3D Printers and Transport

open access: yes, 2021
3D printing (3DP) is an emerging technology associated with a more tailor-made, distributed way of manufacturing which, if successful, is bound to have repercussions on transport, supply chains, and logistics. This contribution delves into what 3DP is, how it will influence consumer wants and needs, location choices and transport resistance, and how it

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
