Colin must be getting safety conscious, he tucked his tie in for the shredder test.

I found a low-cost version of a full automatic desktop injection machine. I guess this one is the one we go from (finally) : https://www.youtube.com/watch?v=M6UPpm4xlxw&fbclid=IwAR064vgVQB0CohrRsqRf8gXlIJd52rdsSVKyktqjgKR-tcdimL7IB7NBb84

from what i see :
– 2 Nema 34 steppers, around 200 Euro
– some metals, relative easy machined @ home for 100 – 200 Euro
– some electronics, around 100 – 200 Euro
– some links/belts, etc… around 100 – 200 Euro

Not sure we have to pre-heat hopper/feeder but lets see 🙂

Short satire about environment activists create smoke screens to distract you from getting wet. Whilst at it, let’s not forget George Carlin on ‘Saving the planet‘.

Another take on “saving the planet”, just by Jim Jefferies, hilarious.

So you’ve had it, gave up on the shredder…..but now you have all this rotating machinery…..what to do???

@s2019 not exactly, as much I’d like; We teamed up with a 3D print specialist; they told me there are now plenty of companies here in Catalonia and elsewhere who shred PET but don’t know what to do with that stuff; hence 100Kg of PET flakes are about 10 Euro just. However, they found a way printing it but before you have to grind it down to dust. We put now all resources to work out a v3 (hard to do since it jams even at 3-4 Kw, not to mention it’s not made for hard stuff ) / v4 compatible grinder addon (transmission is the biggest problem right now). But lets see this soon in another dedicated topic. I am still struggling to get our new football field size hall up and running; surrounded by metal and plastic specialists; for now I know there will be the printer, shredder and grinder package, pre-grinded PET packs as well for whose who want to go straight to print 🙂

Doing this kinda instruments as in your rhysonic video is pretty much what I’d love to see coming out of the PP community <3 (thats why I love you alu folie mold ‘trick’, it seems to open endless ways to build real useful machines from lego like buildup plastic), way to go !

I wonder if the path from flakes to dust could be done by going back to the high speed circular saw blades of death. That concept tends to generate dust whether you want it of not. The trick may be to design a feed mechanism (belt?) that provides a steady flat stream.

@s2019, a saw like that needs a pretty loud & fast motor and the whole thing is a pretty risky undertaking, at least making this as commercial device. conventional grinding is done by this kind of blades. Those blades rotate about 700 RPM, against a stationary blade. however, this can be a pretty cheap machine since single phase motor can be used (but with run & start capacitors) and in top those blades dont seem to wear out at all 🙂

Very cool. I remember long ago visiting a company that was making 3mm diameter turbines with EDM. Very impressive. If this becomes hobby priced it will be a big deal.

Just for fun https://www.youtube.com/watch?v=PN1ZJMFMGNs . I don’t know why @pporg keeps pushing these multi-KW motors.

Actually, I wonder if his approach for making the shredder blades can be scaled up to get a functional replacement for the elegant PP v3 blade shape.

@s2019, funny you, if you get a <1kw motor shred all day long PET and whatever the kids drop in there whilst making sure it’s still running good in 5 years with your new shredder box, please send me that thing 🙂
you may have forgotten to take off your shades today mate, lol

Yes, fun stuff.
Though you bring up an interesting question. We use shredding PET as a benchmark for the motors but is there anyone using (at the small scale) shredded PET for anything? Fortunately in our area there is a deposit on PET beverage bottles that helps keep them out of the trash but is there a good process for DYI recycling them? Your grind them to dust and 3D print approach has promise but is there anything else?

not that i know of, i know there are hundreds thousands new and subsidized companies sitting on that stuff; i hope we can progress on the topic as soon the new lab is ready. by having huge space now, i hope we can have all sorts of new experiments (extending my other meter long and dusty of ‘project nr. 201212xxx’ shelfs, lol).

pretty much a must subscribe channel; this one here is about the worlds best ever created machine, the lathe. in case you still don’t have one, please let me tell you, there is literally little to nothing you could do when it comes making plastic recycle machines. shredder, injection, extrusion and even molds to degree, all want you to have a LATHE 🙂
The first things I do to my students is letting them drill holes, from easy to difficult, after about 1-2 weeks full-time in the shop and only they fully sensed metal & forces as such, I send them for endless hours at the lathe for all sorts of different jobs and til now everybody started falling in love with this machine, and so will you.

Here’s a video of one of our best guys in the community, building a desktop injection molder, insane build but you get the idea.

Primitive Technologies, one of my top 5 favorite channels released a new video. Reminds me again of all the mental crap and ongoing cruelty and nonsense we accept, allow and even support widely isn’t actually any good for anything but reminding me what primitive apes we still are and probably be forever but also of  replacing this stressful and exhausting engineering career – fake life, fake buddies, fake success, fake team, fake coffee, fake culture, fake ffs fake everything – with something more natural like machine building whilst helping others was possibly the best change in my life 😉 greets to project kamp 🙂

Excellent channel ‘Applied Science‘, actually one of the best around; In particular a video about corrosion (shredder from mild steel).

please check also : science of roundness and flatness
