Most metal 3D printing technologies can be divided between powder bed and powder / wire systems. In powder bed systems, the feed material used is powder-formed; a thin layer of powder is distributed over a flat surface and other parts of the surface are melted or bonded to the vertical cross-section of the final component. This cycle is repeated as many times as possible and a layer is generated with each iteration.

Powder / wire fed systems can use either metal powder or wire as feed material. The difference between the powder bed methods is that the material is continuously supplied by the printing head and melted to form a suitable shape. The most common method in this category is the Direct Metal Deposition (DMD) process.

It depends on the exact 3D printer you're using. Each of them has a maximum build volume. Typical maximum size for 3D desktop printers: 150-300 mm per side. Large prints normally take a very long time to complete, often hours or even days. Large 3D models can be split into pieces, printed and assembled into larger objects unless they fit into a specific 3D printer. Industrial 3D printers can handle much larger sizes – but they're very expensive.

DMLS is changing the way we can approach the design of the pieces. In the past, when designing a component, one would have to incorporate manufacturing considerations. There is virtually no limit on what you can manufacture using DMLS, a tool-free manufacturing approach that benefits many businesses seeking to accelerate their product development process while responding to customer demands more quickly.

While designing parts for metal printing, there are a range of design guidelines that, if followed, will help to achieve improved component quality, surface finish and dimensional accuracy. Many of these design guidelines depend on the material and laser parameters, but sticking to the geometric recommendations will help ensure that the parts turn out as planned.

The required wall thickness to ensure efficient 3D printing of most materials is 0.4 mm. Finer structures are possible, but they depend on the parameters of the paper, orientation and printer.

The average ratio between the vertical print height and the section part is 8:1 to ensure the stability of the printed part on the board.
