DED 3D printing systems are also known as LENS (laser engineered net shaping) and DMD (direct metal deposition) machines. Directed Energy Deposition has some similarities to powder bed fusion with a couple of key differences:  DED makes use of a mounted laser with a special head that – instead of relying on a bed of powder – projects a mix of metal powder and inert gases to a specific point.   

Like PBF, the laser creates a melt pool that fuses the metal powder.  Parts can be manufactured using stainless steel, tool steel, titanium, cobalt, chrome and aluminum and a host of others. They can work with metal wire or metal powder and melting can be achieved with a plasma arc, laser, or electron beam. It’s very similar to welding so one of its primary applications is repairing and adding features to existing metal parts.


  • Metal wire is the most affordable form of metal 3D printing material
  • Some machines can work with two different metal powders to create alloys and material gradients
  • 5- and 6-axis motion enables the production of overhangs without the use of support materials
  • It’s possible to repair broken metal parts and add new components to objects
  • Large build volume
  • Efficient material usage
  • Parts have high density and good mechanical properties
  • Fast printing


  • Printed parts have poor surface quality so machining and finishing is usually necessary
  • Small details are difficult or impossible to achieve
  • High cost of machinery and operation

Laserdyne 811


The Laserdyne 811 is the latest development from Prima Additive in direct energy deposition additive manufacturing process. The machine provide precision and flexibility for a wide variety components.  It is equipped with one of the fastest laser processing systems in the industry. The controller supports 7 axes of simultaneous motion, and integrated automation to load and unload component and subassemblies, i.e. robotic, automated stock inputs, turn-table, or out feed platform.

The machine can be equipped with REAL_DED (Real-time Adaptive Laser beam for Direct Energy Deposition) laser deposition head, developed and patented by Prima Additive to increase the performance and the efficiency of the deposition process and let the end-user to adapt the laser beam spot dimensions in real-time during the process.

A single machine that supports additive, welding, drilling and cutting 3D and 2D Components. With the BeamDirector® and quick change nozzles, in a matter of a second the machine can be changed from additive, welding to drilling or to cutting. The machine can be equipped with 3 axes configuration or up to 7 axes.

Higher overall equipment efficiency due reduced downtime and maintenance. Less resources dedicated to maintaining the machines. More efficient use of floor space for the total working envelope.

The machine is designed to be equipped with an inert chamber option in order to print reactive materials such as Aluminum and Titanium. The inert chamber reaches SO ppm of oxygen concentration in all the working volume and it is possible to remove the entire building volume thanks to a pre-chamber without loose inert atmosphere inside the working chamber.

The machine encompasses over 40 years engineering and industrial laser processing expertise. The LASERDYNE® have strong reputation for consistently and quickly manufacturing quality components.
