An all‐in‐one device for fabricating microfluidic devices is developed by modifying a commercially available liquid‐crystal‐display projector. Micropatterns are formed on photosensitive materials from images that are prepared using personal‐computer software. Desired poly(dimethylsiloxane) microfluidic channels (see Figure) are obtained rapidly without the need for expensive photomasks and light sources.
