I've been "bit" by neo magnets a few times. I was on the edge of my seat watching you assemble this. 😲

Me too! I think Dom edited those moments out but... he is a careful man, so perhaps he accomplished this feat of daring and danger with zero scars to show for it ;-) You've got me thinking we should do a drama edit where there's tense music building towards the magnet placements. haha.

Yeah, I ended up with some mangled finger meats from both magnet pinches and trying to bare-hand turn those headless threaded rods; and those heavy duty black nitrile gloves in some of the clips were an attempt prevent further injury, but also to try and make sure the bandaids 🩹stayed on. Why did I use headless rods you may ask? We also ordered socket head rods; but the headless rods arrived first. Eager impatience 😞.

You may want to consider the distance between the magnets and the item you are trying to magnetize. Look up the tool that is used to remagnetize or demagnetize a screwdriver. It is simply a single magnet and the distance from the magnet controls if it is magnetizing or demagnetizing.

That's a great point and an excellent thing to look into 👍. We dug into it a little bit today and it looks like they works on the principle of two magnets placed so that the North poles are opposing each other ( we found this great explanation by Dr. Pete Jones/Electromagnetic Videos kzread.info/dash/bejne/c46nu6qFeM-vo9I.html ). The magnetizing hole in the tool is where you're passing the screwdriver between the two magnets. When we think about it, this sort of makes sense, since opposing polarity stacks we've been building/using are effectively a bunch of screwdriver magnetizers stacked together - with the areas between the opposing magnetic fields imparting magnetization to the things that they come in contact with. The demagnetizing hole is where the screwdriver is passed next to just one magnet's South pole. From what we gather, progressively passing the screwdriver farther and farther away from the single magnet's south pole gradually completely demagnetizes the screwdriver. We also found this print file by quattro we may try out ( www.printables.com/model/811329-magnetizer-demagnetizer ). Thank you for the idea to look into this!

Really love the content that’s been published so far! I really learnt a whole lot from your channel and it’s tempting me to get a laser to engrave my 3d prints

That’s great to hear and thank you for watching!

Just came across your channel on my feed as I'm learning how to 3d print. Really enjoy your videos and decided to subscribe. That written, I have to ask, did you do the voice over for the Dharma Initiative training videos? If you haven't you've got a side-gig cause I'm getting 60s/70s training video vibes and I'm loving it.

I thought for magetizing you need strong uniform magnetic field with magnetic lines going through the plate in one direction. Halback array has short alternating magnetic circuits which is probaly demagnetazes plate right after you take it off or move to the side even a bit. On my job we have a magnetizer for sensors which comprized of one big metal square bent in U shape (100+ kg) with one side static and other with adjustable moving block for bigger parts, very big electomagnet really. Parts then were placed in the gap and baked in magnetic field for a few seconds. Ends is about 15x15 cm in size for parts of up to 10x10 cm. I'm thinking 2 neodymium magnets with field oriented in one direction with gap between them and far ends joined with stiff u-shaped metallic rod will work better. Or just use one big magnet and move it with one pole being on the plate, likely it's good enough to magnetize without going though troubles of assembly.

Your content is amazing! Keep up the great work! I'm pretty sure you've answered this before, but what filament are you using with what machine/laser settings to get those gorgeous etched labels on your prints?

We've often used black Polymaker Matte PLA for these magnet projects, but we've also used black Elegoo PLA Pro (which is a bit shiner) also etches well. These prints were done on a Bambu X1C and etched with an xTool F1. You can learn more about our process here kzread.info/dash/bejne/gIV5qbqvoLW8dKg.html and and can find sample files here www.batchmade.studio/laser-engrave-3d-prints-part2

You went full nuts on it. Doing the "Research" part in the name justice. I'm really impressed you had the guts to build it with such monster mags... Did you test the field strength by any chance? Or a max kg able to lift? Also I meant alternating array of Halbach arrays out of tiny 2mm cube magnets, but apparently it didn't occur to me to communicate that. My bad...

Then again.. probably doesn't matter. If the stuff is saturated it's saturated. The stack of disk magnets is way easier to assemble.

Hey there, I'm Holt, another of the Batch team. I'm replying for Dom while he's on vacation, but I'm sure he'll chime in when he's back. I know while he was working on this one he said it was scary a few times, so I'm assuming it was beating him up pretty good. We were super surprised that it totally killed the sheet magnet so quickly. It would be pretty cool to test the lifting capacity too. I feel like this is heading into fishing magnet territory. It would definitely do some damage to a finger or hand. It's not for the faint of heart that's for sure! Thanks for checking in. I'll let Dom know you popped in when he's back this weekend. On to the next project!

Not really sure we'd call it 'guts' 😅 . It really was more blind-hope-in-a-theory which morphed into we've-gotten-this-far-so-we-can't-stop-now 🤷‍♂🤣. We don't have the instrumentation to accurately test field strength, and would need to figure out how to test lift max without risking busting that little bit of PLA keeping the rod in the handle 🤔. But if we do, we'll chime back in here 👍. - D

Not sure that the asymmetry is beyond our understanding. Would seem to be a positive feedback effect.

Magnetic fields affect each other. They are not like light waves. Put a north next to a piece of iron and it will induce a magnetic field in the iron. If you simulated the interactions between the magnets, I am pretty sure you would see how the effect emerges.

Thanks. As you can probably detect, we’re learning as we go. Our knowledge on this leans more practical than scientific 😅, and we tend to dig in primarily to the places where we hit obstacles we can’t circumvent.

What machine you use to laser the parts? Great content ❤

There is a link in the description of that video ( kzread.info/dash/bejne/jGiX2cxrj7nIis4.html ) that should take you to the write-up of that project ( www.batchmade.studio/magnets-and-3d-prints-part2 ) . At the bottom of that write up is a 'Materials Reference' pulldown. You can find the fabrication files there (3D print and xTool F1 engraving files).

hello, can you please make a video about "Can Xtool welding 3d printed parts like abs, petg or pla" pls answer on my comment, its really interesting

@@batchresearchlab I have a short video on my channel how it looks like on a motor stator. It works great

So one thing I thought I would mention, is that I knew when you made that video that it wasn't a "halbach array" but I actually thought it was a good name because i presumed that was the magnetic configuration you were imparting onto the flexible magnet. consider the magnetic fields of the opposing polarity stack and then imagine the field configuration of the flexible magnet that it should adopt after being... uh... "treated"? I do not know the right terms for this. Reverse Polarity Stack should look like this: ⬅⬅🔃➡➡➡↕⬅⬅⬅🔃➡➡➡↕⬅⬅ Flexible magnet should then look like this: ➡↗⬆↖⬅↙⬇↘➡↗⬆↖⬅↙⬇↘➡ That's a halbach array right?!

😆I guess you're right! We didn't even think about it that way! I guess we were just overly concerned that our mistake would end up misinforming people that we immediately took steps to begin to try and correct and clarify things. And wow, the way you can 'see' magnetic field interaction is beyond our current capability....like how an Operator in the Matrix can see what's in the digital rain 😳. This might be the first time we've actually seen an 'applicator' array's field pattern diagrammed immediately adjacent to a 'treated' magnet's field pattern🤔. Thank you for this insight🙇‍♂
