Assessing the Impact of Top-Up Powder Reuse Strategy on MS1 Powder Characteristics and L-PBF Printed Part Properties

Metals
In additive manufacturing, particularly with Laser–Powder-Bed Fusion (L-PBF), augmenting recycled powder with virgin powder is common to extend lifespan. This practice complicates tracking recycling cycles, as parts consist of layers from both virgin and
