I was gonna say that **** needs to be on thingiverse lol.

That was my first reaction. Then I read the story and the blog it came from and looky look. It's all about thingiverse. Love it!

3D printing changes EVERYTHING!

Can't wait till it compares to the injection method.

With a 3D printer, a lathe, a drill press, a cnc and a few other things, you are unstoppable!

It's absolutely amazing how fast the hobbyists are surpassing the professionals. This is like particle physics back in the day. The hobbyists are making the biggest contributions.


To make a decent prosthetic on a home workbench is amazing! I love where we're going with this. My ideal future involves mirco manufacturing based on immediate needs.

Oh I need a sprocket this big, cool I'll just print that **** out.

It's not weird. It's smart!!! And I stand by that.... Suckas!!!! :p




But yes, I'm an open source guy. I'm a capitalist, and many don't see how these two fit together. But I do. And I suspect a few of you do as well. I'm not saying I'm so smart, I just have been fortunate to have met the right people who were able to explain these things easily. I respect IP to an extent, but the old laws are no good. You got these software patent trolls going nutts extorting anyone they can because they can take advantage of laws that regulate something the lawmakers clearly didn't understand. The turn around in the industry far exceeds the limits on patent law. So yay, I can use this in 20 years? Who ****ing cares, in 20 years not only will there be 43786487 diff ways to do the same task, but it will be obsolete as a singular idea by then. The real scary part is that America is falling behind in the sciences. The next generations may not be that much more knowledgeable than the ones we have now. That's what you get when you cut funds for the words largest accelerator in Texas. HUGE mistake.


And for the record, Syn likes ***** too. Ahem, SJ, MK.... :rolleyes:

Oh look I'm turning into a 3rd person douchebag! :p

Syn likes many things!!! :D


You're all weird, I'm normal!!!

By the way, that equation leaves out a few VERY important factors. Care to guess what they are?

[Lucas]

No I didn't! I just think that website is neat. I was going to divide Mickey Mouse by Bugs Bunny....I'm on my phone right now and it won't load that site. I just remember only looking at the distance to Saturn and something about an suv. I'm sure there's plenty missing. But I'll look when i get a chance at work.

In the near future, having an artificial limb will be an advantage. Imagine the sensory input we will be able to get with these prosthetics. It won't be long till humans are able to directly experience some of the things we can only sense through machines. This is changing the fundamentals of what it is to be human. I realize this scares people, but then people are always scared of things they don't understand. Another reason to make scientific literacy compulsory.

Last year there was a live demo of a printed kidney on TEDtalks.

It will be awhile before they are actually approved to test on humans, but so far so good.

They are working on printing all sorts of organics, including some really dangerous nasty stuff like anthrax and the cures for these nasty things. The desktop versions aren't as far off as some may think.

I wonder if you get the CAD files too. That would help justify the price. The actual printing is pretty cheap.

3D scanning is really starting to become affordable. Limor Fried held a contest to hack the Kinect and people did some amazing stuff. At first microsoft was ****ed, but it wasn't long before they saw this new markets potential and now they encourage hacking their products. Well, not all of them. But they aren't like Apple with the whole tamper proof everything. There is a saying in the hacking community... You don't really own something until you void the warranty ;)

I have a scanner made from two Kinects in the works. Early stages. When it's done maybe I'll post up some of the work.

The First 3D-Printed Gun Has Been Fired (VIDEO) (http://www.huffingtonpost.com/2013/05/06/3d-printed-gun-fired_n_3222669.html)
The Huffington Post | By Alexis Kleinman Posted: 05/06/2013 10:48 am EDT | Updated: 05/07/2013 2:28 am EDT

http://i.huffpost.com/gen/1121973/thumbs/s-3D-PRINTED-GUN-large.jpg?7
The first 3D-printed gun in action.

The world's first 3D printed gun fired its first shot on Sunday, according to this video released by Defense Distributed, the controversial company pushing for D-I-Y weapons.

Cody Wilson, of Defense Distributed, the company behind The Liberator, told the BBC that he is not concerned with the potential harm the gun could cause. He said, "I recognise the tool might be used to harm other people - that's what the tool is - it's a gun. But I don't think that's a reason to not do it - or a reason not to put it out there."

