Damn man, this is by far the most simplistic and CLEAN method I have seen! And the fact that you share the build list is an added bonus. Thank you!! How long did it take you to develop and test this out? It is wonderful

[@tonycstech]

Yep and also its not working. The diameter is all over.

[@dtrotteryt]

@@tonycstech Well, its a great beginning IMO. I do hope you keep at it. It has inspired me to look into trying something similar with my spare parts!

[@function3D]

@@tonycstech The diameter depends on you, how consistently you are able to cut the PET strip, ultimately how patient you are to develop the skill to handle the PET bottle cutter, the machine only does the hard work but does not solve the inaccuracies in cutting

[@KarSahakyan]

Cut the bottles twice as thin, take two different colors and combine them into one philoment, half will be of one color, half of the other.

[@violettracey]

Awesome idea!

[@JeffDM]

Is there a reason why you're manually puling and winding the ribbon? PETpull winds the ribbon to a spool. PetBot makes filament right off the bottle strip without the extra winding step.

[@st0rmforce]

My guess is that it's simpler and doesn't require a lot of extra effort. Having the ribbon wound onto a reel means that the extruder doesn't have any resistance to work against. Grabbing and pulling is the easiest way to cut the ribbon.

[@ArthurKiyanovski]

I wonder if this can be made into an automatic process. Throw in a bottle. The machine heats it and pushes out the thin plastic thread. This manual process is a bit too much work to become popular

[@cora2887]

It definitely can be and is automoted, thats usually in factories though. This is just kinda the consumer way of doing it. In factories they just throw all the plastic in a big shreader and melt the chips

[@Arbiter1223]

I've seen variants of this that have it where it cuts the bottle as it's already being pulled through the pullstruder, so that's one step that can be automated. I've also seen a video mentioning someone actually built the pullstruder into a 3D printer so that he just needed to feed the strips to the printer, and it would fold the filament and immediately print it. The main thing left to automate would be prepping the bottle for cutting, including heat forming the bottle to be as flat-surfaced as possible, as well as cleaning both the inside and outside. This might be better-suited for manual work, but overall this is still a solid proof of concept I think.

[@outkast187]

You would use a grinder. Its cost prohibitive to do any other way. And you gotta do massive amounts. All the work this guy did would not net a profit. If he did 30 of those bottles it would produce maybe $10.

[@jannejohansson3383]

You could press that plastic bottle to printing core with chamber, mechanical force and nozzle that leads ready hot core to waterpath, and finally some collecting cylinder that spins slow. Then there's not waste left from bottle.

[@Robin_Goodfellow]

Absolutely the cleanest extrusion setup I've ever seen. I tried doing it once, it was a mess.

[@shaggybg]

Amazing. Well done and kudos for reusing the bottle like this. :)

[@Kest430]

How much filament is produced from one bottle? How long does it take to recycle one bottle? Given the preparation time (remove the label, wash the bottle, dry)

[@Arbiter1223]

Hello! I've been researching this and similar projects for a few months now, and I must say this is most impressive! I am putting together my own pullstruder using a hot glue gun heated to 200-220°C for the extruder part and should be ready to test it soon, hopefully! I did have a tiny question regarding the strip guide, though. What do you use as the cleaner inside the guide? From what I can see, it appears to be a bit of sponge, yet if so, I'm not sure if it should be wet or dry. Could you clarify this, please? Again, very impressive work! Your videos have been very helpful in my journey to make my own pullstruder device! Thank you. :)

[@PaintballPlanet]

Great job, have you thought about mixing colors? Two narrow PET strips in different colors treated to obtain a two-color filament !?

[@ulforcemegamon3094]

You can change the color of PET filament simply by putting some Marker in it , if the PET bottle is transparent, then you can use a red Marker and write the PET bottle and that should change the color of it

[@lukaszslowakiewicz9395]

So much effort for so small result. Works as a proof of concept.

brilliant way to reuse, nice setup

[@RickOShay]

This is such an excellent way to recycle plastics! Imagine if all 3D printers out there could reuse all the plastic packaging thrown away every day! We need a new machine for 3D printing that recycles all plastics into filament! I'd buy one if it saved money and didn't cost too much.

