AIM3D launches open multi-material pellet 3D printing system with certified high-performance polymers for prototyping and series production

AIM3D GmbH, headquartered in Rostock, Germany, has introduced its ExAM 255 and ExAM 510 pellet-based 3D printing systems, designed for open multi-material processing of certified high-performance polymers. The ExAM 255 targets rapid prototyping and material development with a compact build volume, while the ExAM 510 offers a 510 x 510 x 410 mm build chamber for small-to-medium series production. Both systems accept standard injection-molding granules — including PPS, PEEK, and glass-fiber-reinforced grades — independent of the printer manufacturer, enabling users to source materials from any supplier. AIM3D CSO Daniel Selck highlighted growing interest from US industrial sectors including automotive, aerospace, defense, medical technology, and energy, citing the company's strategy to leverage pellet extrusion for cost-efficient, scalable production with certified materials.

This launch updates the long-standing tension in polymer AM between closed, filament-based systems and open, pellet-fed architectures. AIM3D's approach directly challenges the material lock-in model dominant in FDM/FFF and SLS, where proprietary filaments or powders constrain user choice and inflate per-part costs. By accepting standard injection-molding granules — which are typically 5-10x cheaper per kilogram than filament — the ExAM series addresses a persistent barrier to serial production adoption in automotive and industrial tooling. The open material strategy also aligns with the broader industry push toward supply-chain resilience and qualification flexibility, particularly relevant for defense and medical applications where certified material traceability is mandatory. AIM3D positions itself against competitors like Pollen AM and the now-restructured Desktop Metal, but its emphasis on certified high-temperature polymers and multi-material capability gives it a distinct niche in the polymer extrusion segment.

For buyers evaluating pellet-based AM, the practical takeaway is that AIM3D has delivered a system that reduces material costs and expands sourcing options without sacrificing the ability to run certified grades needed for regulated production. The company must now demonstrate that its ExAM 510 can maintain dimensional accuracy and repeatability across multi-material builds at production volumes, and that its support removal and post-processing workflows are competitive with established polymer PBF and MJF systems. Users should verify material qualification timelines for their specific polymers before committing to production scale-up.
