awesome video thanks man
Finally a video that goes through a wide range of flexible materials! I needed to see this to get a real feel for the spectrum of stuff that is flexible.
Thanks for watching! I'm glad you found it useful.
only 600 subs?? This man needs a YT award for this video.
Thanks! Glad you enjoyed it.
Fantastic filament review! Thanks for sharing.
Great work! Very helpful!
Great work, super review. Hopefully your channel will grow and will be more visible on YT.
This spreadsheet is a godsend, thank you so much! I know it's been two years but if you're still looking for projects I'd love to see a similar breakdown of eco friendly materials!
Thanks Riley! I'm so glad to hear that you found the spreadsheet useful. I actually need to add a few more materials on there that I've discovered and tested out recently from Coex 3D. I also love your suggestion about a similar breakdown of eco-friendly materials. That category is a rapidly changing one (which makes me happy), so it could be challenging, but perhaps it's worth a try! I'll add it to the list of future video ideas and maybe we'll try to tackle it at some point in the future.
Great video! Thanks for making this.
Thanks for watching!
Super nice and refreshing to see someone talking about the sustainability of the materials as a choice factor. Well done :)
Thanks! I just checked out your channel as well. Very interesting content. Sub'd!
second time comin back to this video. good stuff. thanks for sharing ya knowledge.
That's awesome! I love hearing that the videos are helpful. Thanks for watching!
This is super helpful, especially the spreadsheet. Thanks!
I'm very happy to hear that you found the video & spreadsheet helpful. Thanks for watching!
thanks man, you made my day
Thank you for details. I had to watch a few times to get an understanding.
Glad it was helpful!
Excellent work!!!
Thanks Thomas! Glad you found it helpful.
when hes lining them up calling out the names it sounds like some sort of power rangers call out lmao. great video though gives me the info i needed
Thanks Malcom, I'm glad you found it helpful!
I finally subbed hope you can get more
Impressive!! I just bought my first 3D printer, a Bambu Labs P1P. I don't have time for a learning curve and the reviews said this unit was the one to beat. It hasn't disapointed. My 5th print was TPU. I saw all of the videos of how TPU would be difficult. I just slowed down the print speed and it turned out perfect. No stringing at all. Like your prints. Frankly I'm glad I did not see your video before I selected a brand of TPU. It would have delayed me for weeks trying to decide what to pick.
LOL, I'm not usually told that it was good that people didn't watch my videos, but I can see how that would be the case here. Hopefully the video is helpful for your NEXT flexible material selection. Though I have to admit that it's a bit outdated now. I made that video years ago and a lot of the flexible materials in the lineup have been discontinued. Maybe someday I'll have to put (a lot of) time into making an updated version. There are some cool options out there now that didn't exist back then. Welcome to the world of 3D printing, and good luck!
Nice job bro !!! 👌✌️i think this took a lot of time tweaking and experimenting , I appreciate your effort for this variety of roundup
Thanks! I'm glad you found it helpful!
Thank you for your work! It's an awesome service to the 3D printing community. I especially appreciate the spreadsheet. I've had great results printing with both the Sainsmart and the Ninjatek Armadillo. I liked the Taulman PCTPE, but I like the Armadillo better for my nylon-like purposes -- it's just easier to print and deal with in my experience.
Thanks for the kind words, and for watching! I'm glad you found it helpful. I was surprised there wasn't more information about flexible materials out there, so I'm happy to contribute to the community. Feel free to spread the word so more people can check it out as well!
Awesome review!
Please keep up the professional work. Very enjoyable viewing. 🇦🇺🤜🏼🤛🏼🍀😎🤓
Fantastic, I have been looking for this kind of comparison for weeks. I have only ever bought 1 spool of flexible (I am a 3D printing newbie) but would like to try many more... your ECOstruder Flexibles Roundup document helps a lot, thank you.
Thanks for watching! I'm glad you found it helpful!
