- A 3-d printed 2-stage axial turbine powered by a standard vacuum cleaner.
It spins at 60,000 rpm, sounds like a 747 taking off, and sucks up its own dust! I just made this for myself, if you want one you'll have to make it!.

This is one of the coolest, most practical things I've seen done with a 3D printer :o
This is an incredibly good idea! Considering the cost of buying the rotary tool alone makes it worth it, but even moreso considering that this one will keep a workshop much, much cleaner, and the vac can be used on its own! Great job, and I look forward to the progress!
Thanks for that. The idea started as a way to make a turbine on my printer, the potential usefulness came later!
I'm new to Dremels, but this thing has been great. czcams.com/users/postUgkxfPgcZ5_Cl0HDUKkMJAKde11YKQZVgMoR The variable speed is awesome and the cordless aspect makes it so easy to work with. I am constantly finding uses for it that make tasks easier. Recently I put in a new deadbolt on one of our doors. I knew I had to enlarge the hold where the deadbolt goes into the door frame. At first I thought I would have to get a big router and figure out how to use it for that, but then I rermembered we have the dremel. I was able to enlarge the hole almost as easy as if I was drawing with a pen. It's also great for grinding our dog's nails done and so many other household tasks.
When I first ran it I thought the same. I was reading QF 32 at the time (great book) and was aware of the dangers of exploding turbines. Actually, the PLA I used seems to hold together OK, so a production version with metal or injection moulded plastic rotors should be fine.
The bearings are a challenge, partly because the 60,000 rpm is too fast, and because the plastic cannot conduct the heat away. Laser cut metal rotors would help, and the front bearing needs a good shield for dust protection.
That is some crazy rotary tool !!! brilliant.
I really like the concept and i will definitely be making one of these, when i get my printer! It will allow me to "dirty" stuff in an office space (my appartment). :D
I think of making a velocity stack on it though, so it will suck dust from a larger area, but still have high velocity at the fans.
I would buy one. The choice is yours.
Well done,very useful tool and well made too!
fantastic! i'm so willing to try this myself since I got a solidoodle this month.
Genius!! I absolutely need one if these at my shop/garage lol! I know what my next project will be
I hope you patented it. This was genius!
Very clever idea. I like the fact that you bring the heatsource from the normal moter away from the hand. It is only a plus that it also takes the dust. Great work. If it is possible i would like a sample for my workshop.
Awesome!!
That would be even better if you could put a flywheel in there to give it a bit of momentum...
Awesome, will try that one as first thing when I get a 3D printer!
This is just amazing, I am thinking of the applications this could be put to. Maybe a complete workshop run on a few vacuum cleaners
I am Seriously Impressed. I read your statement on Thingiverse.
Designing a Product?
You game at least 7 just from watching the video. I definitely got some work ahead of me.
I machined the main shaft on a lathe, it is not a standard item. The nut and collet are Dremel, the bearings common industrial, and the plastic parts were 3-d printed.
COOL. looks like a nice addition for my tool box. i will defiantly be making one. my girlfriend works at a veterinarian and they use a dremel to do dogs nails, this seems like a much better option for light work like that.
Very cool, I would buy that.
Wow, I had no idea that orange 3D printed turbine could do 60k rpm without flying to bits. Great idea.
Thanks for your comments, but I only made one for myself, and have no plans for commercial production.
c'mon. C'mooooon. C'maaaawwwwnnnn. We don't all have 3d printers. nice work though, if you change your mind i'll be first in line
You have to get a patent on this tool its so Nice
+Finn Stevens Dremel grabbed up this concept.
yeah and Dremel made a complete balls up of it, this is way better.
Seems to have more power than a Dremel 3000.
Very nice work!
Thank you for share!
and it won't fail as dremel did after few years
@@RoadT123 And if it happens, you just "print" another one.
This would be a Godsend for bone cavers. Bone dust can make one very sick, and high torque/high vibration devices can create microscopic cracks in the piece that can comprise its structure (ie; falls into 2 pieces when you are polishing it). This could save a bone carvers lungs/life.
