Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0036] Such as figure 2 As shown, the 3D printer provided by the present invention includes a plurality of nozzles and a height adjustment device, and the height adjustment device is respectively connected to the plurality of nozzles for adjusting the plurality of nozzles to be located at different heights.

[0037] In this embodiment, the number of spray heads is two, that is, the first spray head 10 and the second spray head 20 , but the present invention is not limited thereto. The height adjustment device...

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.

Description

technical field [0001] The invention relates to a printing device, in particular to a 3D printer and a 3D printing method. Background technique [0002] With the development of 3D printing equipment and the pursuit of fast printing needs, 3D printers with dual nozzles and more than three nozzles are increasingly favored by the market. In the multi-head 3D printers currently seen, the printing heads are basically on the same reference plane. Such as figure 1 The 3D printer shown contains the A nozzle and the B nozzle in the same reference plane. [0003] Existing multi-nozzle 3D printers only have one nozzle working during actual printing, while the other nozzle is idle and moves horizontally along with the direction of the printing nozzle. In this way, when one nozzle prints, the other nozzle may scratch the printed object (the higher the printing accuracy, the higher the probability of occurrence), resulting in rough and uneven surface of the printed object (material acc...
