Check out the subreddit: tinyurl.com/smhere
In this video I show more techniques for 3D printed sheet metal press forming tools. I improve over my previous designs by making a tool with a moving action as well as fixing a major design flaw. I also demonstrate a more complicated forming operation with many features made in one pressing.
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: www.patreon.com/stuffmadehere

    For highly complex parts, you should consider creating (I forget the technical name) holes in the bottom of the dye that can be used to push the part off the dye, like whats used in plastic injection molds. Youd have to add another part to the dye to plug the holes for the release pegs, but I think it would save alot of time removing parts from the dye. Really cool work!

    • Elizabeth Greene
      Elizabeth Greene

      "Holes for Ejector pins" I think is what you mean. Another option would be to split the "sticky" die into two parts so the second part can push the workpiece off. A third option is even more draft (taper) to help the parts not get stuck. I don't think that last one will work though; Metal "bites" into plastic and doesn't want to come off. I read the intro chapters of a die design book last night and was blown away. There is a huge amount of tech that goes into production dies that I would never have considered. Yeah! More things to learn!

    I've worked for almost 7 years in sheet metal manufacturing. I find it impressive how close to actual tools and methods you are getting with what I assume is no or limited prior knowledge of sheet metal. Your rotary benders are extremely close to commercially available ones.

  • GrimResistance

    When you're cutting them out, start the plasma arc in the middle of the waste material and then move to the cut line. That should give you a cleaner cut.

      @Izlarik you can see him staggering cuts near the end of the video

    • Izlarik

      @mick0maticNL It's also recommended that the cuts be staggered on large cut to blank ratios like this because of the heat-warping. It can help reduce the warping by displacing the heat more evenly. Which may make it sit in the tooling better, resulting in a better finished product.

    • mick0maticNL

      @movax20h Yes thats true, i only mentioned it so it can atleast be a bit better than what it was before, still its not perfect. Gotta use the tools you have to make the best out of the situation right :P

    • movax20h

      @mick0maticNL yes you are right, one should start from inside of the waste material, far from final edge. But you can see that the main issue is power level and speed, because even whole edges and holes that had constant feed, had these issues, not just the starting point.

      That's genius for you. Someone who not only understands what he's doing but also has the communicative skills and empathy to understand how to convey and explain these things to another person. A lot of smart people lack the social skills to understand how to explain their ideas at a level others can follow. And end up rambling about specifics without having properly conveyed core principles. Understanding an audience you're talking to. To be able to give them a why, how that actually captures them, which they can follow. He would be a great teacher. But we need this guy in other fields. He can make educational video's, do projects for himselglf and business and probably achieve more than teaching in academics. Being part of a college research lab wouldn't be bad though maybe.

  • Cam DAhawkdriver

    When I used to work in a factory while going to college, forms were often two steps. However the way they got around that was to have two parts pressed at a time. The result is that you’re getting one part per press. The complex dies often had a mechanism that “ejected” the part by pushing the part up from the bottom, which helped when transferring part one to part two in the die set. Even complicated dies involve multiple steps. If you’re mass producing, at a minimum you want one part per press. Good video!

  • Mat

    normally for bent parts you want to anneal them in an oven afterwards, to remove residual stresses when entering the plasticity zone. The annealing process (temperature, timing, and cooling ramping) would depends on the material you have bent. If you don't anneal them, depending how they are loaded in service, they can fail early in fatigue.

  • Dominique Hebert

    This is great stuff, and great video that's super informative. Really clever ideas, thanks for sharing Did you ever think of drilling a couple holes into your mold. You could reinforce them with metal tubing. At the end of the tubing on the outside, you could attach an air quick-connect. When the part is fresh off the press you could attach an air hose and run some air through it. They use that process to produce all kinds of products right now. It just might work for your stuff. Hey, just a thought, and thanks again.

  • Hiddenrage1

    I like what you are doing. I'm a die designer and my work never let me try experimenting with plastic printed parts. On the second die you need a stripper around the punches that are forming the flanges. A stripper holds the part firmly in place before forming is done and holds the part down while the punches are being withdrawn from the part. Keep up the good work!

      I think it's totally awesome. And that this young man is so very brilliant. I am so jealous of his talent. Yea you may not go to this much trouble and cost to make a 2 dollar part for a 40 dollar tool. But....there are always those unobtainable parts at any price.so being able to produce one yourself is priceless..

  • micjr21

    Really like your videos Glad I subscribed. If you were trying to make a lot of those parts the only thing I would try is maybe some spring-loaded push pins in the bottom of your form tool to evenly push the part off of the form tool when you released the pressure of the hydraulic. But that would be a lot of work to make that for only a few parts

    In the same way as the difference between static and dynamic friction, is there a difference in resistant to bending force when beginning to bend versus continuing to bend?

