Description
Technical field
The invention belongs to rapid shaping 3D printing technique fields, specially a kind of old Powder Recovery of laser formation is recycled
System and method.
Background technology
3D printer can realize that present industrialization aspect is most popular to be belonging to laser by a variety of technologies
Sintered powder technique SLS.SLS methods make the energy using infrared laser, the Modeling Material for using mostly dusty material.During processing,
Powder is preheating to the temperature of slightly less than its fusing point first, then powder is paved in the presence of Gua Fen mechanisms；Laser beam exists
Selectively sintered according to layering cross section information under computer controls, carried out next layer of sintering after the completion of one layer again, all
Remove unnecessary powder after having sintered, then can be obtained by a part for sintering.
Remaining old powder carries out the method for recycling and is typically to be filtered out with sieving machine after existing laser formation
Qualified old powder is put into mixed powder container, then is used in mixed powder equipment toward a certain proportion of new powder of mixed powder container addition and pouring into
Stirrer paddle stirring mixing, in mixed powder finally poured into molding main-machine plus powder cabin, the method has several drawbacks in that：
Firstth, the powder price is expensive and toxic, in the qualified old powder that will be screened is equipped with mixed powder container, stirs
Poured into during mixing mixed-powder, by mixed powder molding main-machine plus medium three processes of powder cabin can cause dust to fly
Raise, cause to waste and be harmful to health；
Secondth, stirring mixed-powder during new and old powder can not cmpletely mix, especially the dead angle of container more without
Method is well mixed, and the part strength after shaping can be made to be deteriorated very coarse with surface；
3rd, existing mixed powder equipment and sieving machine equipment and powder feeding machine equipment cannot be supported the use, and increased operation step
Suddenly, operation inconvenience is caused, the more time is expended and a large amount of dust can be produced, reduce production efficiency.
The present invention is namely based on what such case was made
The content of the invention
The present invention seeks to overcome the deficiencies in the prior art, there is provided a kind of old Powder Recovery of the laser formation of simple structure is again
