Talking Points

Recent interactions between the hosts and their guests.

When Production Overtakes Prototyping: Materialise’s Next Phase of AM
Q: What does that milestone tell you about the evolution of additive manufacturing from where you guys started and where you are today?
He says the milestone reflects both more demand for serial production and the growing in-house prototyping capabilities of customers. Low-cost printers with improving quality are making engineering prototypes easier to produce internally, while demand for production parts is growing in both metal and polymer additive manufacturing.
When Production Overtakes Prototyping: Materialise’s Next Phase of AM
Q: How did you actually get into additive manufacturing back then?
As a master's student at the University of Leuven, he encountered a paper on stereolithography. His thesis adviser later invited him to help establish research in the field as Materialise was being founded.
Why AM and Orthotics & Prosthetics are the Perfect Fit
Q: Can you tell us a little bit about the conventional manufacturing process and how it differs from additive manufacturing?
The conventional process is highly hands-on and involves casts, plaster or fiberglass molds, manual shaping, and multiple material steps that are time-consuming and lack a consistent record. Additive manufacturing introduces digitization, direct scanning, and the ability to capture and reuse digital molds, enabling more repeatable fits, better documentation, and the potential to tailor dynamics and materials to individual patients.
Inside GM's Additive Industrialization Center with Ante Lausic
Q: How does GM's Additive Industrialization Center interact with suppliers and the rest of GM to enable mass production?
GM uses the AIC as a manufacturing readiness and education hub, testing processes, materials, and parameters in-house to de-risk adoption before suppliers scale. It acts as a bridge between internal design/engineering and supplier networks, sharing learnings, setting expectations, and advising on design and process parameters while avoiding over-specifying golden builds, so suppliers can innovate within automotive standards and PPAP requirements.
Inside GM's Additive Industrialization Center with Ante Lausic
Q: What needs to be true for additive manufacturing to truly scale in the automotive sector?
The key constraints are volume, material availability, and total part cost. AM must show a compelling, vehicle-wide value beyond novelty, using automotive-grade materials, reliable supply chains, and feasible tooling/integration with existing production systems, while also delivering predictable quality and manageable post-processing. In essence, scalable AM requires the right materials, machines, processes, and a mature supply base aligned to automotive needs.
