I've always had an idle curiosity in how to make something like this. Seems like a good way to make custom packaging for products similar to vaccum forming, but with a more environmentally friendly end product. Love it!
Brilliant video (and very cool nails on the third hand!) - I have done pulp sculptures before but it did not even occur to me to make structures like this - next summer I’ll try that!! (Lack of a workshop means working in the yard…)
Eric, we had a part to thermoform for the defence dept a few years back and we lined it with pulp. What we did in the joints is just use a needle and thread to hold them together for soldering., worl extremely well.
Oh come on! this topic is way to exciting (not enough and elaborate videos on it as this one) to have patience to keep waiting for videos :( I love 'em! keep them coming!
I work at the Argentine company in Ushuaia "Pulpak" We make molded pulp products for electronics and our molds are 3D printed. We even recycle our molds to make filament again! It is a very interesting and challenging development especially at a massive industrial level! 45k pads per day!!!!!
Thank you for such a great video. I am going to try and 3d print my screen form in PLA. I am working on building a large shallow ice cube-like tray to hold Lego minifigures. The pulm mold trays will be around 190x140x20. Each tray will hold 4x4 grid of minifigures.
I want to thank you very much for creating this video. I have designed something in my head for over a year and I have not been able to find somebody that walked through the process just like I was hoping for. I am making some cups to hold assortments of Lego. My cups will be 90 mm by 90 mm by 30 mm high. They will have a 5° tapered side and a 10 mm radius on the bottom and edges. I want to make about a thousand of these over the next year for my own personal use. Your video on how to stitch the screen together was great. I liked your demeanor and how you produce the video the calmness of your voice. Great job bravo. Look forward to sending you pictures of my design. Have a great day Merry Christmas
I think Egg crates are made by using a vacuum pump to suck paper slurry into the molds... that may how they get thicker layers of pulp than say paper in a deckle.
I think you could have just pressed the full brass sheet into the mold? I've done it several times in silver mesh using a hydraulic press and some rubber cushioning, but at that gauge, maybe just use the clamps? Might be worth a try. No soldering required.
@@EricStrebel I should have know you tried it! Haha. Brass is a bit finicky. Annealed copper might work, but it depends on so many factors. Thanks for the videos! They are great!
Back in the day I was trying to use paperpulp to mass produce heraldic sheilds with designs on them. I made plaster-of-paris, negative molds, open without a 'push' mold. The plaster wouldn't absorb the moisture due to my vaseline release agent. Yes, drying was very slow and from the back, so the smooth front surface wasn't always dry enough when de-molding. In short, a nightmare - I knew nothing [pre-google] about paper molding. You have me intrigued now, about the industrial method of doing this. One question, do they use two part press molds to make the wire mold as a one-piece?
Yesterday I was thinking about you Eric, when I was fixing an East German chess computer (video on my channel). I had some buttons that were broken, and my initial reaction was... Bugger I have to cast new once. But it's a complex shape with holes etc.. How would Erik do that?! It was in my opinion not a two part mold but perhaps a 3 part. Luckily I found a different solutions to mend them.
We had a Fiber Arts department at my university. I spent an evening in the paper making studio learning how to make custom paper from pulp with one of my fellow art students. It’s a fascinating process and relatively straightforward. She actually used dried citrus fruits (orange and lemon peels) and ground them into the pulp. It makes for some fragrant paper! Question: do you think the issue with the lower powered blender might be resolved by first soaking the shredded cardboard in a bucket of water for a few hours (or overnight maybe)? I’d like to try making some custom RC body shells using this method but I’d like to avoid buying a fancy blender if possible. Also, I’m thinking of working with paper from our paper shredder rather than cardboard. What do you think - is the Ninja blender essential? Thanks.
This does appear to be very labour intensive. I can't help wondering if one could put enough small drain holes in a #D printed mold to achieve a approximation of the sme end result.
Have you seen the pulp molding process that other people have done with 3D printed molds? (the pulp goes right into the printed mold, with no brass screen and it has a smooth finish all the way around). -- It would be need to get your take on the pros/cons of the various approaches here.
I still don't get why you have to dry it up completly in the mold. I've seen several videos where they unmold before it's completly dried up. Are you trying to avoid shrinking ? Also, I,m not convinced by your close up of the egg pack surface texture. It's definitly not the pattern of a metal mesh. It is actually a surface.s pattern designed to ease unmolding. Love your channel BTW.
I throw away my wireless chargers every couple of days. It's about time someone starts making them out of paper pulp. Yes, I'm joking. I love the video but a wireless charger seems like an odd choice for a paper pulp product. I'm looking forward to the next video. Thanks for sharing your techniques with us.

Yup

Great video. This project is so cool, very unique and "green." Can't wait to see the finished project. Mahalo for sharing! : )

paper pulp is a really fun material to work with! and can look quite good still as well. great video :)
Some great techniques here, thanks!

Wow, would it be possible to see a picture of the molds, I am very curious to see that. Can you dm them to me on Instagram?
Next I'd like to see an attempt to 3-d print the mesh. That'd be pretty sweet if it worked.
Possibly, not sure if you could get it fine enough, but it could possibly work
Maybe one of the newer mono 4K resin printers could resolve a fine mesh.

An idea if your soldering iron doesn't have the grunt to hack soldering to the mesh is one of those kitchen blowtorches.
Yup, that will work!

Was not successful in my tests

Yes, there is a second half of the mold often that hold the part when it is ejected from the main mold

The Ninja is essential if you want to actually pulp the paper
This does appear to be very labour intensive. I can't help wondering if one could put enough small drain holes in a #D printed mold to achieve a approximation of the sme end result.

Great intro!
Thanks!
why not just model in a thousand holes in the 3d printed part?
I was wondering about this too, could you use some form of printed holes, or perhaps milled (or drill press drilled...) holes for a similar effect?
Now you are cooking with gas!
That was fascinating 💪
Lol

I was thinking it could possibly be a fire hazard.
