I work in a plastic blow molding plant, I'd say to try starting off like you're blowing glass but as soon as you have the plastic on your pipe, close a mold around it So that it takes the shape of the mold better. You're working against time to get what you want and once you get the shape it needs to cool down quickly or it will warp
Oh god, you poor thing! I worked in several plastic manufacturing facilities doing injection press. It was a living hell. We did everything from polycarbs to acetyl, rubber and fiberglas. Terrible hot toxic work. I hope your workplaces has a decent EHS program, has ventilation and has some overhead cranes/walk behinds for loading your molds. *tips hat* You have my condolences. Be safe that shits NASTY!!!
It depends on how its formed. Your right, some used pressurized air, some used a rotating drum. ^ Andy is doing the fun O chem of polymers. Looks our friend up here and myaelf have done the BRUTUAL physical labor for production. Pft off on a tangent. Want a great paying job? Learn how to program the Fanuc PLC's once upon a time I programmed the Cinncy Milacron's and Van Dorn's. That will let you sone nice bank
Yup, there is a good chemistry between the two here, pardon me pun. Explanations were clear, everything about it worked to audiences benefit. Even the small screwups are great cause those do happen in real life.... You do drop a cap every now and then but the important stuff is done safely.
He finds trouble in carrying out an astonishing number of seemingly simple tasks. It's nothing short of a cosmic joke that he's somehow become the "How to Make Everything" guy.
so cool to see the show go from a dude just basically trying all on his own to make a sandwich, with no help, to a show where a dude tries it on his own, learns how its done now, and then goes back and re-applies modern knowledge to primitive resources. Its very cool to see the dichotomy between having general versus specific knowledge of something. But also I find having the experts on really helps make it feel like a full on show with an arc and with "segments" Keep up the great work!
I'd say he is first year gen chem that just wrapped up his O chem section. This is pretty basic stuff, it just sounds complicated to people who may not know too much about it.

@@okas425 Thats hard to explain. Its German. If you are interested you could type in the words Freizeit, Flug and Sphäre seperately into google translate. And let google pronounce it.😂 Then just say all the words in a row😃
As a kid we used have "Milk Buttons" or buttons made out of Milk protein on our clothes, they were very brittle but hey they were very cheap, and get a hundred for a buck.
That polymer is thicc! BTW i think the key to melting down and reforming your plastics is that there is not only a bottom form, but a top as well, matched (like stacked cups). Then put a spacer in between around the edges somewhere, and a weight on the top form. So you fill the hollow space between the two forms with plastic, then heat, it melts, top form compresses down and squishes the melted plastic around to fill the hollow space and top form continues to drop until the spacer forces it to stay off the bottom form by whatever thickness you ultimately want.
I love how everything you do is the natural process, and you even harvest those resources yourself. It truly is inspiring and is something that "how its made" doesn't show you.
Biodegradable alternatives are already available, they aren't in wide use because companies aren't forced to use them. They will save a dime anywhere they can. Until we change our laws to force companies to switch away from oil based plastics not much will change.
Such laws would only punish smaller companies that can't afford more expensive plastics, strengthening the hold of mega corporations on their marketplace dominance. Better to engineer cheaper bio degradable plastic in the long run.
I think we have to use less fuel to a point that by-product of fuel becomes scarce and using alternatives makes more economic sense. I don't think that day will come in the near future though.
Did you watch the video? He even addressed the popular misconception you are repeating. Biodegradable is not the opposite of oil based plastics. One is about the source of the plastic. That can be oil, or renewable. The other is how and when it degrades. That can be nondegradable, buliodegradable, compostable... This is an oversemplification for a youtube comment, but if u care look it up
Switching to biodegradable plastics isn't the answer. Reducing the amount of plastic we use as well recycling used plastic addresses the root cause of the problem rather than treating the symptoms (the impact of plastic waste on the environment).
18:12 Why not just sandwich the PLA with 2 muffin pans, to get the shape? Bonus points if you put on a layer of foil on the pans before sandwiching the PLA. It should protect your pans and you can probably just lift the foil and the end piece off with it.
