Embodiment 1

[0049] Embodiment 1: 3D printer of the present invention for processing any hollow polyhedron workpiece:

[0050] Any hollow polyhedron workpiece (10) such as figure 2 and Figure 5 As shown, after the selected position is placed on the main workbench (12) of the 3D printer of the present invention, there is still an angle γ between the normal vector N of a certain surface and the Z axis, which is less than the critical angle γ c , ( Figure 5 ), so, when using the 3D printer of the present invention to print the workpiece (10) that includes the sheet of this surface, the rotating platform (4) placed on the main body (1) of the 3D printer of the present invention is controlled by a worm gear motor device ( 4,6) drive, rotate an angle or β′( Figure 7 ), the surface is in place to a position perpendicular to the deflection plane of the Z-axis (around the X-axis) of the 3D printer base of the present invention; thereafter, the base platform (2) is driven by a worm gear moto...

Embodiment 2

[0052] Embodiment 2: 3D printer of the present invention for processing multilayer honeycomb structure workpiece:

[0053] The multi-layer honeycomb structure workpiece to be printed can be in any shape, such as the hexagonal honeycomb structure of bees, the square lattice honeycomb structure, and so on. In this embodiment, a workpiece with a multi-layer grid honeycomb structure is selected to describe the 3D printer with a tiltable body of the present invention. When printing a multi-layer honeycomb structure workpiece ( Figure 6 , 610), the 3D printer of the present invention can complete the printing of the entire workpiece in a relatively simple manner. First, in step ①, the main body (1) of the 3D printer of the present invention prints the first layer of honeycomb structure (610a) of the multi-layer honeycomb structure workpiece (610) on the workbench (12, 612) in an upright form without tilting; then The 2nd step, continue in this way, print the selected edge thin la...

Abstract

The invention provides a 3D (three-dimensional) printer with an inclinable machine body. The 3D printer comprises a machine seat part and a 3D printer main body part, wherein the machine seat part is provided with a machine seat platform, a rotary platform, and worm wheel and worm motor devices which are used for respectively driving the machine seat platform to deflect and driving the rotary platform to rotate; the 3D printer main body part comprises a 3D printer main body, a deflectable nozzle, a fixed nozzle, a servo mechanism and an elevated working platform, wherein the 3D printer main body is arranged on the rotary platform of the machine seat, the deflectable nozzle and the fixed nozzle are arranged on a y-axis plate, and the servo mechanism is used for driving the deflectable nozzle. According to the inclination conditions of a cantilever and a cavity curved surface of a machined workpiece, the 3D printer performs no-support printing on the cantilever and the cavity curved surface of the machined workpiece through the rotation of the rotary platform of the machine seat and the deflection of a deflection surface of the machine seat as well as the deflection of the deflectable nozzle on the 3D printer main body part, thus hollow polyhedral, spherical and multilayer honeycomb structure workpieces can be machined, and the compatibility of two categories of 3D printing technologies is realized on the 3D printer. The machined multilayer honeycomb structure workpieces can be importantly applied to the fields of spaceflight, national defense and civil use.

Description

Technical field: [0001] The present invention relates to 3D printing technology. Background technique: [0002] In order to overcome the influence of gravity, the current 3D printers need to use powder materials or photosensitive resin liquid or special materials as supports when printing the cantilever and cavity parts of the workpiece to cope with the influence of gravity. Therefore, some design workpieces with cantilever and cavity structures that do not allow internal support, such as hollow tetrahedron, hexahedron, polyhedron, sphere and multi-layer honeycomb structure workpieces, cannot be printed by current 3D printers. More generally, if the angle γ between the surface normal and the vertical line of the cantilever or cavity included in the design workpiece is less than a certain critical angle γ c ( c Determined by theory and experience), current 3D printers cannot print without using powder materials, photosensitive resin liquid as support or printing support str...
