The whole process unit of selecting property lf is made up of powder cylinder and moulding cylinder.During work, on powder cylinder piston (powder feeding piston)
Rise, by scraper by powder uniform spreading on the molding base station being arranged on moulding cylinder piston (working piston), computer is according to former
The hierarchical model of type controls the two-dimensional scan track of laser beam, and sintering solid dusty material is with one of formation part selectively
Aspect.After powder completes one layer, moulding cylinder piston declines a thickness, and paving powder system spreads new powder again at molding base station.Control
Controlling laser beam scans the new layer of sintering again.So move in circles, be layering, until 3 d part molding.Finally, by unsintered
Powder Recovery is in powder cylinder, and takes out profiled member.
The optics that the core component of selective laser fusion apparatus is made up of laser generator, beam expanding lens, galvanometer, field lens
System；Further, due to the characteristic of metal dust, whole print procedure is the most airtight at a full nitrogen or argon
In forming bin, optical system laser needs out incide molding base by being arranged on the window mirror (quartz glass) of forming bin
Platform.In melted (SLM) the equipment print procedure of selective laser, forming bin has metallic dust and the drift of oxidization of metal powder thing
Floating, if floating thing is attached on window mirror to cause the laser beam quality inciding in forming bin to decline, affect metal zero
The printing shaping quality of part, can cause time serious cannot molding.
