Happy printing!
Hi, did you try to bend AISI 304 for example? Would it survive? Thanks
Hi. I havent done any stainless but it all comes down to thickness. Im sure you cant do 6mm but 2-3 ?
Maybe ill try it some day, let me know if you do :)
@@randomrouting Hi, just for update. I did a test with the V50 version and Stainless 3mm. bends without a problem, S355 4mm. bends without a problem. One more great benefit with this tool is that when using brushed stainless or anything that you don´t want lower tool marks on the products, that is the way to go👌👍
Great job, great success !
@@edwardeesti That amazing! Thanks for testing and sharing!
I love those tools. We do not use them much. Super expensive, awesome you can make them.
this metal torturer has a Prusa on his workbench. Don't forget it.
I like your energy and enthusiasm! I'm printing some dies right now for a project and had some doubts about how well PLA would work, but seeing something as impressive as this done with the same material is very encouraging.
Nice innovation. Thanks for sharing this idea. I continue to be amazed at how useful 3D printed plastic parts can be.
Great job! Those tools are so expensive so this is a nice alternative to keep in mind for jobs that can't have tooling marks!
Indeed! And whenever you need to bend really really close to a hole or edge.👍👍
I love this stuff! can't wait to make some of my own, thanks for sharing the video!
Man, that's awesome!
Nice one, Keep up the good work! Love to see more videos certainly about the press brakes but also love to see some about your company.
Thanks, Will do 👍
you are creative . Frankly, I needed this video . Thank you so much
👍❤
Nice thing ))) when we bought brake, exactly must have it!
Nice work making this tool, I've printed some TPU inserts for our brake but haven't messed with making rigid tooling yet. We do have some Rolla-V tooling, it's impressive that you got this to work.
I'd love to see how this printed version functions in more of the specific use cases that this type of die is sometimes used for. This seems like it works well for keeping the tooling from marring the workpiece but will it work in the other situations that the more industrial versions of this tooling is good for.
I've used Rolla-V tooling for a few different reasons:
1- To help form perforated sheet accurately. In normal tooling the bend will 'jump' to the path of least resistance when forming perforated sheet. The back pressure created by the springs in Rolla-V tools basically clamp the material in place before the bend starts so it cant slip into the path of least resistance.
2- To help prevent 'pooching' when your bend line is not perpendicular to the edge of the sheet(like a miter at the end of a bend)
3- To help form very short flanges. In the tooling that I use(The smallest version available of Rolla-V) we can get a .125" ID bend on 16g steel.
I love seeing printed tooling for press brakes, keep up the good work!
Hey. Yes these would be good for all those reasons. Ivve done tons and tons of parts with them and short flanges and/or support around the bendline is one of the big benefits. Most likly wont do AS SHORT flanges as the rolla-v but probably not far from it.
Ive got some older footage and I have recently designed one for the 40mm V-die for the Amada so Ill post a vid on that at some point. 👍
Very very nice
hey thanks so much... we were just about to design one of those, and your design is a great reference. cheers
👍 Dont forget some type of lubrication. I forgot to mention it in the video but I use dry ptfe in a spray can. works great.
@@randomrouting thank you so much for the tip, when our version is done, will post a video reply
Awesome content, thank you! I tried printing the 50 sized this am - all went well except the spring clips on the 2 moving pieces. Any tips for helping with that? I printed vertical/similar to how you have the 35 models sized, and did not use support (didn't look like you did on those 35's shown in the video).
100% infil, printing with PLA on a X1 carbon.
Thanks for sharing. Was just looking at the step files. Curious why the radii on the roller dies are 10.816mm?
Not sure. It was probably a nice even number staring off. They went trough quite a few iterations where some times I rescaled the parts, probably by some procentage. Every other size is a derivative of which ever was first so thats probably why both models have the same radii.
nice!!!!!
👍❤
This is a great little concept. Some questions on the 50mm print. 1) which orientation is the main body on the 3D printer. It seems the tubes in the main body for the spring will need support material which after doing the first print is impossible to get out. Also, the site you linked to at Thingiverse for the spring doesnt appear valid. Any sources in the US for the springs. Thanks
The 3d file for the 50 (on thingyverse) is a "print stack" that has two sets bundled and they print vertically. There are modeled supports of the far ends of the "tunnel" that easily snap off. Thats all thats needed.
