A 3D-printed microscope, built for £50 and ready in hours, offers a cost-effective way to explore science hands-on.
This £50 3D-printed microscope is causing a scientific stir, and for good reason; the microscope is inexpensive, accessible, and a curious technical achievement. It could be printed, pieced together, and ready for use in less than three hours, according to developers at the University of Strathclyde in the UK.
The design relies on OpenFlexure, an open-source resource for 3D-printable scientific instruments. By combining custom 3D-printed lenses, an affordable camera, a light source, and a Raspberry Pi processor, the team created a lightweight and functional microscope. “Within 3 hours, you go from downloading a computational design to having a fully operational optical microscope,” said Liam Rooney, one of the researchers.
Traditional microscopes often come with steep price tags, with lenses costing hundreds of pounds and complete systems reaching thousands. This innovation shatters those barriers, delivering a practical, fully capable device at a fraction of the cost. The researchers tested its performance by examining blood samples and tissue sections, finding it detailed enough for sub-cellular analysis.
The microscope’s accessibility extends beyond its price. Its components can be crafted using a standard 3D printer, the kind found in many homes and schools. “It’s not just enabling; it’s empowering,” said lead researcher Gail McConnell.

The implications are profound. Experts see this as a tool to democratize science, making advanced equipment available to classrooms and amateur scientists alike. “As a do-it-yourself class project, this could inspire a new generation of students to explore the wonders of biology,” remarked Yann Gambin of the University of New South Wales.
Though the technology is still developing, the potential is clear. Costing £50, this 3D-printed microscope is a prime example of how the power of innovation can open the door to discovery to so many future scientists.
