Hey Joel, me and some fellow students made a fdm 3d printer capable of printing solder tin! It can also 3d print all kinds of filament we already know. It was a assignment for college, and we smashed it! We only had to build the head, but we built a entire printer! If you want to check it out watch this video (I'm sorry, its Dutch, but there are some cool shots in there!):ua-cam.com/video/NlZ5NamzZaQ/v-deo.html I can talk about this thing for hours, but I won't waste your time further😅
The Nimble is amazing. I run flexible materials on my PLA profile. Retraction and all. Brian and Lykle are also super nice guys and they take the time to really talk and listen to their customers.
this is a very amazing idea that Delta and corexy printers could benefit a TON from! but to benefit from it you need a 32 bit printer or a 8 bit one running klipper, because the regular 8bit one can't manage the speeds you need to print fast you should try it with that and crank the speed to 200mm/s at 2k acceleration (with a good hotend)
This is definitely eye catching. On a tablet right now and the Nimble site is not wanting to cooperate. Will try again once I'm using my laptop. I think, other than 3D printing jumping to the rescue, I really enjoyed the 3D printing family and dogs in the background. Gave it a lived in feel. I mean, the man's glass wasn't even on a coaster! Thanks guys this is nifty stuff!
Ive had the double nimble for a Chimera on my CR10 5S for about a year now. Ive ran probably around 30 spools of filament through it. ABS, PLA, flex, elastic, nylon, ASA, PC etc. I have never had any issue with it. works perfect. I have a 1600 watt keenovo heated bed with an enclosure and it get hot in there and the nimbles hold up fine in the heat.
Oh boy! That raises a lot of questions related to physics: When you transfer the rotational movement from the external motor via that metal cable inside that tube, won't the metal inside that cable be slightly twisted in each direction? Kind of like lagging. (Imagine a steel wire, and put two handles at each end, now you can "twist" the wire quite a bit), I can imagine the same happening here.
I just ordered TH3d Tough Extruder, but this might be on the buy list before it arrives. I love the idea of printing flexibles at normal speed, I fell in love with the Pneumatique by Treed in the Maker Box a couple months ago and want to use it more but the print time is a major detractor. I like the 'remote-direct drive' title, it fits and works.
@Nic Franco My first attempt was with a .4 Chinese brass nozzle and all Vanilla Ender 3 (save for PTFE tube), at 20mm/ sec I got _very_ good results (used the FatBottum TPU preset in Cura 4), absolutely satisfactory. I tried some pieces with a .8 nozzle that actually turned out worse by my opinion. The stuff is STRONG! I haven't tried every material or brand, but for all around toughness, this seems to be the toughest material I've personally handled (in normal conditions).
I wouldn't call in an innovation when there was already a product on the market doing the exact same thing years before the Nimble was launched. Google Flex3drive.
If I ever get around to building a small corexy, I think this would be perfect for it. Also, I love the dogs barking and I think I heard Mrs. Nerd yelling at them.
This product is honestly so cool and pretty innovative. I’m actually hoping to buy it when I get some more money. The only thing I could help but notice is that it looks like they left the protective plastic on the Ender’s screen
That is awesome although I would have loved to see that on a printer such as a delta or similar. That being said this concept is a game changer for 3D printing especially if you want a light head.
Sonofabitch😲 I tore apart the cable actuator from my bench grinders dremel tool to do the same fn thing and find this. Lol at least I can buy a finished product now.
So the motor is on the frame connected to a flexible shaft and it in the hotend head is the extruder. This is better than the bowden system but remains behind direct driven. Probably you will have backlash problems too unless the flexible shaft has a good couple to the motor and the extruder and has a very good quality, which it's expensive. The big advantage of this system is you can print flexible materials without a direct driven extruder.
Wow, great invention! Finally the advantages of direct drive and bowden designs combined! I wonder what's Angus gonna say about it, as he doesn't really like bowden.
Hey Brian, if you are still reading the comments, just curious. What is the backlash like with the drive system? Is it something you would have to account for in the retraction settings? This is a very cool idea! I have a flexible drill extender I've used, but I noticed that it has a lot of backlash as the whole tube tries to move when it starts/stops. I am designing a mostly 3D printed printer, and have been looking for a lightweight head to put on it, yours definitely fits the bill.
I love all of your video’s and you have inspired me to design objects and to upgrade my 3D printers with ease because of the knowledge you have given me
FYI to anyone interested in buying one of these, they're currently a month out on shipping new orders due to parts shortages. These videos are driving them major business!
acting if he knows his stuff ask about where the nimbles actually innovated from no credit to the original product it came from open source if i had time and money i myself personally would want to sue brian and his friend lyke, i undestand they done a good job making the product but they've made it on the back of someone else hard work
3D Printing Nerd I watched it again and saw that he has a 30-1 gear reduction which should help that. I just know from the mechanic world how those types of cables can tend to twist when put under load.
