The invention belongs to the technical field of 3D printing, and discloses a multi-purpose 3D space lattice printing system and method based on an industrial robot. In the multi-purpose 3D space lattice printing system based on the industrial robot, a printing body is fixed to a mechanical arm sixth-axis flange plate through a frame structure, and the mechanical arm sixth-axis flange plate is fixed to the end of a mechanical arm; an automatic feeding and extrusion structure is fixed on the mechanical arm and is connected with a heating structure through a polytetrafluoroethylene feeding pipe, and a temperature control structure is mounted on the heating structure; an air pump is arranged behind the mechanical arm and is connected with a heat dissipation structure through an air guide pipe; and an extrusion head structure is located at the lower end of the heat dissipation structure, and the mechanical arm and an integrated control module are independently arranged. It is guaranteed that a tool head can work in various complex poses in the printing process, the integrated control module achieves automatic work through programming, and the heat dissipation system can cool and rapidly solidify a printing model while heat dissipation of a heating core is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a multipurpose 3D space lattice printing system and method based on an industrial robot. Background technique [0002] At present, most of the existing devices for 3D printing thermoplastic materials use a 4-degree-of-freedom frame to heat and press the material at the print head to melt the material and realize stack printing. This kind of printing has two disadvantages. The first is that the diameter of the print head is relatively small, which cannot meet the printing requirements of large-scale and specific printing methods. The other point is that it cannot be printed in complex spaces due to the influence of the printer's degree of freedom and material collapse. [0003] Through the above analysis, the problems and defects of the existing technology are: the diameter of the print head of the existing printing system is relatively small, which cannot meet the...

Problems solved by technology

[0007] (3) When printing in space, the printing temperature, printing speed, extrusion speed, and opening degree of the heat dissipation system have a great influence on whether the printed space object collapses or deforms, and precise control of the above parameters requires repeated experiments. A large amount of accumulated experimental data requires a lot of time, manpower and material resources to complete the experiment and debugging process
