- 3D printed tools are a cheap and easy way to turn any vise into a mini press brake. In this video I want to share some of my experiences so far.

Due to your request I uploaded the .stl files used in this video to thingiverse: www.thingiverse.com/thing:4063689
do you mind uploading as step parts aswell? so much easier to work with and modify...
Imitation is the sincerest form of flattery. TOT would be proud. Nicely done.
Great idea. This could come handy at some point.
Damn! I saw articles on 3d printed press brake tools, but I never thought of attaching them to my vice. Thank you sir.
Clever... I have a huge vice with a 14" throat and for some reason never thought of this. I even have a welder so I could make these out of steel. You opened up a whole new world for me with this. lol
Imagine creating a decorative enclousure using solder as a decorative seam "weld"? This brings complex shape metal working in reach of the table-top hobbyist!
This should get you close:
Bend radius is ~20% of bottom die width (for v shaped punch).
A 0.625" wide bottom die (using v punch) will have a .125" inside bend radius on most sheet metals.
From each side of the bend, remove one material thickness of length from your overall flat pattern. If you're bending a 1" tall by 2" wide channel piece, you will subtract one material thickness from each "leg", and (for 2" OD) remove two material thicknesses from the center. For 2" ID, don't make any subtractions for the center. The result is 3.748". Add bend lines at .937" and 2.811", and bend.
You will get close. To get closer, remove a material thickness plus the bend radius minus the Cosine of half of the bend times the radius.
R-(Cos(bend angle/2)*R).
Subtract both that number and the material thickness from each side of the bend to get really, really close. Within .005" or so, for most .037"-.078" steels.
So
For a U shaped box channel of 1" tall by 2" wide (outer dimensions) with a bottom die of .625", using a v shaped punch, and .063" thick metal, you would subtract .063", then .125-(Cos(90/2)*.125)=.0366" for .0996" overall after material thickness (simplified to .1") from either side of each bend location.
So you get a flat pattern that is 3.6" wide overall. Then you add bend lines at .9", and 2.7" from one edge. (Four total .1" deductions, two from either side of two bends). Bend that part, and you will be really close to a perfectly bent part that is "1 tall by 2" wide.
The above formula works for any bend radius.
Nice and simple! Love your reference to TOT.
This is a great use of 3D printing for low cost tool making. Very interesting.
Thanks. I've been thinking about testing this for months. Now I already know it will work
Such a good Idea! Congratulations!
people like you are geniuos and make the world a nicer place! Thanks!!!
I would never have thought that 3D printed tools could be strong enough to bend metal. Thank you very much for sharing this.
You can print titanium , nickel and steel alloys so they are pretty strong even stronger than wrought parts of same material the weakness is usually ductility and low fatigue life. But can be improved by carefully controlling manufacturing process parameters and post processing (hip).
Upvoted for reference to Tony, and also for the great proof of concept, now on to CAD modeling for my own versions :p
so simple, but so good. i'm definitely going to do this to my vice.
Ein sehr kreativer Einsatz der 3D-Druck-Technik! Ich bin immer wieder beeindruckt, wenn ich sehe, was die "Werkzeuge" / Bauteile aushalten. Deine Videos sind super produziert - #BigProps! 👍😎👍
The round punch was a fantastic idea!.
Had a thought! On the goose neck plate, since the top surface is rarely if ever going to be in the way of the sheet bend a VERY simple way to significantly increase its strength would be to bolt & glue (or glue & bolt 😁) a suitable thickness (2-3mm?) steel plate to its top surface! (Comments?) Would this also enable a longer higher goose neck.
In addition a piece of angle iron fitted into the V slot would increase strength in that too for thicker material bends.
Instead of a vice, for really tough material ... A hydraulic jack & jig?
So many ideas since I intend making a hydraulic bearing fit/remove jig that would only need the relevant mounting fitments for these tools.
I really like the rounded profile tool too. Great for making rounded top case profiles. The price of instrument and project cases is becoming crazy. Such simple tools mean sheet steel (or aluminium) salvaged from white goods - dish washers (stainless!), Washing machines & tumble dryers (enamelled and galvanised steel), fridges, freezers, fridge freezers all have many large flat panels, all simply removed (& further cut to size) with a cutting disk angle angle grinder! If you're into building electronics and need suitable enclosures ... Say no more!
Bravo! Loved you idea!
This video was very useful and informative for me. thank you very much.
Clever! We posted this one on our homemade tools forum.
Great video. Never thought of this.
Superb, as stated great for small work. Nice new toy ☺️
this is brilliant, thank you!
This is a tool that will come in quite handy!
INSPIRING! Thank you!
Thanks for share, its a great solutions low coast
You just won my sub from that TOT reference
Wonderfull idea, thanks!
Totaly will try it but i dont have printer . I consider buying one of theese but dont know what to choose Kossel , tarantula pro , ender 3 or ender 5
great tutorial. I was not aware that PETG was that stron. Thanks :-)
Great job!
Il fallait tenter bravo! intéressant pour les petits carters, merci!
Rule of thumb for steel:
Minimum die opening is 8x material thickness (you may want more with printed tools)
Bend radius for mild steel is 0.16x die opening
Bend radius for stainless is 0.2x die opening
I wonder if you could attach some steel stock of some sort to extend the length of your vice faces and thus be able to bend longer pieces without all the back and forth. Of course, you'd need some hefty stuff to minimize deflection...
GREAT VIDEO!
TO RECAP:
5 perimeters
0.8 mm nozzle
80% infill
0.2 mm height
material : PLA or PETG
The other chucks need to be in a 3 m radius from the lathe for the teleport quick change to work. Didn't you read the manual?
:)
Perfekt work 👍👍👍👍👍
Thank you for sharing.
That's a great idea.
If there are high surface finish requirements when press brake/edge bending, the Swedish product Tribotextil™ can be applied in the pressing/bending tool and mechanically protect the sheet metal from scratches and other damages. Tribotextil™ is an extremely thin and very strong textile that in this process replaces lubricants in the tool and also protects the stamping tools from wear and coatings.
Good work!!! We also have rich experience in sheet metal fab, we are a strong manufacturer in China, with high quality and competitive price.
That was cool👍
This is truly a neat and practical idea! Gave you a Like over at Thingi.
Wow! Perfect !
Has anyone tried with minimal infill, leaving one side completely open and filling the 3D printed hollow with fine concrete?
I'm looking to bend a sheet of 2mm thick Aluminium, will this do the job or will it break, because to my knowledge Aluminium breaks when bent too much. Thank you so much for the video and the project
thats pretty awesome
great info
Printed tools are not the revolution but we liked the idea about the vise. Great job, really, very interesting and educative video.
Thank you for the wonderful new idea are these available on thingy or my tiny or custom made? Thanks.

