Multi-Material 3D Printed Robot Dog Feet with the Lulzbot TAZ Pro
HTML-код
- Опубликовано: 3 окт 2019
- I'm using the Lulzbot TAZ Pro to make hybrid multi-material prints for my robot test dog's feet. This allows me to combine and vary the infill of rigid and flexible materials in one print so get different properties for prosthetic or robotic parts.
I'm using Ninjaflex in Sapphire Blue, and PA-CF from Colorfabb in these prints. This specific video is not sponsored, but I am grateful to Lulzbot for their historic and ongoing support for my RUclips channel.

③ XROBOTS
Former toy designer, current RUclips maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and not-so-useful inventions, designs and maker advice. Iron Man is my go-to cosplay, and 3D printing can solve most issues - broken bolts, missing parts, world hunger, you name it.

④ MUSIC AND SFX
The majority of the music and SFX used in my videos is from Epidemic Sound share.epidemics...
Glad you’re focusing on Open Dog again. That’s the project I’m most interested in. Can’t wait to see it walk.
One other thing I learned a while back....
Dampening - to make wet
Damping - to remove vibration
Please dont dampen the springs, they may rust :)
14 years you’ve been making RUclips vids glad I joined early congrats on 1 mil well deserved 🎉
I know that people like to tear in at Lulzbot for being expensive, but been using their products for a really long time * and I've never had a reason to not like lulzbot machines. They're turn key printers that requires very little front end tuning and they consistently produce great quality prints that are accurate and strong (when designed properly).
*[9 mini's and 6 Taz 6's at my university makerspace, (all of which have been running nearly 24/7 for the past 3 academic years with only 2 mechanical/maintenance related issues) and a personal mini2 for a year.]
ThatOtherAndrew same here, have 8000 hours on my original mini and so far had to replace one wire and 1 printed part.
The 3D printer market has a whole lot of people who look at the specs, and price and assume all printers are equally reliable, and are absurdly pleased with themselves for being so analytical. These are the so-called tourists, who don't really know how to buy equipment to run a business or to support product development. They just fool around printing parts off Thingiverse for a while before finding something else to amuse themselves.
I used to be interested in robotics, but then I met you
Those prototypes look so cute.
I see these listed online for the lulzbot dual extruder for $5k. It literally comes with 3D printed parts on it. At that price point it better come with all plastic injected molded parts.You could legit get a creality printer and make one of these by modifying it for couple hundred dollars.
You're so cool, James- I love folks who are so supremely motivated and smart!
Surprising how many 3D printed parts it uses for a fairly high end machine.
I was also very surprised. For a $5k machine I would have expected mold injected plastic at least.
Not to mention the poor quality on the printed pieces. At 2:26 you can see two identical pieces where one was printed poorly
Why is that a bad thing? Using 3D printed parts makes it possible to innovate much faster.
@@MisterMakerNL 3D printed parts tend to split along the layer lines when they are under stress. So you may find that you have to reprint parts for your expensive 3d printer. Which just doesn't sound right
@@MisterMakerNL They can innovate fast internally using 3D printed parts, but when you ship a final $5k product, you order injected ones (stronger, better tolerances, heat tolerant)
Love my taz 6 and mini. Kinda jealous the pro plays elevator music every time it prints, not gunna lie
Don't be ... is not worth the 5k... expected much more professional machine for the price and now they don't give any support for costumers
If a robotics engineer uses Lulzbot to 3D print robot parts, and they meet his engineering requirements for build quality and tolerancing, then that's good enough for me. Remember that the US military and NASA have all used Lulzbot printers at one time or another. These are among the most demanding users of 3D printers and if Lulzbot was chosen by them, that should tell you something.
Around 3:30 in the video the whole carriage seems to tilt around the Y axis when it is wiping the nozzles. Is that right? Seems like it should be more rigid.
I know nothing about this printer, but if I had to guess Lulz Bot might have added a rotational axis to make the head tilt allowing them to switch between the two nozzles, allowing you to print with one and leave extra clearance for the other, unlike normal printers which just have them in plane. This could be a useful feature to help prevent artifacting on multimaterial prints.
Look around 4:07, the tool actually interferes with lower part of the carriage and makes an audible click. Terrible clearance.
@@coulombicdistortion1814 Isn't that the whole point of raising the other nozzle up, though? It couldn't possible be intended to rotate like that. There's no way it could do that consistently enough to remain calibrated.
I was wondering about that too, but apparently, it doesn't seem to affect the final product- the final print turned out just fine.
The Taz 6 dies this as well, the carriage wiggles a bit when wiping, when printing there is no drag on the nossle so it doesn't move.
I swear to God, soon I'm going to write a fairy tail entitled: "James Bruton and his million sensors". :-)
I think James is taking salsa dance classes.
It’s a good lookin high quality printer for sure, but 5 grand for it? At that price point I would get a raise3d machine, which has a few more features (like a sealed chamber with hepa filter) and higher quality parts
Very well done
Some very nice robot dog training shoes!
Somehow I doubt the people who downvoted it actually watched the video
The down-voters are low IQ idiots.
nice video james!
That's an Open Puppy! :o
He's printing ningaflex! (envy)
looks good. That printer isn't quite in my budget, but I can enjoy watching you build the OpenDog 2.0 now
Nice work i learn new things every time i watch one if ur videos
Great Job James 👍
6:00 - "Hey, my coffee table is getting away!!"
Why does it look like the carriage cable chain lays on the bed when in front right position?
Wow! That's the Lamborghini of 3D printers. Probably costs a fortune!
Cool was also seeing that Korg multitimbral device as part of the backdrop for your Area51.5 laboratory, you smarter brother from a different mother.
Geezus that thing is $5k (USD)!!!
