Say Goodbye to Old Filaments - Meet the Game-Changer of 3D Printing!

[@Hotwire_RCTrix]

48% stronger and 1000% more expensive. Just use TPU for the bumpers everyone.🤨

[@greenman360]

Yep. Harder TPU, like 72D or something is pretty indestructible.

[@JimMassey-g7z]

That's the trouble with reviews from people who didn't pay for the filament. He's not wrong that the filament is great for scenarios that it's most suitable for, but the fact that it's ridiculous for situations where ABS or ASA (or even PLA/PETG) would just as well. It's pretty incredible material. For the price, however, it still niche. I'll be glad to start seeing comparison between this new filament and other 'engineering' materials like PA6/PA12 (GF and CF reinforced), since they are all around the same price, give or take.

[@Hotwire_RCTrix]

Race drones have been using TPU for years. As long as your printer has a direct drive extruder it's easy to use.

[@antonkukoba3378]

@@Hotwire_RCTrix there's probably no mainstream printer built after 2023 which can't print TPU

[@JThelen1031]

Goodbye to old filaments? Not at $200 per kg it's not. It's certainly an interesting material, but I'd rather stick with some type of fiber-reinforced filament given the price.

[@Sharpevil]

Does fiber reinforcement actually make pieces any stronger, though? My understanding is that the carbon fiber is chopped far too short to provide any real strength, which normally comes from many long parallel stands of carbon fiber. Instead, the carbon fiber adds stiffness and dimensional stability.

[@eighty-eighth_section]

​@@SharpevilYes, it does. Stiffness/modulus is one measurement of strength.

[@TheSolongsidekick]

@@helli3088 Uhh maybe, go look for it, seems like the thing there would be a billion variants and similar designs out there. But I still wouldn't print it with an FDM printer if you can avoid it, a tough resin like Blu with like 10% flex resin mixed is going to be exponentially stronger. No layers to potentially delaminate and way more watertight as well. You can get good resin printers for under 500 bucks these days.

[@jimmanis6717]

Having it print at a different orientation would minimize the tip breakage seen. What you had was layer separation, I know you probably did it standing up to allow it to print without supports but canting it to a 45-degree angle or such would eliminate the layers running along fracture angles.

"I watched a guy print an elephant figure and then stand on it" So? Tests have shown even a screw thread printed in PLA can hold up to 50kg, you don't need special filament for most purposes. And on top you don't risk your lungs with carbon fiber dust.

[@kccrawler4624]

Never seen a rock racing boat before! Love it!

[@ddegn]

I read your comment before watching that part of the video. I had scroll back so I could like your, very appropriate, comment.

[@MarkG-h2y]

The filament is PPA-CF - a carbon filled nylon. $150 per kg. Requires a hardened steel nozzle, an enclosed printer and a filament drying set-up. Tensile strength gains are highly dependent on print and filament quality and the best gains are 50% - many videos discuss this.

[@TheStigma]

PPACF stands for Polypropylene Added Carbon Fiber. This is pretty self-explanatory then, assuming you already know what PP is. It's one of the most used plastics because of low cost, ease of manufacturing (injection molding), sufficient rigidity and being cheap. Any type of plastic bucket or box basically uses this - and a whole range of other objects. Carbon fiber adds extra strength and rigidity, while PP is already excellent at resisting almost all chemicals and moisture. Pure PP has issues with shrinking and warping as it cools if you print with it - making detailed parts difficult - but carbon fiber reinforcement reduces this problem greatly. The caveats are you need high heat to print it - so some less expensive printers will need a little modding. An enclosed printing space and thermal control would be a must - but that stuff is DIYable withhold breaking the bank. Secondly, like with all filaments that use fiber reinforcement it will be rough on nozzles and wear out standard brass ones fast. You need a higher grade of hardened steel or better if you are going you use this on the regular. I don't have personal experience with it, but fiber reinforced plastics certainly have a lot of potential for strength.

