Problems solved by technology

[0002] When the existing 3D printer prints a long suspension structure, due to the constraints of the printer nozzle structure, it is necessary to carry out the support printing in the early stage. The support force points provided by the existing support structure are not uniform, and the support force provided is small. When the length of the suspension structure is too long, the printed body will be greatly bent, and its disadvantages will be further magnified

Abstract

The invention discloses a support-free 3D printing machine. The support-free 3D printing machine comprises a supporting shell, wherein the supporting shell is connected to a power output component of an X-axis translating mechanism; a fusion mechanism which is used for fusing consumable items which enter the supporting shell, a multi-sprayer assembly and a power supply mechanism are further mounted in the supporting shell; the multi-sprayer assembly is used for spraying out the fused consumable items and has a function of switching over multiple sprayers; the power supply mechanism provides power for switching of the sprayers of the multi-sprayer assembly; connecting columns which are uniformly distributed in the peripheral direction at intervals and are connected with the sprayers are arranged on a rotary seat; a plane on which the central axes of the connecting columns are located and a plane on which the central axis of the rotary seat is located are base surfaces; an included angle between each two adjacent base surfaces is the same and is delta; a power output component of the power supply mechanism is connected with the rotary seat; the rotation angle of the driving rotary seat is an integral multiple of delta; and printing on an object in the horizontal direction can be realized, so that support-free printing of a suspension structure is realized.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a support-free 3D printer. Background technique [0002] When the existing 3D printer prints a long suspension structure, due to the constraints of the printer nozzle structure, it is necessary to carry out the support printing in the early stage. The support force points provided by the existing support structure are not uniform, and the support force provided is small. When the length of the suspension structure is too long, the printed body will be greatly bent, and its disadvantages will be further magnified. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a 3D printer that can avoid the need for supports, which can improve the accuracy of the suspension structure while improving the printing efficiency. [0004] In order to realize the above-mentioned technical purpose, the technical scheme adopted in...
