An integrated micro-millifluidic processing system

Abstract

An integrated micro-millifluidic processing system based on multimaterial 3D-printing and a maskless lithography system is proposed.

Hydrophilic modification of SLA 3D printed droplet generators by photochemical grafting

“…The smallest feature sizes are achieved using microstereolithography, 11 modied 3D printers and resins, 24 and high-end or custom 3D printers. 14,16,25,26 Channel sizes down to 18 Â 20 mm have been reported with custom setups. 25 Smaller channel sizes are more difficult to obtain with commercial desktop printers.…”

Three-Dimensional Printed Devices in Droplet Microfluidics

“…On the other side, manipulation of droplets in 3D-printed devices including droplet coalescence and sorting has started to be reported. Zhang et al [83] printed a monolithic sorting junction embedded with valves via multimaterial printing (Figure 9(2)). Through pneumatic control of valves to tune the flow resistance, droplet can be sorted into the desired channel.…”

“…Cecil et al [84] also integrated LED on a 3D-printed device for photometric detection. Recently, Zhang et al [83] reported an integrated micro-millifluidic processing system which was manufactured by multimaterial 3DP (Figure 10(3)). Droplet generation, detection, sorting and collection can be achieved in their complex system, which shows 3DP great potentials in developing complicated and integrated system for droplet control.…”
