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.
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!
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.
@@movax20h I still think GrimResistance is right, look at the cuts, he starts and ends them on the edge of the part on the same spot. Offcourse its going to leave a rough spot on the start and endpoint, he could atleast solve that problem by changing settings i think.
@@mick0matic 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.
@@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
@@mick0matic 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.
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.
These videos are some of the highest quality, most in-depth, and most watchable engineering videos on RUclips. You cannot change my mind. WHERE HAVE YOU BEEN ALL THESE YEARS? Keep em coming!
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!
I replayed the clip at 5:55 half a dozen times, each time at a slower playback speed. Super satisfying to watch the fruits of deliberated research and development.
As someone who works as a Tool and Die Maker this is very inpresive when it comes to how fast you picked up and corrected your mistakes ! Good Job! And maybe see if you can get some Ejectors of some sort :)
I found part 1 and 2 of this series fascinating! I have a 3D printer and have really enjoyed learning how to design things in CAD and then print out stuff that's useful I can use around the house or in my car. Once again, excellent content; you earned a new subscriber.
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!
The Aesthetic of the slightly rough parts is... Kind of industrial and I'm into it.It's so clean and professional, but there's the tiny bit of human crafting to it that makes it feel... Like, personal? I guess? In any case, I love learning from your videos, I like listening to your voice, and I like watching YOU learn at the same time. It's like being invited into the process. Thanks for making these.
you designed a press tool with no space for the material.???!! oh well at least you got it right the second time. good video. i will be making some of these tools soon.
Dad: "Are you winning son?" Stuff Made Here: "Define winning" Dad: "Did you accomplish what you set out to do?" Stuff Made Here: "Yes" Dad: "Wait...why did you make me define it?" Stuff Made Here: "Because the raw material cost greatly exceeded the cost of the part, not to mention the sweat equity" Dad: "All I want is what is best for you, I love you son" Wow, that ended differently than I thought it would, and I'm the one who wrote it.
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..
I like how you mix technologies. A lot of people try to use just 3d printing for a project and then get upset because it isn't perfect. 3d printers are just another tool like a mill or plasma cutter.
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.
My professor told me spring membranes are formed like this in production. Nice to see some video similar to it. I had initial doubts about the soft plastic forming the much harder steel
I've watched enought of your videos to get sheet metal company advertismenst... Such fools, why would I need such service, after aquiring the knowledge you convey
I love that when you say some up grades at -0:48 it sounds like you are saying Smug Grades! BTW you have the best channel on the internet, please do not stop.
The double hinge approach is genius and very satisfying to watch! And I do agree that beeing able to print the tooling instead of maschining it is a lot more accesable. Although I doubt that a lot of people own a 3d Printer and a cnc plasma cutter. But I guess that could either be outsourced or exchanged by an alternative method. Maybe their is a way to stamp the desired form out of the sheet metal?
I am so glad I saw your channel if I am to be honest I kept on seeing your basket ball hoop and ignored it. However I found these videos and am glad I saw this. Very cool stuff.
I am currently working on a design for forming microchip legs to a 90degree angle. I was having trouble with the elasticity of the metal legs and am quite happy having found this.
I am in no way an engineer but man your videos are so mesmerising. Just wow. I ain't religious either but God bless you my dude you're a damn mechanical genius.
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
Glad you figured out the clearances... I watched the previous vid and was questioning whether there was adequate clearance for the thickness of the sheet metal.
As a former tool and die maker this was interesting how a hobbyist goes about this sort of thing. I could see using 3d printed plastic in conjunction with machined metal ones being a good option for prototyping.
Yeah I've been thinking about that - basically put the metal where it is really needed such as high wear points or high stress points and let the rest be plastic. I bet that would work well
Haha I get cut... a lot. I try not to but nothing seems to work. Then when I'm editing the video I'm cringing at all the bandages. Glad you get a kick out of it :)
Hi there, this channel was a suggestion and am I glad it was, you have a new subscriber added to your list after seeing a practical solution for making printed parts to make forms for a press, bravo on the use and I look forward to seeing some more of your videos.......Phil 👍
Nice. Just watched the first video on this and thought to myself: "Maybe there is not enough clearance for the metal to go into." Thanks for showing this and "admitting your faux pas". Because often times you come across similar issues and don't realize them. If I would own a 3D printer and a workshop AND do stuff like this, I would write that down in some memo in order to check when this would happen to me. Unfortunately, I own neither but if the day will come, I will remember. Until then: I will just watch your cool videos and see your channel grow. Keep it up.
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!