How do you make the bend at the right position?
outstanding
Now do a video on mounting a motor to your vice 😀
Awesome job my german friend. Greetings from Albania
great, thank you
Very well 👏👏👏👏👍
Cool!
Frohe weinachten und en glückliches neues jahr. könnte Ich solch einsett kaufen danke schön
Wunderbar!
These are awesome Would it be possible to get the Stl from you?

Interesting but I will now attempt the same thing using angle iron welded to a flat bar, so I can bend thicker plate.. on my VICE.
good

ToTters and the Time Machine
А где можно купить такие насадки? Может кто знает,подскажите
👍👍👍👍👍
Is it just me or does the printed punch and die parts look underextruded af?
Yeah, but that's just the bottom layer which suffered from a bad print bed calibration. The rest of the part looks a lot better, check out 0:55 for example ;).
@@leonbrauns jo, stimmt... In that case it doesn't matter... Souldnt affect overall stiffness and rigidity. Worse thing that can happen is maybe longterm the underextrudeds side edge rolling over slightly. Then again it doesn't matter if you do several passes over the length of the bend anyways
cool video
👍💪🕊
Well I goose it's broken, but time traveling stuff is finicky better ask the master ToT how to work it.
Just watched Blondihacks. Apparently you'll need ToTOS installed on your lathe to access the Chronology functions. IIRC you'll need to flash your spindle to the latest etherware version before install. Also; make sure you have your tools properly honed in, or you won't be able to break the closed time-like loops and they'll make a rats-nest of potential timelines.
Hi there where can i get the STL files

Can I buy the STL file?

Прикольно!
ПРИКОЛЬНО
Come on put an electronic screw driver to actuate the vice! ;)
You will break your vice screw and not
Because they are not designed to work as bending press
Why are your prints severely underextruded?
Great idea! But don't need an 8 minute video. Just one photo will do. 😊😊😊😊😊
Thank you very much.
