Problems solved by technology

At present, the mainstream 3D printer manufacturers at home and abroad adopt the automatic powder supply method. By equipping a set of automatic powder supply device, the problem of powder shortage in the production process is solved, but the working mode of a single 3D printer is still the actual production efficiency. Restricted; in addition, each 3D printer is equipped with automatic feeding equipment, which greatly increases the cost of equipment and reduces production efficiency

Embodiment

[0073] Taking a production line consisting of 5 3D printers and 1 powder supply device as an example, a laser selective melting 3D printing production line and its control method are described in detail.

[0074] (1) The production line starts. This task needs to use No. 1, No. 2, and No. 3 printers for the task, and No. 4 and No. 5 printers are in the space state. Carry out the following tests: the powder supply device detects the powder content in the material preparation cylinder through the material level sensor, and detects the oxygen content inside the device through the oxygen content sensor; No. 1, No. 2, and No. 3 3D printers detect the powder collection cylinder and the powder upper cylinder through the material level sensor The powder content in the printer, the oxygen content inside the printer is detected by the oxygen content sensor, the inert gas inlet pressure and the internal air pressure of the printer are detected by the pressure sensor, the temperature of t...

Abstract

A laser selective melting 3D printing production line system and control method, related to the field of additive manufacturing, including a powder supply device, a powder upper cylinder, a powder collection cylinder, and multiple 3D printers; the powder upper cylinder is sequentially arranged on the upper part of each 3D printer , the powder collection cylinders are sequentially arranged at the lower part of each 3D printer, and the powder supply device is respectively connected with each of the upper powder collection cylinders and each of the powder collection cylinders. The invention proposes a laser selective melting 3D printing production line system and a control method, which can concentrate powder supply, operate stably, and achieve the effect of saving powder.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a laser selective melting 3D printing production line system and a control method. Background technique [0002] Laser selective melting 3D printing uses laser as the energy source, scans layer by layer on the metal powder bed according to the pre-processed model slice file, and the metal powder melts and solidifies, and then accumulates layer by layer to form the required metal parts. This technology has the advantages of fast forming speed, excellent comprehensive mechanical properties, and can realize the forming of arbitrary complex structures. It has achieved good application results in aerospace, medical, automotive and other fields. [0003] The promotion and application of laser selective melt 3D printing technology inevitably has to deal with the production tasks of small batches of metal parts in the actual production process. A 3D printer with a single feeding cyl...
