Spray head automatic distance adjustment 3D (Three Dimensional) printer

Abstract

The invention provides a spray head automatic distance adjustment 3D (Three Dimensional) printer. The printer comprises a spray head, a spray head moving bracket and a hot bed, wherein the spray head is arranged on the spray head moving bracket and can move in the vertical and horizontal directions under driving of the spray head moving bracket; a distance measuring sensor is arranged beside the spray head; the distance between the spray head and the hot bed is measured by the distance measuring sensor; when the distance reaches a preset distance, the spray head moving bracket is controlled to stop the movement of the spray head in the vertical direction. The 3D printer can realize automatic distance measurement and adjust to required printing distance and realizes accurate, quick and high-precision spray head distance adjustment and control, so that the quality and the effect of a 3D printing product is improved.

Description

technical field [0001] The present invention relates to the technical field of 3D printers, in particular to a 3D printer with automatic nozzle distance adjustment. Background technique [0002] 3D printing has become a trend and has been widely used in the field of design, especially in industrial design, digital product mold opening, automobile, aerospace, etc. It can complete the printing of a mold within a few hours, saving a lot of time for products to go to the market Development time. The distance control between the nozzle and the hot bed of the existing 3D printer is realized by a trigger switch. The trigger switches are respectively installed at the end positions of the x, y, and z axes of the printer. When printing starts, the print head moves to the origin position. When the print head moves downward and touches the trigger switch of the y axis, the print head stops moving. This position is the position of the print head. The initial position, and the distance...

AI Technical Summary

Problems solved by technology

However, in the prior art, the method of adjusting the distance through the trigger switch is very inaccurate and the adjustment operation is very cumbersome and time-consuming. If the printer is manually assembled, it can only be slowly adjusted to find the best nozzle and hot bed to finally fix the trigger switch. position, which will result in a loss of accuracy, as well as a waste of time and effort
