Laser Metal Deposition (LMD) 3D Printing Technology Knowledge - Wire Print Resolution

Even with wire, the Additec deposition system has a very good print resolution. In fact, depending on the process parameters, even the best powder print quality can be matched to the wire. When printing at high resolution, the track width is approximately 1.5 times the wire diameter, or when printing fast, the track width is approximately 2.5 times the wire diameter. The layer height can be set between 0.3x and 0.5x wire diameter. We support a wire diameter of 0.6 to 1 mm by default. Different sizes of nozzles are available upon request. Even with a small cross section, very high aspect ratio components can be printed.

In addition to the high quality achieved by wire deposition, it allows for the creation of more complex geometries about overhangs than powder deposition. Due to the high cooling rate, reliable bridging can be achieved, actually depositing material in midair.

This is a new degree of freedom in design, allowing for the creation of higher performance closed shape geometries and more efficient conformal cooling channels.

It is also possible to increase the deposition rate and printing speed at the expense of resolution. This is advantageous for parts that need to be machined before use.
