Abstract
The invention discloses a three-dimensional printer with a powder laying monitoring device, and belongs to the technical field of additive manufacturing. The three-dimensional printer is characterized in that a camera is arranged above a forming cylinder, and a lens of the camera exactly faces a sintering face or a curing face; the camera is connected with a control system through a wire, the form of each layer of laid powder before sintering or curing is checked through the camera, and pictures or scanning image information of powder laying faces is transmitted to the control system; the transmitted pictures or image information is compared with pictures or image information pre-stored in the system through the control system, and whether powder laying is effective or not is judged; and closed-loop control over the whole powder laying process is achieved, and the yield of printed parts is greatly increased.
Description
Technical field
The present invention relates to and increase material manufacture field, especially " Layered manufacturing, successively superposition " forms the 3D printer of workpiece.
Background technology
3D printing technique is integrated on the basis of Modern CAD/CAM technology, laser technology, Numeric Control Technology, elaborate servo actuation techniques and new material technology growing up.Due to the difference of moulding material used, Forming Theory and the version of 3D printer are also had nothing in common with each other, successively spreading the shaping 3D printer of powder is one of structure of comparatively maturation at present, comprise metal powder, non-metal powder printer, its basic operating procedure has three steps, as shown in Figure 9, the first step: powder feeding; Stand-by powder is delivered to before paving powder scraper by powder feeder unit.Second step: paving powder; Paving powder scraper moves horizontally, and is paved by stand-by powder.3rd step: sintering or solidification; Sintering equipment or solidification equipment work, by practical powder sintering or solidification.These simple three steps are processes of a long-time repeated work, in the repeated work process that this is very long, a step once goes wrong arbitrarily, and the part printed will be scrapped, so people take into full account each step reliability of operation when planing machine; But the paving powder defect that unpredictable element causes, the part rejection problem caused also is quite serious.
Summary of the invention
In order to solve the part rejection problem that paving powder defect causes, the invention provides a kind of 3D printer with paving powder supervising device, this printer is provided with paving powder supervising device, by this device, the paving powder form before every one deck sintering or solidification is checked, and check result or paving powder defect are disposed or reported to the police.
The technical scheme that the present invention takes is: powder feeder unit, piston, moulding cylinder, receipts powder cylinder, paving powder doctor blade device, camera, sintering or solidification equipment and control system etc. constitute and successively spread the shaping 3D printer of powder; The piston of printer is in the chamber of moulding cylinder, and piston can along moulding cylinder precisely movement up and down; Paving powder doctor blade device, above piston, can move back and forth along its guide rail left and right horizontal; The side of powder feeder unit above moulding cylinder, has the function supplying powder on time, according to quantity; Sintering or solidification equipment are placed in the top of piston, in order to complete the practical powder sintering or solidify every one deck and complete; Be characterized in: above moulding cylinder, be provided with camera, its camera lens is directly to sintering or solidification face, and camera is connected with control system by wire, and camera is for taking or scan the paving powder face form after paving powder.
The invention has the beneficial effects as follows, camera checks the paving powder form before every one deck sintering or solidification, and the picture in paving powder face or scan-image information are passed to control system, control system is the picture transmitted or image information and be stored in advance in intrasystem picture or image information is compared, and judge that whether paving powder is effective, if paving powder is effective, control system then instruction sintering or solidification equipment normally works, and completes sintering or solidification; If paving powder lost efficacy, control system then instruction paving powder doctor blade device, powder feeder unit etc. repeats once to spread powder process again, camera checks again to the paving powder form before sintering or solidification, until paving powder is effective or send warning, make whole paving powder process form closed-loop control, printout rate is greatly improved.
