Weibu 3D SLM250 industrial grade metal 3D printer

1. Main parameters:

★Laser optical system: imported single-mode fiber laser, laser power: ≥200W, output power range: 10%-100%;

Laser cooling method: water cooling, chiller requirements: water storage capacity ≥ 10L, temperature control accuracy: ± 0.1 ° C, alarm when the water level is too low or the temperature is too high, cooling power: ≥ 2.5kW;

★ Scanning galvanometer: imported high-precision scanning galvanometer, laser spot can cover the entire sintering area, including four corners,

Scanning and positioning speed: X, Y axis scanning speed: ≥ 7m / s; X, Y positioning speed: ≥ 7m / s;

Positioning accuracy: scanning angle positioning accuracy ≤ ± 4μrad; repeat positioning accuracy ≤ ± 4μrad;

★Working room molding size: ≥250mm×250mm×300mm (L, W, H; with fastening screw position);

★Inflatable atmosphere of working cabin: adopting field mirror air-leather shielding protection, linear guide and active cleaning of observation window, etc., can simultaneously remove black smoke and oxidized slag generated during the forming process, keep the paving plane clean and ensure activity The metal powder is not oxidized. The inert gas flow and pressure input into the work chamber can be monitored and adjusted in real time;

★Working room sealing requirements: using a floating balance force elastic sealing device, 50 mbar positive pressure sealed working compartment, high-reliability sealing such as disturbance rapid oxygen discharge;

Inert gas consumption: less than 0.6m3/h during molding;

★Powdering device: It adopts active cleaning type powder-scraping device, adopts one-way dynamic intelligent powder laying method, and is equipped with at least two different materials for spreading powder scraper (high-speed steel, silicone rubber, etc.), according to the material of the parts and The shape is selected by a suitable scraper to achieve the best molding effect;

★ Thickness of paving layer: adjustable within 20μm ~ 80μm;

★ Oxygen analysis alarm function: The working chamber is equipped with an oxygen analyzer, and the test accuracy is 100ppm. During the processing, when the oxygen content in the working chamber rises to an abnormal level, the device has a photoacoustic alarm prompt function and stops processing. When the oxygen content drops to a certain value again, the processing can be continued after confirmation, thereby eliminating the processing process. The risk of explosion of the active metal powder and the quality of the processed parts;

Oxygen content in the working room: less than 1000ppm within 30min after starting the equipment;

★Independently developed control software that supports the following functions: During the forming process, the computer displays the current molding cycle progress (total height of the molding, total number of layers, current processing layer, processing time, start processing time, processed time), molding The required powder height, real-time display of oxygen content in the forming chamber, part temperature and other parameters, the forming process parameters can be modified as needed, the processing can be suspended, processing continues, the single-layer powder supply can be adjusted in real time, automatic control and manual control can Switching, when the automatic control fails, manual control can be performed at the standstill of the forming program, and the product is continuously formed according to the previously set program;

★Special functions: open core forming process parameters (laser power, scanning speed, scanning pitch, lap ratio, etc.), and can individually set and control the parameters of each machined part, with self-diagnosis function, can be used for the running process Various faults are alarmed in real time by sound and light;

Safety system: The equipment should have an emergency stop button, and the laser will stop running immediately after pressing;

★Smoke filter system: The filter system has an automatic cleaning component, which can automatically clean the filter element, which can achieve a filtration accuracy of 0.1μm and a discharge level of H13;

★ molding materials: stainless steel, die steel, cobalt chromium molybdenum, titanium alloy, aluminum alloy, copper alloy, high temperature nickel-based alloy powder, etc.;

Working requirements: power supply: power ≤ 9kW, requiring equipment to work stably for 24 hours in a working environment with an ambient temperature of 10 to 30 ° C and a relative humidity of ≤ 85%;