My father remembers tar balls washing up on to Louisiana beaches in the 1940's. He thought they were from natural flows of crude in to the Gulf, but that may be apocryphal. It still would be an interesting source of petrol chemicals for your rubber.
I actually work for dart container and they use. Esentially plastic bits for foam cups. For the foam we use steam and a vacume to pull steam melted beads into a mold. For plastics we take a full long sheet that is heat to a pliable state before getting stamped with a ceramic mold or vacme sealed around it you might try this method
Polymer powder is mixed with a monomer liquid to make in-the-ear hearing aid shells. I added some red sand to the mix once and it looked like poop. As it sets up, it gets quite pliable like clay and I made handles for some Exacto blades used in opening hearing aid shells for repair. Silicon molds are used to form the shells.

It's absolutely crazy how we've known of these methods for years, but they're not used in the mainstream market. I think it's time to start using these methods, instead of just showing them on tv.
Maybe this video would help calm down some of the new age health hippies - no, your food is not made out of plastics, your plastics are made out of food!
What an excellent display and explanation of basic polymer chemistry from the University of Minnesota (can we have that guy back again?). Well explained and nicely put into the context of your project by your good self.
I'd be more apt to being exposed to that as opposed to the benzene, uric acid and aldehyde plastics. You want something wicked NASTY? Acetyl heated to 375F with Polypropylene, that will bring you to your knees. Had a release of that mix at one of my workplace. Facility was three football fields long. K, about 10 grams of the acetyl mixed with Polypropylene I was heating. I had all I could do to get under the cloud, hit my E stop and run like hell. Smoke knocked out 2/3's of the plant. We had to evac to out underground evacuation zones. Scary af
Lol Every time I watch your videos, all I can think of is "Does this guy ever plan and think about the plan before he does it?" Fun to watch tho, so much grace on the handling of all the chemicals.
Maybe you can try making a cup the same you would with paper for example If you make big flat pieces and cut a circle and a rectangle out of them You can make a cylinder out of the rectangle and "weld" the seam And cut a circle the right size and weld it to close the bottom of it
Do you remember when you were asking yourself in the school WHERE EXACTLY are you gonna use some type of math process in real life? I do. Yet here I am watching a video which I'll never use and probably forget after few hours, but I still wanna watch more of it ...
You could make a cup by melting the plastics into a beaker and using a slightly smaller cup as a press into the liquid plastics then put something heavy ontop to hold the central cup in place until it dries
@@Lunch_box "Theoretically" Have you ever owned a 3D printer and used it extensively? They're not even the slightest bit forgiving when it comes to filament. They rely on very clean, very CONSISTENT plastic. You can't just shove any stringified plastic and expect it to work.
They have machines you can use at home to do it for you (make PLA beads/shards/powder into PLA filament), not very expensive anymore either for smaller ones. I don't think he's planning on trying to do it manually, just making the plastic manually. @@Lunch_box
(Sorry for this joke beforehand. I actually love your science videos..) And here I thought Polymerization was when you combined two or more monsters together. =D
PLA gets soft enough to work with at a low enough temperature that you could try submerging a disk in boiling water then quickly forming it after removing it from the water.
Plastic acually refers to the way the material deforms. The opposite of plastic is elastic, so a plastic deformation is when you deform something, and it doesn't return to its original shape. And since that's the most common household plastic we encounter, plastic has become the household name for polymer.
for the plastic molding you should look into vacuum forming, i think there's a video on it with Adam Savage. basically you'd try to melt the plastic into a sheet, then mount that sheet in a frame above a box with the mold in it. this box gets depressurized (with a household vacuum) and you heat the plastic, so it becomes soft and gets pulled inward onto the mold, creating a sort of envelope above it. Might work better than your attempts at what is basically injection molding, but I dunno
A quick tip. you actually melted the PLA at the end, you just want to make it solf, which comes only at about 90 degress., cause you can see it melted like wax, you want it to be like a hot film. Idk if this helps lol, but yeah. About 85 through 95 degrees is the temp at which you 3d print with pla.