Where did you come from man? The topics you cover are super interesting (I'm a 4th year mech Eng student) and your videos are also high quality - reminds me of Ben Eater in some ways! Great work. :)
I've experienced this quite a bit. I learned drafting manual drafting in his and 2d cadd early autocad. I've made the transition to solid works because work uses it but have had to relearn drafting with linked stuff like you clearance issues. Then I am a hobby machinist but I'm all manual and work wanted to add additive manufacturing to our setup so again thinking a new way. Wild ride but now I know more things so yah.
i have designed this style of tooling for a company making wood stoves and gas stoves, it was used in a number of different parts, tens of thousands of parts per year over many years, my tooling was made of different types of tool steel, my design did not use rounded bottoms on the moving parts, the bottom was flat, the holder had the opening with the bottom tapered toward the center, along the center line of the holder were rubber blocks that kept the moving sides opened up past 90 degrees, when you pressed your part and the top tooling reached the bottom it compressed the rubber at the same time the moving sides over bent the part so after spring back you would have a 90 degree bend, as the press moved up the rubber pushed the moving sides up and released the part, so in short the two moving sides rotated on their outer lower corners, a pivot point. hope this is clear as mud lol
Awesome, excellent Research & Development!!! I love the people making things just to see what happens and design a thinking path, i really do believe with these actions we get out of the cave after long time
When you say it worked much better then expected I hear Ben from applied science Awesome videos keep up the good work I’m gonna try this process with al
I hadn't thought of using air channels. Good idea. Given that the parts are 3D printed it should be easy to incorporate several channels that lead to a single air gun blast hole to eject the part. Will try that on future tools!
You can drill holes in the bottom form to push the metal off from underneath with a wooden dowel, or another printed piece to push through multiple holes at the same time!
Curious how much improvement you've made on this concept in the past half year. I'd like to see updates, especially on complexity of bends and forms, and complexity of finished parts.
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.
Very cool, not to mention you can even make a hydrolic press out of an old 20 ton jack if you're just starting out with sheet metal stamping. A start up cost of only about $500 at the cheapest.
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.
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.
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 🤘
In tool and die making we have multi part tools. Either the inside or outside edge of the tool comes down to pin down the piece before the actual part of the tool applied pressure to form it. On the bottom we had spring loaded pins or even two part lower die to get the part out of the form because they are impossible to pry out by hand. This is my experience from tools made for exhaust parts. And you are right than complex forms and materials need multiple steps. You should also make the tool bigger than the part so you can add either a recess to center the raw part or just pins. You should also add centering pins on the bottom part and holes on the top to align both tools 100% every time.
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.
If you want to remove the drip tray part from the tool, you could either try to cool the mold or heat the part. The part is metal, so it might be easier to heat that without transferring that heat into the mold, but that might be a fine balance to try and strike. You could also just try throwing the whole thing in the freezer, and then pulling it out and hitting it with a hair dryer. The mold and the plastic will both heat up, of coarse, but the metal will get hot much faster than the plastic which might allow it to expand at a faster enough rate that it you might be able to just pop it off at the right moment. You could also try to lubricate the male side of the mold itself with water before starting, then throwing it in the freezer and just allowing the water in between the mold and the part to freeze, expand, and pop the part off pretty uniformly. Kind of like how tiny drops of water seep into the cracks and concrete and cracks it apart, but in a controlled way.
Im a deep draw and metal stamping engineer who started as a tool and die maker. Your killing it buddy message me if you need any help your very close my friend!
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.
This is an amazing process with great looking results. So with a $200 press and a $200 3d printer you are most of the way to a versatile metal bending setup! Now if you show how to make a cnc plasma cutter we will be all set.
I confess, I kinda skipped most of the first video, and now I'm seeing this working _way_ better than I expected it ever would. Really thought the forces on the plastic would be too much. Really impressive job.
In sheetmetal design, there are two ways to get such parts of your tool. One would be mechanical via the tool beeing two-part and having a punch in the middle. Then there is pressurized air. I think for 3D-Printing you can just take out three circles in your tool from which you can press the part out later. These can also be features of the tool itself, just seperated from the rest.
This brings back memories of my fly press operating days forming channels in 12" × 8" aluminium plate, in cross section the press formed almost a cylinder like the letter Omega. A few hundred of those and my arms ached like mad. The gorilla bicep machine.
I am currently working on a press tool prototype. If mine doesn’t work, I am definitely trying your idea with the rotating parts! Really well done. Thanks for the inspiration.
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
BRO! I print a ton of tooling for sheet metal and castings but your little dual-barrel hinge thing is sooooo clean!! I'm totally stealing it. thanks man. I owe you one. Thanks for teaching me.

i have designed this style of tooling for a company making wood stoves and gas stoves, it was used in a number of different parts, tens of thousands of parts per year over many years, my tooling was made of different types of tool steel, my design did not use rounded bottoms on the moving parts, the bottom was flat, the holder had the opening with the bottom tapered toward the center, along the center line of the holder were rubber blocks that kept the moving sides opened up past 90 degrees, when you pressed your part and the top tooling reached the bottom it compressed the rubber at the same time the moving sides over bent the part so after spring back you would have a 90 degree bend, as the press moved up the rubber pushed the moving sides up and released the part, so in short the two moving sides rotated on their outer lower corners, a pivot point. hope this is clear as mud lol
Awesome, excellent Research & Development!!! I love the people making things just to see what happens and design a thinking path, i really do believe with these actions we get out of the cave after long time
When you say it worked much better then expected
I hear Ben from applied science
Awesome videos keep up the good work I’m gonna try this process with al
You could print through holes in the form so you can push the sheet metal out using a jig with pins
This, or give it a quick blast through these holes with the air gun as not to marr the surface
I hadn't thought of using air channels. Good idea. Given that the parts are 3D printed it should be easy to incorporate several channels that lead to a single air gun blast hole to eject the part. Will try that on future tools!