If you want multi color prints, the Prusa is way better and 1/5 the price at most
We know its free for him. 5k is way too much a kit look printer and has printed parts too lol
you need to crank those travel moves to 300mm/s and acceleration to around 2000, also faster print moves, it can handle it
and if there's a way, you should also see how you can make that change servo go faster
You can't print that fast in Ninjaflex
Would you / have you tried to get in contact with boston dynamics and have a tour of their facility? It would be really cool to watch and you'd fit right in
Yes, but then again, he's doing very well without them.
@@LiLi-or2gm oh I know im not saying ask for advice or help I just think it would be a cool experience and If anyone deserves to go its James
Looks awesome!
The cable chain touching the print bed had me worried for a bit, but that seems to have been resolved.
Interesting printer. I like the Auto leveling and dual extruder design, but $5K for a relatively small build area, no lead screws on the Z axis, and it looks like some 3D printed parts, hmm.
The build area is almost 12"x12" thats pretty big. All parts that can be 3d printed are, its part of its open source roots and allows the user to replaceand or customise the prunters parts. The belt driven z axis is a new improvement over the lead screws from the taz 6, no z wobble, no binding, and much faster
nice
Brilliant! Can you do the dancing robot with smaller movements so it can keeper a tighter beat? like move the elbow and inch on the quarter beats?
Wait, this thing can clean its own nozzles??
My God, they are getting smarter...
Also, when you mentioned a controller being 32 bit, I honestly thought you were going to say that the previous version was 16 bit...but nope!
The mini 2 also cleans/wipes it's nozzle
Why would you need a purge block if you have two extruders?
I was wondering that, too 🤔
Some filament can ooze out when one extruder is idle.
Why does the cable chain hit the print bed?
Doesn't that destroy prints?
Wish they would injection mould the stepper housings. This just annoys me.
It does seem like the achilles heel of the o-drive is poor holding torque. Such a cool motor driver (ROS support coming soon!?) that is so good at a bunch of stuff but if your project needs holding torque... I don't have one so if I'm wrong I'd like to be corrected.
I think it's just the motors are undersized!
Are you paid by lulzbot or got sponsored the printer? That's a not cheap product..
Great video. Mahalo for sharing! : )
Why don't low end printers come with USB ports? Lots of cheap ARM microcontrollers have USB host controllers and the HAL libraries make them basically a drop-in replacement for SD cards.
I was very dissatisfied with my purchase, many parts were 3d printed at a low res and the poor design cause the extruder to weld itself to the mount with filament on the 2nd print, smh, so i sent it back. Also for 5k there was no network connection.
The cable chain drags on the bed?
Hi James,
Wonder if you could give me some help...
Got a Taz Pro about october 2019 for educational purpose and after three prints had a big issue until now... and cant get any support from Lulzbot.
Have you ever got a issue with your printer after printing flexible material?
After heating the heads the printer just shuts down and restart again. Got (mintemp) error on gcode.
Cant get any filament through head 1 so wonder if the nozzle might be blocked and is causing this error.
Hope you can read this any help will be much appreciated.
Now there is something interresting herr. I adsume your design is inspired by spot mini. Now that is using i beleve either pneumatic cylinders or spring loaded electric actuators mounted to handle the movement of the leg joint. Can you tell us why you choose to do gears instead considering you want dampening? ...
Spot mini is totally electric
@@jamesbruton so the lower joint must be driven by actuators then?
Did that cable chain drag on the print bed!
What sensors are you planning to put on an OpenDog robot, once it can walk reliably by its own power?
Are you going to use topology optimisation for the design of the feet?
$5000 dollar printer. Business must be good!
I have a question: How much did the materials cost for each of those feet? I'm trying to estimate how much it would cost to do several projects in material alone...
first good, Taz pro go though :D does it have a Duet card ?
So 40 hours to print 1 , what is the power consumption of the printer?
What a printer
Can't believe lulzbot is still using hot end conductivity for leveling. keeping the nozzles clean enough for that is a massive pain in the ass, at least on my gen 1 mini. The prusu use of magnetism is WAY better. Also I am always annoyed that Lulzbot charges SUPER high prices for their systems and gives you 3d printed parts that are not nearly as good as if they were molded.
Maybe you can make some from Terminator
Will these updates make their way into OpenDog or have you moved on from OpenDog?
Yes! this is a fork in the development, but It already seems easier to make it work. Once I've sorted out the actual stability control then I'm going to attempt to simulate the reactions in openDog's rigid actuators.
The cinematic model of your dog will become really complicated, because the length of the legs depends on the angle between the leg and the floor.
kinematic*
Is it still noisy like all the other lulzbot machines?
It's more like the Lulzbot Mini2
James Bruton I have the tax 5 and it’s loud
Perfect printer ever 👍
can you please share the f3d file from fusion 360
Good idea why not use a flex sensor ?
An UnaccountableScience many ways to skin a cat :)
You are so coool man ;)
Да, чувак ты крутой )
Ты тоже )
Over £5,500 for this printer lol not sure where they get that pricing from, i could buy over 20 of the printers i get that print of similar quality
two words johnny five (-;
Two more. Is alive.
@@apbosh1 he started to print a johnny five some time ago...I would love to see that finished
For a 5k$ price tag, I expect not one part on the 3d printer be 3d printed. That is BS.
That looks like a very nice printer. But that thing has so many printed parts for a printer of that price range!
$5000???
that print was ridiculously slow
Phizicks welcome to ninjaflex. You could print cheetahflex or armadillo but the durometer is higher but you can print faster.
Man 5k for that printer!? It's way overpriced for what it does
whose here in the first half hour? like
Take a breath bro...In the time of nonsense talking , unsubscribe
Too many 3d printed parts on it, screams cheaply made to me.
