Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<p>Laser Powder Bed Fusion (LPBF) is an Additive Manufacturing technology in which a defined metal powder thickness is selectively melted with a laser, according to the geometry of the part being produced. The layer-by-layer approach allows manufacturing functional complex shaped components, with high structural integrity at low cost. This technique has been proven to produce near net-shape parts up to 99 % relative density and has viable economic benefits. However, the typical build envelope for this type of machines is of 300x350x250 mm, thus the manufacturing of large-dimension parts is unachievable. The goal of this project was to develop a customized LPBF machine with a build envelope of 1020 mm x 1020 mm x 520 mm that is able to produce high quality parts. Through fine-tuning of the processing parameters, the machine has produced samples with 316L stainless steel which exhibit relative densities above 99 %. Besides the samples, the machine has also successfully built large-dimension parts. The results obtained are a positive indicator towards the ultimate goal of zero-defect manufacturing.</p>