Defense Distributed's goals, as displayed on its website, are the following:

To defend the civil liberty of popular access to arms as guaranteed by the United States Constitution and affirmed by the United States Supreme Court, through facilitating global access to, and the collaborative production of, information and knowledge related to the 3D printing of arms; and to publish and distribute, at no cost to the public, such information and knowledge in promotion of the public interest.

Though 3D printing is still a fairly nascent technology, its growth is expected to be widespread. Staples expects to offer them in stores next month. Anyone interested in building a gun, then, could go to Defense Distributed's site and download the CAD file to get started.

The worst part? It's legal. Donna Sellers of the US Bureau of Alcohol, Tobacco, Firearms and Explosives, told the BBC that "a person can manufacture a firearm for their own use" in the U.S.

The horror of 3D printed guns stands in sharp contrast to some of the more amazing benefits 3D printing could bring, including the ability to revolutionize medicine. Is it worth the risk?

A gun undetectable through metal detectors. This will work out well.

[sanjuro_ronin]

Its a fascinating thing for sure.
One of those "just because we can doesn't mean we should" thing probably.
That said, how economical is it?
I mean, you still have to buy the material and the machine to make the parts, right?
So, how much would it cost?

Less than $2k. Possibly less than $1.5k

[Syn7]

A gun undetectable through metal detectors. This will work out well.

That is the law that will be used here. Short term anyways. It is illegal to possess an undetectable firearm. In the US, that is. In Canada it is illegal to own ANY gun that you don't have a permit for.


Ok, so... tech details. It's probably made out of ABS. The printer that one was printed on is roughly 8 grand. A $2000 3DCUBE will NOT cut it here. There is one piece of metal in there and then there are the bullets. We cannot print plastic shells. There are non metal shells out there, but they are not cheap and they are not practical. Not yet anyways.

While I recognize the dangers here, we have to accept this reality. It won't be long before people can do this on a desktop 3D printer. Illegal or not, people will trade CAD files. These things are here to stay.

I would be far more concerned with the bioprinters. Download the CAD for aids, make it airborne or something crazy like that. Print, send, ****ED!

This is already a reality. It won't be long till it's affordable. The good outweighs the bad. No law will fix this. It's a social issue. We will either survive our own technology or we will not. If we don't, we deserve it anyways. I'm at peace with this. If we want to move to the next level, we have to go there. That's just how it is.

[Syn7]

It's also worth noting that they have been printing lower receivers now for awhile. That is the part that is regulated. You can just go anywhere and buy the rest and slap it together yourself. Back in the day people would machine their own lowers, buy the rest and make an unlicensed gun that way. Now you print those parts then assemble what you printed.

Interesting perspective.

[David Jamieson]

In Canada it is illegal to own ANY gun that you don't have a permit for.

not actually true. Farmers can grandfather their arms to their family. I know guys who have several grandfathered firearms, no permits etc. But they are farm boys and in the rural areas, gun control isn't an issue at all.

It's in the cities where the issue lies. I have no problem with rural folk having firearms. They need them after all. people in the cities? Why do they want guns? self protection? Why are you paying a police force? Why do you have alarms on your house? etc etc. The only guns that are useful in a big city are those used by criminals and police and the rest are just a source for criminals to steal.

In my opinion.

That is the exception to the rule. There will be no grandfather loopholes as far as printed firearms are concerned.

I like guns. I have guns. I learned to use guns at a young age. I was around it since birth. Around 10 or 11 I got to start shooting myself. At 14 I was walking through the forest alone for two three days at a time with two guns. I'm lucky I guess. I had reasonable sensible parents and extended fam. I know other families that teach their kids to shoot and they are all idiots and it's scary that they are so well armed. Knuckledraggers for sure. While regulation is reasonable IMO, it's not and never will be a complete solution to the problem. We are just going to have to get used to the idea that anyone will be able to print a gun in the NEAR future. Just how it is... Time for us to grow up a lil. Hopefully it's not too painful.

[mawali]

I would have thought with the new 3D printer technology, the impetus would be on socially beneficially items as opposed to guns. My bad!
Just like when the camera was developed, Hustler came out the next day!:D

I bought the first issue! hehe

Yeah, they are a bit of a process and a lil more work than with ABS but still pretty cool. Unfortunately they don't make a very strong product... yet. Really good for some things, really bad for others. Like to print the liberator in metal would be a bad idea. That's not far off though.

