FAQ
What is metal 3D printing / metal printing?
Metal 3D printing is an innovative printing technology that is based on additive manufacturing processes and enables high precision. By using metal powder as the starting material, complex metal parts with optimized properties are created. Various printing processes such as SLM, DMLS, EBM and binder jetting use lasers or a binder to bond powder layers in a targeted manner. Manufacturers benefit from the flexibility of this technology, as components with different geometries, cavities and support structures can be produced. These printing processes are used particularly in the aerospace and automotive industries. The process begins with the creation of a digital 3D model of the object, which is then converted into a file format that can be read by the metal 3D printer. The printer then uses a laser or electron beam to melt and join the powder layer by layer until the final object is complete.
Advantages of metal 3D printing
There are many benefits to using metal 3D printing for industrial manufacturing, including:
- High precision and accuracy: Metal 3D printing enables the creation of molded parts with challenging geometry and tight tolerances that would be difficult or impossible to produce using traditional manufacturing methods.
- Cost-effectiveness: Metal 3D printing reduces the need for expensive tooling and molds, making it a cost-effective option for smaller production runs or prototypes.
- Flexibility: Metal 3D printing can be used to produce a wide range of parts, from aerospace and medical components to jewelry and art.
Important printing processes in metal 3D printing
In selective laser melting (SLM) and direct metal laser sintering (DMLS), metal powder is melted by a laser and built up layer by layer on the build platform. Alternatively, binder jetting uses a liquid binder to bond powder particles before a sintering process follows. Laser cladding or FDM-based processes with metal filaments are also used for industrial applications. The use of materials such as stainless steel, aluminum or copper enables components with high strength and stability.
Applications of metal 3D printing
The choice of the right printing process depends on the desired stability, geometry and use of the workpiece. While selective laser melting is particularly suitable for complex industrial applications, binder jetting and FDM enable more cost-effective solutions with flexible materials. Metal printing is increasingly being optimized to make production more precise, efficient and sustainable. The combination of modern printers, innovative manufacturing processes and high-performance materials makes this technology a key innovation in industrial production.
Industries that use metal 3D printing:
- Aerospace: production of lightweight and stable components with high strength.
- Automotive industry: prototypes and special parts with complex geometries.
- Medical technology: Individual implants and medical workpieces.
- Toolmaking: High-precision tools and molds.
- Electronics industry: Components with high conductivity, e.g. made of copper.
