Advantages of the 3D printer Alfa-280

Open platform
postprocessor settings are as open as possible to unlimited experiments with parameters and printing modes to achieve the required quality indicators
Excellent productivity and stability
owing to the use of a single-mode ytterbium laser with continuous radiation and water cooling from a leading European manufacturer;
Laser beam focus diameter
in the range from 75 to 200 μm enables considerable expansion of the operational parameters of printing for achieving required productivity and products quality
The build chamber is completely hermetic
with the optional possibility of both preparation of the printing process and then unpacking of finished products without any use of additional personal protective equipment
Filter regeneration system
automatically performs the procedure of self-cleaning of filtering elements
Metal powder feeding system
continuously, with precise dosing during the printing process
Using a wide range of metal powders
stainless and heat-resistant steels, Inconel 625 and Inconel 718, aluminum, titanium, cobalt-chromium and other alloys
Built-in industrial video camera
with the GigE interface and CMOS sensor for continuous monitoring of the building process and archiving of data with high-resolution images
Delivery set
pre-installed software, vacuum powder removal unit of the model APR-042, automated metal powder sieving unit of the model APS-052, with which it is possible to start the process of 3D printing immediately

Powder Bed Fusion

Powder Bed Fusion is an innovative technology for manufacturing geometrically complex products by application of the powder, layer after layer, and local melting of selected areas of each layer of the powders of various metal alloys to form a shape presented as a CAD model. As the source of energy, a high-power ytterbium fiber laser of continuous radiation is used. This process is successfully ousting out traditional manufacturing methods, as physical and mechanical properties of products manufactured with it, as well as their geometry, surpass those of analogs manufactured with traditional technologies