People have to start realizing that even with the long degradation duration, synthetic plastics are still better for the environment than paper. Paper requires much more resource to create. You have to chop down trees, plant paper trees (these trees destroy habitats for flora and fauna), transport the trees, process the wood, create the paper, etc. The ecological impacts of making paper are awful. You can only recycle paper so many times before it becomes a useless pulp. Plastics take very little resource to make and were created to save the trees. Styrofoam takes even less resource to make. You can reuse plastics many more times and upcycle them into benches, mats, furniture and etc. I hear enzymes have been discovered to degrade the plastics into carbon and other constituents. It's because they last a long time is why they make such a good choice. For instance, reuse plastic bags rather than paper or "reusable" bags. You have to go grocery shopping every day to even come close to making up for the environmental impact of most reusable bags. Stop listening to what the news outlets say and just do a little digging of your own. You will be surprised by your findings. I love the concept of bioplastics, using plant parts that would otherwise be thrown away to make useful things. Avocado pits can be used to make a plastic. Avo pits are typically tossed away anyways, so why not put then to good use. However I'm sure there are some drawbacks.
if you're just trying to shape PLA, you can bring it up to its glass transition temperature and it doesn't get sticky to stuff other than itself, just soft.
I work for a company that makes plastic molds and plastic medical parts. There's A LOT that goes into making professional level plastic materials. Next time you should look into injection molding :P
You need injection molding to make something with a plastic, coat the molding try in petroleum jelly or even olive oil then melt the plastic, and at the same time either vibrate the liquid plastic or you can just keep it at a high temperature for a while while the bubbles escape. connect the mold together then force hot liquid plastic into the mold. You can use a metal injector. (Make sure you draw a solvent into the injector so you dont ruin it) Wait till it hardens and melt the injection lines off the finished project.
You should consider buiding a twin-screw extruder compounding machine, take this kind of PLA fibre and mix it with additives including pigments inside the machine and thus get some cool masterbatch with the exact properties and color you want, then use a DIY filament maker (like the one made by ArtMe 3D) and turn it into 3D print filament!
When he went to the lab and they started planning this process on the molecular level, I became squeamish that they might just end up chemically recreating the same polymers derived from petrol-based plastics. Oil is after all the result of biomass breaking down under certain conditions. We want to be certain that our replacement of petrol-based plastics breaks down and truly bio-degrades before it becomes a problem in the ecosystem.
There are people with 3D printers that produce prints directly from pellets, rather than filament. That is mostly done for **very** large printers, the sort of thing that can print a chair or a full sized model of a person. SeeMeCNC have one and from videos I've seen them in, they seem to be nice guys...might be worth reaching out to them if you end up doing that sort of thing.
I tried to make my own drink when I was 9 or 10 so I decided to put lemon juice in milk, boy was I surprised whenever I found clumps of disgusting shit floating in a clear liquid. Realized later that I made an early form of cheese.
We are missing acknowledgements to the students who helped with the PLA synthesis and the research group they belong to. Check out U. of Akron, Case Western, U. Southern Mississippi, and U Mass Amherst for help with synthesizing and processing polymers.

So cool! I 3D print with PLA all the time and it’s really cool to see where it all comes from
15:28, "Polymer smoke... Don't breath that..."
I'd be more apt to being exposed to that as opposed to the benzene, uric acid and aldehyde plastics. You want something wicked NASTY? Acetyl heated to 375F with Polypropylene, that will bring you to your knees. Had a release of that mix at one of my workplace. Facility was three football fields long. K, about 10 grams of the acetyl mixed with Polypropylene I was heating. I had all I could do to get under the cloud, hit my E stop and run like hell. Smoke knocked out 2/3's of the plant. We had to evac to out underground evacuation zones. Scary af
I get that reference.
@@steller7515Microwave show?
