i didnt think that would work..... i know no one cares but in my oppinion gas mowers are better..... one of the batteries for that ryobi rider you have costs more that a whole brand new motor for a gas mower. have you ever seen a battery powered rider mower that is more than 20 years old? i have not, but i have seen a 50 year old wheel horse that still has a running original motor. my grandpa uses it every year to till up his garden and plow his driveway in the winter. but hay every won has their own oppinions on stuff i just think battery powered power equipment (like mowers not drills, battery powered hand tools are great.) needs more research and development to actually make me change my mind. but in the mean time ill stick with my scag mower ( the best mower brand ever) for mowing and my husquvarna for plowing
@@DrEckig in addition you want the nylon cord to be wet, if it is too brittle then you can soak it in a bucket of water, that’s partly why it comes pretty wet from the shop and needs a lot of drying before printing.
@@DrEckig this maybe a use for those awful bio filaments, made of algae or beer hops or whatever, biodegradable strimmer line, although you probably get that already.
It's at least part of the reason we have 1.75 and 2.85 filaments as the standard, they correspond pretty closely to the sizes of 2 of the more commonly available string trimmer lines plus a little extra to make up for them being less consistent. String trimmer line is still a semi decent source of inexpensive nylon filament, at roughly 10 dollars a pound. It's good for functional prints that don't need to be pretty, the blades in this video would probably hold up heck of better if they were printed from it.
To bring a side-quest full circle: Someone took clearance weed-whacker filament and printed with it. Took a rather long time in the dryer to be usable, and the resulting print wasn't great, but it worked.
I heard that there are lots of similarities between 3d printing filament and weed wacker line because the first 3d printers printed with them. That's supposedly the main reason why they have the same 1.75mm diameter.
@@Ironclad1313Earlier 3D printers used 3mm filament, the switch to 1.75mm was for higher precision. But yes, weed trimmer line does work, and in the right printer it even works well because it's just nylon plus some additives
Seeing that the riding mower says "REEE AY LMAO" on it: haha funny meme Seeing that all of the powered mowing stuff says "REEE AY LMAO" on it: wow that's dedication
I knew the lopper and rototiller blades were going to explode, and I'm honestly surprised the mower blades didn't. Glad no shins were injured in the highly scientific experiment. 😁 Thanks for sharing!
Trimmer line was used as filament for super early printers before you could really buy filament easily, it's pretty much pure nylon and you can use slightly modified nylon settings but you have to dry it first! Also ventilate well there's some nasty additives in it.
Using filament as trimmer line: it's like discovering that mobile devices can make phone calls. Or, returning to the telegraph by communicating by text.
Thats funny, the first 3D printers actually used weed eater trimmer line. I still use 0.065" trimmer line because its actually NYLON. I buy 2.25kgs of round 0.065inch (1.6mm) trimmer line for about 35usd. You do absolutely need to dehydrate the filament first.
It isn’t recommended for various reasons, some being that it has a load of additives to make it better for strimming that actually make it worse for printing (it affects your printed parts too) and those same additives can release nasty fumes. You would be much better not cheaping out and getting some nylon that is actually meant for printing. On top of that it is meant to be highly hygroscopic, since you don’t want the line to be brittle, if it is brittle you can soak it in a bucket of water. With any nylon the more water it absorbs the more it’s mechanical properties degrade (strength, stiffness, etc), but it’s impact resistance goes up and it becomes more flexible, so when printing functional parts you often really don’t want highly hygroscopic nylon, like PA6, you want something that won’t absorb as much and hence will maintain more of its strength, like PA12. Look at Bambu labs test data for their PA6-CF and pay attention to its wet vs dry properties, there is a huge difference. So even though you can print with it doesn’t mean you should or that it is a good idea, it is optimised for strimming not printing and definitely not for any of the things you print out of it. You are probably better just using other similarly priced materials or just spending more to get decent nylon.
Flymo used to sell plastic blades for their electricv mowers. I used to use them in the 1990's, I went back over to the metal blades, as I had to replace the blades every week, but you only need a bench grinder, to sharpen the metal blades.
I mean weed eater Wire is Pretty much Nylon Filament anyway I'm curious on how the TPU compares or even Nylon Filament to Nylon weed eater wire. Good video!
IIRC one of the big reasons we use 1.75 mm (or is it 2.85mm ?) filament is because it was the diameter of nylon wire that early hobby 3D printers were using as filament, because there was simply no "hobby" 3D printer filament market back then.
The one really big difference (other than material) is weed eater wire isn't circular. There are a lot of different shapes that different manufacturers make, but it's often shaped almost like a torx driver which gives it sharp edges that are better at cutting.
@@junkice6930 it also has lots of additives and is optimised for its intended use case. It is also meant to be hygroscopic since absorbing moisture makes it flexible and better at its job. Highly hygroscopic nylon with loads of additives isn’t something you really want to print with. The mechanical properties of printed parts will quickly degrade too.
