Low-cost and straight forward rapid prototyping of flexible microfluidic devices using a desktop digital craft cutter is presented. This rapid prototyping method can consistently achieve microchannels as thin as 200 microm in width and can be used to fabricate three-dimensional (3D) microfluidic devices using only double-sided pressure sensitive adhesive (PSA) tape and laser printer transparency film. Various functional microfluidic devices are demonstrated with this rapid prototyping method. The complete fabrication process from device design concept to working device can be completed in minutes without the need of expensive equipment.
