Over the past few years, there has been a sudden surge in both the supply and demand for 3d metal printing machine.
Manufacturers have started to launch metal additive manufacturing machines that are faster, more straightforward to us, and more potent with an increasing number of compatible metals.
Many businesses are trying to adopt 3D metal printing technologies, which will help produce cost-effective metal parts and prototypes and benefit them from increased freedom of design linked to additive manufacturing. They are also suitable for various industries like aerospace, automotive, health, engineering, and more.
Main types of metal 3D printing technologies
There are generally four types of 3D metal printing technologies, which include:
- Directed Energy Deposition (DED)
- Metal filament extrusion (FFF, FDM)
- Material Jetting and Binder Jetting
- There are also resin-based 3D metal printers and metal 3D sheet lamination printers, which are very costly.
Benefits of 3D printing metal parts
- On-demand production: Metal additive manufacturing gives more flexibility and control over the production line.
- Complex designs made possible: With 3D printing technology, things become possible to create highly detailed and intricate parts that would have to be broken down into several pieces with traditional methods.
- Waste reduction: Compared to CNC milling, for example, metal AM produces less waste as it only consumes the material needed for a specific part. These are used for extrusion-based methods than it is for powder-based methods,
How does metal 3D printing work?
There are several ways to 3D print metal. Layers of metal filament deposited one after the other produce a green part that will go through debinding and sintering steps. It is also possible to fuse metal powder particles with the help of a laser or with an inkjet print head that deposits drops of binding material onto the powder.
