UNW Testing: 3D printed parts with 700PSI of air pressure out of a paintball air tank HPA

the 700PSI is a rough estaminet it could be more or less so long you get that a paintball air tank of 3000 PSI or 4500 PSI. is not literally out putting that pressure into a paintball marker... that would be catastrophic and there are safety valves build in to prevent that from happing.
any ways back to the test. I had a hard time seeing things of find any info about this. but I did see some videos about people making miniature compressed air powered engine motors. so they might use different settings / materials / lower pressures? I mean , to be short about it it did not explode or anything. but it did leak all over the place... but it might be a starting point for some one to see what I did wrong and what could be done differently.
here is a link to a rotary engen that I watched that might be interesting if this is something that intrest you. the use of compressed air and 3D printed parts

A ideia é boa, eu mesmo já pensei em coisas assim, o problema é colocar isso em campo aberto, qualquer força externa pode causar um efeito dominó na peça, caçando partes mais frágeis e as usando para escapar o ar ou até mesmo explodir. Mas é muito bom, você é um dos pouquíssimos canais com um conteúdo interessante e que explora essa coisa de fazer do 0 projetos. Na Alemanha tem um cara que fez um drum mag usando apenas mola, infelizmente ele não envia para o Brasil e creio que seja impossível que ele venda o arquivo.

yeah it was a interesting experiment. but if you can for your projects then it's way better to stay with metal parts on this type of thing. but who knows maybe someone finds out a good way to using 3d printed part for things like this but it will always be weaker. no telling if UV, oil is damaging the plastic over time leaving you with a air leak.

[@FoXHoundPaintball]

Maybe you should try using a Resin printer? Not sure if it would hold together, but it should be more airtight.

[@UntangleWORKS]

that is a possibility I have no idea how that would behave under pressure. I did think at a later time, like well it does work once you are past the the marker regulator and the pressure is lower (400PSI?). since I did made a 3d printed cap/plug to seal of something with in a tipx internals for the FGC68 build that I made, and that works fine.

coating the 3d printed object with superglue or adhesive glue

Пластик... 😕 Пластик из 3D принтеров имеет полости (возможно печатать без пустот внутри пластика?) ...или используй полиэфирная смола для создания эта деталь (используй напечатаную деталь как образец, сделай форму из силикона и залей эпоксидной смолой) * Plastic... Пластик Plastic from 3D printers has cavities (is it possible to print without voids inside the plastic?) ...or use polyester resin to create this part (use the printed part as a sample, make a mold out of silicone and fill it with epoxy resin with reinforcement threads) ...?

[@UntangleWORKS]

yeah, that is idd a thing to look at. it looks like I got some air pockets inside my printed parts, so my extrusion settings don't look to be that great for this. and that about making a mold that could be a way to go as well incase you really need a custom shape like I used in this test. but the complicated part with that is that you need to keep in mind that the part shrinks a bit. not that I'm a experienced in making molds and so on.

@@UntangleWORKS Você já pensou na possibilidade de usar moldes impressos em 3D com filamentos que suportam temperaturas maiores para acopla-las em um pistão e pressionar plástico derretido dentro? Seria uma forma de injeção plástica e assim te dará maior resistência mecânica.

@@JJ_Assalt well I have seen people do something like that. in the sense that they make a molt with a 3d printed part. I think they did it with a resin printer. but for now do I have not really played around with that technic. I have seen some things about it on this YT channel TheCrafsMan SteadyCraftin kzbin.info
