Oscar Lovera, COO at Xometry, explains how the AI-powered manufacturing marketplace is digitizing the sourcing of custom parts by integrating design, quoting, and manufacturability feedback into a single workflow. He discusses the shift from traditional, disconnected RFQ processes to instant, scalable matching between engineers and a global network of manufacturers, including CNC, 3D printing, and injection molding partners. Lovera emphasizes that while AI automates repetitive tasks, human expertise remains critical for complex problem-solving, trust-building, and ensuring operational excellence, arguing that strong processes matter more than flashy equipment. He also shares his perspective on supply chain resilience, advocating for global flexibility over local sourcing and highlighting the importance of intentional career choices for future engineers.
