本論文針對實驗室所開發之下照式手機3D 列印系統為基礎,首次以UV光源開發研究LCD型之光固化系統,並以實驗分析光源因素對於列印之影響情形。
由於為首次採用此UV LED之光源膜組,因此為測量此膜組供電之情形,因此另外以電源供應器來供應光源膜組所需之電壓電流並以POWERMETER儀器來量測供應瓦數所對於的光能量強度。另外再以圖形的曝光實驗,來測試光均勻度、成形性及精度的情形。設計散熱系統,降低此高能量光源模組的溫度,以提高此模組的使用壽命,也防止過高的熱能會影響樹脂固化列印之速度。在機台控制與LCD 面板圖形顯示方面,以樹莓派搭配Python 程式來做傳輸控制,才可做整體的列印測試。
實驗最後也將此405nm波長UV LED光源模組與目前大多數消費者所使用的商用機台 Phrozen及Arkuretta作比較,此三者雖同為 LCD 型式之機台,但採用不同的光源模組,而曝光光源的差異會影響列印的結果,如尺寸精準度、物件邊緣銳利度等之影響。
Based on the 3D printing system developed by the laboratory, this thesis develops the LCD-type photo-curing system with UV light source for the first time, and analyzes the influence of the light source factor on the printing.
Since it is the first time to use this UV LED light source film group, in order to measure the power supply of the film group, the power supply is used to supply the voltage and current required by the light source film group and the POWERMETER instrument is used to measure the supply wattage. The intensity of light energy. In addition, the pattern exposure experiment was used to test the uniformity of light, formability and precision. Design a heat dissipation system to reduce the temperature of the high-energy light source module to increase the service life of the module and prevent excessive heat energy from affecting the speed at which the resin is cured. In the machine control and LCD panel graphic display, the Raspberry Pi with Python program for transmission control, in order to do the overall print test.
At the end of the experiment, the 405nm wavelength UV LED light source module was compared with the commercial machines Phrozen and Arkuretta used by most consumers. Although the three are the LCD type machine, they use different light source modules. The difference in exposure light source can affect the results of printing, such as dimensional accuracy, sharpness of the edge of the object, and so on.
