20.500.12556/RUL-127059 Precision fabrication of flexible microfluidic circuits using direct laser rapid prototyping solution An effective development platform for custom lab-on-a-chip and lab-on-a-foil solutions has been regarded as a missing element for wider adoption of microfluidic technologies in everyday life. We have used a direct laser structuring device combined with CAD-CAM software and have developed an efficient, fast, and precise procedure for rapid prototyping of widely accessible contemporary materials utilized for flexible microfluidics. Utilization of an ultra-short pulsed laser has enabled us to predict and control the laser ablation process on thin low-temperature co-fired ceramics and Kapton foil. We have demonstrated an agreement between the theoretic predictions and experimental data on ablation rates, paving the way to a fully predictive manufacturing process. Our procedure enables an independent control of microfluidic channel shape, depth, and lateral dimensions down to 10 %m, while maintaining an exceptional process quality achieved by a parametrically optimized laser output at single-picosecond pulse durations. Our novel rapid prototyping solution features short turnover times, minimum material waste, no chemical procedures, and a single-step process free of heat-effects. We demonstrate the improvements to the structuring process on a known difficult-to-manufacture herringbone mixer structures inside a micro-mixer chip application. ultra-fast laser processing surface engineering microfluidics laserska obdelava z ultra-kratkimi pulzi površinski pojavi mikrofluidika true false true Angleški jezik Slovenski jezik Članek v reviji 2021-05-14 16:03:09 2021-05-14 16:03:17 2025-03-13 12:56:54 0000-00-00 00:00:00 2020 0 0 Str. 1-8 no. 11, art.115005 Vol. 30 Nov. 2020 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 2020-03-18 2020-07-15 2020-07-30 2021-07-30 544:532(045) 0960-1317 10.1088/1361-6439/aba63f 24398851 RAZ_Mur_Jaka_2020.pdf RAZ_Mur_Jaka_2020.pdf 1 0FB37519BC33780999A548FAE93F471B 61250a52fccabd766fadebc570bd55403303210358289e34c968593645565f8b 0787964a-b4be-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143267 https://iopscience.iop.org/article/10.1088/1361-6439/aba63f 1 1896cf7f-b4bd-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143266 Fakulteta za strojništvo 0 0 0
