Bending Steel With Plastic Tools
I've been wondering if 3D printed tools could possibly bend steel. It seemed possible unlikely. I designed and printed several tools which are used on a hydraulic press to bend and form steel sheet metal. This particular tool could be made by CNC machining the tools from metal but 3D printing it is much faster and easier.
These videos usually take a ton of work and a lot of money in tools and materials. I've made a patreon if you're interested in supporting the creation of these projects:
If you're interested here's some of the tools that I use in this video:

    Quick note, the slot for the blade needs to be larger enough to see what you're working on easily. =) Oh, your hydraulic press sounds like a humpback whale when you raise it.

    Easier solution to the first draft - You have a plasma torch...we saw you use it... use it twice - Bend the form with just the two side holes, then place the part under the plasma cutter and cut the large hole. Problem solved!

    i have no experience with sla printing but a fair amount in fdm. Is sla typically as strong as FDM? I remember when i first got into 3d printing a few years back i thought pfffft this plastic stuff has gotta be weak but to my surprise even the cheap PLA stuff is pretty dang strong.

    Quick audio suggestion: I've noticed in many of your videos that your compressor successfully cuts in whenever you drop a part on the bench to avoid an overly loud bang, however the release time is quite long so your voice is too soft for a moment after each time you do this. If you reduce the release time by 100-200 ms it should fix this. Additionally prepend a high pass filter with a well chosen low cutoff frequency before the compressor, and you will have less power in the bang of a dropped part which will help keep that out of your final audio without removing too many low frequency harmonics from your voice or the other interesting sound you want to keep in videos like these.

  • chromosundrift

    This may be a naive question but is there any advantage to considering the temperature of the piece being pressed? Is it possible to "warm" it to improve bendability?

  • Arthur Williams
    Arthur Williams

    Word of advice. I see your hands are full of cuts. There are these chainmail gloves you can buy cheaply on amazon that commercial butchers use to protect against cuts. They work really well when handling sheet metal too. Video is top notch, keep it up!

    • Arthur Williams

      I say cheaply, because that glove will more than pay for itself with the amount of stitches and bandages you will save.

    It's so funny to me that it likely cost more money on the resin or aluminum...maybe even the sheet metal than it would have cost to buy a brand new harbor freight saw. Of course, the tool was just the muse that launched the creative process that lead to a pretty cool experiment. So, it may not have been practical in this situation, but the technics learned will likely come in handy later on.

    I recently started watching the backlog of videos here.. but it stops at this video, just 1 year ago. From the blog I can see broken links to videos that are now private. What gives? I realize the quality of the previous videos may not be up to par with what you put out today, but just like going back and watching year 1 mighty car mods videos, I would love to see where you started! I really hope you decide to go back and re-enable the videos, warts and all.

    I wonder how you are able to position the blank on the bottom die properly when there's no longer a protrusion to key the blank on the last iteration of gray dies. But regardless amazing as always!

    For the money and time, id rather CNC some toolsteel and use that as a die and punch. Its best to get a CNC machine, or save money for one, because that is really a way to go. You dont want to fool around a mill or a lathe for a long time. You want to be a designer and make things. In the long run, you can get a lot more things done with a CNC machine. I would however make the heat treatment kiln myself though. Its way way more cheap to do that, and it is very easy to do. Maybe saying that. Its easy to build a CNC machine, but i guess its a lot more work than a heattreatment kiln. Im going to upload a heattreatment kiln soon on my grabcad page (check my youtube profile for the link).

    I know it is a rather old video, and you might have already figured it out. I was watching a similar video the other day, where the dies were printed hollow and were later filled with 2 part epoxy. The issue there is the heat that occurs when the epoxy cures but probably possible to use a epoxy with a longer curing time, or just less hardener and leave more time to harden. That could give you more strength than the 3D printing resin.

    Dude! - Before you lose your ring finger, take your wedding ring off. I came close once when my ring shorted an exposed car battery positive terminal connection to a bolt head on the body. KEY-RIKEY it nearly melted my finger flesh away from the bone. (pulled it fast enough to avoid permanent damage) But ! REMOVE ALL JEWELRY BEFORE "GETTING DOWN" TO SHOP BUSINESS. :o) P.S. I enjoy your vids. Your pacing, and vocal delivery (and yes, you're humor) is just the right amount of dry for me. If I were to correct anything, it would be to add another 1/2 second to a pause for a humorous text aside. With the short pauses you currently use, we (me) out here don't know where to instantly look to get the joke without having to back up and replay . That's it. That's all. Well done. Carry on.

    To avoid the distortion did you try cutting the slot for the blade after the forming operation? It would take two different molds used in separate operations to make this with plastic molds. Also this piece was probably originally made when the sheet metal was hot allowing it to be formed easier over metal forms. Obviously your plastic mold can't withstand contact with hot metal.

  • Mat

    waterjet cutter is doing a so much cleaner cut, no burn, and with greater accuracy, also you can cut thicker stuff, and non-conductive materials. Maybe it makes a bigger mess, but you would have to install it somewhere outside. (if the water has abrasive material, the slurry may be hazardous waste, depending on the abrasive material used.)

  • Hunter2323

    @ 13:22, ask yourself, how many parts you are going to make.. get your die fab'd up in carbide, and make a few hundred thousand.. also, in most industries, creating the part is called "exercising" the die.. speed is an issue, as you know when you stretch the base metal, heat is a by-product.. so, metal die is the best way to go, especially if this is a manufacturing process.. sweet work..

  • Hunter2323

    just started to watch this vid.. i am a former engineer at Panasonic America. I worked on the cowling for the Boeing 777 Rolls Royce Engines, which is aluminum based metallurgy. The molecular work is the same for ferrous metals. Get the metal in a form where the molecules become fluid, and then move them to their max position, anneal the base metal, and repeat.. if you are doing all your work at STP, and do not ever anneal, you are "wrecking" the structures that you want saved for the final product. Ie.. it takes 20 process steps to move aluminum 1/4 of an inch, 3D. But, once you get there.. best possible product, which will not shear and fissure apart with micro vibrations.. love your stuff..

    Would be more efficient to print form-molds with cheap material then pour resin into it for the forms. You'll get more control over how the resin sits, and it will be stronger. Also when your form breaks, you don't have to wait 24 hours to print another.

    I think the forms would hold up a lot better if you used them to achieve the detailed shape you want but strengthen them by also making a confining part either with clamping forces around the edges or a rectangular recess that they fit into that is a stronger material such as steel or aluminum.

    Why not design it do that you put the bend in first, and then cut the main hole with the plasma cutter afterwards? It would be easier to set up a jig to do one final plasma cut where you want it.

    Anybody else here because you run presses professionally and wanted to see the likelihood of printing dies instead of having to buy/file a requisition? Makes you think that one day we will see an AI that can interpret product blueprints, design tooling to fabricate parts, print tooling, then begin manufacturing the product autonomously.
