UC Berkeley is a leader in 3D printing. From creating a prosthetic hand for an 8-year-old girl to a “smart cap” that senses spoiled food to large-scale cement buildings, engineers and designers on campus are pushing the technology to the limits, using it in ways never seen before.
The technology got its start on campus about a decade ago and continues to grow. With this surge in popularity has come a surge in waste. Now, with more than 100 printers on campus, at least 600 pounds of trash is generated each year.
But Nicole Panditi, a mechanical engineering student, and Scott Silva, and environmental sciences student, have a solution.
Panditi and Silva, who work for the Student Environmental Resource Center, and Ph.D. student Mickey Clemon are leading the 3D Printer Filament Reclamation Project to decrease the amount of plastic waste made by 3D printers on campus. They’re creating a campuswide system that takes used 3D printer plastic, grinds it up, melts it down and produces a new spool of plastic that can be used again in the campus’s 3D printers.
Although there have been several smaller student efforts to recycle 3D printer plastic on campus, and some campus labs buy recycled filament, this would be the first time Berkeley had an infrastructure to recycle all the 3D plastic waste on campus, something Panditi says will be essential as it becomes more and more popular.
“It’s my personal goal to reduce inefficiencies in 3D printing so that the tech industry can reach its full beneficial potential without being haunted by mountains of ugly waste,” she says.
The project is spearheaded by the Zero Waste Research Center, which aims to decrease waste on campus and to find new, creative ways to reuse and recycle items, particularly plastics. Lin King is the center’s manager. He says creating a closed loop of 3D printer plastic waste on campus not only decreases the amount of plastic waste, but also lightens the carbon footprint.
“The idea is that the plastics would never have to leave campus,” says King. “We would provide Berkeley-produced recycled filament and any discarded items would be sent right back to us.”
As 3D printing becomes more mainstream, one area where it will prove useful is mass customization, says mechanical engineering professor Tarek Zohdi, the lead faculty member of the project. “One very special niche is for biological implants for prosthetics - for children in particular. Children who have lost a limb need new prosthetics designed for them as they start to grow.”
Experts aren’t the only ones using 3D printers at Berkeley. Students in labs across campus, from Jacobs Hall to the Digital Fabrication Lab, can print models for their projects, quickly creating new prototypes. Even novices can now print their own projects at Moffitt Library’s Makerspace. For people new to 3D printing, says Panditi, about half of their projects fail.
“That’s what is great about 3D printing, and that’s also why there is so much trash generated,” says Panditi. “In rapid prototyping, you’re making iteration after iteration until you get it perfect. What happens with all those iterations is you throw them away. And that’s where all the plastic trash comes in.”
The most popular type of plastic for 3D printing on campus is bio-based PLA, or No. 7. (The plastic of choice used to be petroleum-based ABS plastic, which has since been found to release a carcinogen when it’s heated.) Although PLA is marketed as compostable, most facilities, including the facility that Berkeley uses - Republic Services West Contra Costa Landfill in Richmond - don’t use a long enough cycle to break down these plastics, which can take 90 to 120 days to completely decompose. After a normal 45-day cycle, the facility will sift through the compost material and pull out any plastics that remain, then throw them into a landfill.
The facility says it’s in the process of changing how long plastics stay in the compost cycle, so that eventually compostable plastics will break down, but hasn’t done so yet. That’s why it’s even more crucial to find alternative ways to recycle plastics on campus, says King.
Although No. 7 plastic can be recycled in the city of Berkeley and most cities in the San Francisco Bay Area, the campus chooses not to recycle it because there isn’t a U.S. market for it. That means it would be shipped to another country, such as China or Vietnam.

20min blender run. = Eco disaster
The BGM really hooked me up.
I opened it while in 1.75x and it's bumpin in here
Any idea how to make one of these (or a crude one at that) for cheaper and at home? Looks like a great idea but without thousands of dollars is it possible?
Maybe this can help you: preciousplastic.com/en/videos/build/extrusion.html
@@geebp7140 The link doesn't work anymore :/
Excuse me, can I get someone’s email that did this? Like Scott or Nicole? I have a really big idea and I need some help. Thanks!
Hey guys is it possible to make filament out of bottle caps?
daniel serrano yes it is. You will have a HDPE plastic filament
Definitely! ;-) There are also a lot of ABS bottle caps.
Yes sume guy in Australia plus others are collecting milk lids. Tubs of them. Its great. Ther trying to rase mony to by exstruders an. Print robotic 3d hand n limbs plus. I got a book on 3d printing recycling from few years back. Interesting stuff. It just taking of now in 2019// the more. Plastic. Bottal n top once we know we can melt down .is cool as. I'm shaw online info about what plastic product around today. We can. Yous.