Your 3 categories make sense to me. Eco friendly is a great goal, keep up your efforts! !
Thanks Steve!
Loved your Video ! Your my go to source for 3D printing info now . As to suggestions , a video on the Armadillo and the Centaur PP those two really interest me . Keep up the good work !
Thanks Robert! I'm glad you like my videos! I hope to do more of them in 2021. I think Armadillo is an underrated material. It's incredibly tough, though print quality is a bit tricky to achieve. PP is still very difficult to print with, and Centaur PP was only slightly more printable than normal PP. To be honest, I'm not terribly excited about doing more PP printing! I prefer Dow OBC for anything that requires PP-like performance.
+1👍 💪 thank you for the detail and the spreadsheet
Glad it was helpful! Thanks for watching!
Great comparison loaded with lots of good info, but I have one question. Can any of the "squishy" filaments be printed using a Bowden tube extruder? I need something really soft and pliable but I don't have a direct drive extruder. Any suggestions would be appreciated.
Thanks for watching! I'm glad you found it helpful. Bowden systems aren't ideal for printing flexible materials, but it is possible. Just go slower than normal, and turn your retraction settings up much higher than you do for rigid materials so it can decompress and then pull out of the nozzle. I have actually had success printing Ninjaflex on a couple different Bowden systems in the past, so give that a shot. If it isn't working well for you then switch to Cheetah for something a little less squishy, but still quite flexible. Good luck!
Well done !!!!!!!
Thanks for watching! Glad you liked it!
i'd like to print some rings and give flexibles a try. is there a specific filament you might recommend that's fairly easy to print with on a direct drive and a good general all-purpose filament?
Funny you should ask--my wife and I both wear wedding rings I printed in Midnight Black Ninjaflex using vase mode! Ninjaflex is challenging, but definitely a good one to master. My watchband is a combination of Ninjaflex and Fiberflex 30D. I like those because of the elasticity of the materials (they are rubbery).
As far as a good general purpose material that's "easy" to print, I'd recommend Ninjatek Cheetah. It's one of the easiest materials to print that is both flexible and strong. Not as squishy as Ninjaflex or 30D, but that makes it easier to print. Good luck with whichever material you pick!
Hello ECO! Great roundup. I usually print with Ultimaker TPU and NinjaFlex... Need help finding any flexible material that is food safe, know any? Thanks!
Thanks for watching! I didn't take note of anything food safe during my roundup of materials. Unfortunately the best thing I can recommend is to use my list of materials and look up each of their datasheets. If you do find some please let me know and I'll add that note to the spreadsheet so that others looking for the same thing in the future can benefit from your research! Also, I do feel like I have to state that nothing 3D printed is ever really "food safe" due to the texture and small cracks and gaps that result from this process. Here's the link to my tracking sheet: docs.google.com/spreadsheets/d/1b6vBvKmKH4-nrBvHnUxQS2-IzaZy_8TyMx8eLnoRotc/edit?usp=sharing
Love the intor XD
Awesome!
Thanks!
what speed did you print at for these and how long did it take you to print that many samples? could you print this on a material/screen like you've shown in the past for cosplay use? i'd love to see a video tutorial of printing with the squishy ninjaflex on a material for building costumes!
Great questions, Scott! The speed varied by the material, and I kept track of that in my spreadsheet. So if you are interested in the speed a particular material was printed at, check it out here: bit.ly/RoundupData. However, in general speeds varied from around 10mm/s for the really squishy stuff, up to around 40mm/s for the more rigid materials.
Yes! In general these materials would work great printed on screens. Some of the more brittle/weak types wouldn't last long, but most of them would hold up quite nicely. I'll certainly consider doing some Ninjaflex on screens in the future--there is a lot of potential for something like that. Thanks for the suggestion!
I’ve been using filaflex 70A for a while, and I’m eager to try the sample of 60A they gave me to see if its much of an improvement.