The link for the springs seems to work when i try it. I dont have any knowlegde of suppliers in the US.
Looks like Rolla-V. Try to bend small border (flange) on this dies
hello this could be a big help with some parts that we form , I just wanted to test these out on my printer ( new at 3d printing) I started with the size 50 model
and I'm a 1/4 way threw the print and I just don't see how it will pivot with it all being attached, I see where the size 35 is printed separate and that shouldn't be a problem but I'm going to have to stop this print. am I MISSING SOMETHING?
Yes I mention this in the description on grabcad and thingiverse.
"Size 35 3d file is a "print stack", as i printed them with tabs ect for stability and printing two complete sets at a time. 3dmodelled supports.
Size 50 is the 3d model, print them as you like."
Hope you get it sorted. 👍
Amazing work, what is the purpose of this rolling style tooling rather and a normal V and punch?
Able to bend super short flanges, no marring, no deformation of slots/holes ect. Its pretty great when you need it.
You could search for "wingbend" here on youtube to see the steel version and its benefits.👍
Wow this is so smart, am currently also working at a sheet metal factory designing 3d printed presses and dies. How do you calibrate the ammount of tonnage to press?
Thanks! Like any special die I guess, so it depends on the machine. You could use the distance between the points of rotation as a crude V-size to start off with but you still have to adjust values. On the durma I just did tests and saved the values for each angle/thickness as preset programs, on the Amada I used the pendant to jog down until i got 30,45,90 ect and saved those values in the controller, its then more of an positional control rather than tonnage.
After that you'd just adjust for material like any other die.
Good luck! 🤞😁
@@randomrouting Ah yes I understand at work (internship) I have 2 trumpf 5130's and 1 beyeler. The trumpf machines are CNC whereas the beyeler is programmable by hand. Guess the beyeler is my best option but the trumpf would be very nice for allot of different parts. I already printed a R20 tool and bent 4mm steel which was quite impressive. Still need to find a way to accurately calculate the right values for the different materials. Now everytime I need to make adjustments in degrees for the first part. The factory has small batches of highly complex parts so need to find the best way haha. Thanks allot for your reply, very cool you use Prusa aswell :D
@@TheOomen2012 Prusa ftw ;]
I apologize in advance, I'm new to all this. The die came out amazing and I thank you for the design. Helping out my brothers new business. Can some one please post the link for the spring. I feel stupid cause I can't find it any where. Great design and greatly appreciate your work. Awesome!!!!
Link is at thingyverse (link in the description) but it seems the site doesnt work when u'r browsing from abroad? You could just find something similar locally.
Diameter is 3mm, contracted length is 25mm(including hooks at the ends), max length 85mm.
Force from 0,4 to 4.1N linearly.
You could use pretty much anything even semi close to that, as long as it fits in the holes and 'somewhat' correct length and you should be fine.
Dont forget to use some type of lube for the die tho, i use dry ptfe.
And no need to apologize, we've all done that journey and you have the best bits infront of you!
I owe so much to youtube/internet-community sharing that I could never contribute enough to pay that back.
Good luck with the new business!
That stuff is so cool. Which material did you use to print these?
Prusament PLA 👍👍
@@randomrouting thats even more impressive👍🏻 Nicely done, thank you for the inspiration!
I really need to make/design me a press and try this
Indeed!
wow, nice!!!!! what are your setings???? 100% infill???? how many tons do you use?
pfff i already read the description.... sorry jajajajaja
At 0:41, what is the name/brand of that tool with the 4 sides with different bend diameters? Thanks.
Pretty sure those were from rolleritools. 👍
That impressive have you tried to bend any stainless steel material?
I have not, thin stuff should work fine tho.
what's the point of this die? does it prevent deformation around holes?
Among other benefits yes. If you look at the slots in the 6mm alu at the end and the distance to the bendline, that would look terrible with a traditional die.
Really short flanges are also possible with a die like this. Look at "wingbend" or "rolla-v" on youtube for the steel equivalent, they highlight pretty much everything.
