Engineers repurpose a mosquito proboscis to create a 3D printing nozzle
- backprop1989 11mo agoCalling it a necroprinter is equal parts ominous and spectacular.
- metalman 11mo agohopefully the name will stick, as it realy is ,,ominous and spectacular ,,and will get people thinking about what might come next
- faidit 11mo agodidn't elon say that hands and fingers are the hardest part of making robots? peasants under technofeudalism don't really need those parts anyway, since we'll be evolving into vat people with brain chips soon in the new necropia
- exasperaited 11mo ago> didn't elon say that hands and fingers are the hardest part of making robots? Not a problem for a dancer in a robot suit though.
- debesyla 11mo agoReminds me of something from Warhammer 40k universe. Next someone is going to put ChatGPT helper inside a human skull, probably :V

- profsummergig 11mo agoIn the future, when humans die, their neurons will be sold and repurposed in local AI's.
- nkrisc 11mo ago“Oh, look, he’s dead. Let’s sell his neurons.” The neuron harvester says as he wipes the blood from his knife.
- alterom 11mo ago>In the future, when humans die, their neurons will be sold and repurposed in local AI's. In the future, humans won't need to die to have their neurons sold off as hardware for the AI. Incidentally, that's the original idea behind the movie Matrix: humans are used as CPUs for the Matrix. The word is, the idea was too advanced for the audience and was dumbed down into "humans are batteries". I guess we'll have to treat Morpheus as unreliable narrator, or assume that the real energy in the future is compute, and suddenly the movie makes 100x more sense.
- dmurray 11mo agoAnd then you find that the inks they've tried it with are solutions of cancer cells. The necroprinter prints cancer.
- b3lvedere 11mo ago"Hi, i'd like some dead nozzles for my necroprinter please. What do you mean i can only pay with SoulCoin?"

