I made my own Bio-Composite material for 3D printing by mixing Spent Coffee Grounds with PLA. We’ll talk about why such a material might be useful, what I had to do to make it printable on a regular 3D printer, how the mechanical properties are, and most importantly, how it smells during printing.

Drink coffee or print coffee - On which side are you?
Don't forget to like & subscribe and share this video on Facebook, Reddit, Twitter, and other platforms!
I hoped a little bit that you bought it so I can buy it too because it's very cool!
I brew a lot of coffee, and I could say that you could do a similar test with light roast coffee.
The difference in between light and dark roasted coffee is the brittleness. Dark roasted coffee are less dense and brittle than light roasted coffee. So, you should get a better result with a light roasted specialty coffee.
You forgot an important additive for polymers "Blowing agent" to make a cellular plastic instead of a bulky one, whit that you could reduce the density of your printings.
print coffee :)
Besides saving material the filllers modify the mechanical properties quite much. In a thoothfilling the Composite has round up to 94 Mass % of fillers in the material.
Fillers reduce the durability of a material - the cracks run just around the particles and the failure happens earlier and with lower forces.
The trick to improve the strength of a material through fillers is to chemically bind them to the base material - e.g. the mentioned partical in dentistry are bound to the Bowen-polymers with silan molecules.
I have no idea what the residue of old brewed coffee beens contain chemically but you'll find out. There will be a possibility to adapt the hydrophilic properties and the chemical bonding.
The best thing will be to have premixed coffeebeannanoclusters to mix to the pla.
But in the end it's not about the mechanical properties but the smell.
Finally, actual cnc kitchen
Cnc Cafe..but close enough
Xd
Lmao
3D printer cafe
lol nice
PLEASE send a sample to James Hoffmann, a coffee youtuber that recently made a 3D-Printing video.
Looking forward to your backyard composting experiment!
Always fun seeing these two worlds collide of one great creator that follows another
Yeah, me too. Since I've never seen any real degradation in PLA even outside I'm quite exited if the compost environment will change anything.
@@CNCKitchen Good luck. From my understanding, your compost pile will need to maintain an internal temperature of 130F (about 54C) to actually compost PLA, which is a tough temperature to consistently hit in a home compost situation. I hope you find a way to compost PLA that can be done at home reliably. That would be a game changer with all the scrap 3d printing produces.
@@CNCKitchen Looking forward to see the results, though I am not overly optimistic that PLA can be easy composted at home. But, who knows, you will let us know in another nice video :)
Damn, you beat me to it. Only read this after posting basically same thing...
James Hoffman: Let's 3D print coffee accessories
Stefan: Gotcha, let's print with coffee
The timing couldnt have been any better, within a week of each others video.
meanwhile i just watched a fusion 360 tutorial where a guy made a coffee maker, and i'm drinking coffee right now
James Hoffman, not Jeff lol
@@lovecastle7154 didn't even notice it, thnx
@@hoffer_moment that's a really great tutorial, the one with the mokka pot. Did you print the parts?
@@0oSiLveRo0 it was very hard to follow without a prior fundamental in depth tour of the program, so im starting there first. coming from sketchup it's a doozy, but sketchup is just so bad for making changes to complex parts of a model down the line
Pretty interesting project, I love the 3D Printed Coffee Bean! 😌
Great model, yes!
The paper bag was cool!
I live in a rice growing region in Japan and I'd love to make a rice husk blended filament.
You mean organic PVA? :D
Those coffee particles still look huge to me. I work with twin screw extruders so maybe I'm just used to super fine pigments, but we have never had a noticeable drop mechanical properties even at 5% pigments. Maybe try putting the bowl and coffee grind in a freezer for a while right before grinding. ABS/ASA is commonly cryo grinded because it will just remelt from shear otherwise. Making it colder and more brittle may help get smaller particles and better mixing.
You're right about that. I'm currently looking into ways to grind the material down even more.