Oooh, you like to live dangerously! I respect that.
I just picked up a Phrozen Sonic Mini 4K. I would love for someone to do a video similar to this one with resins. This was a great video!
I have used a Kudo3D Bean in the past, and use a FormLabs Form3 now. Definitely a totally different experience between the two (and a whole different price range to match). I wasn't planning a full review, but that might actually be a good idea. I'll keep that in mind!
I'm guessing the "green friendly" ratings are as real as Established Titles.
I’m also interested in the ninjatek cheetah for fpv frame parts ( GoPro mounts, motor guards and antenna mounts) so I would like to see more about it
I have a lot of experience printing with Cheetah on a variety of machines, from small desktop machines such as the Fabrikator Mini (tiny little printer) to the Ender-3, Taz 6, and all the way up to the Modix Big-60 and Big-120X. That stuff is incredibly tough and prints surprisingly easily. My only concern about using it for FPV frames is whether it will be rigid enough to hold its shape. But it definitely won't break if/when you crash!
Wow impressive work well done! Searching for the strongest TPU for drone ducts (not too flexible, just rigid and unbreakable)
Thanks for watching! I'm glad you found it helpful! There are a few good options for a strong, semi-flexible and tough materials. But for something that is both "rigid" and "unbreakable" I immediately think of NinjaTek's Armadillo. That stuff is crazy tough, and not very flexible at all. They consider it an easier to print alternative to Nylon. Give that a shot and see how it works! Good luck!
@@ecostruder Thanks for the advice! Yes I will probably try Armadillo, looks very promising.
Thanks for your efforts & sharing your experiences. However as a relatively new to 3D printing it’s overwhelming. Perhaps I should view those videos with fewer and examples. My 1st personally owned printer will be arriving later this week.
Welcome to 3D printing! It's a good idea to start with PLA as you are learning how to use the machine, software, and what makes a successful print. Flexible materials are notoriously difficult to work with, and I definitely would not recommend starting your 3D printing journey with any of these materials! Good luck with this new hobby!
Thank you very much for this video, very informative! Be aware, though, compostable is not necessarily home-compostable, there is a good chance that the maker of the filament is referring to industrial-composting.
Excellent point! But in this case the materials are indeed backyard compostable (I composted them in my own backyard, in fact). It's important to understand that just because something is "biodegradable" or "compostable" does not mean that it will biodegrade or compost in any environment or any normal process. These things require just the right conditions to fulfill that promise. Thanks for watching!
Question: if I were to print a seat cushion which you do I recommend for somewhat squishy but firm??
Interesting question! Actually most of these "Squishy" and "Flexible" materials would work well for that. The squishiness is really variable based on the amount of infill you use. Very squishy materials with high infill can be just as flexible as moderately flexible materials with sparse infill. Ninjaflex is always a go-to material for me, and would probably make a pretty nice cushion with the right amount of infill. Just remember to print slowly so it doesn't come spitting out of the side of your extruder! Good luck!
@@ecostruder awesome. Thanks for the reply
Thanks for sharing this information. It may be worth getting yourself a Durometer Tester.
You may find this of interest: www.smooth-on.com/page/durometer-shore-hardness-scale/
Agreed. I have one now, but I didn't when I did this video. Very handy little tool!
Thank you. Very helpful. My application is for rc car tyres.
Glad it was helpful!
Great video. As someone who almost only prints TPU parts, this was informative. I’d love to see you test these at higher than recommended speeds to see which ones have the highest speed to quality ratio! I’ve been printing my TPU at 200mm/s with great results.
Thanks for watching! Perhaps if I do another video like this one in the future I'll add that to the things I'm testing for. 200mm/s is ridiculously fast for any sort of TPU--congratulations on achieving that!
