[@bipl8989]

I want it, but doesn't it look like its a lot of work for a few inches of filament. How many bottles do I have to collect to make 1 lb of filament? In many places, taking recyclable materials from the dumpster is illegal. Be careful about the law.

[@bipl8989]

@@YeneSpace Some city councils sell the right to collect the rubbish to the highest bidder, apparently there's at least some gold in there and as such its become a public resource and pilfering of it is ilegal. I was going to find out how many typical plastic bottles it would take to make a pound, but after I collected 42, the wind kept blowing me off the sidewalk. I guess I'll have to do it the smart way and weigh just one and divide a pound by that. Then I'll know how many I can collect without getting blown down by the wind, which actually appears to be a more useful statistic. 😉

[@markmitchell590]

@@ChickensAndGardening There is no difference. Unless you wanted an additive in the filament this PET is as good as store PET.

[@davak72]

@@markmitchell590 I think the only difference is the dimensional accuracy of the filament. Slicing software expects filament to be a specific diameter (1.75mm, for instance), and if the size is different, there will be under or over-extrusion until you tune the slicer for your particular filament diameter, if it’s not exactly the same as commercially-produced filament. Additionally, and more importantly, if the diameter is not consistent throughout the entire length of your filament, the layers of your print will be of uneven thicknesses, which can obviously be a problem. I’m impressed with this method since the gas stove “glassblowing” technique evens out the thickness across the bottle, then the cutting is made consistently wide thanks to the fixed blade and the weight holding the bottle down. And finally, the motor driving the gear reduction to the spool pulls the rectangular strip through an extruder at a fairly even pace, giving it the best chance of staying consistent in diameter. I suspect the extruder used here is also not too hot, otherwise the plastic would melt and stretch away from the unmelted part.

Recently I saw a guy from Brazil with a very similar idea I believe he makes brooms out of his recycled plastic bottles.

Something that could be done to improve filament "consistency" is making the filament oversized at maybe 1.8mm and then running it through a die of 1.75mm better consistency and nor much sensors or anything required for measuring

[@mr3dp]

There is no need to do this. The final filament is exactly the same size, but the only difference that may exist in some places is the percentage of filament in that part, which I adjust in the 1.5 mm software, which is less than the size it is now, and the reason It's empty filament, maybe you do not understand what I mean I will explain more in the next videos, thanks for asking your question

[@Quantainiumify]

@@mr3dp as the filiment is being pulled into the roll it will have a certain torque and speed but as the roll fills up the outside diameter of the roll will have a faster velocity than the start of the roll so the filiment will be pulled out faster causing inconsistency in the size between the start and end of the roll.

Friends, please be patient, I will answer all the questions in this section : ****The main function of this filament maker is to turn your light into an empty tube, but its emptiness is different. If we consider the width of the strip correctly when preparing the filament and reduce the temperature and speed more, the final filament will not be hollow. -----Can you explain more about the temperature adjustment of this work? Temperature for PET filament production is 225-200, for filament bonding is 270-280 and for printing is 250-260. -----Do I have to inflate and heat the bottles? No, the purpose of this is to smooth the outer surface of the bottle, without this you can also tape the bottle, see in this video: kzbin.info/www/bejne/hpWckJmvfL-Xe7M -----Is this video fa-ke? No, it's absolutely true, all the models made in this channel are produced in the same way -----Do I have to use a 3D printer kit to produce the filament? No, but I used this because I already had this kit, if you have enough knowledge about electronics you can do it using Arduino -----Is there a cheaper solution to this? Maybe, if an easier solution comes to my mind, I will make a video for it -----When will the new video be uploaded? I will upload 2-3 videos in week , so be patient and follow the videos -----What should be the thickness of the tape obtained from the bottle? This is variable. I consider 5-6 mm for a soft drink bottle, which is thicker, and 7-8 mm for a thin mineral water bottle. -----What is the material of the bottle used? I have tested "PET" but ABS bottles cannot be produced this way -----Is the accuracy of the string diameter ultimately good? If the tape produced by the bottle is uniform, the quality of the final filament will be excellent ----Extrusion block, is it a classic 3D printer heater with a filament diameter? Yes, the 12 volt 40 amp heater is related to the Prusa 3D printer and the filament thickness is 1.75 mm. -----Free yes easy I don't think so lol. this is the easiest and cheapest way that I have experienced and seen so far, of course, maybe I will find an easier and cheaper way later, in which case I will put it on the channel and share it with you. To control me, I used the 3D printer board I had before, you can even connect your 3D printer heater and thermistor to it.

[@PhoenyxAshe]

@@hustlesprouts If you are talking about just the part that makes the strips, there are a number of files on Thingiverse available. I've also seen more low tech versions that is basically (pause for several moments of trying to find the most coherent explanation)... okay, take two stacks of washers to the height of your desired thickness, then place a razor/box cutter/etc blade on top of those, then at least one more set of washers over (making sure the holes are still clear. Screw or bolt these to a board with just enough space between the stacks to let the plastic fit through. That's probably the most basic option I've seen, though the first one I saw was some sort of sleeve over a 2x2... and no, my not-yet-properly- caffeinated brain cannot remember how that design was supposed to work. And it will work... but extras, such as the post to hold the bottle steady, and the weight (which I had not seen before, and really like), just make the process smoother and more efficient.