Yes, it's but you need to wash and shred it then use extruder like mine: medium.com/endless-filament/make-filament-extruder-for-465-bbc0e8a74e74
Better use PET bottles. HDPE is very hard to print and doesn't stick to itself . You can use it for injection molding though.
That wasnt the Idea from them
The idea of implementing and crowdsourcing the program at UC Berkely would be their idea, and to go through all the hoops of organizing a program and get people to have the manpower to recycle the filament would be a lot of work. But the idea of recycling used 3d filament filament is not their idea and is clearly through the use of Filabots.
That is brilliant!
Lol the filament they show on the printer at the end is from matter hackers Not from that michene
How can you tell? This is about reusing plastic after all. They print something with the matter hackers filament, shred it, and turn it into a new filament on the same roll.
(I must admit that they probably didn't do that and just wanted to get the video out quickly, but it would be possible)
Why are you on youtube if the video is basically just text? I would love to know about zero waste printing. But as a dyslexic person i would prefer spoken videos.
Well I sure hope they don’t have a mix of filaments in there. Would certainly cause some issues...
how is the accurate is the diameter of the recycled filament / are there any other quality issues
and i guess this is for the environment only since the price for one of these recyclers is enormous and would need years even with 600lbs per year to pay itself off when considering that one spool of standard brand pla costs arround 25 - 40 usd per kilo
www.filabot.com/collections/filabot-core link to the recycler used
not including electricity, the grinder, the spooling mechanism and work hours spent
when prices on these machines drop id like to get one myself but for now this seems rather expensive
Well, we live on planet earth. This planet allows us to do things like 3D printing. We as humanity are putting a great stress on our planet. Microplastics are harmful to marine life, and it's likely also harmful to us. There are also plenty of other ways we're harming the planet. We're warming it up really quickly (The last time this happened was because of a super volcano, and it caused a mass extinction), we're destroying forests for short-term personal gain, we're fishing too many of certain species which puts a real stress on the ecosystems they're a part of, and ultimately also the whole ecosystem of the earth, which we're a part of.
Therefore, yes, it's rather expensive. But if you could afford it then it would bring the prices down which allows others to get these things as well which saves a whole lot of harm to our planet. I would be willing to invest in my future even if it doesn't directly show that I've made a change.
good work!
How can I get a heater like that
So...20 min of electricity at very high amps to recycle a half full blender. Well, that’s college for you.
Well, it does reduce what gets put into a landfill. That being said, that single setup they showed cost over $10,000. The lesson being that recycling is great...if you've got the dough to spend on it...
Amps cost nothing! Before you say anything you should study AC motor principles :)
@@bax442 Can you help me understand the math here, I'm confused by your comment.
@@scottf3274 Look up for ohms Law, and look at your electricity bill. You ll figure it out.
bax442 I don’t think you understand how the electrical utility works. Ohm’s law has very little to do with AC motor principles and amps do cost quite a bit.
What a great idea!
Cat Not theire idea
Wow
Sadly only corporations and universities can afford that kind of machinery but not the average person that have a 3D-Printer and does hobby printing.
We humans need to step it up more to recycle PLA printed objects that are considered wasted or damaged prints.
Many companies have claims that their PLA are biodegradable when they are actually not just to pass the government approvals.
Those companies dont actually tell the government that its only under certain specific narrow conditions that the PLA will be biodegradable. And yet they get to lie to the public
and say they are biodegradable and slap a huge sticker on their products saying so, when in fact they are not as many people have already proven many times over.
Yet the government & public seems to keep ignoring that part and Its one of the MAIN reasons why I am reluctant to purchase a 3D-Printer that I had my eye on for almost a year now.
Because I dont want to contribute to polluting the environment with plastics that wont fully biodegrade within a year or even within 3 years.
Not to mention as a native american, my elders would kill me if they found out im polluting the planet with plastics.
Wrong, 3-D printing is cheap, and it was cheap back then.
@@Ask-Jesus-for-the-Holy-Spirit
Wrong, 3-D printing is not cheap, and it was extremely expensive back then.
Zero waste = Berkley University being defunded by federal government 😁
How'd this go?
good
I would like to see more than only "Koumbaya" video.. so, I've put a "thumbs down".
I will be curious to see the size accuracy and printing properties Vs a cheap 12$/kg brand new spool.
Please, make a "Part two" video that show us the printed parts or send few rools to any RUclipsrs for proper review.