[@soma_rc]

Avoiding cf filaments here for now. These chopped fibers are very small and not always well encapsulated in the final print. Not convinced there are no health issues. Further tests show little improvement over the base material properties.

[@conorstewart2214]

There is also no evidence f any real health issues either. How were you testing the material? Holding the same print in both a fibre filled and non filled material you can clearly tell a difference in most cases.

[@soma_rc]

​@@conorstewart2214won't deny the prints are lighter or have a different look.

[@guruthossindarin3563]

I make some extremely high-impact parts and might give this material a try. That said, I wonder if you have tried PETG-CF. PETG is stringy and flimsy, but has excellent layer adhesion. CF of course is very stiff and strong. When paired together it makes a very strong combination that is stiff but resiliant, easy to print, and doesn't string. Not as high-temp as PA of course, but better than PLA. Cost $46/kg.

[@Gallardo6669]

The boat: incredible! Thx for the video

[@scalebuildersguild]

Thanks for watching!

[@GeddyRC]

For $100/0.75kg it’s got to justify the price of printing parts you’d normally buy. While a gear is a good strength test to a degree, you’d really need to run it for many long hours before concluding if it’s as strong as a regular composite gear which would probably cost between $4-8 depending on the vehicle. The fact that it doesn’t implode immediately does make it test better than other common filaments but still, $100 and it needs to print enough parts (and be at least as strong as them) to outweigh the cost of just buying replacement parts. Very interesting nonetheless, I’d be curious to see how it works with parts like a-arms, wing mounts, but still those parts are usually pretty cheap (or, you print them in high infill TPU and they’re indestructible). Bit of a brain dump this morning, haven’t had my coffee yet.. I like that the industry is experimenting with different materials, trying to find optimal use cases for them all while keeping the price cheaper or at least on price parity with injection molded composite parts is what we’ll figure out in time.

[@scalebuildersguild]

I like that there are always new innovations with 3D printing, regardless of the hobby! I agree, it's not cheap, but in the long term- if everyone had a 3D printer- we could (in the future) probably print our own replacement parts for things that would normally end up in the landfill. Maybe I watched too much Star Trek Next Generation in my youth, but those replicators were amazing!

[@Noxoreos]

I would argue that you would not just print every piece out of this material. The best comparison would be if you have a use case where you actually want a metal part and this material may be used instead. Getting the required part 5-Axis-CNC machined would be much more expensive. The requirements of the project tell you what you need and to stay cost effective it is a good idea to choose a suitable material. If you don't need the stiffness and impact strength or heat resistance then it's just the wrong material. But if you do then you do then it is nice to have. Also no one says that the whole part needs to be printed of this material. Lets say you need that heat resistance because it contacts with a heated part, then you could just create an interfacing piece from this material and the rest from something cheaper.

[@BramCohen]

It seems like a fairly typical nylon with the exception that it legit has better bending modulus than PLA. The big questions are related to that: How toxic is it? How much of a pain is it to dry? How much does it tend to creep?

[@PirateWasHere]

Gonna be honest i just stumbled across this channel so im not sure of your 3d printing knowledge but there are many methods to make some very strong prints using some very cheap filaments such as ABS, ASA, PC, Nylon, etc. As far as body panels go there are also cheaper semi flexible filaments such as the harder TPU filaments that will retain shape and take a hell of beating. You mentioned you have an X1C i would recommend looking into multi material prints as well. Just some friendly advise from someone whos deep in the 3d printing world hope this helps at least someone here

[@outcastrc8052]

Game changer for sure!!!

[@amonkeyrc1387]

Maybe I missed it but did you discuss on the health issues that come with CF materials? It has been shown that the micro carbon fibers are dispensing into the air while printing. And even when the object is done the fibers will abrade into you hand until you eventually swallow or inhale them. CF unfortunately is not without issues. The only way to prevent it is to paint or glue the surface as you usually see with all the industrial manufactured CF parts.

