Description
Technical Field
The invention belongs to the technical field of 3D printing, and particularly relates to a Cartesian coordinate system-based Fourier transform 3D printing system.
Background
The traditional 3D printer based on the cartesian coordinate system at present realizes the processing of the whole workpiece layer by layer in a manner of moving along 3 orthogonal axes in space. Therefore, no matter whether the machined surface has a high-dimensional curved surface or not, the traditional 3D printer adopts a linear interpolation form to print in the whole machining process, and the printing mode has the following disadvantages: 1) the problem of printing direction change when the cambered surface or curved surface material is formed is not considered, the distance between the lines formed by the ejected material in the layer-by-layer printing can be changed, and the mechanical property of a printed piece is poor; 2) when the material is printed layer by layer to form an arc surface or a curved surface, the geometric information of the high-dimensional curved surface cannot be accurately captured by adopting a linear interpolation mode, so that the surface roughness of the printed piece cannot meet the technical requirement, and the precision of the printed piece is directly reduced. 3) Particularly, when a high-dimensional curved surface with obvious curvature change is printed, the traditional 3D printer still adopts a straight line difference compensation mode to approach the curved surface, and the printing efficiency is reduced by adopting a small step length mode when the high-precision curved surface is obtained by adopting the printing mode; on the contrary, the printing precision can not be guaranteed, and the advantage of 3D printing rapid prototyping is seriously influenced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a cartesian coordinate system-based fourier transform 3D printing system, which makes up the defects of the current 3D printing system in printing high-dimensional curved surfaces, and the main research content is as follows: based on the relation between the frequency and the waveform response in the Fourier function, the arbitrarily selected high-dimensional curved surface is equivalent to a series of continuously measured signals, and the geometric information of the high-dimensional curved surface is captured by superposing a limited number of sine wave signals with different frequencies, different amplitudes and different phases; when the curvature of the curve is not changed, the curve with single curvature can be obtained only by the fixed rod length, and when the curvature of the curve is changed, the geometric information of the high-dimensional curved surface can be described by the motion of different rod lengths and different frequencies; wherein the rod length in the system represents the amplitude of the high-dimensional curved surface, and different frequencies represent the speed of curvature change; therefore, the connecting rods with different lengths can be used for realizing the movement of the spray head in the radial direction, meanwhile, the circumferential movement of the spray head is realized by the circumferential swing of the connecting rods, the longitudinal displacement of the spray head is finally realized by the ball screw layer-by-layer printing, and the advantage that the Fourier transform can acquire high-frequency information is used for the novel 3D printing system capable of realizing high-dimensional curved surface printing.
In order to achieve the purpose, the invention adopts the technical scheme that: the Fourier transform 3D printing system based on the Cartesian coordinate system comprises a base (1) and is characterized in that two upright posts (7) are fixed on the base (1); each upright post (7) is fixed with a longitudinal driving motor (13) through a Z-axis frame (12); a longitudinal driving motor (13) is connected with an X-axis rack A (10) through a lead screw nut (11), the X-axis rack A is connected with a longitudinal guide rod, and the moving direction of the X-axis rack A is determined through the longitudinal guide rod; the lower sides of the X-axis machine frame A and the X-axis machine frame B are respectively connected with a transverse guide rod frame A and a transverse guide rod frame B, and a transverse driving motor is fixed on the transverse guide rod frame A; the transverse driving motor is connected with a rotary motor frame A through a transverse lead screw nut, the rotary motor frame A is connected with a transverse guide rod, and the moving direction of the rotary motor frame A is determined through the transverse guide rod; the lower side of the rotating motor frame A is connected with a rotating motor frame B, and the lower side of the rotating motor frame B is sequentially connected with a primary connecting rod assembly, a secondary connecting rod assembly and a tertiary connecting rod assembly; the primary connecting rod assembly, the secondary connecting rod assembly and the tertiary connecting rod assembly can respectively rotate under the driving of a primary motor, a secondary motor and a tertiary motor; the base is also provided with a Y-axis frame, and the Y-axis frame is connected with a Y-axis driving motor; a Y-axis guide rod frame A on the base is connected with a Y-axis guide rod; the Y-axis driving motor is connected with the printing platform through a Y-axis lead screw nut and a printing platform frame, the printing platform is connected with a Y-axis guide rod frame B, and the moving direction of the printing platform is determined through a Y-axis guide rod;
