A team of physicists and engineers at the University of Strathclyde, in Scotland, working with a colleague from the University of Glasgow, has developed the means for 3D printing a microscope, including the lens, for under $60. In their paper posted on the bioRxiv preprint server, the group describes how they came up with the plans for the microscope and notes that the end result has a resolution strong enough to make out individual blood cells in test samples.

    it was possible to print quality microscope lenses using a photopolymerizing clear resin on a Mars 3 Pro printer. In developing the specifications for their lenses, they followed those of the Edmund Optics 12.7 mm diameter plano-convex lens, which has a focal length of 35 mm

    I didn’t open the paper to read more, but that’s the important bit if you’re curious like me.

        The paper mentions 2 printers and quite a few other pieces of equipment for clearing the lenses, which is kinda what I figured the catch was going to be.

        Edit: what I could see coming from that is this new manufacturing method bringing costs down across the board, and they’ll almost certainly be individuals that go all the way through with it as it’s described here, along with making improvements along the way. I just think the headline is inviting disappointment.
