This channel is the number one reason of why I’m getting a 3D printer (and some bags of concrete)
@evanbarnes9984 Ай бұрын
Dude I think my 3D printer might just be my single best purchase ever. It's a toss up between that and my paraglider. I know this won't be the experience of basically anyone else, but purchasing a 3D printer directly led to me getting an incredible new job that perfectly matches my interests and skills designing robotics toys. I was a teacher before that. Even if that doesn't happen, 3D printers are incredible tools. I used to think they were just for printing flexible dragons and iron man helmets, but they're quite possibly the single most versatile tool humans have ever created. This channel really showcases that fact. Just do yourself a favor and don't go cheap. There are a bunch of great mid range options out there now that are absolutely reliable workhorses. I know people love their Ender 3s for whatever reason, but I've never seen someone use one of those without immediately spending the price of the printer all over again on upgrades just to make it usable. Personally I love Prusa. They are more expensive, but we use them at work to prototype injection molded parts. They have thousands of hours of print time on them, and never once have we had to do repairs on them. I just keep the beds clean and the filament dry. Also they're FOSS/OSHW, and that kicks ass. We also have Bambus, and they are faster, but they're a bit less reliable. We've had some break down already. They also aren't as dimensionally accurate, but I think that won't matter as much for most use cases. Good luck on your printer adventures! It's a super fun world to get into.

Printers are only as good as the effort put into tuning them. I was given an old CR-10 mini that had issues. I took it apart, cleaned everything, reassembled, and tightened a few things that had been loose when I got it. Added a couple washers to space the z lead screw a bit better. The original build plate had issues on almost all of them, so I replaced that with a mirror tile for a few bucks. Replaced a few of the roller wheels that had flat spots in them. All total, I have about 20$ into "upgrades", and it prints as dimensionally accurate as I'll ever practically need after a few adjustments from calibration prints. Like press fit parts accurate. Mind you, the rollers were the only thing that needed replacement on a machine with several thousand hours on it. I still want a Ratrig or Voron at some point, but there's a reason people like their ender3's and clones of them. They're inexpensive, and after tuning, they just work.

@@mid88night I sometimes joke that I used to have an Ender 3, but now I have an Ender 3 frame with a completely different printer on it. But in comparison, I have a Magneto X now, and that thing required no tuning besides setting a bed mesh. I actually went through all the standard stuff and ended up pretty much the same as how it started. I think the Bambu printers generally have an experience like that too, although they're a bit more proprietary when they don't need to be. Personally I think 3d printing is getting into a pretty great place where pretty much anyone can just pick up a well tuned printer and immediately start printing with cheap engineering-grade materials like PETG-CF that are commonly only $25/kilo. Even PET-CF is getting down there and giving polycarbonate a run for its money.

you should consider with putting the lever gear behind the rack. that way you will push down on the lever instead of up, helping the press body not fail. awesome design too. maybe if the rack was a bit thicker, the forces would be greater. keep up the awesome work

Nice video. With respect to the concrete, it seems like it's normally in tension and shear (while the press is pressing). Concrete is strongest in compression and worst in tension, so it seems like it'd be useful to post tension the concrete to preload the structure. That way it'd be in compression until you overcome the preload force of the post-tensioning. Granted it's moot since the concrete isn't the weak point of the press.

I would love to see the limit of the other parts of the design by you iterating a few more times on the rack teeth until they’re not the failure point. In principle if you have high strength concrete shaped in relatively favorable triangles of the given inner dimensions providing a strong base for a lot of leverage. It’s not that surprising the thinnest plastic feature is the first to go, for sure. You are a great toolmaker and craftsman, excellent work!

