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

Abstract

The present invention discloses a five-freedom-degree rapid forming processing apparatus, which comprises a frame (1), material disks (3) on the top portion of the frame (1), an operating plate (6), a screen (7), and a control plate (8), and further comprises a two-freedom-degree spraying head assembly (2) capable of freely moving along X axis and Z axis, a clamping device (4), and a three-freedom-degree platform assembly (5) capable of freely rotating along Y axis, Z axis and A axis, wherein the operating plate (6) and the screen (7) are arranged on the bottom portion in front of the frame (1). With the five-freedom-degree rapid forming processing apparatus of the present invention, the step effect can be eliminated, the surface quality of the printed inclined plane can be increased, the processing efficiency on the circular cross-section parts is high, the processing on the spherical platform can be achieved, and the space utilization rate is good.

Description

technical field [0001] The invention relates to a rapid prototyping device, in particular to a five-degree-of-freedom rapid prototyping processing device, 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 ...