@@CNCKitchen Do you have space for a ball mill in your freezer?
@@CNCKitchen team up with James Hoffmann, he knows a thing or two about grinders
3d Fuel sells a "Wound Up" brand of coffee Filament, I used some a few years ago, it's pretty cool! They make a Buzzed brand that uses beer hops and another that uses hemp fibers.
I love how you can do this yourself now! This makes the machine worth it! I drink soooooo much coffee lol
Yeah, I've seen that! Need to ask one of our local brewing companies if they can spare some waste.
@@CNCKitchen ooooooh I love the idea!
As a consumer, specialty filaments are typically too expensive. As a maker, I'd like to experiment myself! As a citizen, I think sustainable options should indeed be pursued.
yeah honestly if I had the machines to make my own filaments I'd be all over that. Especially if it could be made foodsafe, imagine those compostable utensils but if they were backyard compostable!
This is so great, you are truly living up to the name of CNC Kitchen!
James Hoffman: lets not put coffee in everything!
Stephan: Ok?
I wonder if putting the PLA pellets and coffee grounds into a blender before putting them in the filament machine would make a difference
yeah mentions something like that at one point where he says he mixed the grounds with the broken up pla balls to help evenly mix it, or something like that haha
I bet if you ground up the first batch of filament and re-extruding it might help with the clumping
For the higher coffee content, it might be an idea to mix the coffee and PLA into a fine powder and extrude them as pellets first, then use those pellets to extrude again to make the filament.
The plastic fluidity changes because your filler changed the specific heat of the plastic. Your thermal cartridge is putting out a certain amount of power per second and your plastic is absorbing that same amount of power. Adding your filler means that a certain volume of plastic can actually hold less heat now and therefore reaches a higher temperature for that amount of power absorbed.
"The most favorite kitchen tool of Germans"
Not just for Germans, I'd say for the whole of Europe
I don't like the Thermomix. It's typical for an All-in-One-Machine. They can a lot, but nothing very good. So at the end, you still have more than this one machine in your kitchen. And for 1000€ I get a lot of mixers.
Thermomix, never heard of it nor ever seen one in NL. So I highly doubt your claim.
@@rolfkreuzer4466 That's true, I don't have one, they're really expensive. But the people that can afford them do get one and frequenly use it.
aka Bimby
I like how thorough this is and all the effort you go through with making sure its properly dry and fine and then checking the different percentages :D I look forward to any updates too! That first vase you printed looked SO PRETTY! I think I would like the filament just for how pretty it looks :o
Stefan is having too much fun with his 3devo
I would too if I could afford one. haha
Doing my best as long as I have it!
"I'd be really interested to know how the properties further degrade with higher coffee contents" That line set me giggling for an embarrassingly long time. Well done on this project and I would also be interested to know!
Wow, great video! I'm regularly impressed with the thoroughness of your experiments. Really cool stuff!
That is simply brilliant. And the colour is absolutely fantastic! Great job Stefan 👍
welp now you can make a coffee cup out of coffee
i love your channel btw
Should've, yeah. Thanks for the kind words!
@@CNCKitchen np
i have started to almost exclusivly use polyterra for my pla parts. Not only does it give and amazing finish and prints very well, it also uses 20% organic fillers and comes on a really well made cardbord spool
That stuff is pretty amazing. I used to to print some coasters that look like toast and waffles. The banana yellow is spot on Eggo color, haha!
It's definitely not as strong, but the matte finish is beautiful. My biggest problem with it is the smell while it prints. Gives be an awful headache. 😢
The only bad thing about Polyterra is the bad layer adhesion. I love the matte finish.
@@Felipeh999 i havent had issues with that yet. I print it at 205 regularly and 200 in my mmu
@@oOSpecialProskillsOo Ok, to be fair, layer adhesion is not bad, it's just not as good as regular PLA. Normally I don't have any problems with it, but I've had small details breaking off very easily and layer pealing apart in vases.
