As shown in connection with fig. 2, a kind of 3D printer powder supply mechanism, including the first powder feeding cylinder 100, first successively arranged side by side Powder Recovery cylinder 200, formation cylinder 300, the second Powder Recovery cylinder 400, the second powder feeding cylinder 500, further include a scraper, scraper is successively It is done along the first powder feeding cylinder 100, the first Powder Recovery cylinder 200, formation cylinder 300, the second Powder Recovery cylinder 400, the second powder feeding cylinder 500 It moves back and forth, the first powder feeding cylinder 100, the first Powder Recovery cylinder 200, formation cylinder 300, the second Powder Recovery cylinder 400, the second powder feeding 500 insole portion of cylinder is not provided with push plate 600.First powder feeding cylinder 100, the first Powder Recovery cylinder 200, formation cylinder 300, the second powder Last recovery tank 400,500 inner pushing plate 600 of the second powder feeding cylinder are driven by independent driving mechanism respectively.First powder feeding cylinder 100, second are sent Feed powder 700 is installed in powder cylinder 500 respectively.Feed powder is separately recovered in first Powder Recovery cylinder 200, the second Powder Recovery cylinder 400 700。
The 3D printer powder supply mechanism Method of printing includes the following steps:
The first powder feeding cylinder of S1 100, which rises, prepares powder feeding, and the first Powder Recovery cylinder 200 decline certain distance prevents the material of recycling Powder 700 is blown off;
Feed powder 700 in first powder feeding cylinder 100 is sent into formation cylinder 300 and completes powdering printing by S2 scraper, and will be extra Feed powder 700 is sent into the recycling of the second Powder Recovery cylinder 400, and scraper marches to the other side;
The second powder feeding cylinder of S3 500, which rises, prepares powder feeding, and the second Powder Recovery cylinder 400 decline certain distance prevents the material of recycling Powder 700 is blown off;
Feed powder 700 in second powder feeding cylinder 500 is sent into formation cylinder 300 and completes powdering printing by S4 scraper, and will be extra Feed powder 700 is sent into the recycling of the first Powder Recovery cylinder 200, and scraper is returned to initial position, repeats aforesaid operations.
Specific implementation step is as follows: fixing tentatively blade construction initial position on the upper left side of powdering structure, from left to right defines To promote stroke, it is defined as return stroke from right to left.In the propulsion stroke of scraper, the sequence of motion of powdering structure are as follows: the One powder feeding cylinder rises certain distance, prepares powder feeding;First Powder Recovery cylinder declines certain distance, and useless powder is avoided to be blown off;Forming Cylinder is completed in powdering, after the completion of printing, declines certain distance, preparation prints next time;Second Powder Recovery cylinder decline one Set a distance recycles unspent useless powder;Scraper reaches the upper right side of powdering structure, and stroke is promoted to terminate.
In the return stroke of scraper: the second powder feeding cylinder rises certain distance, prepares powder feeding.The decline of second Powder Recovery cylinder Certain distance prevents useless powder from being blown off, and formation cylinder is completed in powdering, after the completion of printing, declines certain distance, prepares next Secondary printing.First Powder Recovery cylinder declines certain distance, recycles useless powder, and blade construction runs to upper left side initial position.Again Aforesaid operations.
Powdering can be carried out in promoting stroke and return stroke and 3D printing operates.Ideally, maximum can be improved Efficiency 50% can reduce the higher printing cost of current 3D printing technique and longer production time to a certain extent.
