Recycle 3D Prints and other Plastics at Home | Plastic Shredding | BB3D MK3 

You mentioned you wanted to use more recycle material and I’m glad you followed through. I would like see to the limits of 3 cubic INch volume, maybe different molds to show the drawback and where not to go when designing a piece

I have been looking for some good methods like this for a while! Thank you for your suggestion!

Ah yes finally a way of me getting hold of any plastic material in the UK lmao

That’s great. Now how do we convince you to design an simple diy extruder to make our own color mixes/filaments.

Amazing work, Ryan! It blends!

I wasted my money on a Blendtec blender to grind PLA, the plastic jar broke in about 15 minuted of use. If they made a glass jar instead of plastic it would have worked. I've tried 5 other blenders and all of them broke, either the blades broke off or the gears stripped. Haven't found one yet that is durable enough to grind PLA.

Can you make filament with this ?, I know about the pulltrusion versions , but want to find another way to make filment from ground up scrap prints and bottles that you can't normally cut .

Very informative... great video!

I see a very good modification potential with the blendtech blender, install that filter right under the blades, then you can have a hole underneat it and a collection tray. this way you tecnically dont need to be lifting it up all the time to pour, you get finished grinded plastic the size you need them to be from the getgo pouring out by themselves

Recycle plastic video? I think Ryan made this machine to get rid of that scooter motor, not to recycle plastic. Next we need a video on re-using scrap aluminum molds to make a Tesla. Great video Ryan!

While this is an interesting topic to me, this thing looks extremely dangerous as it is and I would not want to have a machine like this in my house. I have two little kids, who are very curious about all the things that I work with and if i built something like that, I would implement two safety features. I mean not only for others but also to prevent myself from doing something dumb: First, a lid, that prevents reaching into the machine when it's on and prevents it from turning on when open. And second, two operation switches with some distance between them, that need to be held with both hands to turn it on. I know this makes it harder to work with but I rather work harder, than have something bad happen to anyone.

One would think that if you put on safety goggles when using a closed blender you would put on chain guards for your drive but one would be wrong. May the little fingers stay safe!

Only one thing to say. CHAIN GUARD!!. Great video. Keep up the good work.

Great info, Ryan!!

Ive been thinking of recycling un reinforced garden hose. Ive got 100ft of the stuff, Its really flexible and has great pull strength. I have no clue what plastic it is though, its not rubber so...

Nice video as always! Is there any additional steps should I do before switching materials when injecting?

Hi Ryan. Did you experiment with HDPE or PP in the Blendtec? I've been using a credit card shredder for HDPE with similar results as yours. My machine is a little better at separating the chips, but like in your video, the pieces are larger than I would like them to be. Appreciate the time and effort you put into these videos.

how is that BLENDTEC blender holding up as a PLA SHREDDER... do you still recommend it as capable of doing the job of breaking down the PLA.

i printed in 100 % SOLID PLA... am i screwed in converting this 100 % pieces of PLA..... I need a melter... anything you reccommend ?.. can i convert it back into 1.75 size filament that is used in 3D printing ?

You don't worry about warping from not letting the plastic cool slowly in the mold?

The video is very good. I wonder how many grams of plastic can this machine melt? Can you help me?

When do you start a radio show with a smooth voice like that

You mentioned that the mold could be 3D printed. Could you provide more information about it?

Man this is so cool.

Did you do any other change to the wiring besides adding the potentiometer? What channels did you connect it to?.

But the real question is: will it blend?

do you have stl for hopper?

What about PET?

Good video, please put a belt guard on that thing your fingers are right there 🤕🫣

This is a great video! Would you be willing to share the 3D printer files for the chute and cover you built? I purchased the same shredder from DIY Chen and I’m currently getting it set up for regular safe use. Thanks!

What is the model name and number of the blendtech blender?

👍👍👍☝️☝️

I remelt my PLA in resin molds using a toaster oven. I make things like pendants, shot glasses and coasters.

Cool, looks like the perfect machine for the job, well maybe a cutting type tool rather than grinding would be better for softer plastics. Someone on youtube made a 3d printed shredder using the same type of design, and it surpsingly worked pretty good, to shred expired vegetables... but could easily shred plastic if you put some metal inserts on the teeth I was thinking, maybe even razor blades would be enough. I tried using a low powered blender and the fumes were surprisingly noxious off waterbottle caps and poor cuts due to softness put me off from going further, but this video inspired me to try again with a higher powered blender, and perhaps only with pla for now. Thanks.

It will blend ? :)

please print a chain cover in the cam view fingers so close. otherwise I love this

I wish grocery bags could be recycled into filament. It's some sort of HDPE.

how much mk3 injection machine? and where to buy it?

I am so jealous of you.. like, green eyes, worst of humanity, I'm a bad person, actually jealous of you. It's going to be a long time till I can build one of your machines but that's going to be a very happy day for me.

"non-descript fish hook"

No matter how much I recycle steppers alley h channels petg tubing heaters controllers etc.. I Will cost 200 in Australia just for a auger bit a the tube to house that as the extruder... It's so fkn expensive to build one even with half the parts 🤬🤬🤬

Time to become even more broke I guess...

Unfortunately, it is another of the many videos showing how to recycle filament while spending a huge amount of money. Another video that is useless. The final recycled product must always be cheaper than the purchased one. Otherwise it doesn't make any sense.

si pero el gasto en moldes es lo que para la compra de esta maquina
