Example Embodiment

[0016] The present invention will be further illustrated by specific embodiments below:

[0017] Such as figure 1 with figure 2 As shown, the selective laser melting SLM forming table 6 is included. The selective laser melting SLM forming table 6 is divided into four uniform forming areas. The four forming areas are respectively a first forming area I, a second forming area II, In the third forming area III and the fourth forming area IV, each of the forming areas has its own independent galvanometer system, and the galvanometer components in each galvanometer system are controlled by the corresponding galvanometer motion controller 5 respectively. All the galvo motion controllers 5 are connected to the central controller 7 for control. The galvanometer system includes an X-axis galvanometer 1 and a Y-axis galvanometer 2 which are arranged according to the incident direction of the respective laser beams 4. The X-axis galvanometer 1 and the Y-axis galvanometer 2 constitute the ...

Abstract

The invention relates to large-format selective laser melting (SLM) equipment of a multi- galvanometer, which comprises an SLM forming table, wherein the SLM forming table is divided into four uniform forming areas, respective separate galvanometer systems are respectively arranged above the forming areas, galvanometer components in all of the galvanometer systems are respectively in control connection with respective corresponding galvanometer motion controllers, all of the galvanometer motion controllers are in control connection with a central controller, so as to form parts which cannot be manufactured by the traditional SLM equipment, and additionally, the processing efficiency of the parts is increased.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to a multi-mirror large-scale selective laser melting SLM equipment. Background technique [0002] Selective laser melting SLM is a method of direct forming of metal parts and is the latest development of rapid prototyping technology. This technology is based on the most basic idea of ​​rapid prototyping, that is, the "incremental" manufacturing method of layer-by-layer cladding, and directly forms parts with specific geometric shapes according to the three-dimensional CAD model. During the forming process, the metal powder is completely melted to produce metallurgical bonding. Metal parts with complex shapes and structures that cannot be manufactured by traditional machining methods are one of the main directions for the application of laser rapid prototyping technology. Has the following advantages: [0003] (1) It can be directly made into terminal metal products with...