@@ecostruder I was only able to achieve that on my FLSUN V400 by bypassing the filament sensor, locating the spool very close the extruder (off to the side) using a magnetically levitating spool holder that can spin with practically 0 friction. The key to fast printing soft filament is reduction of friction anywhere you can.
Another random comment for more traffic on this super great and detailed video.
Haha, thanks for the random comment, and for watching my videos!
Great roundup! A bit mixed up in your presentation, so maybe add a little structure if you plan to review categories of filaments.
Definitely a good reference of flexible filaments!
Thanks cyphre! Glad you found it helpful!
Hey! really great video, so valuable to see comparisons between numerous filaments.
Really appreciate the hustle, I only can imagine how many hours this video took.
I am searching for a grippy texture filament. I already own and love the Fiberlogy Fiberflex 40D. But it is close to not grippy at all.
What would your suggestion? (It is a functional part, so print quality doesn't really matter)
Thanks for watching! Yes, it was indeed a long time to print all of those difficult materials. But it was worth it!
One of my favorite "grippy" materials is Pneumatique. The reason why it's not as slick/slippery as most TPU-based materials is that it has actual tire rubber in it. It's made partially from ground up recycled car tires. This results in a printed part with a very unique appearance and feel. The downside is that it's also pretty stinky when you're printing with it (burning rubber). Obviously, car tires are meant for traction, so it's pretty grippy! Find it here: hartsmartproducts.com/products/pneumatique
@@ecostruder great, sounds promising!
Is any other treeD filament comparable in grip to pneumatique? and worth to put into the shopping cart...
I think "grippiness" would make a great new independent "variable" to be evaluated. Even though it generally increases with elasticity of a material it can vary a lot. Only looking at silicon for example there exist sticky and unsticky variants with the same elasticity...
I also couldn't really find any comparison on the internet... You might sit on a gem here with all your sample prints ;) as such a property isn't easy to be measured like the Shore hardness and really relies on comparison.
@@FabAlb166 Some of the really soft stuff (like FlexMark 7) has pretty good grip, purely because of how soft it is (it is also very difficult to print with). But it's still going to have that slippery feel, particularly when wet. Pneumatique is the most uniquely grippy material they offer, or that I've seen anywhere. Grippiness would be interesting characteristic to track, I agree!
@@ecostruder ok thanks, then I will go for the tyre filament :)
Could you please which materials are squishy, flexible and bendable. It would be really nice to have a list. Thanks.
Hi, I've actually done this already. Check the video description for a link to the spreadsheet showing all of the materials that were included in the roundup (and a few that I added later). Or simply click the link here: bit.ly/RoundupData Thanks for watching!
What would you say is the most abrasion resistant flexible filament?
That's a tough one. Many flexibles are abrasion resistant, but often the more plastic-feeling TPUs are the most abrasion resistant because they are pretty slippery and abrasives therefore cannot get a good grip on it. The softer the flexible material is the more grippy it gets and therefore the less abrasion resistant it would be. I don't have a good feel for the best options for abrasion resistance, but I'd say in general the more rigid options would be best.
HI which would you say is the most rigid flexible.
Haha, well that depends on what you'd consider "flexible" versus what you'd consider "rigid." It's a very gray line. Per my spreadsheet (bit.ly/RoundupData) the most rigid material I tested in my roundup of Flexible materials was Ninjatek's Armadillo. It's a TPU, but it has a Shore Hardness rating of 75D, so it's not very soft at all.
I dont like the categories! You asked, im telling!
Just kidding. Great video 🤘🏻🤘🏻🤘🏻
LOL, thanks for that! I'm glad you enjoyed the video.
I just love the video, awesome knowledge, just ditch the background music man, I wanna focus and hear what you are saying and that music is coming in a way
Thanks for watching, and for the compliments on the video. I appreciate the feedback on the background music. I generally try to keep it low enough that it's not going to interfere with what I'm saying, but it seems like I may have missed the mark on this one. I'll keep it in mind for future videos!