3D-Printed Foot Lets Crippled Duck Walk Again (http://mashable.com/2013/07/02/3d-printed-duck-foot/)

By Vignesh Ramachandran5 hours ago

Born with a backwards left foot last November, Buttercup the duck had never been able to walk normally. But that was until Sunday, when thanks to 3D printing technology, Buttercup was fitted with a custom-designed silicone foot that has him up and walking like a duck.

The folks at the Feathered Angels Waterfowl Sanctuary in Tennessee have been taking care of Buttercup and chronicling his journey on Facebook. They worked with 3D-printing company NovaCopy to print a replica of Buttercup's sister's left foot. Using that copy, the sanctuary was able to mold a silicone foot for Buttercup that could fit perfectly.

On Sunday, the silicone foot was attached to a custom-fit sock on Buttercup using a nylon retaining screw, and the duck was able to walk again.

Ten 3D-printed houses to be used in Shanghai's Qingpu district (http://shanghaiist.com/2014/08/26/3d-printed-houses-to-be-used-shanghai-qingpu-district.php)

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-1.jpg

The 10 3D-printed houses made by a Chinese company from recycled material earlier this year were officially put into use on August 21 in Shanghai's Qingpu district, Tencent News reports.

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-2.jpg

The houses aren't very big, each one measuring around a dozen square meters. No signs of bricks and tiles can be seen on the houses and the tallest one is no more than two stories.

The components were printed with a special "ink" made from industrial construction waste.

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-3.jpg

A simple drawing, a computer and an ample amount of "ink" can create 10 of these 3D houses in one day. The inventor of this technology said that the printing process is their "top secret".

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-4.jpg

The 3D printer, measuring 32 meters long, 10 meters wide and 6.6 meters deep, was assembled in a factory in Suzhou. The bottom area is as big as a basketball court with a height of three stories. The length of the printer can be stretched out as far as150 meters.

The 3D houses were printed in Suzhou and then moved to Shanghai.

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-5.jpg

http://shanghaiist.com/upload/2014/08/shanghai-3Dprintedhouse-6.jpg

The houses are now being furnished and will be ready for move-in after the windows, wires, floors and furniture are put in.

The 3D-printing technology is environment-friendly and costs 50 percent less than traditional construction, according to reports. The 10 houses costed 4,800 USD to make.

It won't be long before most structures are manufactured on site by ginormous CNC's. At first it will be an assembly thing with humans stepping in at various stages, but eventually it will be mostly raw materials delivered to the site. Back in the trailer, expand, load, go. It will work day and night till the job is done and the only staff on hand will be for maintenance and incidental deficiencies. It will put a lot of people out of work, but we will adapt just as we have as we've moved away from our agrarian roots. In closing, make sure your kids are tech savvy, they're gonna need it.

Chinese doctors to rebuild man's skull using 3D-printing technology (http://shanghaiist.com/2014/08/28/chinese-doctors-to-rebuild-mans-skull-using-3d-printing-technology.php)

http://shanghaiist.com/attachments/katienelson/3d-printed-skullmain.jpg

A 46-year-old farmer who lost half of his skull in a construction accident will undergo an operation at the Xijing hospital in Xi’an, Shaanxi province to replace the missing part with a titanium implant made with 3D-printing technology.

http://shanghaiist.com/attachments/katienelson/3d-printed-skull3.jpg

The patient, surnamed Hu, was doing construction on a house in Zhouzhi county last October when he fell from the third floor. He survived, but the left part of his skull was severely crushed and needed to be removed. The accident also impaired his vision and speech.

http://shanghaiist.com/attachments/katienelson/3d-printed-skull.jpg

Today, Hu is undergoing the operation to fill in the missing skull with a 3D-printed titanium metal hood.

Last May, a 22-year-old Dutch woman received the world's first 3d-printed implant for her skull.

Yesterday, we reported that the first-ever 3D-printed vertebra was implanted into a 12-year-old Beijing boy suffering from a tumor.

http://shanghaiist.com/attachments/shang_shanghaiist/big-head-1.jpg

A three-year-old girl suffering congenital hydrocephalus survived a grueling 17-hour surgery to replace her cranium with a 3D-printed titanium mesh, making this the first successful surgery of its kind in China.

The operation was carried out at the Second People’s Hospital of Hunan Province on July 15, according to CCTV News. The toddler, nicknamed Hanhan, is now staying in an intensive care unit for post procedure observation and further treatment.