As a recent buyer of a massive delta printer, I am, to say the least, intrigued. I'd been wondering how much modding I would have to incorporate to use some kind of feed system like a mig wire feeder where I have a body of experience to get a remote feeder in place so only the heat block would be swinging away on the head.
So it's like a flexshaft tool that powers the extruder so they can take the motor off of the moving head. That's a good idea. I wonder how much slop the flex shaft introduces, which I would think would mess with retraction a bit.
They didnt mention the error in the flexible cable. The twist at one end is not the same as the other end. There is a loss, and that loss may be similar to the losses in a boden tube setup. He should have done the analogy for AC current. Instead of a rotate through the flexible cable have it push 2mm, and retract...push 2mm, and retract. The receiver could be something like a push ball point pen, so every push causes the mechanism to work, and the mechanism delivers a perfectly metered 2mm.
Fascinating! I wonder what the down-sides are to this extruder.. Like is there any extrusion-rate accuracy loss with that flexible drive-shaft? Like if it's doing lots of retraction moves? Is there any give when 1 side of that drive-shaft turns, vs the other side? Or is it real solid/instant? Mybe the term is latency? Is there any latency or tolerance between the movement from 1 end to the other?
Great job both of you, best demo of on-the-fly 3D printing creating useable parts. I've just bought a CTC i3 clone for $99 Inc Honey App $5 off, this supercheap printer *flies along* & is producing quality parts at 0.1 LH/ 0.4 nozzle. 1 key to this surprising result seems to be the Bowden tube-free extruder (I get strong HB adhesion painter tape on glass) so I'm looking forward to seeing if my
@@Evilslayer73 was it 400% normal speed or 400mm/s I cannot remember now, either way it is very impressive, and while I hope for their sake people don't rip off their idea, I also hope it brings forth a new wave of innovation in the market, I can personally think of a different way to do light way direct drive extruder without using a flex shaft, if it is a practicle idea or not, that is a different matter all together...
A solid driveshaft with motor mounted at the end of the X gantry and a sliding gear at the extruder would be a simpler solution. Doesn't need the crazy gearing, no problem with cable winding direction. The speed on a bed slinger is going to be determined by bed weight anyway.
I have one of these connected to my Duet/Smart Effector Delta, and I have to tell you my experience differs from the claims of this video. I can print flexibles if I go very slow (no more than 20mm/s better at 10mm/s), and use NO retraction, but I don't find it to be much better than the bowden setup. The breech is nice, but it can be a bit fiddley when there are connectors in the way (you could kind of see that in the video). I use magnetic balls to suspend my effector, and a lot of this extruder is metal, so pretty much every time I change filament, the breech arm comes off and stick to one of the magnetic balls, and when printing, the drive cable slaps and sticks to the magnets on the pillar when it is in range, and pulls away kind of vibratively when it pulls away far enough. I'm still on the fence as if this is a worthwhile upgrade.
I was really excited to see this when Tom visited the booth. One of the biggest problems I have with my printer is that it's so big my bowden system is about 800mm long, which makes retraction settings a bit of a nightmare and since it's a corexy system I really don't want the weight of a direct drive system. I suppose my biggest question is if there will be different shaft lengths and stiffness available? What I would probably do is: mount it so the motor is up above the printer so there would be very minimal flex in the drive shaft unlike when it's mounted on a Cartesian system like that Ender 3. Edit: I see there are different lengths in 75cm, 95cm, and 120cm on the site. Why is the 75cm the same price as the 95cm? I hope you guys can get a deal with Matterhackers or other options to be an over seas distributor to help with shipping times and costs. Now if only I could afford it when it is in stock...
My Zesty Nimble seems to have stripped the plastic gears or something, it clicks and doesn't feed. Are metal worm gear sets available? It worked great for a few months then went to crap.
Looks cool but everything is a trade. The twist in the cable drive may cause extrusion/retraction issues but I would guess they are minor. This is probably a good trade off given the other benefits.
It does not twist the head, the sleave counteract the force, as the slece is fastend at both ends. and if it did the force is 30 times lower than the force on a normal extruder, as the gear ratio of 1:30
Do you think this kind of system could work if it were 1.5-2m long? I know they don’t sell it that long but considering buying my own cable and tube to make my own for my very odd machine
Hey Joel. We talked a few years ago at Portland Mini Maker Faire about the Wanhao i3. I'm happy to report that I'm still 3D printing today. I'm not sure how often these comments are read, but I'm looking for information to put in a college report and was wondering what the best way to contact you would be.
