| Summary: | 碩士 === 中華科技大學 === 電子工程研究所碩士班 === 103 === This thesis is going to develop 3D Printer System which includes 3-axis drive platform and fully automatic LabVIEW execution program. By using Fused Deposition Modeling (FDM) method to print a required 3D object, which executes and piles the layer through designed LabVIEW automatic software, 3-axis position drive platform and ABS Heat Rong material. The 3-axis motion platform is assembled by using three independent “Linear Actuator” which includes a set of high precision Linear Slider, high resolution stepper motor and stepper motor controller. We design a general purpose 3D Printer LabVIEW program for any 3D printer requires user. This Self-Develop LabVIEW automatic program converts the solid model shape 3D position data and commands the 3D stepper motor controller through a set of NI-DAQ I/O Module which duplicates the Solid Model shape step by step, layer by layer automatically. The position accuracy is designed by 0.01 mm in order to produce a perfect print result.
The main part of the thesis is the 3D Printer LabVIEW program which executes the position motion real-time. The program processes the Solid Model 3D data, converts to required accuracy step motion, converts to digital command step, run step motion loop, setting DAQ parameters, adjust motion speed, Z-axis pre-start parameter setting, trace and plot the motion, real-time motion display and graph, 3D Solid Print Graph and data store. The powerful point of this program is friendly Human Interface which can check or inspect any phenomena on time.
A few of print samples are taken place and have a very excellent result. However, the speed is slow due to the Thermal ABS ejection device. Actually, the developing procedure of this system is a complex which includes many subsystem, H/W, parts and modules. Through this self-design H/W and S/W, especially the LabVIEW automatic program, the 3D printer system works very well.
