Until recently, the additive manufacturing industry focused heavily on innovation. The continuous introduction of radical new technologies often led to hesitation among manufacturers, who were reluctant to invest in refining and optimizing existing applications while anticipating the‘ next big thing’. As a result, many delayed new investments, uncertain of where the industry was headed. Now, a shift is occurring. A period of‘ détente’ in the technological arms race is allowing manufacturers to confidently invest in scaling production, driving broader adoption, and fully realizing the benefits of additive manufacturing. This shift is evident in the fact that fewer companies are entering the space, yet existing manufacturers are expanding their machine fleets. This marks a transition from innovation to application and signals a readiness to scale the technologies and processes already in development. Scaling in additive manufacturing presents unique challenges, from material costs to process repeatability and production speed. Yet, scaling is essential for enabling cost-effective mass production while maintaining quality and design flexibility. Addressing these challenges is crucial for additive manufacturing to establish itself as a key pillar of modern manufacturing.

Scaling up in additive manufacturing( AM) directly relates to economies of scale, particularly in the relationship between raw material volumes and cost per kilogram. Despite 35 years of progress in additive manufacturing, material costs remain a major hurdle. While prices have decreased over time, they still cannot compete with the raw materials used in traditional manufacturing. The premium price for additive materials is largely due to their specialized forms, such as powders. While further price reductions are possible, the current market volume is not yet sufficient to drive down costs significantly. This creates a classic chickenand-egg scenario: manufacturers need lower material costs to scale production, but costs will only decrease when production volumes rise significantly.
