In order to 3D-print really intricate items, you need a really fine print nozzle. Scientists have discovered that instead of going to the time and trouble of building one, you can simply repurpose a mosquito's existing blood-sucking proboscis.

Don’t fall for it. This is just the mosquito’s desperate plea for a ceasefire. They must be eradicated swiftly and their technology mustn’t be allowed to contaminate our society

"They're onto us!", Big Mosquito.

Finally, mosquitoes are good for something

She’s gone from suck to blow!

For their study, the researchers obtained euthanized laboratory-reared female Aedes Aegypti mosquitoes, stored them in a freezer, then dipped them in a solution of 80% ethanol to sterilize them.

Next, the soft protective outer sheath of each insect's proboscis was detached and discarded. An ultraviolet-curable resin was then applied to the now-exposed rigid section of the proboscis, and hardened by exposure to UV light. The resin-coated proboscis was then cut off of the mosquito's body with a razor blade, forming a nice little rigid tube.

I can't see this process scaling very well.

The question is, if it has to. If it's a nie he product this might be cheaper than inventing something

Yes, take their proboscii! TAKE THEM ALL!

Read the title as “stabby fuckers” and thought that 3d printing community is quite tired of em.

3d necroprintmongers. You keep what you kill and print with it.

Skittish, Toombs.

Pervert meets engineer.... Hours later...it still hurts man!.... Yeah but check out the print quality! Who knew a penis could print a house!

This is actually very cool! I'm surprised by the scale of what they can do with these nozzles.