@@steller7515 Come to think of it, will it blend guy said that too.
Its amazing how he made all that expensive lab equipment from scratch... very impressive
Ultron is right;
"A very versatile material, and they used it to make a frisbee"
Almost 1 million, congrats dude!
Lol Every time I watch your videos, all I can think of is "Does this guy ever plan and think about the plan before he does it?" Fun to watch tho, so much grace on the handling of all the chemicals.
Maybe you can try making a cup the same you would with paper for example
If you make big flat pieces and cut a circle and a rectangle out of them
You can make a cylinder out of the rectangle and "weld" the seam
And cut a circle the right size and weld it to close the bottom of it
I love the life-size clue knife on your wall
I love the amount of effort you and your team put into your videos. Keep up the great work
Do you remember when you were asking yourself in the school WHERE EXACTLY are you gonna use some type of math process in real life?
I do.
Yet here I am watching a video which I'll never use and probably forget after few hours, but I still wanna watch more of it ...
You could make a cup by melting the plastics into a beaker and using a slightly smaller cup as a press into the liquid plastics then put something heavy ontop to hold the central cup in place until it dries
Just Wow. Can't wait for you to tackle electronics!
Oh buddy, getting your DIY PLA to work as 3D printing filament is gonna be an even bigger nightmare than trying to mould it, fair warning.
@@Lunch_box "Theoretically" Have you ever owned a 3D printer and used it extensively? They're not even the slightest bit forgiving when it comes to filament. They rely on very clean, very CONSISTENT plastic. You can't just shove any stringified plastic and expect it to work.
They have machines you can use at home to do it for you (make PLA beads/shards/powder into PLA filament), not very expensive anymore either for smaller ones. I don't think he's planning on trying to do it manually, just making the plastic manually. @@Lunch_box
(Sorry for this joke beforehand. I actually love your science videos..)
And here I thought Polymerization was when you combined two or more monsters together. =D

PLA gets soft enough to work with at a low enough temperature that you could try submerging a disk in boiling water then quickly forming it after removing it from the water.
Shoutout for the blendtech blender.
Don't breath this.
The Ballymer looks like cotton candy!
Plastic acually refers to the way the material deforms. The opposite of plastic is elastic, so a plastic deformation is when you deform something, and it doesn't return to its original shape. And since that's the most common household plastic we encounter, plastic has become the household name for polymer.
Congrats on 1M subscribers!
Channeling Nile Red like crazy... I love it!
This channel wishes.
Maybe if it was only the guy who did the real work, not the real channel host.
Congratulations on 1 Million Subscribers!!!!
for the plastic molding you should look into vacuum forming, i think there's a video on it with Adam Savage. basically you'd try to melt the plastic into a sheet, then mount that sheet in a frame above a box with the mold in it. this box gets depressurized (with a household vacuum) and you heat the plastic, so it becomes soft and gets pulled inward onto the mold, creating a sort of envelope above it. Might work better than your attempts at what is basically injection molding, but I dunno
A quick tip. you actually melted the PLA at the end, you just want to make it solf, which comes only at about 90 degress., cause you can see it melted like wax, you want it to be like a hot film. Idk if this helps lol, but yeah. About 85 through 95 degrees is the temp at which you 3d print with pla.
You should make a jelly bean
Planning on it!
Good
And boom he did!
People have to start realizing that even with the long degradation duration, synthetic plastics are still better for the environment than paper.
Paper requires much more resource to create. You have to chop down trees, plant paper trees (these trees destroy habitats for flora and fauna), transport the trees, process the wood, create the paper, etc.
The ecological impacts of making paper are awful. You can only recycle paper so many times before it becomes a useless pulp.
Plastics take very little resource to make and were created to save the trees. Styrofoam takes even less resource to make.
You can reuse plastics many more times and upcycle them into benches, mats, furniture and etc.
I hear enzymes have been discovered to degrade the plastics into carbon and other constituents.
It's because they last a long time is why they make such a good choice.
