A fused deposition modeling (FDM) 3D printer extruder was utilized as a micro-furnace draw tower for the direct fabrication of low-cost optical fibers. An air-clad multimode microfiber was drawn from optically transparent polyethylene terephthalate glycol (PETG) filament. A custom-made spooling collection allows for an automatic variation of fiber diameter between ∼ 72 to 397 μm by tuning the drawing speed. Microstructure imaging as well as the 3D beam profiling of the transmitted beam in the orthogonal axes was used to show good quality, functioning microfiber fabrication with uniform diameter and identical beam profiles for orthogonal axes. The drawn microfiber was used to demonstrate budget smartphone colorimetric-based absorption measurement to detect the degree of adulteration of olive oils with soybean oil.
利用融合沉积建模（FDM）3D 打印机挤出机作为微熔池拉丝塔，直接制造低成本光纤。从光学透明的聚对苯二甲酸乙二醇酯（PETG）长丝中拉出空气包层多模微光纤。定制的绕线收集允许通过调整拉丝速度在 ～ 72 至 397 μm 之间自动改变纤维直径。使用微观结构成像以及正交轴上传送光束的 3D 波束轮廓来显示高质量、功能一致的微光纤制造，具有均匀的直径和相同的正交轴光束轮廓。所拉制的微光纤用于演示基于预算智能手机比色法的吸收测量，以检测橄榄油中大豆油的掺假程度。
