Abstract
The present invention relates to a process for producing a microfluidic device which involves providing a substrate with a surface and writing a first flowable material on the surface of the substrate. The first flowable material is then solidified to form spacer elements, each with a top surface distal from the surface of the substrate, and a second flowable material is written on the surface of the substrate. A cover having a surface is provided and applied to the substrate, with the surface of the cover contacting the top surfaces of the spacer elements. The second flowable material is solidified to form walls, where the walls, the surface of the substrate, and the surface of the cover form flow channels of a microfluidic device. The resulting microfluidic device is also disclosed.