Figured I'd compile some of the most useful tips on your hardening process: Use a higher alloy steel. These can be commonly found as "Grade 8", "12.9 metric" or "Alloy steel" bolts. These have more 'potential' for hardening than mild steels, which most cheap bolts will be made out of. Use a stirred ice/salt water quench instead of an oil quench. Oil quench is most common on tools where it is useful to trade a small amount of hardness for increased ductility. Your punch will not need ductility to resist impact, so try to make your quench as harsh as possible. If you can enclose your part while you are heating it, even between a few common bricks, you will find that you can reach orange-hot temperatures much easier. The camera can be deceiving, but it seems that what you reached was red-hot, which is below the heat treatment temperature for many grades of steel. Best of luck!
@DaveEtchells Ай бұрын
Excellent tips, thanks for sharing! (I hadn’t thought of using 12.9 bolts as hardenable stock before. What’s their alloy, do you know?)

If you are unable to locate higher grade iron for hardening, see Chris' (Clickspring) video on case hardening as an option. I'm not going to suggest it is better than using pieces of drill rod annealed for shaping and threading, then hardened and tempered, but it's better than not doing anything.

Might be worth a try?.

@IdRatherBeMaking Ай бұрын
Nice! I've made some crude concrete based machines but WOW, yours look better than mine! I have suggestions! You may want to consider is putting the rods through a single metal plate on both ends. The plate will increase the compression on the concrete, tie the allthread together, and give you a stronger part. The way it is now the nut only compresses the concrete directly under the washer and you could crack it in the space between the threaded rods. 2) I started 3d printing funnels to guide the concrete into the form, if you run tape around them it keeps the concrete out of the layer lines and makes it much easier to fill. 3) for the rack, consider tying in another geared rack on the back. More threads will give you a stronger column. SO CLOSE! :)

I think you might have this backwards. The pinion gear on the shaft from the handle needs to sit behind the rack, with the rack gearing being on the back of the rack. That way, downward movement of the handle translates to downward movement of the rack, which should reverse the load direction the frame is seeing. At least, that seems correct in my mind. The rack/pinion teeth will still be the weakest part, but I’m curious what moving the pinion behind the rack would do. Loved watching this though!
@kyleisah Ай бұрын
Yeah, with every arbor press I’ve ever used, the gearing on the rack is on the back, and the handle/pinion shaft and gear sit just behind the rack, which translates the movement that way.

Have you considered replacing the rack with a course thread 15-20 mm bolt with 3d printed guides to square the profile up through the press? You are after all, already using an M8 bolt or all thread to compress the layers in the rack, You would need to change the helical gears angle some, and could include extending the threading shape across the square profile the bolt is in to hopefully reduce the stress on the driving helical gears.

Long time enjoyer of your videos, thank you so much for this series. I think I came up with a very interesting idea for a limitation I can tell you fought with. For a press there is a balance between parts accessibility, and the presses core strength. But what if you could have both options depending how it was configured at use? Basically to get down to it, a nice chunky bolt that can be installed right behind the press arbor or at set increments of depth. If increments were used, you could even leave multiple installed all in a row for added tensile strength, until a part dictates a needed clearance. With this idea a lot of the forces generated would be shunted into the metal instead of flexing the concrete and mesh structure (simply having one installed, would turn that force back into a compression load.) Also I wonder if your gears would be more robust in Nylon, ASA, or maybe even PETG.

Tip. Try to print every thing at a 45 degree angle. Prints often get much harder that way because each layer get a larger area to adhere to the previous layer. Check Slant 3D he talks much about that.
@Yy-ig6fm Ай бұрын
The steel you used for the punch may have been austenitic stainless, which isn't hardenable. It would be better to use high carbon non-stainless steel because it's easier to harden without weakening it. There are lots of stainless steels that will harden up too but they usually have a more involved heat treating process with holding times and are less tolerant of mistakes. For your application you can just hit some carbon steel with a blow torch to a red glow. (not yellow, not orange) and quench in oil. Then if you feel like it you can heat treat at about 175c in your oven for a couple hours to make it less brittle. This will drop the hardness obtained after the quench a little tiny bit, but this will give the part a lot more strength compared to using the steel without doing so.

you have a partial tooth failure because the forces are pushing the rack and pinion apart. the more you push down on the bar the more force is acting against you in friction and in deflection and the deflection is also decreasing your grip. all to say that you made a press with a compliance based cap which would be great if you needed to ensure that can't exert more that 100lbs on a part that is more expensive then the press
