Technical Field
The invention relates to the technical field of sand mold 3D printing, in particular to 3D printer equipment and a printing method thereof.
Background
Sand mould 3D prints and has played important effect in the quick research and development of foundry goods of realization in the casting field, in the research and development process of general quick appearance spare, 3D prints the time that the part was spent and has occupied very big part, current 3D printing scheme is spread the powder earlier, then beat printer head inkjet and print, though the motion is simple, the collision of scraper blade with beating printer head has been avoided, but printing efficiency is too low like this, the production requirement that the machine printed can not be satisfied, and still, it is long to print time, fault such as shut down appears, lead to printing the part unsuccessful, based on above defect and not enough, it is necessary to improve current technique, design a 3D printer equipment and printing method.
Disclosure of Invention
The invention mainly solves the technical problem of providing 3D printer equipment and a printing method thereof, so that a printing head can jet ink simultaneously when a scraper plates are used for paving sand, thereby reducing the printing time, improving the printing efficiency, improving the printing speed of a sand mold 3D printer and greatly reducing the shutdown risk caused by environmental reasons; valuable time is gained for developing some sample pieces quickly.
In order to solve the technical problems, the invention adopts a technical scheme that: the 3D printer equipment comprises a support, a forming box, a 3D printer, a scraper assembly and a storage bin, wherein the forming box is installed on the support, the 3D printer and the scraper assembly which are located above the forming box are installed at the upper end of the support, the storage bin is arranged at the side end of the support, and the storage bin is in butt joint with the scraper assembly.
Preferably, the scraper blade subassembly includes single-axis drive, by single-axis drive horizontal migration's scraper blade, and the outside extension in scraper blade bottom is provided with flourishing material portion, and flourishing material portion up end is provided with the blanking inclined plane, and the scraper blade side is provided with the baffle that is located flourishing material portion top, forms the blowing space between scraper blade and the baffle, and the opening between flourishing material portion and the baffle is the blanking mouth.
