An alternative approach / really cool project on youtube using a laser guided through fiber into a resin bath as the "nozzle" for an fdm-ish style 3d printer https://www.youtube.com/watch?v=UvV2CH5il3Q

Claims 2um layer height and sub 10um feature size - while the people using mosquito bits are claiming 20um line size.

> Recent advances in biohybrid engineering have pushed this paradigm further, seamlessly integrating biotic materials into engineered systems.

This is the first I've heard of the field of "biohybrid engineering" and it sounds pretty cool. As a layman, it makes sense to leverage the micro-scale "manufacturing" capabilities biological systems seem to excel at over our more traditional(?) manufacturing processes.

I'm not sure I like the potentially perverse incentives introduced by using life as a substrate for producing manufacturing components, but then again I don't practice veganism so maybe I'm being hypocritical.

Unfortunately, it's my life's mission to eliminate all female mosquitos (and the proboscis)

just learned :

"To feed, a female mosquito uses a complex mouthpart called a proboscis, which contains six specialized needles (stylets).

Two of these needles are serrated saws that slice through your skin, while two others hold the tissue open. A fifth needle searches for a blood vessel and sucks up your blood, while the sixth simultaneously pumps in saliva containing an anticoagulant to keep the blood flowing. "

sounds like robot-surgeon-manipulator from Star Wars/Trek/etc.
