Additional material manufacturing equipment with high-response parallel leveling mechanism and leveling method

Abstract

The invention discloses additional material manufacturing equipment with a high-response parallel leveling mechanism and a leveling method. The bottom of a rack is provided with a Y-direction moving mechanism, a supporting platform is arranged on the Y-direction moving mechanism, Z-direction moving mechanisms are arranged on the two sides of the rack correspondingly and connected with an X-direction moving mechanism, and the X-direction moving mechanism is provided with a printing sprayer and a distance measuring device. The Z-direction moving mechanisms are used for driving the X-direction moving mechanism to vertically ascend and descend up and down and move in the Z direction, the X-direction moving mechanism drives a vertical support and the printing sprayer and the distance measuringdevice on the X-direction moving mechanism to horizontally move in the X direction. A printing platform is installed on the supporting platform in a posture adjusting and supporting manner through a telescopic device and a virtual fixing rod. By means of the additional material manufacturing equipment, the additional material manufacturing leveling precision and response can be effectively improved, and accordingly the additional material manufacturing final effect is improved.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to an additive manufacturing equipment with a printing platform leveling device and a distance measuring device, and a leveling method suitable for the additive manufacturing equipment. Background technique [0002] Additive manufacturing equipment, usually referred to as three-dimensional printing (3D printing, 3DP) equipment, is a kind of equipment that uses additive manufacturing to superimpose layers of materials and print out three-dimensional objects. In the process of additive manufacturing, whether the printing platform is level is closely related to the effect and quality of additive manufacturing. The incomplete level of the printing platform is one of the main reasons for the geometric shape error of the printed parts. When setting printing parameters, the thickness of the printing layer can be set below 0.5mm. If the printing platform is not completely horizont...

AI Technical Summary

Problems solved by technology

When setting printing parameters, the thickness of the printing layer can be set below 0.5mm. If the printing platform is not completely horizontal and the longitudinal distance between the highest point and the lowest point is greater than this value, it may cause the printed product to be very solid at the highest point. The lowest point cannot be fused with the printing platform; due to the difference in the melting strength of the first printed layer and the...
