3D Aluminum Printing Service: 2025 Service-Provider Masterclass
Executive Summary Global aluminum additive revenues are projected to exceed USD 4.8 B by 2027 driven by WAAM’s 18 USD/kg cost and SLM’s 0.05 mm tolerance. This guide delivers 2025 cost tables, quality matrices, and three brand-new case studies, no recycled charts, so service providers capture 65 % gross margins and 24-hour global delivery windows.
