Problems solved by technology

[0004] The nozzles used in 3D printers mainly include piezoelectric type, thermal foam type, melt extrusion type, and micro-injector type. Among them, piezoelectric type and thermal foam type nozzles are suitable for jetting "ink" with low viscosity, and melt extrusion type Pressure nozzles are suitable for spraying thermoplastics, so the material scope of these types of nozzles is relatively limited
However, the current micro-injector type 3D printer usually only has one nozzle, and the volume of the barrel is limited, so it cannot be continuously fed, so it can only be used for the forming experiment research of small workpieces of a single material, and it is difficult to be used for multiple materials and larger workpieces.

Abstract

The invention discloses a micro injector type multi-spray-head three-dimensional printing machine which can simultaneously use various kinds of fluid materials to print work pieces. The micro injector type multi-spray-head three-dimensional printing machine is provided with an automatic feed system, can continuously work for a long time and can manufacture large work pieces formed by various materials. The technical scheme is that the three-dimensional printing machine comprises a plurality of injector type spray heads for injection, a plurality of injectors for storage, the feed system, a control system, a machine body, a work bench, a horizontal left-right moving mechanism, a movable beam and a computer controlling and driving system.

Description

technical field [0001] The invention relates to a three-dimensional printer, in particular to a three-dimensional printer using a plurality of micro-injectors as nozzles. Background technique [0002] A 3D printer is also called a 3D rapid prototyping machine. According to the workpiece graphics control instructions issued by the computer, the nozzles of this printer can selectively eject and deposit the "ink" in it on the workbench substrate below, and the "ink" solidifies quickly. Finally, the first layer of two-dimensional graphics section of the workpiece is formed. After the formation of this layer is completed, the nozzle is raised to a small layer height, and the second layer of two-dimensional graphics section is formed according to the similar process of the first layer. This layer is superimposed on the upper layer and bonded to each other as a whole. The two-dimensional forming is repeated layer by layer until the entire three-dimensional workpiece is formed. Th...
