[@domramsey]

Amazing project. But you didn't show it closing? Isn't that and the keyboard mech the most important part of this laptop?

[@polymatt]

Yup. Good catch. I eluded to some bowing issues of the bottom case. It’s currently preventing the laptop from closing completely. I’m kicking myself that this part of the explanation wasn’t in the final edit. Currently trying to figure out a way to flatten it because those 2 extras millimeters are preventing a smooth close. 😔

[@milescarter7803]

Seems like the best use of this would be a "frame" and then attach a sheet of metal to the large flat surfaces? Obviously that require more fasteners etc. But in terms of for example creating your own bespoke Chassis to use a commonly available lid with EG a Framework or Steamdeck motherboard. (Edit: I should have watched to the end 😅)

[@aarontrupiano9328]

[@Longplay_Games]

I was literally explaining to my spouse how awesome it would be to use this method with a framework internal to make a cyberdeck, and then you said it like 30s later. My spouse was like "Oh, I see why you're watching this then" Awesome work, looks really cool, and who doesn't want a laptop they can batter a door down with?

[@polymatt]

Great minds :). This project has seriously made me consider building a crazy cyberdeck!

[@JohnNorrbin]

See? I told you it would be sweet to make it out of metal :D Turned out amazing :D Just one thing. I would put some isolation on the edges of the PCBs, i noticed that you put them in without it. The different layers of the PCB can in worst case end up at the very edge of the board. Slight sanding of the boards by putting them in and out, or any slight burr could cause those to touch the case, making a short between layers. Instead of vinyl, you can also use Plasti-Dip, like the stuff people spray their rims on the car with, to get a different color. This is basically liquid tape. You could have just sprayed the inside of the case, and used a brush on the edges, and called it a day :D

[@polymatt]

You totally called it - and great thinking on the PCB edges! I hadn’t thought of that. I did think of the plastidip route but in my experience it’s really not that durable and breaks down over time. I wanted something that was a little more stable!

[@JohnNorrbin]

@@polymatt Yeah the vinyl is much more durable just higher effort. But the whole project was extreme effort so makes sense 😎

[@briangoldberg4439]

Speaking as someone who has 3D printed a lot of housings, a good easy way to do the PCB mounting hole fitment is to make standoffs larger than you need without holes in them and then cut out the hole afterwards in the perfect spot. It doesn't work as well with port holes on the outside of the housing, but you can still alter the surface around the ports to cut them out afterwards, and a good trick with that is to make labels to cover up oversized port holes. You can even make labels out of metal as a flat panel that can be printed and that will be much, much more accurate than the holes on the side of a large housing with complex geometry with all the warping and shrinking that goes on

[@sinformant]

Im going to have to check into that printing service! I resin print and sell a part for cars that i sell for $30 each. I have had a few customers have issues with the parts getting brittle and breaking due to heat exposure under the hood of their car. I contacted a 3d printing service to inquire about having them printed in aluminum or stainless steel and their quote was over $300 for one part and the price really didnt drop ordering multiple parts. The part i sell is small and has about 1/10th the materials that your laptop case uses.

[@linux2420]

I'm currently in the process of designing a "laptop" with a similar idea to this but using standard PC components instead. One of my big concerns was the precision of the metal 3d printing and if my part would arrive slightly smaller or larger than specified, but most of my worries are answered now, This video is an amazing resource to me, not to mention this project is insanely cool!

[@polymatt]

Really glad it helped and best of luck on the project!

[@PixelPipes]

would have liked to see the closed profile, awesome job, it came out great.

[@anon_y_mousse]

This is just awesome. It really makes me want to build my own laptop from scratch. I'm thinking that it'd be easiest to just weld some sheet metal and grind sharp corners. I could even weld nuts and bolts in strategic places to use as standoffs. If I made it really thick like older laptops were, I could maybe solder multiple Pi's together as a cluster and have a giant battery.

