Description
Technical Field
The invention relates to metal 3D printing equipment, in particular to electron beam additive printing equipment.
Background
Additive manufacturing is commonly known as 3D printing, and is a manufacturing technology which integrates computer aided design, material processing and forming technology, is based on a digital model file, and is used for stacking special metal materials, non-metal materials and medical biological materials layer by layer through software and a numerical control system according to modes of extrusion, sintering, melting, photocuring, spraying and the like to manufacture solid objects.
The main metal 3D printing process which can be used for directly manufacturing metal functional parts at present comprises the following steps: including Selective Laser Sintering (SLS) techniques, Direct Metal Laser Sintering (DMLS), Selective Laser Melting (SLM) techniques, Laser Engineered Net Shaping (LENS) techniques, and Electron Beam Selective Melting (EBSM) techniques, among others.
Selective Laser Sintering (SLS) and selective laser sintering, as the name suggests, the adopted metallurgical mechanism is a liquid phase sintering mechanism, the powder material is partially melted in the forming process, the powder particles retain the solid phase core thereof, and the powder densification is realized through subsequent solid phase particle rearrangement and liquid phase solidification bonding. Because the strength of the sintered part is low, the high strength can be achieved only by post-treatment, and the manufactured three-dimensional part generally has the problems of low strength, low precision, poor surface quality and the like.
Selective laser melting, SLM technology was developed based on SLS, both of which have similar basic principles. The SLM technology needs to completely melt metal powder to directly form a metal part, so before a laser beam of a high-power-density laser starts scanning, a horizontal powder spreading roller firstly spreads the metal powder on a substrate of a processing chamber, then the laser beam selectively melts the powder on the substrate according to the contour information of the current layer to process the contour of the current layer, a lifting system descends a distance of the thickness of the layer, a powder spreading roller is rolled to spread the metal powder on the processed current layer, equipment is adjusted to the next layer for processing, and the layer-by-layer processing is carried out until the whole part is processed. The whole processing process is carried out in a processing chamber which is vacuumized or is protected by gas, so as to prevent the metal from reacting with other gases at high temperature. The selective laser melting forming technology can obtain a formed part with metallurgical bonding, compact structure, high dimensional accuracy and good mechanical property, but has the advantages of small forming range, very low forming efficiency and high cost.
Laser Metal Deposition (LMD) was first proposed by the american Sandia national laboratory in the last 90 s and was subsequently developed in many parts of the world in succession, and since many universities and institutions were independently studied, the name of this technology is many, although the names are different, their principle is basically the same, and during the forming process, powder is collected on a working plane through a nozzle, and Laser beams are collected at the same time, the powder action points are overlapped, and a stacked and clad entity is obtained by moving a table or the nozzle. The LENS technology uses a kilowatt-level laser, and the adopted laser has a large focusing spot which is generally more than 1mm, so that a metallurgically bonded compact metal entity can be obtained, but the dimensional precision and the surface smoothness are not good enough, and the laser can be used after further machining.
In the research field, a composite additive manufacturing technology adopting a laser technology also appears, the composite additive manufacturing is performed by adopting laser as an energy source and combining wire feeding and powder feeding technologies, but the structure for realizing wire feeding and powder feeding is complex and the efficiency of the laser is low, so that the composite additive manufacturing technology is difficult to realize in actual production due to the fact that the laser needs to be focused.
