Raw material powder is layered on workbench, the most under computer, laser beam by scanning device with certain speed and energy density,
Scan by the 2-D data in layering face.The powder of laser scanning just sintering (fusing) becomes certain thickness entity lamella.One layer
Scanned, subsequently next layer being scanned, the most repeatedly, until scanning through structure at all levels, molded article can be obtained.
In SLS and SLM forming process, owing to some metal dust or non-metal powder easily aoxidize, need shaping
During be constantly passed through protective gas, it is to avoid drip molding aoxidizes.When SLS and SLM shapes at present, protective gas air intake installation
Still suffering from problems with: 1. inlet channel is single, forming cavity charging efficiency is low.Protective gas air intake installation often uses one to enter
Gas passage, therefore in forming cavity gas replenishment process, inefficient.2. air-flow is uneven.Often there is corner in admission line, when
When gas is by this corner, easily forms air-flow dead band, thus cause air-flow uneven.3. gas flow and flowing side it are difficult to control to
To.In forming process, when protecting gas skewness in forming cavity, air intake installation cannot adjust gas flow and flowing automatically
Direction, therefore produces certain impact to drip molding quality.