I'm not able to see mr3dprint reply for some reason. Wondering what his details are regarding the specs for the nozzle and other details.

Basically, a tube/pipe the correct diameter can be used on the heated pressed together ends and then slid over the joined section to even out the diameter... then slide the tube to the end. Guessing similar can be performed with that tube cut in half twice so to compensate for the width/thickness of the cutting method with each tube cut in half, so to have a complete tube that can be solder, brazed or glued to some pliers so no need to slide so much distance.

[@TengizAdamashvili]

I've had this idea maybe 6 years ago, and since then I've tried to make filament out of water bottles, with little to no success. I was shredding the bottle and extruding the pieces through a hot end using a slowly spinning drill bit. Thickness consistency was the biggest challenge. Well done man! I did not think of cutting the bottle into a one continuous line. Next question would be, can you skip making a filament all together and print with that cut bottle? might need to make a different drive gear

[@TengizAdamashvili]

@@mr3dp using that cut up bottle strip as a filament directly

[@Wezly]

Nice idea, Adapt the hot end and extruder.. tho this would only work for recycling plastic bottles.

[@Rychlas]

@@mr3dp Hey mate. He was asking whether you can skip melting the bottle strip into filament and use the bottle strip directly to print from without having to make the filament. But if I were to guess you'd have to mod your printer for that. Interesting thought, as you've already made a nozzle/hotend that can melt the bottle strip into filament.

[@Seymour-Butts_666]

The solution to directly printing with the strips has been keeping me up at night. I'm working on a 3d pen that takes the raw strips.

[@Tobyzguy]

@@Seymour-Butts_666 nah, make a whole side setup that takes bottles and feeds it into whatever makes it into strips lol

[@mystamo]

With the utmost respect.. coming from an Engineer.. I smell something fishy here.. Not sure how the plastic is not melting touching the hot part of that nozzle assy you have put together.. Also nearly impossible that you would pull the filament on the other side with the hot extrusion coming out and pull the entire raw materials section into the hot end. Besides, holding the diameter of the filament is done using optics and PID on the reel stepper.

[@micro2743]

Looks fishy to me too, and wouldn't holding it over a stove, just let the pressurized air out, even if it is rotating? Not even a fan for cooling? The yield he got from just one bottle? I have never seen a florescent green drink bottle either...

[@aterxter3437]

A really nice build,.I didn't know the channel, just a few questions : 1) what is the plastic of the bottle in the first place ? PET, PETG, PP ? 2) what temperature do you use for the extrusion ? 3) the extrusion block, is it the classical heater of a 3d printer, for which filament diameter ? 4) is the accuracy in the diameter of the filament good in the end ? 5) have you tried a PID regulation of the tension on the filament ? Different tension will end up in a different diameter in the end, in CNC kitchen's video about a comercial filament extruder, the nozzle have a 4mm hole and the filament get thinner afterwards because of tension. 6) what is the width of the initial ribbon of plastic before extrusion ? 7) last but not least, are theuy any fumes whem extruding and printing ? Thanks a lot for sharing your work

[@すどにむ]

Aren't they normally called pet bottles? By definition they're PET.

[@tasmedic]

Carbonated drinks bottles are almost always PET, and indeed that's what he's using here. If you read the description, the temperatures you ask for are there. I can't make sense of the extrusion block. He has 3 sets of wiring attached. I would have thought just one for the heater and one for the thermistor. Not sure what the third set is about. Plus, the nozzle he extrudes through is a mystery. By rights, it should be 1.75mm. But I've never seen one that size. There are, unfortunately, no links to the cogs and wheels he uses for the extruder. That's a shame. It's still an interesting concept, though.

[@jakegarrett8109]

@@tasmedic you can drill a nozzle to any size, or just be lazy about changing nozzles: I've worn one out to where it was 1-1.3 mm in a weird figure 8 with the outside measuring 1.3mm and the pinched in size being 1mm, started life as either .4 or .5mm and slowly adjusted nozzle size to match in slicer until at that point I decided a $0.25 replacement nozzle was in order. I've also drilled out damaged ones that were smashed at the tip to 1mm and used for faster printing, and the bigger the hole the easier it is to drill so that's not a problem (I also drill out 1.75mm nozzles to 3mm for my other machine since those cost more).

[@すどにむ]

Also nozzle mouth diameter != extruded filament diameter. Nozzle itself could be anywhere in the vicinity of 1.75mm.

[@Iraq3DP]

Good job! What's the purpose of the first two steps, pumping and heating up the bottle? Is that for drying the plastic or to get the appropriate thickness?

[@arvindh13]

so the bottle won't melt quickly at the same time if you heat it too much, there are chances for the bottle to burst or get deformed and it depends on the material.

[@daedalus_00]

I would say it has more to do with the shape of the bottle before it is cut by that jig he has. The pressure puts force pushing towards the outside of the bottle, then spinning it over heat evenly reshapes the bottle.

[@Iraq3DP]

Can save on the PSU and just use something like 10A's I'm guessing to power the controller board an all since the controller board, block and feed motor is all that is needed to be powered.
