Abstract
The invention discloses a 3D printer which comprises a plurality of nozzles and a height adjusting device connected with the nozzles, wherein the height adjusting device is used for adjusting the nozzles so as to position the nozzles at different heights. When one nozzle works, other nozzles can be in a state of being higher than the working nozzle. The invention further discloses a 3D printing method. When the working nozzle of the 3D printer moves leftwards and rightwards, the other nozzles are far away from a printing plane, so that the situation that the non-working nozzles scrap the printing plane and the printing effect is affected is avoided.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
As shown in Figure 2,3D printer provided by the invention comprises multiple shower nozzle and arrangement for adjusting height, and described arrangement for adjusting height connects described multiple shower nozzle respectively, for regulating described multiple shower nozzle to be located at different height.
In the present embodiment, the quantity of shower nozzle is two, i.e. the first shower nozzle 10 and the second shower nozzle 20, but the present invention is not as limit.Arrangement for adjusting height comprises the cross bar 30 of level connection joint two shower nozzles, and to be fixed on a base plate 90 and the support member 40 be supported in the middle part of described cross bar 30, all has the elastic component 50 connecting described base plate 90 and cross bar 30 in the both sides of described support member 40.
Cross bar 30 is movably connected the first shower nozzle 10 and the second shower nozzle 20, and namely the first shower nozzle 10 and the second shower nozzle 20 can rotate relative to cross bar.When 3D printer does not work, first shower nozzle 10 and the second shower nozzle 20 naturally droop and all the time perpendicular to printing plane 100, in preferred version, first shower nozzle 10 is identical apart from the height printing plane 100 with the second shower nozzle 20, and the first shower nozzle 10 is identical with the specification of the second shower nozzle 20, the distance of distance support member 40 is identical, and in other words, support member 40 is fixed on the middle part of cross bar 30 movably.But the present invention is not as limit, as long as meet 3D printer when not working, the first shower nozzle 10 and the second shower nozzle 20 do not contact and print plane.
All there is in the both sides of described support member 40 elastic component 50 connecting described base plate 90 and cross bar, under the support of elastic component 50, do not contact printing plane with the second shower nozzle 20 to make the first shower nozzle 10.In preferred version, the elastic component 50 of both sides is identical to the distance of described support member 40, and the spring that the elastic component 50 of both sides adopts coefficient of elasticity identical, when 3D printer does not work, the elastic component 50 of both sides all props up cross bar 30, make cross bar 30 maintenance level, now, the first shower nozzle 10 is identical apart from the height printing plane 100 with the second shower nozzle 20.
Arrangement for adjusting height also comprises motor 70 and connecting rod 80, and motor 70 is positioned at the top of described cross bar 30, and described connecting rod 80 is flexibly connected described motor 70 and described cross bar 30 respectively.Concrete, connecting rod 80 is riveted on the side of cross bar 30 and can rotates by opposing rail 30, and when 3D printer does not work, connecting rod 80 is perpendicular to cross bar 30.
Motor 70, for providing power, makes connecting rod 80 to move up and down, and to impel cross bar 30 to prize relative to support member about 40, changes the height of multiple shower nozzle whereby.In preferred version, motor 70 comprises gear 60, and gear 60 is arranged at the inside of motor 70, and connecting rod 80 is a tooth bar, and motor 60 is with carry-over bar to realize moving up and down by driving the rotation of its internal gear 60.
Describe a kind of 3D Method of printing realized by 3D printer of the present invention below in detail.
Generally speaking, 3D printer of the present invention controls described multiple shower nozzle by the arrangement for adjusting height connecting multiple shower nozzle respectively, make described multiple shower nozzle be positioned at different height, and the shower nozzle of work at present is positioned at minimum position all the time, prints plane 100 realization printing to contact.
Concrete, when 3D printer does not work, the first shower nozzle 10 is identical apart from the height printing plane 100 with the second shower nozzle 20, and when 3D printer works, needs to select some shower nozzles to print, and this sentences the first shower nozzle 10 and works as example is described.When needs first shower nozzle 10 works, gear 60 in motor 70 rotates counterclockwise (direction of arrow in figure), connecting rod 80 is driven to move downward, thus the side making cross bar 30 connect described connecting rod 80 moves downward and drives the first shower nozzle 10 to move downward, until contact prints plane 100.Now, motor 70 locks current location, and the first shower nozzle 10 is started working.Be understandable that, the first shower nozzle 10 need of work moves around in the horizontal direction, and therefore 3D printer of the present invention also comprises the motor that can realize moving horizontally, but is the known techniques in 3D printer field due to this, repeats no more herein.
When needs second shower nozzle 20 works, gear 60 in motor 70 rotates clockwise, connecting rod 80 is driven to move upward, thus the side making cross bar 30 connect described connecting rod moves upward and drives the second shower nozzle 20 to move downwardly to a rational position, this rational position is slightly larger than the diameter width of institute's materials material.Now, motor 70 locks current location, and the second shower nozzle 20 is started working.
In like manner, when 3D printer end-of-job, by the rotation of motor 70 middle gear 60, make cross bar 30 recover level, the first shower nozzle 10 and the second shower nozzle 20 are got back to sustained height and lock current location.
By 3D printer provided by the invention, when a certain shower nozzle work, all the other shower nozzles can keep the state higher than the nozzle position of work, thus when the nozzle right of work is moved, remaining shower nozzle is away from printing plane, avoid idle shower nozzle to scrape printing plane, affect printing effect.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these changes and distortion.
