Description
Technical field
The present invention relates to metal 3D printer, more particularly to a kind of one-stop Powder Recovery of metal 3D printing and purified treatment
Device and method.
Background technology
At present, metal 3D printing cost occupies the main reason for high and is that the price of metal dust is higher, manufactures identical chi
Used metal dust cost is higher than traditional diamond-making technique during very little part, while powder using efficiency is low, can not repeat to make
With causing to waste serious.The powder-processed of existing metal 3D printer, which generally comprises, " takes out printout-collection excessive powder-sieve
The several steps of powder-collection ", domestic equipment, external early stage type, low middle end equipment are seldom equipped with the collection for including above-mentioned all steps
Into powder-processed equipment is changed, the recovery of powder, screening needs are manually completed, frequently cut in various intermediate equipments or container
Change so that the process of whole powder-processed is even more more up to 5 hours.In addition, split type powder-processed equipment (such as it is independent
Mixed powder machine, sieving machine, dryer etc.), it is necessary to toggled in equipment room, can not avoid personnel directly with harmful metal powder
Dirt contacts.Reality operating process in, even if wear mouth mask, safety goggles, protective garment, still can not avoid completely airborne dust with
Skin contact.Cause glasses pain, pruitus, long-term hazards are big.Such prolonged processing procedure, seriously occupies equipment
Effective available machine time, reduce production capacity, while operating personnel are absorbed in high pollution, simple and cumbersome work, and it is passive to produce
Working condition.Meanwhile during metal 3D printing, substantial amounts of splash can be produced under laser action.These splash meetings
It is deposited in unsintered powder, hole pattern, which screens out technology, can only remove bulky grain, not worked for extremely tiny splash,
Therefore splash can be brought into next print job circulation, have a strong impact on follow-up print quality.Therefore, existing recovery is set
It is standby that there is following problem：
