Problems solved by technology

Combining thermosetting fluid materials and 3D printing technology can realize the rapid prototyping of such products. The existing thermosetting 3D printing technology is extrusion molding, which is to extrude colloidal thermosetting fluid materials into filaments, and use filaments to outline Outline the desired outline, and then solidify, and stack layers according to this method to form a three-dimensional structure, but it is difficult to print a fine model with this printing method

Embodiment 1

[0027] A thermal curing printing method in this embodiment includes:

[0028] S11. The driving mechanism drives the printing platform to move down from the liquid level of the liquid tank to stop at the corresponding layer height in the liquid tank storing the heat-curing fluid material;

[0029] S12. The scraper assembly scrapes the liquid level of the liquid tank after the printing platform moves in the liquid tank;

[0030] S13. The thermal curing unit solidifies the leveled liquid surface of the liquid tank to form a model structure with a corresponding layer height;

[0031] S14. Determine whether the printing is complete, if yes, end; if not, repeat S11-S14.

[0032] The heat-curing fluid material can be heat-curing silicone rubber, heat-curing resin, heat-curing glue, heat-curing liquid silicone, etc. In other words, the corresponding type of heat-curing fluid material can be selected as the printing material according to the performance requirements of the printed mod...

Embodiment 2

[0046] combine figure 2 with 3 , this embodiment proposes a thermosetting printing device, which is used to implement a thermosetting printing method described in any one of the technical solutions in Embodiment 1, including: a printing platform 005, a liquid tank 010, a refrigerator 014, and a scraper assembly , the thermal curing unit 006 and the driving mechanism, wherein the driving mechanism is used to drive the printing platform 005 to move; the refrigerator 014 is located outside the liquid tank 010, and the liquid tank 010 is used to hold liquid silicone; the scraper assembly is used to scrape the printing platform 005 the liquid surface after moving in the liquid tank; the thermal curing unit 006 is used to solidify the liquid surface of the liquid tank after scraping to form a model 021 structure with a corresponding layer height.

[0047] If it is printing with support, it also includes an extruding print head 019 located above the liquid tank 010, and the extrude...

Abstract

The invention discloses a thermocuring printing method and device, and belongs to the technical field of 3D printing. The method comprises the steps that a driving mechanism drives a printing platform to move downwards by a corresponding layer height from the liquid level of a liquid tank in the liquid tank where a thermocuring fluid material is stored to stop; a scraper assembly scrapes the liquid level of the liquid tank after the printing platform moves in the liquid tank; a thermocuring unit cures the leveled liquid level of the liquid tank to form a model structure with the corresponding layer height; whether printing is finished or not is judged, and if yes, ending is carried out; and if not, the steps are repeated. The device part comprises the printing platform, the liquid tank, a refrigerator, the scraper assembly, the thermocuring unit and a driving unit. The device has the advantages of high printing fineness and high printing quality.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a thermosetting printing method and a printing device thereof. Background technique [0002] Thermosetting fluid refers to a single-component or multi-component mixture that does not form at room temperature or has a slow molding speed, and needs to be heated and catalyzed to accelerate solidification. Common thermosetting fluids include thermosetting silicone rubber, thermosetting resin, thermosetting glue, thermal Cured liquid silica gel, etc. This material is widely used in molding molds, injection molding processes and other products due to its excellent physical and chemical properties. Combining thermosetting fluid materials and 3D printing technology can realize the rapid prototyping of such products. The existing thermosetting 3D printing technology is extrusion molding, which is to extrude colloidal thermosetting fluid materials into filaments, and use fi...
