Embodiment 1

[0119] 1. Printer system construction

[0120] The 3D printer system designed by the present invention consists of three main parts: a mechanical printing body with a rectangular box structure, a data acquisition board, and a host computer (software). The mechanical body of the box-type mechanism includes aluminum alloy profiles, stepping motors, extruders, heating panels, functional circuits and some accessories. The data acquisition card is NI Elvis II, and the host computer software is LabVIEW.

[0121] Mechanical main body - rectangular box structure. The characteristic of this structure is that the hot bed only moves in the direction of the Z axis, and the nozzle only moves in the direction of the X / Y axis. This structure method can reduce the weight of the nozzle, thereby improving the printing speed and printing accuracy to a certain extent; the printing direction, printing length and printing material are controlled by stepping motors;

[0122] Control circuit. In t...

Abstract

The invention discloses a 3D printing system based on a virtual instrument. An operation method for the 3D printing system comprises the following steps: initial operation: accomplishing the initial operation of the system by using a laminated sequential structure; parameter setting: controlling the upper and lower limits of the thermal resistance of a heating part by using a circulation embeddedcondition structure, setting an event structure in a waiting branch, and editing and modifying the thermal resistance of the heating part via the event structure so as to set upper and lower limit parameters; manual printing: pretreating the system, wherein the pretreatment includes preheating of the system and debugging and setting of the coordinates of a nozzle at the same time, and performing motor operation, extrusion motor operation and temperature control at the same time; and 3D printing: subjecting corresponding 3D object data to layering and slicing, contour optimization, lamellar data processing and other treatment so as to obtain corresponding coordinate information, and controlling a triaxial motor according to the coordinate information so as to realize fixed-point layer-by-layer printing and lamination so as to obtain a 3D object. The 3D printing system provided by the invention realizes 3D scanning and printing via LabVIEW, and is fast in the operation speed of programs,easily debuggable in visual programming and high in printing accuracy.

Description

technical field [0001] With the rapid development of 3D printing technology, the application field and system composition of 3D printing have been greatly developed. In the field of manufacturing, virtual instrument technology has the advantages of fast development and convenient debugging, but there is little construction of 3D printing systems. This deficiency designs a 3D printing system based on virtual instruments. The system uses a rectangular box structure as the hardware basis, and realizes the motor control through the data acquisition card to complete the printing task. The virtual instrument technology uses LabVIEW to build a control terminal to complete the interpretation of 3D files (layer slicing, contour optimization and layer data processing). The coordinate information of each layer is completed through the collaborative processing of software and hardware to complete the printing of 3D objects. Background technique [0002] 3D printing technology is an adv...