Around 85 percent of the child's skull was filled with cerebrospinal fluid, causing her head to swell nearly four times the size of a normal infant. Her tiny body could not support her abnormally sized head, and she's had to remain lying in bed since September of last year.

http://shanghaiist.com/attachments/shang_shanghaiist/big-head-2.jpg

On May 17, Hanhan was transferred to the Hunan hospital where she underwent a two-month treatment. The situation was improving but her skull was getting weaker. Doctors decided that she needed to undergo surgery to save her life.

http://shanghaiist.com/attachments/shang_shanghaiist/big-head-3.jpg

Neurosurgeons successfully removed a large piece of skull from the toddler's head and replaced it with a 3D-printed titanium mesh.

Around 15 kilos of fluid was drained from Hanhan's brain in an operation likened to "opening an egg without damaging the egg membrane and keeping the white and yolk inside the egg".

http://shanghaiist.com/attachments/shang_shanghaiist/big-head-4.jpg

Tan Lihong, the president of the hospital, said the hospital performed the surgery free of charge, and plans on further organizing donation charities and volunteer activities to help the girl with her remaining treatment.

A Chinese funeral home is using 3D printing to manufacture spare parts for dead bodies, state media has reported.

The Longhua funeral home in Shanghai is thought to be the first in China to use 3D printing in this manner.

“Sometimes bodies are brought to the funeral home that have been damaged or are incomplete in some way,” said a report on CRIEnglish.com. “The 3D printing technique enables a more accurate and easier repair process.”

3D printing uses successive layers of materials to create a three-dimensional product. Conceptually, the technology could be used to create limbs, hair or facial features that might be damaged on a corpse, or missing from it.

According to Thursday’s article, use of 3D technology for a face recreation would cost about 4000-5000 yuan, or £430 to £540.

Some funeral homes in the US and Europe have also employed 3D printing technology, but not for the deceased. One company, UPD Urns, has produced a video to attract customers to its 3D-printed cremation urns and busts.

3D printing is booming in China. Foreign companies dominate the market for 3D manufacturing, but Chinese companies are catching up, according to a recent report by International Data Corp, a market analyst.

What an odd application of this tech...

This Medieval Italian Man Replaced His Amputated Hand With a Weapon (https://www.sciencealert.com/medieval-lombard-man-amputated-arm-knife-prosthesis)
Badass.
MICHELLE STARR 13 APR 2018

Archaeologists have found a fascinating puzzle in the shape of a man's remains dating back to medieval Italy. It looks like this guy went through life with a knife attached to his arm, in place of his amputated hand.

The skeleton in question was found in a Longobard necropolis in the north of Italy, dating back to around the 6th to 8th centuries CE. Hundreds of skeletons were buried there, as well as a headless horse and several greyhounds, but this particular skeleton stood out.

He was an older male, aged between 40 and 50, and his right arm had been amputated around the mid-forearm.

The researchers, led by archaeologist Ileana Micarelli of Sapienza University in Rome, determined that the hand had been removed by blunt force trauma, but exactly how or why is impossible to tell.

"One possibility is that the limb was amputated for medical reasons; perhaps the forelimb was broken due to an accidental fall or some other means, resulting in an unhealable fracture," they wrote in their paper.

"Still, given the warrior-specific culture of the Longobard people, a loss due to fighting is also possible."

On closer examination, the ends of the bone showed evidence of biomechanical pressure - reshaping of both bones to form a callus, and a bone spur on the ulna. These are consistent with the sort of pressure that might have been applied by a prosthesis.


Further evidence on the skeleton supports this hypothesis. The man's teeth showed extreme wear - a huge loss of enamel, and a bone lesion. He'd worn his teeth so far down on the right side of his mouth that he'd likely opened the pulp cavity, causing a bacterial infection.

What's that got to do with a prosthesis? He was probably using his teeth to tighten the straps that held it in place.

https://www.sciencealert.com/images/2018-04/tooth-wear.jpg
Dental wear and the bone lesion. (Micarelli et al.)

His shoulder showed evidence of this too - it had developed a C-shaped ridge of bone from holding the shoulder in an unnaturally extended position to tighten the prosthesis in his mouth. The only way this ridge could have formed is if the movement was frequent.

All the other male burials with knives at the site had their arms and their weapons laid at their sides. But not this guy.

