Prima Power Laserdyne, Champlin, Minnesota, USA, has introduced a new hybrid Additive Manufacturing machine which combines Directed Energy Deposition (DED) Additive Manufacturing, welding, drilling and cutting capabilities. The Laserdyne 811® serves as a replacement machine for the discontinued and obsolete Laserdyne® 780.
The Laserdyne 811 is said to employ the most current hardware and software components for flexible precision laser processing in an affordable compact platform. The combination of workstation, controller and laser in one machine is said to offer a cost-effective, high-speed, reliable solution for low and high throughput manufacturing, and takes full advantage of fibre laser technology.
The machine is said to have the necessary flexibility and precision to perform optimised laser processing on welding, drilling, cutting, and DED AM applications for small- to medium-size workpieces. Its working envelope is 1100 x 800 x 600 mm (41.5 x 31.5 x 24 in) for the X, Y, and Z axes, respectively. Each axis offers 50 m/sec velocity and acceleration of 1.2 g and is reportedly optimised for floor space efficiency.
When used for DED applications, the Laserdyne 811 is said to offer precise real-time control over powder deposition, laser power and shield gas delivery, enabling powders to be fused for the production of parts from scratch or to repair and rebuild metal surfaces, which are then machined to the OEM’s specifications.
The Laserdyne 811 is designed to take advantage of the company’s BeamDirector® technology. An additional two axes of motion (C and D) provide access to hard-to-reach places in the workpiece, precise beam placement, and a high degree of flexibility. The BeamDirector has 90 rpm rotational speed and control repeatability of 15 arcsecs. In addition, it supports laser processing from 90° (normal to the surface) to 10° off the surface of a part all the way along the axis of travel.
As with all Prima Power Laserdyne machines, the Laserdyne 811 is reportedly equipped with the latest standard software and supports Windows 10. This includes the full suite of SmartTechniques software to optimise the laser process and shorten cycle times, while improving process quality and consistency. The machine is also said to support the implementation of Industry 4.0 through the use of MTConnectTM real-time parameter and data streaming along with Prima Power Laserdyne developed SPC process data reporting and storage capability.
FastTrim and Fast Suite II CAD/CAM software, which support full six-axis interpolation, are also optionally available with the Laserdyne 811. The CAD/CAM option offered with the DED Additive Manufacturing machine is AMExpress, with CAM manufacturing software to produce part programmes.
