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.

[@loodwich]

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.

[@tdsangel]

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.

[@emilymarriott5927]

@@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.

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.

I wonder if putting the PLA pellets and coffee grounds into a blender before putting them in the filament machine would make a difference

[@hopefullyhigh]

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

[@lovecastle7154]

I bet if you ground up the first batch of filament and re-extruding it might help with the clumping

[@Muscleduck]

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.

[@Unmannedair]

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.

[@mellertid]

In addition to getting a twin-screw mixer and a ball mill... I would also suggest getting some lycopodium powder and some activated charcoal. The lycopodium powder should help repel water, and the activated charcoal could further improve compostability. I'd also suggest using a freezedrier to reduce the water content of the coffee grounds as much as possible.

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

[@chriswitty8552]

Hi Stefan, awesome video you did there. I work with extruders and the problem with your (usually with kneading elements in twin-screw extruders) to deagglomerate the coffee. Either you could extrude the printed filament again and hope for smaller particles or you would have to mill the coffee beforehand. If you mill it with the PLA, I would definitly use dry ice to reduce degradation of PLA. Also if you only feed powder to the extruder there could be problems with reduced feeding or no feeding at all. Hope this helps somewhat!

[@bazylinskuns]

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.

[@19rocket64]

Coffee has a number of fatty acids: including oleic acid. they are outstanding capping agents...which would reduce viscosity of the mix. not sure if this was the improved flow that you noticed when making it. But it may reduce layer adhesion as it is soluble in water. I use Oleic acid as a capping agent in producing nano particles and coffee or even better green tea are great sources. I wish I had that filament extruder for experimenting using my powdered nano material fillers.

[@IanSlothieRolfe]

It would be interesting to see if the properties improve if you are able to mill the coffee down to a finer particle size - it would certainly improve the clogging, and might even make it easier to make filament with a higher %ge of coffee. I like the look of the printed objects, I think it would be useful for printing wooden carving style objects, the brown is richer than any brown filament I have seen, it looks like polished mahogany somewhat. I am also interested in your experiments with composting, I have often been told that PLA biodegrades but have never seen any actual data or experiments on it.

[@jamesmihalcik1310]

Very impressive study. Interesting how much of the ground coffee actually makes it into the cup using a espresso extraction. The efficiency exceeded my first estimate. Being a coffee enthusiast myself, I would utilize a coffee filament as much as possible. Lightfast products would probably suffer Uv damage and appear fluffy with wear. You could finance your 3d printing by offering for purchase the large coffee bean and other coffee related products, I for one, would certainly purchase the large bean :)

I did my bachelor thesis about natural additives for bioplastics. Cacao powder worked as plasticizer and did better than coffee ground. The only problem you are going to have will be the cleaning. The cacao powder has a lot of oil and other stuff in it which will make a mess while extruding. Just give it a try though.

[@gentiligiuliano7882]

To increase mixing grade of coffe to PLA I would try a 2 stages approach. First mix 20 % Coffea. You should obtain a pretty bad filament, unprintable, but still a filament. Cut the filament in pellets similar size of virgin pla you have and than mix 50% the result with the virgin PLA. Similar size particles are more easy to mix than so different size, and separation due to vibration is more difficoult. Other approach is pre-mix the coffe with fine ground virgin PLA and than add this powder to the pellet virgin PLA. It should be an easier approach but I guess 2 stages one is more likely to give you better results

I bet the coloring would be more consistent if you brewed the used coffee grounds, mixed it with the PLA pellets and then dehydrated them.

Only using what could come out of a paper filter would mean much less clogging but much less texture too.

You could blend the pellets and fine coffee, maybe that would make it possible to use a higher amount of coffee because the shredded pellets would have more surface for the coffee to stick on :)