Hi man, how are you? Tell me please, is it possible with this made 1.5mm thickness soft steel corner 90° with 4.0mm front side and 50mm back side, R1.0 die?
Hi. Im great, hope you are aswell.
I think a 4mm flange in 1.5mm steel might be difficult. If you took the size35 and scaled the V size down a bit (distance between the center of rotation) it would probably work.
With the size 35 alot of pressure would be exerted outward horizonally away from the center and thereby possibly pushing the folding pieces out of their position.
What grade aluminum is the 6mm?
This was couple years ago so cant really remember but odds are its 5754.
Wow, I tested and they work well. Could you please design a V40 one?
Glad to hear it! I have been meaning to make a V40 as i need it for the Amada. Unsure when Ill get to it but its on the list 👍
@@randomrouting Hi, how do you use them in a CNC press? Did you requested a rolla-v tool file? I only managed to get them working in an old manual one I have, but I was wondering how to use them with my Gasparini which uses Delem CNC. What I tried always ends in a broke die.
@@alexsanchiz Hi. Sorry i didnt see this comment before. There is no file to import so this needs to be done manually like any specialty die.
Once values are saved then its as quick as any other die.
Anybody got link for springs that’s works?
Seems the site doesnt work when u'r browsing from abroad. Anyways, diameter is 3mm, contracted length is 25mm(including hooks at the ends), max length 85mm.
Force from 0,4 to 4.1N linearly.
How do you like the durma brake?
Its sold and honestly it was a mixed bag. Mostly because of the rep that sold it to me (long story) but also there were some things that werent great. It had a wierd noise when warmed up so the hyraulic pump had to be replaced, Belts on the X-R axis were too tight from the factory and caused alarms. Makes you wonder about the QC.
The controller DT15 was a joke. Its probably fine for super simple stuff but there were plenty of bugs and wierd behavior. Alot of it got fixed with software updates but not all. If you are serious about what you do dont get the DT15.
As a side note, the machine came with DBend (durma licensed metalix mbend) offline software.
HOWEVER, of all the controllers the software supports, durmas own DT15 is the only one that cant show images on the screen. So you have no idea how to orient the part unless you print out the report.
Also running around with usb sticks is not very 2021. It did have network port but not used for connectivity. Go figure.
It did the job tho. It was alot less expensive then the Amada (obviously) so I guess its not all bad. Perhaps it was just a lemon.
Probably wouldnt buy one again tho.
@@randomrouting doesn’t sound like the best experience! Do you know what kind of pump they had on it? We have a durma but with a Delem DA-66T. The Delem DA-66T controller is great to be honest.
@@risedabovetherest Yea the 66T seems way better. The pump was a very generic looking gear pump that you see on pretty much everything. I dont have a model/make unfortunately.
No way! what?

Hi, I'm from Brazil, a tool like this measuring 300mm machined in a machining center costs 4 thousand dollars, I want to print it on a 3D printer like you, the cost would drop to 5 dollars, hehehe. My question is how to assemble the spring, how did you do it? Is there a video showing the assembly of this matrix?
Thank you, your work is very good
Hi. Yes the steel version is very expensive.:)
The 3d printed parts have a tiny hole/slot that the end of the springs hooks into. I used pliers to fiddle them into place.
You can probably come up with a better design for that part that is much easier to assemble.
@@randomrouting Speaking of the resistance part, you used PLA, but if you switch to ABS, we can guarantee greater durability, and what was the printing process like, standing up on the table or lying down? because, depending on the form of printing, the piece becomes more rigid without the need to use 100% infill
@@cristiangama9747 I printed these standing up, there are links in the description to the files and there you can see how the the smaller version is bundled to print two sets at a time.
I never tried ABS, im sure there are benefits and such but this started working to well that I didnt feel a need to continue iterating. Im sure other plastics would have different friction and hardness/deformation springyness so I just keept using PLA. (I use dry ptfe powder in them btw)
Im sure there are many ways to improve on these tho, post a video if you do :)
@@randomrouting When I do this, I'll let you know, I'll study some ways to improve. Thank you for exchanging ideas my friend, a hug from Brazil
cool thingy mabobber..?
I hereby declare that as its official name.😉
Can I get a drawing or a model?