I've only printed 95A really. I want to get into super flexible materials. They're just so expensive!
95A is a great place to start. Rigid enough to push through the hotend without too much drama, but soft enough to give you the benefits of a flexible material. The softer it gets the more difficult it becomes, but man, the first time you print a super squishy part it's soooo satisfying. :-) Sounds to me like it's time for you to make the leap into squishy materials!!
@@ecostruder Yeah I def have no concerns about tackling the difficulty, I just don't want to pay $60 for 500g of 60A. 😂 I found some 83A for $37 per kilo and some 75A for $45 per 500g, but dang.
@@802Garage Gotcha. Yeah, beware of cheap TPU. That stuff is hard to make, and even harder to make with good quality control. Whichever way you end up going--good luck!!
@@ecostruder Surprisingly, my Longer brand 95A for as little as $16 a roll has been fantastic. I know I can't expect prices like that for anything softer though. I'm just broke and cheap. ;) Thanks for the video! If you could do a condensed faster version of this updated for 2024, like maybe a "Top 10 flexible filaments in 2024" I bet it would take off.
What would be your recommendation for a durable, not too squishy nor too hard, filament for designing of dog toys? For large breeds 600+ ft.lbs. of bite force? Tree D appeared to be a good choice.
Dogs tend to bite toys in an effort to pull them apart. In my experience they will eventually be successful in tearing off some part of pretty much any toy if given enough time, and then those bits are usually swallowed. For this reason I cannot suggest allowing a dog to chew on anything 3D printed unless it is rated for ingestion (and I'm not currently aware of any filaments that are). I'm sorry, but for the safety of our canine companions, I would strongly discourage this idea.
@@ecostruder I've found in twenty years of breeding and raising German shepherds that NO toys are impervious to some dogs, not the toughest Kong balls or numerous other tough quality brands. Certain dogs I've owned will completely destroy lifetime guaranteed stainless steel dishes with rolled edges, crush door knobs like tinfoil, etc. But many of my dogs like to retrieve and actively play with the handler without the need to destroy the object, and when playtime is done, the toy is put away.
I'm only asking for a good recommendation for a filament that is similar to products you'd find in your average pet store. I wouldn't ask, but I have zero 3d printing experience at the moment, and I certainly wouldn't hold you accountable for any guidance you provide. There are numerous products that I consider unsafe (and likely to be ingested) that are prevalent in today's market, especially ones presented as "chew toys", like rawhide or ropes.
You can trust that I am a responsible dog owner, only seeking and expert's advice on the most durable, hefty, resilient, and non-abrasive substance that I could use in this situation. You wouldn't advocate against someone wanting to 3d model Legos or green army men because of small children or barefoot adults, would you?
@@darylehret I appreciate the additional comments and context. Speaking as someone who had to pay a LOT to have part of a plastic dog toy surgically removed from my dog's digestive tract I can certainly agree that not every toy marketed for dogs is safe for them to chew on, either. Most flexible filaments are Thermoplastic PolyUrethane (TPU) and not true rubber. Some market themselves as a Thermoplastic Elastomer (TPE), but that's an umbrella term which includes TPUs underneath it. Keep that in mind as you select a material for your dog to have it its mouth. As for a tough flexible material, most TPUs are fairly capable of withstanding abuse. I'd say that, in general, the less flexible it is the least likely to be torn apart (if printed properly). So you'll probably want to look at the upper end of the Shore A range (90+) or around the 50-60 range for Shore D. I'm personally a big fan of CoexFlex 60D. It's not available in a lot of fun colors, but it's a super strong material and it prints beautifully. If you want lots of colors I'd look at Ninjatek's Cheetah for something in the same range. Lastly, it would be unfair if I didn't at least mention that flexible materials are some of the most difficult materials to print on most printers. If you are new to 3D printing I'd highly recommend starting with rigid materials like PLA or PETG before moving on to flexibles. And definitely make sure you use a direct drive printer, rather than a bowden machine like most of the entry-level printers tend to be. Good luck!
