China3D printingNet November 18, aerospace supplier Premium AEROTEC and3D printingAircraft manufacturer GE Additive jointly announced that this has reached a new productivity milestone in the mass production of titanium parts for the aerospace industry.
Just last year, these partners, with the help of aerospace manufacturer Airbus, successfully verified the multi-laser titanium manufactured on the GE Additive Concept Laser M2 system, and have been working hard to increase the productivity of the machine.
Thomas Bielefeld, Project Manager of Premium AEROTEC, explained: “With this advanced technology, we are now able to achieve a homogeneous quasi-isotropic structure with excellent material properties in the overlapping area, which is not significantly different from the previous quality. Standards. At the same time, through our partner GE Additive, we have successfully increased the productivity of parts production by more than 30%.”

GE’s flagship system is equipped with two lasers measuring 250 x 250 x 350mm and 3D optics with variable spot diameters. The current 5 series machines are designed with regulated industries in mind and claim to be able to provide the accuracy, repeatability and safety required to produce such parts.
Similar multi-laser systems tend to sell at higher manufacturing speeds, but until recently, process qualifications were largely limited to parallel assembly, thus assigning its own laser to each part in the chamber. This means that a single large part usually does not benefit from the presence of a second laser.

Aviation high-volume production
Last year’s qualification overcame this limitation, as a single large part was successfully manufactured using the two lasers of the machine. The overlap area (also known as the stitched area) depends on extremely high-precision sensor calibration to succeed. Factors such as process heat must also be compensated.
Premium AEROTEC has announced plans to use a proven system to produce multi-laser components for the Airbus A320 series. The partners are now working together to further increase the speed of machine manufacturing to make industrial additive manufacturing a more attractive option for global aerospace manufacturers.
Udo Burggraf, Senior Key Account Director of GE Additives, added: “We are very pleased to reach this milestone in cooperation with Premium AEROTEC. Our success is mainly attributed to the teams of Premium AEROTEC and GE Additive, who have maintained a good track record on this project for many years. Partnership. This is not the first success, and of course it will not be the last.”
Just last month, the aerospace manufacturer Boeing passed3D printingOEM Stratasys’ Antero 800NA thermoplastic filament certified for use in flying parts. Therefore, PEKK-based polymers can now be used to additively manufacture end-use components on Boeing aircraft.
Elsewhere, the materials company Hexcel recently launched a new conductive polymer-based carbon fiber composite material specifically for use in flying aerospace parts.3D printing. HexPEKK EM meets the static management, electromagnetic (EM) shielding and radiation absorption requirements in advanced aircraft applications, making it particularly suitable for this application.
