Laser Metal Deposition Machine Uses Blue Laser
The blue wavelength laser is said to increase process speeds and work with more materials than industry-standard infrared lasers.
Formalloy has released its L-series laser metal deposition machine with an inert gas build chamber, scientific monitoring capability and a blue wavelength laser. It can be used to 3D print, repair and clad metallic parts in a range of materials with speed and accuracy, the company says. The first machine of this type is complete and is slated to be installed at University of California - San Diego's Department of Nanotechnology.
Blue lasers can process materials that infrared lasers cannot process or can only process in low yields. The absorption of the L-series machine’s blue laser is said to be between 3 and 20 times better than the industry-standard infrared wavelength, resulting in process speeds that are between 2 and 10 times faster. The spot size of the laser is 5 times smaller than infrared lasers for precision, resolution and high finish quality.
Finishing 3D-printed parts requires different considerations than conventionally machined ones. One expert offers tips.
Analyzing directed energy deposition and powder-bed fusion provides a thorough understanding of the extra machining necessary for a “near net shape” versus a “net shape” manufacturing process.
A new metal AM system for batches of end-use parts was designed to permit productivity and machine pricing comparable to a CNC machine tool.
