MetalMaker 3D is a US/EU based advanced manufacturing startup that offers the MetalMaker System, a unique solution for producing custom metal parts by combining additive manufacturing, AI software, and industrial metal casting. Their system produces metal parts with the properties of industrial castings, featuring isotropic mechanical performance, high precision with uniform shrinkage, and affordability by using standard casting alloys instead of expensive metal powders. The modular system supports scalable production from prototyping to volume manufacturing with high throughput, making it a capital-efficient alternative to traditional metal 3D printers. The company has venture capital backing from Techstars and Stanley Black & Decker, positioning it as an innovative player in the metal parts manufacturing market.
