Description:

Additive machine for making metal articles from metal powders by the layerwise laser melting (SLS) is a 3d printer for metal. It is allowed to use metal powders of spherical shape, made of alloys of titanium, stainless steel and alloy steel, copper and aluminum with an average median diameter of 20÷25 microns.

Additive the machine is made in the form of a modular design or a single module design.

 


Advantages:

– compact,

relatively low cost,

– high level of automation.

 

Description of modular additive machines:

Modular additive machine is made in the form of a modular design. The composition of the modules: the module of preparation of the powder, the module for building products (the production module) and remote control.

The module of preparation of powder intended for the collection of powder in the hopper, the drive, feeding it into the module build, return from the working area of the module building at the end of the build process, separation of powder and return it to the silo storage.

In the building products installed: hopper mechanism of the dosed supply of the powder, the mechanism of formation of a given layer of powder, 3-axis optic-laser system, preparation system, gas exchange and quality control of inert atmosphere Cabinet pneumatic system and electric Cabinet.

Control the whole process of preparation and build of the product is equipped with high performance computer with the information output to the monitor.

This arrangement of the machine allows you to:

without changing the provisioning of the powder to change the module build for specific tasks. For example, to use the same module of preparation of powder for different machines depending on the type of the powder,

have multiple renderers powder (for different powders) in a single module build

to buy only the module build without the module the preparation of the powder and sprinkle the powder manually to separate into a separate separator, etc.

All operations have a modular additive machines automated. Manually is once the download of powder from shipping containers to the receiving chamber and cleaning products and machines from powder after the end of the build process (vacuum cleaner). The powder from the vacuum cleaner immediately gets on the separation of the module of preparation of the powder and further into silo storage.

Seizure of the product after the build is done lifting mechanism through a window in the upper part of the module build.

Description single-module additive machines:

Single-module additive machine has a single module design. Inside the module located in the area of building products, Cabinet pneumatic, the electric Cabinet, the system of training of the inert medium, gas exchange, cleaning and cooling the inert gas, the system of control over the building process and 3-axis fiber-laser system.

Area of building is equipped with a silo powder with a dosing mechanism, a mechanism of formation of a given layer of powder, the removable hopper for collecting waste powder, a video camera for visualizing the build process of the product and display the image on the monitor screen of the control panel.