He had his right arm bent at the elbow, the arm laid across his torso. Next to it was a knife blade, the butt aligned with his amputated wrist. Also at the amputation site, archaeologists found a D-shaped buckle, and decomposed organic material - most likely leather.


This suggests a leather cap over the amputated limb, a buckle used for fastening - and a knife attached to the cap, although the purpose is unclear. However, given the advanced healing of the bone, it is clear the man lived for a long time after his hand had been amputated.

"This Longobard male shows a remarkable survival after a forelimb amputation during pre-antibiotic era. Not only did he adjust very well to his condition, he did so with the use of a culturally-derived device, along with considerable community support," the team wrote in their paper.

"The survival of this Longobard male testifies to community care, family compassion and a high value given to human life."

The team's paper has been published in the Journal of Anthropological Sciences (http://www.isita-org.com/jass/Contents/ContentsVol96.htm), where it can be read in full.

Ghost Gunner Gun Making CNC Machine : DOJ Settles 3D Printed Gun Case, Ghost-Gun Genie Is Out Of The Bottle

U.S.A. –-(Ammoland.com)- Cody Wilson had a goal. That goal is to make all gun control irrelevant. Starting on July 27th, 2018, his goal will come to fruition.

The Department of Justice has settled in a landmark case that will allow Defense Distributed to distribute the source files online for 3D printed guns up to .50 caliber. With 3D firearms printing becoming cheaper and better every day this changes the landscape of the 2A battle. The “ghost-gun” genie is indeed out of the bottle as 3D source files will now be free game for all to download.

In 2013 Wilson and Defense Distributed released the Liberator which was the world's first 3D printed gun. Wilson named the Liberator after the famous single shot World War II pistol that the Allies dropped over Nazi-occupied France. Only a couple weeks after releasing the plans the government demanded that he pull them down from his site claiming the plans violated export regulations as defined in the International Trade in Arms Regulations (ITAR).

The government asserted that Wilson was exporting guns without a license. The government viewed the files that Wilson uploaded to the internet the same way as if he would have exported physical firearms to other countries. Wilson disagreed with this assertion and decided to sue the government on First Amendment grounds for the right to distribute the 3D printed files online for anyone to download.

The first set of lawyers that Wilson hired told him that the case was hopeless, and he would not be able to win. Wilson was unwilling to accept that verdict, so he fired his attorneys and hired new ones working with The Second Amendment Foundation who believed that he could win. It was a David vs. Goliath situation. The suit took five years and nearly a million dollars, but Wilson was vindicated.

The nonprofit Defense Distributed also makes the Ghost Gunner 2 CNC Machine which AmmoLand has reviewed in the past. The Ghost Gunner 2 is a mini CNC machine that lets the user mill out 80% lower receivers for the popular AR-15 and 80% 1911 pistols with just a click of a mouse. The Ghost Gunner 2 enables anyone to make a non-serialized gun in their basement. Defense Distributed started making the Ghost Gunner 2 for the purpose of funding the lawsuit against the DOJ. Defense Distributed has sold around 6,000 of the CNC machines nationwide.

In the settlement, the government also admits that semi-automatic rifles including the AR-15 are not inherently military weapons.
This admission is a blow to the false narrative pushed by some members of Congress and anti-gun groups that the AR-15 and other modern sporting rifles are “weapons of war.”

That acknowledgment could have massive ramifications throughout the country in states that banned modern sporting rifles through so-called “assault weapons bans.” Those bans are now on shaky legal ground thanks to the government admission about semi-automatic rifles in the settlement.

Cody Wilson, a self-proclaimed crypto-anarchist, told Wired he had planned to release the files no matter how the lawsuit went, if Hillary Clinton had have been elected president and decided to crack down on our Second Amendment rights as listed in the Constitution.

Wilson encourages people to download the files and make improvements. He sees the data as a starting point to something better. The 30-year-old took on the government and won a significant battle not only for our Second Amendment rights but also for our First Amendment rights.

Defense Distributed will distribute the files on the website, defcad.org. Wilson describes defcad.org as a GitHub (a software development site) for guns. Currently, the site lets users sign up for a mailing list to get notifications on site news.

AmmoLand has reached out to Wilson, whom we have interviewed for the site, but as of the time of this writing, Wilson has not returned our request for comment.