This is really igenious. This could really help printers like the cr-10 and if working well could really help artifacting in prints as the head is so much lighter. Im impressed. Sounds like my new upgrade
It appears that you can change out filament to a different color very quickly. How would this one compare to your normal extruder for purging. Currently having to have a purge block. Can this be eliminated.. that would be awesome or even timed in the g-code. Thanks
Yeah, but that's probably trademarked. They could use a similar name but differentiate it as being a 3D printer product. Perhaps..hmm.. Flex3drive? Catchy.
When I saw this video come up I thought for sure it was you putting this on you’re Artemis! When do we get to see why you had your Artemis blown apart?
You should check out this instead. Eliminates the flex cable and uses a solid drive shaft. I think a better idea, especially on retractions. ua-cam.com/video/lIJQ93Jyou4/v-deo.html
I watched thus type of extruder few days ago. I think this idea is very cool. But, I have question about this method. In this method, torque maintained constantly when the extruder motor will be revolution with constant speed? I think small difference will be exist, when the flexible rod turning each cycle. I think strain will be different by the function of theta. And In this method, force is transfer via to flexible rod. It will have a time constant( like a thermometer time constant). For instance, driver motor act when t=0 and actually transfer to the extruder at t>0. it will be neglisibly small??
hey man i love your videos! you have shown me so much and i cant thank you enough. i was wondering what your thoughts on the anycubic chiron is. i love mind and it has a huge build volume. have you used it? if so what are your thought and do you have any tips for better prints on it. thank you for your time and your great videos.
3DPN,,, Would you say that this is a must for replacing the Boden system on say a CR10S Pro to give it a better more consistent print? Also, are you running this on any of your printers now?
I don't think it's a must, but it's a neat addition. For the CR10s Pro, if you're looking to change and upgrade, look at the Bondtech add on for it. I don't have the Nimble on anything yet.
@@3DPrintingNerd Wow ok I looked at it it would be a great thing to try on one of my printers. I have ordered several to get back started up again. I think it is better because of the 2 feed wheels in place of one it will make stripping out the filament less possible ans induce more force onto the hot-ends keeping a constant flow rate. Great stuff here. Thank you
was the Protopasta filament you used flexible? seemed a little rigid to me... I'd love to see this in action with ninjaflex or some other flexible filament.
hmmm makes me think, why not use a small rc brushless outruner geared down on the extruder, plenty of power and rpm to go around and a encoder to know the position. Odrive software and we can get somewhere
At 30:1, how long does the drive 'cable' cover/tube last? I see lots of wear in the future. That's a LOT of twisty twisty. (But I'm still sold and plan on buying)
I love the idea and implementation. My only query would be, how much backlash/slop is there in the flexible drive? In my experience there is always some give when changing rotational direction (for retraction), is your flex drive made to reduce this?
Curious... In terms of print speed, is it really that big a deal to put a drive motor on the hotend? I mean, the Makerbot 2X I use at work has two motors and two hotends. And it still prints pretty good quality at 90 mm/s. That's ABS too!
Just asking on this video as it's the lastest at the time but I had a question, what colour filament do you think would be the best for prototyping parts? Currently I have some black and green (my dad got the green I think out of novelty I'm not sure) but with the black it's harder to see the finer detail compared to the green, is there a different colour you would suggest (I've only tried pla as well)
Now I'm curious about the gains... can you do a comparison between printing with this and without this on the ender3 pro? I have one of those, so now I'm wondering how much better/faster my prints could be with this awesome device! =p

This should be licensed to Anycubic for their Chiron, would make a difficult filament loading process much easier ? Great Vid as usual
There's going to be some serious flex and slop in that drive cable. Getting the tuning right is gotta be interesting.

It appears that you can change out filament to a different color very quickly. How would this one compare to your normal extruder for purging. Currently having to have a purge block. Can this be eliminated.. that would be awesome or even timed in the g-code. Thanks
I would call it a "Flexi-drive" system. It's using the same tech as a Dremel Flex-Shaft, so yeah.
Yeah, but that's probably trademarked.
They could use a similar name but differentiate it as being a 3D printer product.
Perhaps..hmm.. Flex3drive? Catchy.
@@saldot79 haha yep Flex3drive...
When I saw this video come up I thought for sure it was you putting this on you’re Artemis! When do we get to see why you had your Artemis blown apart?
We'll surely be sending Joel one when we have stock again.. with all of the bits too! :)
This on a coreXY like a railcore will print fast as fudge
You should check out this instead. Eliminates the flex cable and uses a solid drive shaft. I think a better idea, especially on retractions.

