High Speed Additive Manufacturing and Laser Cladding
Вставка
- Опубліковано 7 тра 2022
- A new word in terms of high-speed powder materials processing by laser technologies. With recently developed EHLA (high-speed cladding technology) for surface coating, it was just a matter of time as this process found an extension into a three-dimensional world.
WIth help of specially designed high-dynamic cinematics, components can be accelerated to required feed rates with relatively little effort.
The pE3D system of ponticon, designed for maximum stiffness and dynamics, is the first to achieve the feed rates required for the EHLA process in all three spatial directions. Therefore, components with free-form and plain surfaces may now be coated, repaired, and additively manufactured utilizing a diverse material portfolio.

Fascinating process!
Great presentation!
Simply Fascinating and mind blowing
Thank you!
Double Delta. COOL!
Thank yoU!
Is this done in a vacuum? Are there any gasses trapped into the metal? Why does the surface look pitted?
No, this one is not in vacuum and there is no additional shielding gas, rather than argon, coming from nozzle - for both - shielding and powder transport.
There is no pitting. I would say it is more about powder particles, stocked on the surface, due to overspray. That might be adjusted with process parameters.
Company name?
Thats cool.. but how strong are parts compared to billet.. What the point of this if parts are substantially weaker.??
Thats very good question. We are working to find that out!
Powder will lose to the wire with process productivity
Thats a very generic statement. Strongly depends on process, its complexity. An example from high-speed world - 300 micron coating with powder flow over 200g/min for brake discs...
As for DED - www.linkedin.com/posts/arkadi-zikin_wire-powder-ded-activity-7100048870792933376-vBSI?
Powder due to micro porosity will never durable for the multi cycle stress. So this technology already are not suitable for aircraft parts manufacturing.
Laser cladding is already commonly used for repair of turbine blades. And that since decades. Powder is used as a filler material. However, i would agree with you for PBF process...
