Microfluidics: Which type of 3D printer?

For the first time we shall present a comparative study of three state-of-the-art 3D printers for fabrication of microfluidics including: fused deposition moulding (FDM), Polyjet, and digital light processing stereolithography (DLP-SLA), in terms of microfeature size and accuracy, mass production factors, and their suitability for microfluidics. These are the most frequently used 3D printing approaches for microfluidics and will provide a useful information source for researchers looking to fabricate microfluidic devices with 3D printing technology.