[@polymatt]

[@calvinDy]

ITS A CRIME TO NOT SHOW THE BUTTERFLY KEYBOARD WORKING!!! I waited the whole time to see it work with the new case, but alas it never came T_T

[@polymatt]

😂 Check my reels for a fix - although it’s not this laptop, it’s an original.

[@XenonG]

For those wondering if it'll be tough enough to be a weapon, no it won't. Since it's laser layered, it'll likely shatter on shock loads.

[@polymatt]

Next video: drop test? 😄

[@ixin645]

They mentioned cooking it, he did too. Wouldnt that fix it?

[@rkan2]

The cooked parts should be plenty strong compared with the benchmarks like the carbon composites or magnesium bodies.

[@linux2420]

I remember seeing some testing that resulted in, for many loads, 3d printed steel being incredibly comparable and sometimes even stronger than regular steel parts. Probably greatly depends on the type of load, however. As other people mentioned, i think the heating/cooling process would take care of a lot of the brittle-ness

[@XenonG]

@@linux2420 Yeah, I've read about the uses more recently. I also had a brain fart moment when I made the comment, because I knew SpaceX 3D prints the hull of their Starships and had been 3D printing structural and engine parts for Falcon 9 and Heavy :| These hardware go through intense amounts of heat, combined with sustained and shock structural loads then get reused lmao

[@drstefankrank]

How about using an inlay for isolation out of a 3d printer? Just 2 or 3 layers with a low layer height should make a very good fitting inlay without manual cutting labour.

[@polymatt]

That would be a great idea for the top and base but there were a lot of really small edges and connectors I needed to cover all over the place. Maybe building up layers of an acrylic spray? There’s definitely got to be a better way.

[@drstefankrank]

@@polymatt I believe there are isolation sprays especially for electronics, but I wouldn't trust them for this application. Not sure about acrylic. If a sharp pin is moving and rubbing it of, a disaster can strike later. I guess I would have just used some layers of Kapton tape in addition to a printed isolation layer.

[@mrnlce7939]

Could you perhaps have sprayed the interior of the case with a clear polyurethane paint to isolate the case from the pc components? Just curious. Great video. Keep up the good work.

[@polymatt]

Thanks! I thought about it but there are a few sharp parts on the system board that I would be afraid would puncture any thin layer. Another person suggested plasti dip but it’s not very rugged at all - especially with sharp objects.

[@oso2k]

Kapton tape on the inside might have been easier? Or at least a cricut/craft cutter machine to cut your vinyl?

[@dougdirac]

Could we see you open and close the lid at least once?

[@ste76539]

Glad you wore your safety sandals while you were heating up that metal.

[@SpencerHHO]

Low carbon stainless steel shouldn't become particularly brittle from rapid thermal cycling. It work hardens like a mofo if you bend or press it a lot but the grain type doesn't change in a significant way from heating and rapid cooling. You need a bit more carbon than what's present in 316 SS. Austenetic stainless steels tollerance to thermal cycling is a big reason it's used in many situations. I've straightened pieces like that by tacking a corner to a piece of carbon steel, stretching or otherwise forcing it into place, tacking it to hold position and heating the whole thing up. I have a love hate relationship with stainless steel. Getting it to behave how you want is a pain.

[@polymatt]

Really good insight thanks! Wish I had access to a proper metal shop as well. Have you worked with this kind of SLM SS before? I’m assuming it probably has some different properties than traditional stamped/rolled/forged etc.

[@danielgomez2503]

You should try designing more light weight Thinkpad replacement parts and partner with JLPCB to sell them as kits 😀

[@rkan2]

[@jackipiegg]

15:42 You should just use plastic sheet like every PSU ever made. OLD gaming consoles with AC PSU inside has it too, PS2/PS1 has bare PSU inside the console has this sheet perfectly engineered.

[@polymatt]

The issue is that it’s not just the base that I needed to insulate. There was a TON of other small places that touched the case like surrounding the connectors.

[@xer0052]

Great project. Maybe a mix of the properties from both prints would be the best solution, SLS print it in something like nylon?

What's going on on the side of the machine there? Did you cut the sides of the chassis off? I wish there was some 360 b-roll of the finished project. I really dig the brutalist design.