Thanks for another excellent of demonstration of using 3d printed parts to form dies. Lots of great ideas to take away.
I was the guy who your talking about in the end of the video, I didn’t enjoy any of this but watched every second.
Such an obscure title and the video has 2M views. Such a great channel
Impressive and interesting as well . A younger version of this old Tony. I like your presentations. Subscribed

You can drill holes in the bottom form to push the metal off from underneath with a wooden dowel, or another printed piece to push through multiple holes at the same time!
Can't believe i just found your channel. this is gold mine
The moment you showed your tool at 6:50 I was thinking I've seen that on my espresso machine. Strange how it has a signature look.
3d printed progressive tool and die very awesome! This channel never ceases to amaze me.
Never thought a 3d print would be this durable
This dude is so next level. Blows me away every time
Curious how much improvement you've made on this concept in the past half year. I'd like to see updates, especially on complexity of bends and forms, and complexity of finished parts.
He's been to busy making melee guns
I watched the first video and now this one. I really like what I see and I have learned a few things about my 3D printer! Subbed and rang the bell!
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.
Yeah that should work. Sounds like another way of doing ejector pins. I'll be incorporating this type of feature in future tools.
Nice stuff! Time lapses of the printing process would add some nice b-roll.
For alignment, possibly oversize the blank and add registration features.
+1 for the B-roll.
Very cool, not to mention you can even make a hydrolic press out of an old 20 ton jack if you're just starting out with sheet metal stamping. A start up cost of only about $500 at the cheapest.
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.
This is the video of yours that I stumbled upon where I instantly subscribed. 😎👍💙
you can make the plasma cutting machine start the holes for that part from the middle so that you don't get that imperfection
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.
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 🤘
In tool and die making we have multi part tools.
Either the inside or outside edge of the tool comes down to pin down the piece before the actual part of the tool applied pressure to form it. On the bottom we had spring loaded pins or even two part lower die to get the part out of the form because they are impossible to pry out by hand. This is my experience from tools made for exhaust parts.
And you are right than complex forms and materials need multiple steps.
You should also make the tool bigger than the part so you can add either a recess to center the raw part or just pins.
You should also add centering pins on the bottom part and holes on the top to align both tools 100% every time.
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.
If you want to remove the drip tray part from the tool, you could either try to cool the mold or heat the part. The part is metal, so it might be easier to heat that without transferring that heat into the mold, but that might be a fine balance to try and strike. You could also just try throwing the whole thing in the freezer, and then pulling it out and hitting it with a hair dryer. The mold and the plastic will both heat up, of coarse, but the metal will get hot much faster than the plastic which might allow it to expand at a faster enough rate that it you might be able to just pop it off at the right moment.
You could also try to lubricate the male side of the mold itself with water before starting, then throwing it in the freezer and just allowing the water in between the mold and the part to freeze, expand, and pop the part off pretty uniformly. Kind of like how tiny drops of water seep into the cracks and concrete and cracks it apart, but in a controlled way.
Im a deep draw and metal stamping engineer who started as a tool and die maker. Your killing it buddy message me if you need any help your very close my friend!
Very informative video, earned my sub. looking foward to more great content like this!
This video well help open a whole new world for makers. Well done!
Great second part of this exciting series. I can't wait to see some more inputs from you :)
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.
This is pretty amazing, and will revolutionize stamping technology
If not revolutionize, it should at least decentralize.
@@ColburnFreml yes good point
For your alignment issue, you can put borders on the lower part that wraps around the upper part so it also aligne the metal part
This is an amazing process with great looking results. So with a $200 press and a $200 3d printer you are most of the way to a versatile metal bending setup! Now if you show how to make a cnc plasma cutter we will be all set.
I made my plasma cutter and it really wasn't too bad. I plan to do an overview of it soon
I confess, I kinda skipped most of the first video, and now I'm seeing this working _way_ better than I expected it ever would. Really thought the forces on the plastic would be too much.
Really impressive job.
In sheetmetal design, there are two ways to get such parts of your tool. One would be mechanical via the tool beeing two-part and having a punch in the middle. Then there is pressurized air. I think for 3D-Printing you can just take out three circles in your tool from which you can press the part out later. These can also be features of the tool itself, just seperated from the rest.
This brings back memories of my fly press operating days forming channels in 12" × 8" aluminium plate, in cross section the press formed almost a cylinder like the letter Omega. A few hundred of those and my arms ached like mad. The gorilla bicep machine.
I am currently working on a press tool prototype. If mine doesn’t work, I am definitely trying your idea with the rotating parts! Really well done. Thanks for the inspiration.
Sounds like youre using Inventor. Great tool. Might make a tool like this to sink a countersunk bolt into sheet metal.
That's awesome! I'm amazed by the quality of the parts. Thanks!
Ready benders have some very cool engineering :) Good work!
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