A production version should have rotors made of thin laser-cut steel which are twisted into shape, so the whole shaft would keep cool.
All I see is little metal bits flying directly into the bearings, making this thing a spinning explosion of plastic parts when those bearings finally fail.
I know it is awesome, but I just can't help seeing it like that.
!
that's neat
where can i get the shaft?
@Richard Macfarlane Yep rpm is awesome but torque must be very low. A cutting speed caparison whit that dremel wold be great.
can you use the shaft and bearings from a Dremel flexible shaft kit?
I have not tested it much, scared of the PLA which softens easily with heat. Composite cutting with the discs worked better than my Dremel, with the higher speed, and if the disc jams, the lower inertia and stall torque saves the disc where the Dremel smashes it.
The little grinder worked about the same.
Proper torque testing and rotor optimisation would be good.
Very impressive. Don't the plastic turbine parts get deteriorated by the metal dust?
Can we use it on a low end cnc to cut wood? Or a corded drill is better?
That could be used as a spindle for milling..! :D
It will be quieter if each disc has a different number of blades. Like 14 13 12 11 instead of 12 12 12 12. What you made is basically a siren.
you could probably design a smaller one that can fit inside the vaccume tube and has an outer cap to keep it from getting sucked into the vac. that way worst case scenario if it does burst its inside the vaccume tube (you can buy shop vac tubes that are steel i believe) and it won't explode all over you. (though all of the parts are now inside the vaccume)
Wow! This is extremely clever! Would you consider selling the metal parts?
Fanyastic.
That's epic, well done , I'll be printing one and doing some experimenting. Wouldn't using less suction cause it to spin slower ? 60k is a bit brutal lol
Oh, so you fabbed the metal parts as well? If so, would you be so kind as to list or make available the specs of the metal parts as well? Would be greatly appreciate if you could.
Nice dude! Try making one with the ball bearing from a garret turbo or the ceramic ones from turbonetics, those spin up to 100k
Have you made them yet?
This is a 1000Watt grinder!
Yes, this would be a good Kickstarter project, but not for me as I only did this for fun. Somebody else can make it happen if they want!
What is the metal part from?
hi i am really interested in this turbine rotary tool i have already downloaded it and will be printing it soon but i just want to know that where could i get the bearings and the rotor shaft and other parts so that it could be a functional and complete device thanks allot mate and please could you send me a reply
wow my dremel broke and i see this and i have a small and more portable shop vac i thank you sir
where i can bay it?
Nice! is it on thingiverse?
But doesn't to vacuum pull way more current than a normal brushed rotary tool
+hhguitars xD
3000W vs 150W
@@juliandahl1999 No need to run a shop vac at the same time with this though ;-)
how do i made one for me?
kickstarter please!
It's thing 76369 on thingiverse. (youtube won't let me post links)
anyone know whaere i can get that shaft?
...that's what she said
where do i buy those spacers and shaft, anyone?
they were milled on CNC
make the 3d printed parts fit the vitamins you have available get. is my opensouce philosophy. :) i had mine made by a friend that is polymechanic
highly energy inefficient, other than that it's a neat toy.
Kickstart this. I hate nothing more than the debris that comes from using the rotary bit.
Kickstart this, plz, and TAKE MY MONEY!!!
Funny that Dremel took this idea and seem to have made it crap with the dremel vrt1-1/5 which looks totally gutless compared to yours.
Amazing if the Dremel one is not so good, I only spent a few days making the first one, they have had years to develop it. But mine was maybe too fast at 65,000 rpm, maybe they slowed it down for safety. But they could have changed the design for lower speed with more torque to keep the same power. It would need to be a slightly bigger diameter, less pitch on the blades, but maybe 4 or 5 stages instead of only 2.
Anyway I'm happy that Dremel produced a product form my idea, but they should have improved it!
+Richard Macfarlane It's a brilliant idea.
