A research team from the University of Strathclyde has developed a low-cost 3D-printed microscope. This device, which can be assembled in less than three hours, costs approximately $60 and uses transparent plastic lenses printed in 3D. According to the medium New Scientist, the microscope design is based on the open-source microscope platform OpenFlexure and includes a commercial camera, a light source, and a Raspberry Pi for control.
An Economical Alternative to Traditional Microscopes
This 3D-printed microscope has cellular-level imaging capabilities, successfully examining blood and mouse kidney samples. This achievement is remarkable, as the lenses of traditional laboratory-quality microscopes usually cost thousands of dollars. The complete system weighs approximately 6.6 pounds (3 kg), making it portable and suitable for various applications.
Comparison with Low-Cost Microscopes
The cost reduction of this microscope represents a significant advancement compared to existing alternatives. For example, configurations like the Gary Croft microscope camera from 2022 require additional components that raise the total cost to more than $390. The Strathclyde team's version offers similar functionalities at less than a quarter of this price.
Accessibility Benefits for Institutions with Limited Resources
The accessible design of this microscope offers practical benefits for institutions with limited resources. Schools, small laboratories, and medical centers in underserved areas can now access microscopy technology at a fraction of the traditional cost. The device requires only basic materials, a 3D printer, and standard electronic components.
Local and Sustainable Solution
The use of 3D printing technology also solves logistical challenges. Local production becomes possible anywhere there are 3D printing facilities, which could reduce delivery times and transportation costs for organizations in remote locations.
