Stefan, please be safe about this! Trimmer line is not engineered to be heated by the users to such high temperatures and, depending on the exact additives in the trimmer line and the type of Nylon it's made from, it can release some nasty stuff. Taulman did some testing on this a while back and found that his sample of trimmer line was releasing a mensurable amount of HCN (cyanide) - not enough to exceed critical concentrations, but depending on how exactly it's printed and which trimmer line you get, it could be significantly more.

I used this stuff like 6 years ago before flexible materials were a big thing, and it worked pretty well

[@noahagnew6517]

I've done this with drone parts before, surprisingly way more flexible than most other nylon parts

My first 3d printer back before Prusa started up used trimmer line on a head mounted on a cnc router. It created nasty fumes, ventilation is a must. But, it works great!

I think it’s great that you can pronounce Oregon properly! There’s Americans that don’t/can’t even say it right…. I’m born and raised in Oregon and still live here, so I can appreciate it when people say it like it’s supposed to, lol.

This is exactly what i was wondering yesterday, can't believe i stumbled upon it today. Thanks for the video

[@ultralightpaddling1200]

Growing up in a power equipment dealership, I can tell you that the trimmer line you used is the cheap stuff. Imagine what could be done with the better stuff! Incidentally, the 'better stuff' (Stihl line, for example) might even be cheaper to buy in the long run when purchased in a larger roll. Great job on the video. I can get this type of line for practically free... and now with good reason.

Lawn dads became real quiet when this came out…

[@ZoeyR86]

my first printer was a pure diy Mendel (threaded rod nightmare) and a very early J-head with a peek mount, i used trimmer line, fishing line and ABS feedstock

[@stage4901]

I did this when I bought my first printer, didn't have filament so I used yellow trimmer line. Considering it is nylon with something else mixed in, the smell was unbearable and from that I took the educated guess that it is possibly poisonous. Worked well enough to consider using it again in the future for very specific prints that might require nylon. Wouldn't recommend because of the gas and because after running about 30m worth of line through it my nozzle started to deteriorate, albeit not that much. 10/10 would experiment with other 1.75mm potentially poisonous filament again.

I haven't watched the video yet, but I know first hand that yes, you can use them in a 3D printer. You do have to use specific settings (this was in 2015 so I don't recall offhand) and watch out for steam coming out of the hot end. There is a decent amount of clean up on the prints though. I was using a gen 1ish MakerBot Replicator Dual (can print with two filaments at once). I haven't had to do it since then though, and I have gotten rid of that printer since then. I do know that the nylon-print I made with it were stronger than the ABS I usually used.

Alter! Super verrückt, schon mal gedacht aber cool das du es ausprobiert hast!

[@tigranohanyan3321]

I set my 3D printer with Amazon cheap $50 "fruit dryer" oven located right above the printer. Regardless what I print my filament is always dry. I set dryer ON 2 hours prior printing and keep it ON all the time especially when printing 15 hour printing jobs. I print PETG mostly. I have no problem with quality of my 3D prints.

Printing with the stuff right now. Had 2 out of 12 test cubes actually manage to finish printing. Using a G10 bed that has had the surface roughed with steel wool. ANd that didn't work, so added glue stick. That didn't work, so starting messing with bed temp, and so far that isn't working either - have tried in order 60, 80, 100, 90, 35. Have tried enclosures and that actually made it worse at higher temps as the prints would turn into a spaghetti mess in the top half of the print. And all of this was for a 20mm test cube. I am now attempting to print a cable chain with it - not a print-in-place, individual links. Now trying rafts, the first of which the part warped on the raft, and currently printing the second and the raft has warped to the point that it's hitting the hot end on every pass by that corner and it's a certainty that the print is going to fail. Not going to bother with rafts again with this filament, back to very wide brims. Small detailed parts may not possible with this stuff. I have a LOT of DIY printer failure experience, but right now I am using a slightly modded Ender3 Pro - G10 bed, titanium heat break, capricorn tubing, dual gear extruder. All of that is working flawlessly. It's just a matter of getting this stuff to stick to the print surface long enough to finish printing. Someone used to printing only PLA would throw their machine through a window. Hmmmmm - 25mm brim, .2 layer height, 255C/35C freshly roughed bed and cleaned with isopropal, and that is currently going the bed of all of it so far - nevermind. Last thing I can figure, ditch the feeler gauge I have been using and go back to a piece of paper. LESS THAN A WIDTH of piece of paper. That's how close the nozzle absolutely has to be to have even a chance with this stuff. - 25mm brim, .2 layer height, 255C/35C with 90C first layer temp, 40mm/sec. Gonna try to drop the brim down to 15mm if this one succeeds. No glue stick but the brim seems to be slowly lifting. Yep, delammed. Best results so far. Keeping the 25mm brim, trying gluestick. And let's see if 105C works.... Okay, get the nozzle into the glue and it should stick well enough to finish the print.

[@joeshaver1104]

Posting before I watch but I can tell you... you can 100% trim with printer filament. Found that out by accident since both were red. So it does work. Seemed to last almost as long too.

[@cristi7109]

Stefan, I have recently got a Homers tarantula RS 3D Printer as my first printer from Banggood for around 200$. I think you should have a look at one yourself, it is not a loud printer in any way, I use in my bedroom, I didn't have any problems with it since I got it. I really think you would like some of it's features. Anyway, I really enjoy your videos, they are very helpful, especially when first starting to get into 3D printing. Thank you for all the hard work and all the great content you provide.

[@CNCKitchen]

You're welcome!

[@tylerjohncampbell3846]

Stephan thank you so much for posting! I immediately tried this and my parts are coming out better with trimmer line than pla! I’m shocked not just that this works but how well it prints. Stronger parts that print better for less money? Yes please.

[@anystrap404]

I lost count of the amount of times I've pondered this question about trimmer line! Great video as usual, and I loved the "bonus" stress tests as well. =] Those prints look fantastic!

[@BenEBrady]

Thanks for your promotion of the Raycon ear buds. I've ordered a pair based upon your recommendation... No pressure!

[@MegaTraxxas]

That blue vase looks wonderful

[@CaptSumTingWong1]

Idk why but I've always explained filament as trimmer line, and I was so happy to see this video lol

[@brenthinton6855]

I get my trimmer line on amazon in bulk. it's really cheap at $30 for 5 pounds and my prints come out perfect almost every time.

[@kirkhysell9921]

that vase looked amazing after dehydrating the line

[@1empyre1life]

This is awesome! I have some Oregon trimmer line that I bought for about $2 on clearance a while back that has hardly been used. Time to get printing!