If you ask anyone in the FPV drone community they all agree that Sainsmart is the best TPU ever, tough as nails it can take the beat like no other. Strange you didn't mention it. I think like you said the best flexible is the one that works for what you need.
Funny you should mention that. Check out the tag on the sample at 24:08! Sainsmart's material is fine, but I haven't found it to be particularly different from any other generic TPU. TPU is extremely tough, so I can see why you'd like it for drone frames! We've recently been using a lot of CoexFlex 60D, which is so good. Might be a good alternative to Sainsmart TPU! But yes, the one that works is the best one!
I’d like to see more on the ninjatek armadillo!!! I’m looking at printing some whoop style frames and it sounds like it could take the punishment but would like to find out as much as I can before putting my money into it
Good call! Armadillo is really interesting stuff, and I think it's mostly overlooked as an alternative to Nylon. It might make an interesting video to prove that out by putting it head-to-head against some of the high quality Nylon materials from @Taulman3d!
Do you have printer settings for the Ender3 V2
Unfortunately not. I'd just take a look at the manufacturer's website to see what they suggest for print settings. I haven't tried printing these materials on any Creality machines so far.
So which one is the most flexible and stretchy
Thanks for the sub! Check the description for the super nerdy spreadsheet where I list out all of the types of flexible materials I tested and compared. I rate them both by the stated Shore Hardness Rating and also by my own personal opinion by feel. Flexion's X60 is so flexible and stretchy that it's nearly (but not totally) impossible to print with. Check the spreadsheet for the details!
ECOstruder how well does it work with a 3D pen and how much does it cost
@@craftanything8041 Wow, a 3D pen?!? I haven't ever tried printing flexibles with a 3D pen, so I really can't say for sure, but I wouldn't expect it to work very well. If you do end up trying it be sure to report back on how it went, and what pen you're using! As for pricing, X60 is a bit spendy. It's $99 - $120 per kg, available from flexionextruder.com/shop/x60-ultra-flexible-filament-black/. I wish you the best of luck!!
ECOstruder that’s out of my budget range maybe you could try it in a video
Your spreadsheet is commendable and I appreciate the time you put into this project, but the video presentation isn’t well organized, being flawed by considerably too much jumping around. Filament comparisons in general could be improved by including more objective data, which would facilitate comparisons to filaments presented elsewhere.
Thanks for watching! I certainly agree that there is always room for improvement, and appreciate the input to help make future videos better.
whats the file you used
If you are referring to the Tire model I used, it's this one: www.thingiverse.com/thing:33160. I scaled it up for my testing purposes.
This should have been a series of videos. With better or more info. And testing to failures.
I'm sorry you didn't find the video to be thorough enough, but thanks for watching anyway! I certainly would have loved to do more, but with this many materials and only so many hours in the day it would have gotten out of control pretty quickly.
spin them up - if you have so many tires - try them actually rolling and transmitting some energy onto some drum with generator and energy transfer meassurement...
Haha, that would be very cool. Unfortunately, while I have the tires, not all of them are in great shape, and none of them have any wheels to go on. But it's a cool idea.
I generally have better luck printing flexibles at the lower end of manufacturers suggested print temps. CR10S Pro V2 with upgrades including Bondtech DDX
Great feedback! It's always interested to see how different machines handle printing different materials.
idea: adding air bubbles into the body, to create Foam, (rubber-Foam?)... that would make this all even softer and more flexible
Varishore now exists and it does exactly that! Good call!
You should do a video on that @@evanlane1690
only 820 sub?? What?? This was what i needed. I wanted to print a shoe sole that is enduse, I think Ninjaflex will be the best for me.
What do you all think? Should i print with ninjaflex or not?