It's 86 feet long and was created entirely with a 3D printer. Shanghai is now home to the world's longest 3D-printed concrete bridge, produced by a team from the Tsinghua University School of Architecture in Beijing.
The pedestrian crossing was modeled on the famed Zhaozhou Bridge, which was built between 589 and 618 in Hebei province, northern China, and is the country's oldest standing bridge. That crossing was made from limestone slabs, while the new structure, found in Shanghai's Baoshan district, was created using far more modern construction techniques.

The record-breaking bridge may not be as beautiful as its ancient predecessor, but what it lacks in aesthetics it makes up for in technology -- it was produced in just 450 hours and cost just a fraction of the usual price.
Designed by professor Xu Weiguo, the bridge's body consists of 44 3D-printed concrete units, each measuring about 3x3x5 feet, while the flowing sides are made from 68 separate concrete slabs.
The bridge was printed piece by piece, using two robotic arms and technology developed by Xu. Tsinghua University claims the project cost a third less than a standard bridge of equivalent size.
Before construction started, a smaller model was created to test the design's integrity and prove its ability to support pedestrians. The bridge also contains systems that monitor internal stress and strain, helping its designers to track the structure's condition in real time.
How artificial intelligence and robots can change your living spaces
The world's first 3D-printed concrete bridge opened in the Netherlands in October 2017, measuring a comparatively small 26 feet. Created by Eindhoven University of Technology in the town of Gemert, the structure was designed to carry cyclists and comprises about 800 layers of concrete.

3D-printed vegan salmon hits the European market (https://www.businessinsider.com/3d-printed-vegan-salmon-hits-european-market-2023-10)

Revo Foods is the first company to sell 3D-printed vegan salmon fillets, now available in Europe.
Some $400 million has poured into startups making seafood from plants and fish cells.
Entrepreneurs said alternative seafood could reduce overfishing and microplastic pollution.

The market for 3D-printed products includes homes, furniture, and footwear. Now we can add salmon to the list, at least in Europe.

The foodtech startup Revo Foods in September became the first company to sell 3D-printed vegan salmon filets in select grocery stores in Vienna, Austria, and opened an online shop that ships the product to most European countries this month.

"It flakes very nicely into layers just like salmon," Robin Simsa, the CEO of Revo Foods, told Insider. "It also has a similar taste, but like any meat alternative, it's not 100% the same."

This marks a milestone for the nascent alternative-seafood industry, which is testing an array of ingredients and technologies to make products that don't harm ocean ecosystems. Some startups are developing plant-based options, while others are growing fish cells in a lab. For its part, Revo Foods' 3D printer layers "mycoprotein" made from mushroom roots with plant-based fats to mimic the texture of real salmon.

Investors have poured upward of $400 million into the alternative-seafood startups in recent years — including $7 million in Revo Foods. But no company is making massive amounts of it yet. And the biggest question remains largely untested: Will people buy it?

Over the past several weeks, Simsa said Revo Foods' vegan salmon has sold out within hours of hitting store shelves. But many of the comments below a YouTube promotional video were critical of the premium price and the idea of printing food.

Revo Foods sells 130 grams, or about 4 ½ ounces, of its vegan salmon for 7 euros, or about $7.

"​​Why would I eat fake salmon that's more expensive than real salmon?" one commenter asked. Another said they'd rather be in a nuclear apocalypse than eat the vegan filets. The reactions were more positive on Instagram, however.

Simsa said the price will drop as Revo Foods automates more steps in the process outside of 3D printing and produces larger volumes. He acknowledged that people are skeptical of the technology but said it isn't unlike other industrial machinery that already makes chocolate and snacks. Barilla is already selling 3D-printed pasta.

There's also the sustainability angle.

Salmon is considered one of the healthiest things to eat and fish in general have a much lower carbon footprint than beef, a well-known contributor to the climate crisis because of methane emissions from cattle and the vast amount of land required to raise them.

Still, around one-third of global fish stocks are overexploited, according to the United Nations. And fishing nets are a major source of ocean microplastics, which scientists say are increasingly being found in humans.

"Ultimately, people want to be excited about a product. We have to capture their imaginations," Christopher Bryson, the CEO of New School Foods, told Insider. His startup is developing its own plant-based whole salmon filet using a novel freezing technology and has raised $12 million.

"If people made decisions based on health and the planet, we'd all already only be eating tofu," Bryson said.