- amelius 11mo agoIt is silly. By that standard, your leather shoes should be called necrofootwear.
- viraptor 11mo agoI mean... Yeah? Reminds me of the Metalocalypse on Christmas trees: "It's like having a rotting corpse in your house, but the corpse of a tree, you know? It's kind of baddass. It stands and then you humiliate it even further by hanging ornaments all over it," You can make anything metal if you try hard enough.
- amelius 11mo agoBut right now we're addicted to plastic.
- kragen 11mo agoI am definitely going to do this now. But shouldn't the rest of the word be Greek too? Let's put on our necropodes to go for a walk? Or necropapoutsi? That's not a classical root.
- kragen 11mo agoThey say the mosquito proboscis has a 20 μm inner diameter, "100% finer" than commercial alternatives (presumably meaning half the diameter). Not having read the paper, I'm guessing it can't handle 210° molten PLA.
- nbadg 11mo agoFrom TFA, they're using it to print bioinks. Think scaffolding for cell cultures. At these kinds of physical scales, biology is almost certainly a much larger market than mechanical applications. A 20 um line width (slightly less than one thou for US folks) is certainly a tolerance you might encounter on a drawing for subtractive manufacturing, but for addative, feature sizes that small will be strength limited.
- kragen 11mo agoMechanical applications at that scale are not well developed, but that doesn't mean their potential is small. Member sizes below the critical diameter for flaw-sensitivity are crucial to the hardness and durability of, for example, human teeth and limpet teeth, as well as the resilience of bone and jade. Nearly all metals, glasses, and ceramics are limited to a tiny percentage of their theoretical mechanical performance by flaw-sensitivity. Laparoscopes that require smaller incisions are better laparoscopes. Ideally you could thread in a biopsy-needle instrument through a large vein to almost anywhere in the body. Visible-light optical metamaterials such as negative-index lenses require submicron feature sizes. I know a research group that is gluing battery-powered RFID transponders to honeybees. Electrophoretic e-paper displays are orders of magnitude more power-hungry than hypothetical MEMS flip-dot displays. We just don't have an economical way to make those. And of course MEMS gyroscopes, accelerometers, and DLP chips are already mass-market products. There's still a lot of room at the bottom, even if EUV takes thetakes purely computational opportunities off the table.
- BlaDeKke 11mo agoI can’t wait for MEMS flip-dot displays.
- sirobg 11mo agoI wonder if at scale this will lead to mosquito farms or to mosquito extinction in nature. Of course I suspect it will be the former but the latter is way funnier. We've been stuck with these insects for a while. It would be so funny that the solution to get rid of them was in fact the same that wiped out many species before: over exploitation of natural resources. cc https://tornyol.com/ https://tornyol.com/
- thaumasiotes 11mo agoI mean, ideally it would lead to both. We can wipe out the farmed mosquitos when we find something else that produces similar tubes. Our most successful efforts at wiping out wild mosquitos, though, don't produce useful corpses. So I don't think it's particularly realistic for high industrial demand to lead to mosquito extinction anyway.
- ThrowawayTestr 11mo agoBreeding mosquitos is way easier than capturing them.
- agumonkey 11mo agoAnd then there are farm to breed mosquitos in order to neuter others
- unwind 11mo agoThis is cool and great and all, but isn't it a bit ... stretched to motivate this by the fact that the nozzle is biodegradable? I mean for a printing nozzle with an inner diameter of 20 µm, how much material would be wasted if it was made out of plastic or metal? I get that no such nozzle is available and/or easily made, but shouldn't that be the point of the invention, rather than "yay, it's biodegradable so we save a microgram of plastic/metal"?
- dmurray 11mo agoYes, it's silly. They surely use orders of magnitude more consumables (latex gloves, plastic bottle tops for chemicals...) in preparing a batch of mosquito proboscides than the hypothetical nozzle would take up. The university's marketing department has been instructed to emphasize sustainability in its press releases, and the website reporting it has, like most news organisations that have survived, made the choice not to hire journalists with critical thinking skills but to have them rephrase press releases.
- froh42 11mo agoI'm so disappointed they didn't print a tiny benchy in their videos.
- bolangi 11mo ago> Its inner diameter is 20 micrometers, which is about 100% finer than the best commercially available tips. "100% finer", who uses language like this? I don't even know what it means. How about "half the diameter"?
- wlesieutre 11mo agoI can only assume the new nozzle is infinitely fine
- dtgriscom 11mo agoIt's a new world, where politicians claim they can cut prices by hundreds of percent.
- Terr_ 11mo agoIf I had my 'druthers, all percentages would be replaced by multiplication factors. I would especially eradicate percentages combined with modifiers like "more", "less", "grows by", etc., which easily leads to awkward or impossibly ambiguous statements. In other words, kids won't learn "150% more" but instead "2.5x". Nothing will be described as "shrinks by 30%", it'll just be 0.70x. While advertisers/marketers may love percentages for tricking people with a Big Happy Number, mathematically they are extra work at best, and sometimes they just ruin everything like this "100% finer" nonsense."
- pennomi 11mo agoFine means small, and it’s not a terribly uncommon definition, especially when talking about materials, like paper or textiles.
- kbelder 10mo agoSo "100% smaller". I'm not sure it improves the sentence much.
- danybittel 11mo agoIf you want to see a mosquito and it's proboscis up close, I recently scanned one into a gaussian splat: https://superspl.at/view?id=b4cbf5d6 https://superspl.at/view?id=b4cbf5d6
- th0ma5 11mo agoSick!!
- simgt 11mo agoI had no idea a DSLR with a macro lens could get you this close. Would you mind sharing more about the process? The bee is even more impressive: https://superspl.at/view?id=ac0acb0e https://superspl.at/view?id=ac0acb0e

- AndrewKemendo 11mo agoThat is a really great scan!
- literalAardvark 11mo agoThat's an incredible technique I had no idea about, thank you
- fuzzythinker 11mo agoThanks, interesting site. Tried to scroll down to find the "about" link but inf-scrolled. /about didn't work too.
- injidup 11mo agoWhy the word "sustainable" in here? It's like every product pitch these days needs the word "sustainable" in it to pass legal.
- knowitnone3 11mo agowonder if graphene nanotubes would work here. "Single-walled carbon nanotubes have diameters around 0.5–2.0 nanometres"
- stevemadere 11mo agoThere’s a long history of using various organs from dead animals as parts/tools in agricultural and industrial processes. This is one of the smallest scale cases I’ve heard of, but not nearly as weird or innovative as it sounds at first blush. People have long been making analogous use of stomachs, intestines, even skulls if you go back far enough.