[@paitor]

Don't know where you are from but usually bottles is already recycled. You even get paid to return them.

[@kc-jm3cd]

Usually they end up in landfills anyway because it’s far cheaper to ship them to third-party countries first world and let them sort through it and just throw it away

[@Daeon108]

Yeah, the sad truth​@@kc-jm3cd

[@alanberickson]

Not sure what you're using as a solvent to get the clean off...... but if it's something nasty you should look at using "Cold Pressed Orange Oil- 16 oz (D-Limonene). Also, can you splice the ribbons together prior to loading in for extrusion?

So essentially your doing 2 things 1 your recycling old bottles into 3d print materials and 2 saving buying mass produced branded "cable" for your 3d printers reducing plastic waste correct ? Would like to know if this is as strong as the commercial stuff

[@T0na1n]

Congratulations man : your project is super clean and well explained Can't wait to try it myself

[@eli84360]

You should add a sensor so it stops when it runs out of bottle after the extruder and doesn't birds nest like that

[@maxpulido]

Small mechanical hand to add tension will do it. Or one of those shopkeeper alarms that gets alerted when a laser by the door can't or can see itself.

[@joseanrodriguez3273]

@@function3D Super, thanks for your complete answer !

[@mangomonad]

Wow, what a nice clean result! Thanks for making this video. One tiny suggestion, you may be able to use a high tack tape like duck tape to remove the adhesive without the mess of a solvent. Try sticking it and pulling it off, or "tapping" with quick stick and tears. Depending on the adhesive on the bottle this can be a really effective way to remove sticky residue.

[@ariyanadumon4549]

Or just use some rubbing alcohol and not risk adding more adhesive mess to the adhesive mess you're trying to deal with?

[@bennylloyd-willner9667]

I think the solvent also gets rid of other dirt so I would prefer that from using something sticky.

It's not very practical, to be honest. Better off just doing what we already do with bottles when it comes to recycling them. Polyethylene terephthalate is a type 1 plastic, recycling it is not a big deal, we just don't do it as much as we should because of negligence.

[@cj.tranzistor]

Great clean job! I made kinda same machine, but when I print sometimes filament foams. Is it because bottles PET quality differs or I am doing something wrong? Did you encounter such a problem? Thanks in advance!

[@function3D]

When it bubbles it is because the temperature is too high, try to lower it, change the nozzle for a CHT clone or no clone, calibrate the PID of the hotend.

[@cj.tranzistor]

​@@function3D Thanks for suggestion! But I tried variety of temperatures, speeds & feeds in testing of course and I think I solved it. It seems like it was hidrolisis no matter what. I was forming filament quite fast. As I lowered speed of pulltrusion letting strip dry quite well, problem dissapeared.

[@hullinstruments]

I don't mean to be a downer... But surely you create more waste (not just time)... But in carbon footprint... Then you could ever hope to take away by reusing the plastic. What if you were to use that same time and effort in something a bit more thought out and planned... I think what you were doing is awesome. I'm just playing devil's advocate. Not only is this a really clean and revolutionary way to process these materials... But also if it's something you enjoy... That is super important. And you're also bringing it to a wider audience who will iterate and create, maybe coming up with better processes or more efficient process. Or just giving people ideas and inspiration in general. That is worth a lot so don't take my discounting and dismissive demeanor to be my full opinion on the matter.

[@hullinstruments]

Holy crap I didn't see the finished product by the time I had commented first. That is super cool! Not only is your process awesome but such a cool finished product and it really does look great. I made a lot of shop tools for my fine woodworking shop out of recycle milk cartons and other HDPE things several years back. Made a bunch of molds, already had the heat presses and stuff from working with knife sheath material... And other thermoplastics..... It was a lot of fun and I use those tools a lot. They will see lifetimes of use and will hold up very well I'm sure. Keep it up! Very cool and inspiring