Glad you found the video helpful! Ninjaflex is awesome, so I'd say that's a good call for your shoe sole. You might also consider TreeD Pneumatique since it has actual rubber in it and would be much better for traction. Ninjaflex can get a bit slippery. Good luck either way!
Epic! Any “food safe” flexibles? Any bio degradable + food safe ones? (Yes I know the 3D printing proces is not food safe and so on)
Interesting that you should ask--I just got this question from another viewer as well. Unfortunately I wasn't looking for food safety when I was doing the roundup, and I don't recall seeing anything about food safe in the material descriptions. Also, I'm glad you know about the issues with 3D printing and food safety!
Thanks. Well, perhaps the compound(s) that make TPU and TPE flexible are not food safe.
@@ecostruder While searching for a review of food grade flexible filament, I found your really good video. Thanks! From your excel, it seems that the shore grade does not mean much in terms of 'squishiness'. I am wondering if there is another parameter that would help determine that? Here is the product that I wanted to see a review of before buying it since it is food grade and skin safe: fillamentum.com/collections/flexfill-tpe-flexible-filament/products/flexfill-tpe-90a-natural
@@virtualpaul1 Yeah, it seems like each company tests their materials to determine the Shore Hardness rating in a different way. It's kind of frustrating. As you can see, my "feel" testing did not align with the Shore Hardness testing. There doesn't seem to be a good way to determine what the true "squishiness" is without just trying it. Filamentum's Flexfill TPE was one of the materials I tested! It's a nice material that prints fairly well, but does have a bit of warping when it cools. I still maintain that anything FDM 3D printed isn't food safe. But if you can put it in an autoclave to sanitize it then you should be good. Good luck, and thanks for watching!
@@ecostruder Thanks a lot for taking the time to answer! I agree that food safe is not easy to believe. I bought a stainless steel nozzle to help. Supposedly the brass nozzles leak some lead. Since I did not see the Flexfill TPE in your list/excel, I am wondering in which of your category you would put it (squishy, flexible, bendable)? Or was it in another video than this one perhaps. I have subscribed so maybe I'll see it eventually.
What would be the best for a
🙄flashlight🙄
A flashlight's housing is usually pretty rigid, but if you are concerned about dropping the it and having it break then something that is rigid, but also impact resistant would be ideal. Anything in excess of Shore 100A should work well. Ninjatek Armadillo, CoexFlex 60D, or similar rigid TPUs are good options for that. They are essentially replacements for Nylon at that level of rigidity.
@@ecostruder not that kind of flashlight lol 😂
If you know what I mean
@@Katudon-xf7kt If you are asking about a material that could be in direct contact with skin then I'm afraid I can't help with that. I didn't look into the specific approvals necessary for that type of use.
Great video! Hats off to you that you managed to get through the video with a racoon stuck to your chin! ;)
Ha! Glad you enjoyed both the video, and the beard that was featured in it!
Glad you saw the funny side. Interesting video indeed!
Hey I’m a Hart with a beard too!!!
Brother!!!
2n d Idea: adding a honeycomb structure internally...that would also make it softer and much more flexible, and in addition more durable because of the perfect distribution on any kind of external physical impact to a honeycomb structure... R, Akos Simon
You are absolutely correct--including more holes in the interior (or even exterior) of the part would increase its flexibility. In fact, 3D printed parts are usually partially hollow on the inside, so this would already be the case. The flexibility of parts can be varied by increasing or decreasing the infill percentage, or by increasing or decreasing the number of perimeters of the parts. This has a huge impact. That said, if the parts themselves have very thin walls and very little internal volume there isn't much of an option for this type of thing. Thanks for the comments!
You spent WAY TOO MUCH TIME on Eco-Friendliness.
LOL, I'm sorry you feel that way. This is the ECOstruder RUclips channel, though. We are all about Eco-Friendly 3D printing!
God, so boring
Sorry you didn't like it, but thanks for watching anyway!
Then go watch something else, that was rude.
