3D printing is an additive manufacturing process used to produce complex and accurate components by building parts layer by layer from digital CAD data. Instead of removing material like CNC machining, 3D printing forms parts directly from plastic or metal powders, filaments, or resins, enabling intricate geometries, internal features, and rapid iteration for both prototypes and production parts.
A 3D printer builds parts layer by layer from digital instructions, forming precise geometries by bonding each layer to the previous one.
A 3D CAD file is sliced into layers and converted into machine instructions that guide the printing process.
Different technologies are used based on material and application needs, from plastic prototyping to metal production parts.
We provide a range of advanced plastic and metal 3D printing technologies to support rapid prototyping and production-grade parts. Each process is selected based on material requirements, part complexity, accuracy, and end-use performance.
We offer a broad selection of plastic and metal materials for 3D printing, supporting prototypes through production-ready parts with consistent quality and performance.