    You could add some through holes to the die for ejection pins to pop the part off instead of trying to pry it off. You would need to make the overall size of the die larger than the part so you had something to rest the die on when pressing it out. You could get really fancy and make them spring loaded so the part ejected after releasing pressure form the press. Edit: I noticed after posting this that several other had the same idea. lol

    Nice project. The benders are called ready benders. I wonder if you could have a small step between the filet and the knife to relieve the pressure so that extraction is possible.

  • Leenet

    Great work, the reason the first too broke up is due to the same springback as you saw on the first part, the flanges formed will spring back. By reducing the form tool height, there is nothing for the material to grab. Keep up the good work.

    A little tardy to the party (I've been binge watching these cause your channel is amazing) but if you put some strong springs on the bottom (kinda like in pt.1) but on the bottom, it'll push the part out so you don't have pry it off

    thank you for this video @stuffmadehere, very clear usefull. Now my suggestion for Part 3 video: - Could you please add some screenshot of the drawing to see the radius and springback consequences? - You can increase the dimension of the metal sheet and cut later the leftover length. - You could add bars in the mold, as you tried in the first attempt. - As in previous comments, add some holes in the middle of the 3d printed mold, and they can be used as pins to take the bended part out. Also said, about dividing the mold. Then your Part 3 video probably will beat your already successfully Part 2 video, with even more views. It would be a case Study, 3D Printing Success Storie You won my thumbup and subscription.

    Really liked the video. You could consider adding 'rejection pins' just like a injection molding machine has. I mean to add holes in tho bottom mold, so you could put pins trough and eject the part. Geep up the good work!

  • River City Fishing
    River City Fishing

    This is ever so clever! All I might add is to remember to cook the parts in an oven so as to remove the constraints that were applied to the metal during the bending process, in order to strengthen the bonds. They would look mint after a surface treatment such as a cataphoresis coating or Delta protekt 🤘

    Prying it out: you could leave a square cut(s) on the 'floor' of the die, running to the edge, then put a block(s) of the size of the cut(s), plus some extra as a 'handle(s)' sticking out of the die. Then just press down on the 'handle(s)' to lever the part out of the die.

  • SierraEcho88

    I am a mechanical engineer and I am seriously impressed by your design, good job. Would you say FDM or Resin is the better option for the tools ? Also to release your part easier from the tool you can increase the draft angle and create holes in the tool to push the part out from behind, like in injection molding machiunes.

  • pmac124

    Great video, I was thinking about using this processes for a class design project. One question I have is would you have a recommended gauge of stock material that would work well with PLA filament molds and a simpler car-jack press? Later versions I can get machined metal but I want to prototype the form first with a lighter gauge metal so I can use cheaper molds/ don't have to buy a harbor freight press.

  • Joël Cadieux

    I suggest you leave a slot on two opposing corners to use as "ejection slots", where a tool arm can eject or pry out the formed piece. You could also do this using a through hole in flat sections of your die press and then print the corresponding ejection pins to avoid marring your formed piece.

  • gs242

    These two pressing videos are he first two vides i watch from your channel. Very interesting and entertaining. I work as a design engineer and designs productions machines towards the med-tech industry so designing and produce parts is my day job. The funny thing with your iterations it that they follow my mind exactly, When you do each test and get the result, my mind goes, hmm, maybe i should have tried to do this instead, and the next step is you doing exactly that, the same idea that i had. One idea that would be fun to see you try is to shape the edge at the samt time. So you get fillets all round the edges and an more rigid/stable part. By doing so you can make a recess that you fit the plate in to align it, then when you press it goes down into the form, forms the metals with rounded edges and it should be no problems to remove it. You might also be able to combine it with the rolling molds to make sharp 90° edges all around at once, That would be really impressive. Keep up with vids, I love them, The deeper and nerdier, the better :)

  • psidvicious

    That rotating die idea is brilliant! 👍

  • Patrick L
    Patrick L

    Very innovative approach, I love it. I have a PlasmaCam and a 3D printer and was tempted to try this. Looks like you are using a resin bed 3D printing process which produces much more solid/homogeneous/stronger plastic parts than a filament type printer. Unfortunately nearly all of us own the filament type printers and I am guessing that if I duplicated your process with my 3D printer the die will explode immediately due to the weakness between the layers. I struggle with this on some designs that are in tension (like the die in some directions) . What are your thoughts about this?

  • stevebray71

    Love the videos and you've earned my subscription, but when I've seen parts being made in the way that you've shown they normally have extra material that gets removed by a last process to clean up the edge's and stamp them to the final outer dimensions just a thought that might be of use in any future things that you might want to make in the future & it might help you out with the way that the edge's came out in the flat sides look forward to seeing what you come up with next time 👍👌

    • Dan

      Right, I've seen more complex parts go through series of dies that more progressively reach final form, often with metal heated first, rather than all at once cold stamped. Though I'm not industry at all so i could be entirely wrong

    You could use mold keys to help the dyes align perfectly. And waste a little extra material as buffer on the borders of some parts as necessary to keep edges flat. Can always be trimmed after