This filament would be great for little figurines to absorb room odor since coffee grounds neutralise odors
Probably the first time I've seen someone make real coffee as an intro. Milk frothing is no joke but coffee was probably still good :)
Most strange thing is to see a German or Austrian make REAL espresso
No instant coffee at our house. Even though fully automated coffee machines are quite widespread in Germany, I prefer the honest, manual way.
@@CNCKitchen yeah
Dang the video has begun and I thought I was watching a third ad! And it was more charming than the actual two I just watched, there's to say!
I actually wasn't aware of the blog. I appreciate that you're going the extra mile
Finally CNC kitchen is in the kitchen
🍽
I love that you pursue your curiosness
I waited until this morning to watch this video for the obvious reason xD Awesome video! No diamonds without pressure ;)
Thanks man, enjoy your Sunday coffee!
Brilliant video as always, dude! You're really informative and creative!! Love your channel😍
This is so much work I appreciate your effort.subscribed.
Thanks for the sub!
That is a GORGEOUS filament.
haha, cooles video! Bin erst neu im 3D-Druck Thema mit meinem ersten 3D Drucker und bin vor kurzem auf deine Videos gestoßen. Echt nice Videos!
I'd be interested in trying some like this for my 3d printed model building tools. Tools like anything wear out or break, and I'd feel a lot better knowing that the material were more ecologically sound.
Still one of the best 3DPrinting Content creators on here. Keep it up, Stefan - great Work!
Thanks! ☺
3D printing and coffee, my two favorite things :D
This is so cool! I love your videos!
Glad you like them!
Ich hab mich schon immer gefragt wie schnell sich das abbaut, du hast echt n gutes Gespür für die Themen.
I´ll always asked myself how fast it dissolves, you really got a good sense for topics.
Grüße
greetings
:)
Such a cool video! And just as professionally created as all your work 👍
I just come around this channel a few days ago, mr3dprint shows how he produces his PET filament from plastic bottles with really little material, no leadscrew, no overly expensive extruder, just a razor blade, a heater block, a stepper and a 3d printer main board for the temperature regulation
Finally. After all these years, we have Kitchen CNC
geniale Idee und Umsetzung. Danke!!!
The Thermomix! My top rated machine throughout the house. It is honestly my Family's favorite kitchen appliance. Love the combination of coffee and filament!
I did a school scisnce project on what can help keep snails out of a garden, and I found that used coffee grounds can be used and out of the 4 things I tested it had the best result at nearly 100% success rate. So if you dont want to make filament, you can try putting it in a pot or around a garden!
The paper bag vase looks awesome with the coffee PLA!
This seriously seems like it was perfectly timed with James Hoffman's recent video about 3D printing coffee gadgets... He even recently had a video about how people need to stop putting coffee in every product. Your intro is even somewhat Hoffman-esque.
Bravo! Love this video and love coffee! thank you sir
7:50, I'm glad you mentioned a ball mill. I've seen so many youtubers lately that don't know the proper way to grind powder that just use a blender and then shrug when it doesn't work.
If we're talking about bio-composite polymers, using chitin can be a great experiment. Chitin is what crab/lobster shells are made of and has some amazing material properties. Chitin or it's more workable counterpart chitosan can be bought in bulk easily and cheaply.
When I started watching this channel years ago, I wondered why ktichen was a part of this. Now I understand.
Fun and interesting. Thanks for sharing!
I'll never forgive youtube algorithm for making me miss this video for FULL DAY without me getting notification :(
Interesting, fun and entertaining ! Thanks! 😊
Love projects like this
dude! this is awesome! 😂
very good stuff as always!
Smell, texture and color would definitely get me to buy this for the same reason I buy wood filament. Having more options for decorative pieces is always great.
I love the way that the spent coffee grounds look like little brownies
I would definitely buy this coffee filament, really pretty! and great thinking!
Wasn’t exactly expecting this…
…but I love it!
i would definitely buy one or two spools of coffee pla from you. i love the colour and the effect in thin walled prints.
