Powder bed fusion with a laser beam for metals (PBF-LB\/M) has reached high maturity, enabling decentralized, on-demand production of high-performance components that helps mitigate supply chain disruptions.\u003c\/p\u003e\u003cp\u003eA key advantage of PBF-LB\/M is its exceptional design freedom, enabling the tool-less fabrication of complex geometries-such as topology-optimized lightweight designs or patient-specific medical implants-that cannot be realized with conventional methods. This reduces manufacturing steps and material waste, making it widely used in aerospace and medical technology.\u003c\/p\u003e\u003cp\u003eDespite these advantages, PBF-LB\/M faces significant challenges in quality, time efficiency, and cost-effectiveness. Long process times lead to high production costs, limiting competitiveness at high volumes. Increasing productivity without compromising quality is essential for broader industrialization.\u003c\/p\u003e\u003cp\u003eThis work optimizes the theoretical build rate for AlSi10Mg using a ring-shaped laser intensity distribution combined with high laser power. The optimized process achieved a 233% increase in build rate-from 10.8 mm³\/s to 36 mm³\/s-compared to a Gaussian reference process at 370 W. Economic analysis on an EOS M290 with 60 µm layer thickness revealed a maximum reduction of\u003c70% in process time and cost, with realistic savings of 50\u002665% under optimal conditions.\u003c\/p\u003e","brand":"None","offers":[{"title":"Couverture souple","offer_id":46827044077778,"sku":"9783032289421","price":233.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/8980\/5233\/files\/1_c1d9c5c4-a71f-49fc-9314-360dcc8e0933.jpg?v=1778515461","url":"https:\/\/www.indigo.ca\/fr\/products\/analysis-and-method-to-increase-the-productivity-of-laser-based-powder-bed-fusion-of-metals","provider":"Indigo","version":"1.0","type":"link"}
