and densities. ... If the DMLS® part is heat treated, its density, durability, and strength are even greater. ... Net build size: 400 x 400 x …
For other metals, the absolute minimum feature size (for positive features—those that are solid or dense) for high-resolution (HR) DMLS prints is 0.006 in. (0.1524mm), and 0.012 in. (0.3048mm) for normal resolution (NR) DMLS prints. This is …
Production of bronze–nickel parts was undertaken by solid freeform fabrication method involving direct metal laser sintering (DMLS). Sintering speed, scan spacing and hatch pattern were considered as effective process variables governing the quality of parts manufactured. ...