CNC Kitchen + Coffee= best Crossover ever
Owesome idea using coffee! I would definitely buy such a filament because I love coffee!
Maybe you could try it with fresh coffee ground. But the oils might be a problem.
No problem, no oil if you buy the cheap brands from some of the big franchise supermarkets
Great video! Your composting experiment sounds really interesting! I'm always wondering how much biodegradable PLA really is. It will be awesome to see how it compares with your coffee filament.
@CNC Kitchen: you need to make tests on ASA vs PLA vs PETG vs ABS on "weather resistance": Water (normal & salty) exposure, UV Light, Heat of the sun.
That would be so interesting to see how the element affect 3D Prints :)
This is a great way to wake up while working!
That was exactly the answer I was looking for about a question I never asked.
You can also use spent coffee grounds as a rub for things like steak, just mix it with salt in the ratio you'd like. Or even mix it with chocolate when making cakes, pies, cookies, chocolate milk, etc.
Looking forward to your composting-video.
Would buy coffee-PLA ... looks fantastic!
When i subscribed to this channel, didn't thought it would actually have anything to do with the kitchen. color me surprised😂😂😂
Very nice project !
Great vid! Would be fun to have one of 3DEVO's machines!
11:38 I'm watching this instead of working in my homework for tomorrow
havent seen the video. Already love it
☺
Coffee filament, ... now i've seen it all.
Love your work
it's a nice colour
that's for sure
You are a mad man, I love it!
Man! I don't know about any thing else, but the color is amazing!! It's so cool and coffee like that I'm willing to buy some!
I must admit, I was expecting you to tell us that you found a way to polymerise coffee beans into PLA
Unfortunately not😉
Well, you could try polymerising Cappuccino. Or at least extract the lactic acid from Cappuccino and use this😂
And now I need a cofee ! Awesome video !
Enjoy it!
PLA doesnt decompose in conditions found in nature. Unless you have an industrial composter, waste of time.
The coffee will be long gone but the plastic will remain in the environment.
Its not like the PLA decides to change it properties because a filler. Its just volume
an idea for mixing is adding by 5% increments, extrude 5% grind the filament, add extra 5%, extrude another time etc etc
I can't tell whether I'm watching James Hoffman or CNC Kitchen, and I like it!
Very cool!! I would buy for all the reasons you gave :-)
Looking forward to the Prusament PC Blend CF review as well Stefan, I hope it's in the making :D
Cool experiment. I can't imagine all the fillers peeps would try once home-extruding fresh filament gets cheaper.
I'd love to get my hands on that filament :)
Smooth segue for presenting an advertisement. Good work. Interesting to see the properties of mixing PLA with our loved beverage. I guess we should look into making coffee grind stronger, would be nice to reach 100kg of tensile strength.
Very cool. This was I thought about my coffee ground at my home 😆
My favourite coffee channel James Hoffmann has just got into 3D printing, I hope he see this.
Ich habe letztens eine Rolle ABS in einer Tüte gelagert, in welcher wir zuvor Senseo Pads gelagert haben. Habe mich gefragt warum mein Drucker plötzlich nach Kaffee duftet, bis mir aufgefallen ist was passiert ist. Aber das hier ist natürlich next Level xD
That coffee bean printed from spent coffee beans looked like a real large coffee bean.. 😍
Echt interessanter Channel mit coolen Experimenten xD
Me: Needs Caffeine
Also Me: *Sees My recently printed picture made from Coffee Beans*
Also Me: *N O M*
when you said "I enjoy printing and coffee", I thought you were going to print a cup or something. Far exceeded my expectations
Watching this while my coffee is brewing 😋
Coffee grounds after dried are quite a good dessicant so after drying it could still retain some moisture after sifting and such
I'd try a filament similar to this for all of the reasons that you mentioned
Devo is really trying to get in there sending these filament makers to every RUclipsr
Very good experiment anyway. Nice job
nice color 👍
