    Selective laser melting

    Principle of operation

    Selective laser melting is a metal additive manufacturing process in which the material is melted in a pre-formed layer. The scanning device fuses metal powder particles with a laser, bonding them together and growing the product layer by layer.

    Advanced Optics

    Now the optical system allows us to achieve uniform heat distribution over the entire area of the laser spot. As a result, we obtain products with less porosity and lower internal stresses due to the uniform fusion of metal powder. In addition, the scanning device has the ability to move along the Y axis, which means we can change the diameter of the laser beam from 60 to 120 microns.

    The increased energy efficiency of laser fusion is achieved through a special optical element that converts a standard Gaussian beam of laser radiation (with a peak at the center of the beam) into a distributed beam (with an average value at the center and with increased power around the spot ring). Due to this solution, the efficiency of energy input into metal powder increases by 20-30%.

    Available options

    Hydrogen sensor

    Thermal imager (ensuring control of temperature fields of material fusion)

    Machine vision system (ensuring control of the uniformity of the powder layer on the construction platform)

    Pre-evacuation of the chamber before the printing process

    Glove boxes

    Allow the operator to begin safe work with the product after printing is completed, eliminating the harmful effects of metal microparticles on the organs of vision and breathing. Glove ports are also needed to prevent titanium or aluminum powder from igniting when in contact with oxygen.

    Laminar flows

    Laminar flow of inert gas, ensuring the removal of unfused powder particles and combustion products from the growing zone.

    Build Zone Reducer

    Ideal solution for universities and enterprises that conduct research and development work with new materials when the quantity of powder is limited. The reducer is installed in the construction well and transforms the construction zone from 250 mm into an area with a diameter of 70 mm and a height of 80 mm. Installation/removal of the reducer takes up to two hours.

    Pedal assembly

    While the operator's hands are in the glove ports. The pedal assembly is designed to raise and lower the construction platform and turn on the vacuum cleaner

    Powder bins

    When developing a 3D printer, we paid special attention to ease of use. By distributing the entire volume of powder that comes from the printing process into four small bins. For convenience, circular holders are made. The filling of the bins is controlled by scales.
