OpenFlexure, an open source microscope to 3D print

Professional microscopes used in laboratories are usually very expensive, therefore many educational institutions cannot afford them. Along with the DIY trend, we find a new culture of collaboration and sharing that is growing every day. This is the case of the OpenFlexure project, presented by Joel Collins and Richard at the University of Bath in the UK. With the aim of offering an efficient solution to schools, laboratories and universities, these open source microscopes can be created through additive manufacturing, for less than $20.

Producing a high-end microscope can cost hundreds of dollars. However, one of the main advantages of 3D printing is that it allows manufacturing costs to be reduced in small series. Both in terms of initial costs, and equipment maintenance, OpenFlexure is a microscope that is accessible to everyone. For only $18 it covers the cost of the printed plastic, a camera and some fixing accessories. Collins said, “We want these microscopes to be used all over the world: in schools, laboratories, clinics, and even homes, if they want the microscope to play with. You just need to make it and start using it. And we want it to be affordable.”

How do you make your OpenFlexure microscope?

If you bet on this project, here’s what you need to know before you get started. The OpenFlexure is a fully automated laboratory grade instrument (thanks to a Raspberry Pi) with motorized sample positioning and autofocus control. Its design method makes it suitable for small spaces, such as schools or homes. In addition to its main functions, we can customize it with trans and epiluminescence lighting, polarization contrast imaging and epifluorescence imaging. It is designed with an intuitive software interface that allows easy and simple use of the microscope.
