Four-axis three-dimensional printer

Abstract

The invention discloses a four-axis three-dimensional printer. The four-axis three-dimensional printer comprises a frame assembly (1), a material plate (5) arranged on the top of the frame assembly (1), a platform rotating assembly (2) capable of rotating round the Z axis, a crank-connecting rod print head assembly (3) capable of moving flexibly and freely and a print head moving assembly (4) driving the print head assembly (3) to move along the Z axis, wherein the platform rotating assembly (2), the crank-connecting rod print head assembly (3) and the print head moving assembly (4) move cooperatively to realize high-efficiency and high-accuracy three-dimensional printing. According to the four-axis three-dimensional printer, the step effect can be removed, the surface quality of printing slopes can be improved, the processing efficiency of circular-section parts is high, and control is simple.

Description

technical field [0001] The invention relates to a three-dimensional printer, in particular to a four-axis three-dimensional printer, belonging to the technical field of rapid prototyping. Background technique [0002] Fused deposition has the advantages of low maintenance cost, safety and reliability, and no waste. It is widely used in product development, rapid mold making, design and development of medical devices, and prototype production of human organs. It represents an important development direction of rapid prototyping manufacturing technology. [0003] The platform of the existing 3D rapid prototyping machine on the market usually has only three degrees of freedom, and the required parts are fused and deposited by moving the platform in three directions relative to the X, Y, and Z axes of the print head. This kind of rapid prototyping machine has two obvious disadvantages: on the one hand, the platform can only move relative to the nozzle, and the processing efficie...

AI Technical Summary

Problems solved by technology

This kind of rapid prototyping machine has two obvious disadvantages: on the one hand, the platform can only move relative to the nozzle, and the processing efficiency is low; There will be a "step effect", which will seriously affect the surface accuracy of the product

Using adaptive layering can weaken the "step effect", but increase the number of layers and increase the molding time; and the "step effect" cannot be completely eliminated. For parts with high surface accuracy requirements, after the parts are printed, Post-processing is also required, which undoubtedly increases the cost and time of processing