[@scalebuildersguild]

I've read other claims that is mostly debunked at this point.

In fdm, perimeters matter more than infill for strength according to tests. Even maxing out perimeters for a solid print can be stronger and take less time printing than 100% infill.

Polycarbonate or PC is the strongest best value for money filament. Downside is it requiring an enclosure. PC CF overcomes this and is easier to print, but its layer adhesion isn’t as good as straight PC. Also not sure I want to use Fibre filaments after watching Nathan Builds Robots video on the topic.

[@bbc92314]

You should not listen to someone that doesn’t understand nano tubes versus ground up cf. next pc has nothing on ppa. Some of these comments are mind blowing .

[@Noxoreos]

You could try to print every other layer with PC-CF and the others with normal PC. Maybe that improves layer bonding. I wish there was such a setting in orca slicer, but you can do this via custom color changes after each layer in orca slicer. It's just an idea, i have not tested it myself, yet.

[@Brocknoviatch]

Can you try using it in small printed tools? Like allen wrenches or screwdrivers? Or scissors/knives and see how well the edges hold? Maybe also see how good it is at replacing common weakpoints in prints. Could be good to keep around to use here and there (sparingly) to reinforce certain parts of prints that are failing like in some more complex mechanisms for example. Also could maybe be good as a rigid skeleton to slap other weaker/cheaper/faster printing materials onto.

[@createsomefun]

I offered 3d printing services with a Markforged Onyx printer for years. The issue is people dont want to pay the extra cost for the quality. Its often not viable to print a part that you can jist purchase for less, unless it means you can provide it locally or it is a custom part.

Search "MJet" on CG Trader!

[@noahkatz9616]

Something that is often missed is the relationship between stiffness and toughness. If two materials have the same strength but one is half the stiffness, it will have four times the toughness. This is because the material is acting as a spring and the energy absorbed by a spring is proportional to the square of the deflection. So toughness, which is the how much energy can be absorbed before before failing, is maximized by high strength and low stiffness. [edit] Actually, that's not quite correct. The formula for the energy stored by a spring is E = k * (x^2) , where k is the spring stiffness and x is the deflection. So with half the stiffness and the same applied force, the deflection will be doubled, and E = 0.5k * (2x)^2 = 2x^2, or in other words, toughness is doubled.

[@boogalooman]

Sweet material, I love new engineering materials to test out. The price comes with quality filament, its expensive but usually worth it depending on your application. Heads up on printing gears with carbon fiber material, you may end up with excessive or premature wearing of that gear (more likely whatever its touching) because carbon fiber is abrasive so it will essentially grind away at whatever gear its up against. A normal Pa6 or Pa12 would probably work better for the long run, in my experience.

Thanks for watching! She'll never agree to being part regularly, but she was a good sport, that's for sure!

Good video! Just wanted to add watch CNC Kitchen and My Tech Fun as they will give you insights to the strengths of each filament, PLA is one if not the strongest you can get however its impact strength is lower and in your case friction heat is way to low as PLA does not like to rub on other materials, but it will out hold better than any other filament under certain conditions temp and high load for extended times is not one of them. Another thing to think about is larger layer lines and an extra 10-15 degrees past normal printing also will add strength by better adhesion between layers but visual quality drops off. Its great they are really pushing what is possible with FDM printing.

PLA is “strong” but it really doesn’t come close to filaments like these especially when you take into account the other mechanical properties too. When printing things like gears then visual quality matters, any imperfection that you can see will likely be a surface imperfection that will effect friction or wear or how the gears mesh together.

@@conorstewart2214 that is very correct

Have you tried the paht-cf? I've been using it for all my parts that need extra strength and it works great....much better than pla-cf.

[@Defnot_mattchew]

How does it print compared to PA6-CF?

Which skidplate was that? Looks like ifs2
