Progress in Additive Manufacturing

In this paper, the prediction of temperature profile and melt depth for laser powder bed fusion (L-PBF) of Ti-6Al-4V titanium powder material was performed by numerically solving the heat conduction-diffusion equation using a finite difference …

Selective laser melting involves melting and solidification of metal powder particles in a track-by-track and layer-by-layer method to fabricate 3D parts. The present investigation focuses on understanding the effect of laser power and scan speed …

Additive manufacturing (AM) is as an emerging technique which can fabricate any complex shapes and is currently being used to directly manufacture end-use products. However, further progress in AM greatly relies on the advancements in materials …

Powder bed fusion is an additive manufacturing method which allows production of complex parts, in a shorter time compared to the conventional fabrication methods. During the last 60 years, Fe–Cu powders were widely used because of their …

This study analyzes a low-cost reliable real-time optical monitoring platform for fused filament fabrication-based open source 3D printing. An algorithm for reconstructing 3D images from overlapping 2D intensity measurements with relaxed camera …