For instance, reuse plastic bags rather than paper or "reusable" bags. You have to go grocery shopping every day to even come close to making up for the environmental impact of most reusable bags.
Stop listening to what the news outlets say and just do a little digging of your own.
You will be surprised by your findings.
I love the concept of bioplastics, using plant parts that would otherwise be thrown away to make useful things. Avocado pits can be used to make a plastic. Avo pits are typically tossed away anyways, so why not put then to good use. However I'm sure there are some drawbacks.
Exactly! It's nice to see someone that understands the drawbacks of those sorts of things :)
if you're just trying to shape PLA, you can bring it up to its glass transition temperature and it doesn't get sticky to stuff other than itself, just soft.
I love that Blender of Science
I work for a company that makes plastic molds and plastic medical parts. There's A LOT that goes into making professional level plastic materials. Next time you should look into injection molding :P
You need injection molding to make something with a plastic, coat the molding try in petroleum jelly or even olive oil then melt the plastic, and at the same time either vibrate the liquid plastic or you can just keep it at a high temperature for a while while the bubbles escape.
connect the mold together then force hot liquid plastic into the mold. You can use a metal injector. (Make sure you draw a solvent into the injector so you dont ruin it)
Wait till it hardens and melt the injection lines off the finished project.
This video reminds me why I study Biotech. Really get to see the actual process.
13:52 the pun made me laugh way more than it should
You should consider buiding a twin-screw extruder compounding machine, take this kind of PLA fibre and mix it with additives including pigments inside the machine and thus get some cool masterbatch with the exact properties and color you want, then use a DIY filament maker (like the one made by ArtMe 3D) and turn it into 3D print filament!
The science dude needs to be on TH-cam
Rip. Those scenes in the lab made me realize how much organic chemistry I’ve forgotten
TheWizardOfOsborne you can always relearn it
Make hemacite!! It's an old plastic made by combining blood and sawdust under extreme pressures that used to be extremely common
Lab: "...is funded by the National Science Foundation-"
Me, automatically: "And Viewers Like You!"
When he went to the lab and they started planning this process on the molecular level, I became squeamish that they might just end up chemically recreating the same polymers derived from petrol-based plastics. Oil is after all the result of biomass breaking down under certain conditions. We want to be certain that our replacement of petrol-based plastics breaks down and truly bio-degrades before it becomes a problem in the ecosystem.
Perfect... just in time for my thesis.
Awesome video, Andy! I love your thorough approach!
You can get a filament extruder (for 3d printers) online, so you should have done that, and 3d-printed a cup.
There are people with 3D printers that produce prints directly from pellets, rather than filament. That is mostly done for **very** large printers, the sort of thing that can print a chair or a full sized model of a person. SeeMeCNC have one and from videos I've seen them in, they seem to be nice guys...might be worth reaching out to them if you end up doing that sort of thing.
Nice to see yall are fans of Glass Animals at 14:14
Edit: congrats on 1 Mil!
Ah, writing on the fumehood glass with a permanent marker... I do this every day!
that guy a 9:00 taught me more about science in that little minute than my science teacher at my hs 💀
14:12 Looks awesome !
Hats off to you for failing at everything and still uploading it xD
I feel like this channel is the “technology tab” from the game “civilizations” 🙂
Very cool! It would be quite interesting to try making 3D printer filament from it.
I didn’t even understand most of this but Ik I loved it
Idea for some point in 2019. Would love to see you go through the steps/process in manufacturing a personal chassis for a desktop computer.
I tried to make my own drink when I was 9 or 10 so I decided to put lemon juice in milk, boy was I surprised whenever I found clumps of disgusting shit floating in a clear liquid. Realized later that I made an early form of cheese.
We are missing acknowledgements to the students who helped with the PLA synthesis and the research group they belong to. Check out U. of Akron, Case Western, U. Southern Mississippi, and U Mass Amherst for help with synthesizing and processing polymers.
Almost 1 mill dude! Congrats! :)
