【摘要】：以熔融沉積制造技術(shù)中常用的基體材料PLA作為對(duì)象,通過(guò)3D打印實(shí)驗(yàn),對(duì)打印過(guò)程中的因素參數(shù)進(jìn)行優(yōu)化實(shí)驗(yàn)研究。利用單因素實(shí)驗(yàn)法和正交實(shí)驗(yàn)法,以打印時(shí)間和打印尺寸誤差為實(shí)驗(yàn)指標(biāo),選取層厚、打印速度和噴嘴溫度三個(gè)主要因素展開(kāi)實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明,層厚為0.3mm,打印速度為20mm/s,噴嘴溫度為200℃時(shí),可以在保證打印質(zhì)量的情況下獲得最短打印時(shí)間。對(duì)打印效率影響程度由大到小依次是層厚,打印速度,噴嘴溫度,并進(jìn)一步通過(guò)實(shí)驗(yàn)驗(yàn)證。
[Abstract]:In this paper, PLA, a matrix material, which is commonly used in melt deposition manufacturing, is used as the object. Through 3D printing experiment, the factors parameters in the process of printing are optimized and studied. Using single factor experiment method and orthogonal experiment method, three main factors, layer thickness, printing speed and nozzle temperature, are selected to test the printing time and size error. The experimental results show that the shortest printing time can be obtained when the layer thickness is 0.3 mm, the printing speed is 20 mm / s, the nozzle temperature is 200 鈩，