Super cool! Now stick it on a prusa!
I'm loving seeing Aussies getting recognised around the world
There was equal if not more design input from Lykle as well (he's Dutch)
I watched thus type of extruder few days ago. I think this idea is very cool.
But, I have question about this method. In this method, torque maintained constantly when the extruder motor will be revolution with constant speed?
I think small difference will be exist, when the flexible rod turning each cycle. I think strain will be different by the function of theta.
And In this method, force is transfer via to flexible rod.
It will have a time constant( like a thermometer time constant).
For instance, driver motor act when t=0 and actually transfer to the extruder at t>0. it will be neglisibly small??
There's a worm gear on the end.
hey man i love your videos! you have shown me so much and i cant thank you enough. i was wondering what your thoughts on the anycubic chiron is. i love mind and it has a huge build volume. have you used it? if so what are your thought and do you have any tips for better prints on it. thank you for your time and your great videos.
3DPN,,, Would you say that this is a must for replacing the Boden system on say a CR10S Pro to give it a better more consistent print? Also, are you running this on any of your printers now?
I don't think it's a must, but it's a neat addition. For the CR10s Pro, if you're looking to change and upgrade, look at the Bondtech add on for it. I don't have the Nimble on anything yet.
@@3DPrintingNerd Wow ok I looked at it it would be a great thing to try on one of my printers. I have ordered several to get back started up again. I think it is better because of the 2 feed wheels in place of one it will make stripping out the filament less possible ans induce more force onto the hot-ends keeping a constant flow rate. Great stuff here. Thank you
I got one at MRFF and I love it !!!
That wire looks just like the ones used in bike speedometers back in the days.
was the Protopasta filament you used flexible? seemed a little rigid to me... I'd love to see this in action with ninjaflex or some other flexible filament.
the blue filament they used for the pokemon was just normal pla i think
I have one on my tevo little monster. I love it. Did they have the water cooled heat brake there?
Um... I don't remember. He had it at MRRF for sure.
hmmm makes me think, why not use a small rc brushless outruner geared down on the extruder, plenty of power and rpm to go around and a encoder to know the position. Odrive software and we can get somewhere
JOEL !
On the table there was a can of Rockstar Pineapple Zero. I cant find that anywhere, whered you get it :P ?
I expected to find a purchase link or something, did I miss it or is it not in the description?
idiot me didn't watch the entire video nevermind me
At 30:1, how long does the drive 'cable' cover/tube last? I see lots of wear in the future. That's a LOT of twisty twisty. (But I'm still sold and plan on buying)
I love the idea and implementation. My only query would be, how much backlash/slop is there in the flexible drive? In my experience there is always some give when changing rotational direction (for retraction), is your flex drive made to reduce this?
The nimble has a 30:1 gear reduction, so any backlash is reduced by that factor. Brian uses less than 1 mm retraction when printing.
@@LykleSchepers Ah! Of course it does, I forgot to factor that in. Thank you.
i wonder how big is the backlash with the rotary flexible shaft.
My concern is how much torque is lost in the flexible. So... could tuning be an issue with a drive like this?
Wish I could afford this technology I do mixed media art and I need a 8 inch skeleton this tech is amazing tfs
100 for a mechanical speedometer drive? Are they grazy?
I'm not saying this is cheap at all but low quantity production products are always really expensive.
Go ahead and make one and sell it for less, I'll wait.
Would love to see one for Prusa MK3s....
Seems like a nice option vs Bondtech setup ^^
Couple of mosquito hotend = sex :D
Curious... In terms of print speed, is it really that big a deal to put a drive motor on the hotend? I mean, the Makerbot 2X I use at work has two motors and two hotends. And it still prints pretty good quality at 90 mm/s. That's ABS too!
Depends on the design of the printer. Printers designed with the motor at the extruder are sturdier then one without it.
Just asking on this video as it's the lastest at the time but I had a question, what colour filament do you think would be the best for prototyping parts? Currently I have some black and green (my dad got the green I think out of novelty I'm not sure) but with the black it's harder to see the finer detail compared to the green, is there a different colour you would suggest (I've only tried pla as well)
Now I'm curious about the gains... can you do a comparison between printing with this and without this on the ender3 pro?
I have one of those, so now I'm wondering how much better/faster my prints could be with this awesome device! =p
I love the concept but there is no way I can justify spending £100 to put this on an £140 ender3
Gareth Martin I hadn’t thought of that. Cheers
i absolutely love my 4 nimbles
thanks Mitch! we're happy to have you as a happy customer!