[@polymatt]

Good question - that whole side is for the components: battery HDD and PCMCIA covers. I didn’t have the battery in and chose not to print the other covers in metal because the covers need to bend a bit to lock in.

[@RetroBerner]

@@polymatt Maybe you could spray the plastic parts in metallic spray paint and use them

[@Aikano9]

I’m sure you’ve probably seen some Damascus forging videos from a certain British blacksmith, where he usually dips the finished parts in ferric chloride? Then in baking powder water to neutralize the ferric chloride, and then lets it sit instant coffee to get the Damascus pattern more visible and higher contrast between the colors. I wonder what these metal 3d printed parts would look like if you did the same finishing process. Would there be any discernible pattern? Since these are made with very thin layers stacked on top of each other, I’m thinking it might have a similar appearance to Damascus

[@exturkconner]

The vinyl wrapping of the interior kind of seems like an unnecessarily labor intensive choice. You could have just spray painted a layer of clear coat over the entire inside as a conformal coating. Given that the internals don't move once they are screwed down that would have likely been more than enough.

[@polymatt]

If you’ve seen my videos labor intensive is my middle name :). Definitely not going for efficiency here! Also while screwed in there is still a lot of flex in the system boards and having the keyboard sitting right on top - definitely wasn’t going to take the chance of frying a very special bit of hardware.

[@polymatt]

I did polish the top and it’s very shiny - I can see my reflection in it but it’s not a pure mirror finish as there are lines and artifacts that I wasn’t able to sand or buff out. It’s embedded in the steel so I’m guessing it’s artifacts based on the SLM process.

[@davidoliveira7184]

Awesome project! 👏 Since supply is scarcer and scarcer, what barriers are there to 3D print the *butterfly keyboard* components?

[@polymatt]

Thanks so much! Great question. So the keyboard is a tough one. It's really precise and made from a metal track in hard injection molded plastic. You'd probably have an easier time cutting sheet metal rather than 3D printing the base and the tracks, then you'd have to figure out what you're going to do for keycaps, as this is a rubber dome style keyboard and membrane. It's definitely doable but in my experience, the keyboard almost never fails. If it ever sticks, or doesn't work, its due to an issue with the case or re-assembly pushing up on the bottom since the tolerances are so tight. I've never seen one that's actually broken from use or stress.

I know this was just a fun project for you to learn about metal 3D printing, but I was merely wondering if that would be something you might do later on when you get tired of carrying that weight around.

[@polymatt]

Definitely better for the material selection but you’d have to break up the model into multiple pieces. There are some tricky details, holes and undercuts I don’t believe would be possible even on a 5 axis mill the way that the base of the case is today. If I were to separate out some pieces, definitely doable.

[@rkan2]

Magnesium and magnesium composites are often used in laptops.

[@davidoliveira7184]

Definitely. Now that I know how the case deforms, If i were to do this again, I'd add in temporary internal stiffeners attached to the sides and the base with small (1mm or so) connection points designed to keep the case from warping but intended to be cut off at afterwards.

If you’re genuinely curious I’m happy to answer: to continue with your car analogy, people modding or fixing up old hardware is a lot like people fixing or modding up classic cars. This laptop model is a classic - it’s in the New York Museum of Modern Art. Am I expecting to use this in any modern day tasks? Absolutely not. But do I find it a fun hobby to restore “classics”? Yeah, I do. So to answer your question - SOME computers are about performance. Like the ones I play modern games on and edit this video. But some are a fun and educational hobby where I can learn new skills and contribute to a community of people that are interested in preserving cool historic things.

How can you talk for so long and not show it actually closing even once? i'm disappointed, notv even sure it even works.

[@polymatt]

That’s because it doesn’t. I eluded to the issues with the bottom case and unfortunately the bit where I talk about the fact that the few mm effect of the bowing causes the keyboard to not close fully wasn’t in the final edit. *braces for well deserved ridicule*

did i miss it or did you seriously not fold it down even once??????