@@TheWinjin It's not a complex shape, I just cut it out of a bit of plate I had in the scrap bin. Didn't realise white sparks fly off even when you drill it 😅
Agreed - the joyful chaotic energy really reminds me of early Michael Reeves and William Osman videos. Now that William has a kid and Michael is busy with OTV, I think Emily might be the next great "building goofy stuff just for the hell of it" RU-vidr.
Probably would break even faster, fill makes prints more brittle and in this situation you'd want the blade to be able to flex rather than break. Regular nylon would make more sense, preferably printed from weed wacker line ;-)
I've heard of people doing the opposite, using weed whacker line to print with because it's a lot cheaper. However, it's not a consistent width so it can cause clogs.
@4:00 we've come full 3d printing circle. I remember the early days when people where trying to run trimmer string through their home made 3d printers to try to print nylon items.... now we got this sweet gal, taking printer filamant and putting it back into the trimmer... What a time to be alive.
You can also do it the opposite way around with using whipper snipper filament for 3D printing You need to dry it first, but they’re usually Nylon and at times cheaper per mass than actual spools of Nylon filament I also only know this because of an ADHD intrusive thought moment
I buy filament from this italian brand which makes great colors with awesome printing results. I've just recently noticed that the name of the company from which the package comes is different from the name of the company I bought it from. I check on the web and... they sell gardening stuff, including filaments for weed wackers! I'm now pretty sure someone in the company thought that, since they already owned machines that produce that kind of filament, they would just need to make it with different materials to make filament for 3D printed.
Airless tyre designs work well with TPU. If you want it to work well you don’t want it to look or work like a normal tyre, since you can’t really use air in it instead the flexibility and cushioning needs to come from the material itself.
I like to imagine the agent that approaves Emily's SurfShark ad is friends with Blorpo, the agent that handles Tomska's Surf Shark ads. "Yeah, my youtuber, she just did an ad read with her cameraman and had a small skit" *takes shot of whiskey* "Mine has been under investigation. Twice. Apparently the torture skit was 'too much' but it followed the guidelines. More or less. Kinda"
I know I'm probably too late to the party for this to be seen, but other blades that would be fun to 3d print: Food Processor Garbage Disposal Bladed Coffee Grinder Circular Saw Drimmel Saw. Electric Shaver if you are really brave.
Why didnt you just 3d print a guide to keep the blade at the perfect angle from your shaperning device, aka angle grinder w grinding disc some 3d printed magic and the blades your gusband fails with. A solid blade on a lawnmower cuts the grass, it doesnt brute force rip through and pulverize like what yours is doing
When Emily is standing behind the mower with a safety helmet because there's a 0% chance that something hits her and her husband is in direct view of the blades with a high chance to get hit 😂
The weedwhacker with filament is basically the opposite of old school 3d printing, back in the day some of the first nylon prints were done using weedwhacker string :P
if you are using nylon, I don't see why it wouldn't work. That's what weed wacker wire is made from. In fact, you could just use nylon filament, and make it a giant weed wacker
A friend suggested this a few years ago mostly to try to prevent fires. I think it might work best if it was combines with a sharpenable aluminum edge/framework, 3D printed filler and then a carbon fiber/epoxy surround costing.
Getting L channel aluminium or steel is easy, so that could be used, although you probably want a sharper angle, so just a piece of sharpened flat steel that attaches in would probably work.
Helpful life tip for people who enjoy questionable tips: you can print the trimmer line that weedeaters use. It's just nylon, and is cheaper than nylon filament, but it's almost certainly not as good as PA-12.
All nylons mechanical properties degrade greatly when wet (sometimes the strength and stiffness values when wet are less than half than when the filament was dry), strimmer line is meant to absorb moisture as it makes it more flexible. People avoid PA6 due to how much moisture it absorbs, strimmer line will be even worse. Then on top of that it is full of additives that make it better for its intended use case that aren’t good for printing or for printed parts.
Might of been stalling from spinning too fast being so light. The motor might have a safety on it that is designed to stop if it doesn't detect a blade on it and the plastic blades might of triggered it.
@@conorstewart2214 It's not rocket surgery. You need to really screw them up badly to get them unbalanced enough to cause problems. It's not like a lawn mower is a highly tuned precision instrument or doing 100,000 rpm. You just have to hold the thing at the right angle and do roughly the same number of passes on both cutting edges.
Fun fact, I forgot which specific size of filament it is (either the 2.85 or 1.75) but most weed Wacker line is just Nylon, so you technically can 3d print it. Not even slightly recommend, but you can do it
Where when you get down to it some weed wackers just use plastic string to cut the grass so 3D printed more blades seems like it would work would I recommend?. it probably not
