Hey! I'm XYZAidan and this is my channel. I make videos experimenting with 3D printing, robotics, electronics, and anything else that pops into my mind.
1. The molds are reusable, and can form multiple times their mass in cardboard 2. The molds don’t have to be 3D printed out of plastic. They could be CNC’d out of any number of materials or created via other means. 3. This video is a loose concept, not a concrete methodology. To take it at face value is to miss the ideas. The “greenness” of this project is in the material’s potential to be substitute for plastic.
I wonder if freeze-drying techniques might yield final-size-as-molded parts? Also, I wonder if any disinfectant / anti-fungal properties need to be added to the material?
I know that this is off topic, but you're very smart. Can you tell everyone the difference in weight of a rolling recycle tote full of dry cardboard (with the lid CLOSED during a rainstorm) vs. the weight of a tote full of wet cardboard because the lid was OPEN during a rainstorm ? I might mention that it's the recycle day today & we're having a rainstorm 😮. Love your videos!
wow i feel like this video was very educational i loved the content the people behind making this video was very amazing thank you for the hard work and research that went into making this video
I've cast recycled newspaper by pressing the pulp into plaster molds without using any glue at all. The end product is only 1/8" thick so it can dry in 24 hours or less if I have a hot sunny day. One downside is the ink which comes off when handling the pulp but fortunately not when the casting is dry. The pulp sticks strongly to nearly every surface. I was shocked that it stuck to glass coated with petroleum jelly. My solution so far has been to coat the mold with a wet paper towel. Oddly enough, once dry the casting can be pulled away from the paper towel. This is not an ideal solution, however. The towel tends to crease in the mold leaving groves in the casted paper. Next, I'll try to soap the mold and then coat it with a wax/turpentine mixture (roughly the same consistency as petroleum jelly). However, in the process I'm currently using, the plaster absorbs a lot of the water from the pulp. If I cover the mold with wax it will probably take much longer to dry. My goal is to cast smooth, highly detailed, thin and strong paper for sculpture.
*I add 1 part 'PLASTIC CEMENT' powder to 25 parts paper-pulp add it's rock solid in 24 hours and water-proof too. Turns out like STONE and has a ceramic "ting" when dropped or handled! I also make Bullet proof plates from tactical vest inserts by adding sand and same extra Cement powder. It can catch a bullet way better then you think since the fiber gets compacted under the singular pressure-point of the bullet and bunches together like a catchers mitt and gets tougher under pressure. The sand and cement behave like a ceramic plate. Best of both worlds. Cost effective for type 1 and 2 armor plates and can even make a type 3 if soaked in sodium silicate for 24 hours and left to air dry for 2 weeks and WAY CHEAPER and lighter than AR500!*
I am not sure about the rice glue, but PVA glue shrinks a bunch when it dries. I wonder if using something like modpodge that shrinks a bunch less would help.
It seems you've moved on from this channel, which is a shame. I would love to see you revisit this idea using the mixed PLA/Plaster of Paris mold designs of @ShakeTheFuture for his printable microwave metal casting molds in the video "Print-Wave Metal Casting: A Different Approach to Metal melting". One side issue with your compression molds is that they require a rather serious infill, which will require more filament in order to repeatably produce molded forms. Replacing some or all of the infill with compressively-resistant plaster might reduce mold production costs and make mold pieces that last longer. I would love to find out whether these ideas are compatible.
Curious if you'd thought of revisiting this project, but using pykrete? Combined with some of the passing cooling paints from @Nighthawkinlight , you could design a summertime igloo which might last for weeks.
This is very similar to my machine, except that mine is a small automatic machine. It is included in the works I published. If you are interested, you can take a look.
I think I'm going to try to make the 3D printed model of what I want, cast the mold out of concrete or plaster and use my hydraulic press. Thanks, good idea!
I need to know how companies make Eco flex soft material and where they get it from how do they get it from the earth I want to be able to make it my self.
I've been researching papercraft toy guns recently. Wonder if those parts could be molded out of scraps and rice this way instead of piles of craft cardboard and superglue.
