what would you say if i told you you could have a functioning 100% polymer p90 that could last approximately 10000 shots based on physical tests with new material science advancements for $100?
>>29443077
id be skeptical. the price point especially
That you're a liar.
Almost all of the PS90 is polymer already so it's not unfathomable, but the springs, bolt, barrel, etc cannot be replaced with a composite for $100.

I like my hands attatched to my body, thanks

I'd say provide proof of concept first.
I'd wonder what I would get for $500.
What would you say if I told you OP is a faggot?

OK I am interested. What's the catch? 3d printing? Are you making them?
>>29443229
id say ask op
>>29443077
its airshit isnt it?
The real gun costs around 1500 new and will not blow up after 1000 rounds.

When you make a magazine the length of a ps90 and apply polymer coating to the casing to feed properly

I'd say it's a dubious proposition, at best.
>>29443126
That 3d printer is actually one of the best. Its accurate up to some microns and is 1600 bucks.
>>29443502
P90 in .38 special when
>>29443277
But you could buy 15 plastic ones for that much and then they would, collectively last 150000 shots
>>29443502
Arent there polymers now that are steel tier? Or at least close?
The atf would have a stroke
>>29443608
And?
>>29443162
This. I'd rather have one rifle that can last 1 million rounds than 100 that can last 10000. Make the wear parts out of the best material and save the polymer for the rest until it becomes as good or better than steel for barrels and such.
>>29443593
They're making better and stronger polymers now. It's possible we could see something like that in the future.
But there's no way in hell you could get something like that now, and definitely not for 100 bucks.
>>29443593
Not cheap 3D printable ones.
that fuckin thing would be like at least $350 in printer material, so I'd say you're full of shit.

>a new age of Saturday night specials
>>29443077
I would say that it gives the poor more options when buying a gun for self defense. Its the same principle as people who buy hi points or whatever and just leave them in a drawer as insurance.
>>29443593
Steel and polymer have very different properties and behave very differently. I'm no engineer, but even I understand you can't swap out one material for another purely based on tensile strength.
>>29443796
What are you talking anout? That was made with a single 20 sollar spindle.
>>29443077
I would say you have a poorly made automatic firearm that will almost certainly not last one-tenth as long as you are boasting.
Might as well just buy a pellet gun, or save up a bit for a surplus Nagant; that way there is certainty the fucking thing will work.
>>29443362
isn't 10mm straight walled enough to avoid feeding issues from a straight magazine?
>>29443593
I think barrels are more concerned about melting temperatures
>>29443077
I'd buy one and shoot 10k rounds through it with a string and see what happens when it stops working and when exactly it stops working.

3d printed for 100usd worth of polymer
Lel no
the only 3d printed guns you can make for that kind of money (aside from the 3K$ for the 3d printing machine plus computer and software) are break action low powered pistols (.380, .38sp wad, .45lc cowboy action, 22lr and the like
now making a new body kit for an already barreled P90/PS90 is doable, yet not for 100$ worth of polymer.
>>29443112
Well, he said shoot, never said accuracy.
The chance the bullet would blow out the side is small, but it would rip out the riflings within 10 rounds.
>>29443957
maybe with some faggot shit makerbot that can't print worth a damn. a printer worth a damn is gonna cost about $350 for a canister.
>>29443077
anyone know where I can get 3D CAD files for guns like UZI, MP5 & Beretta PM12?
Believe it when I shoot it
>>29443593
They're still shit at dealing with high temperatures, and you're not going to get steel tier polymers from a cheap 3d printer.
Nice meme
>>29446286
>>29446188
you can get a kilo of polymer for about $5 from certain companies if you get it in bulk.

a p90 in .30 carbine
guys what about this.
you print the parts and then use it to form a sand cast for steel ones. thoughts?
>>29448176
> prefering a shitty casting over shitty plastic
I´ll take the plastic one
>>29448460
why? wouldn't a casting be more durable? aren't most recievers cast?
>>29443077
horseshit
>>29447397
Are you suggesting the most precise one of the bunch can be had for well under the cost of the others?
>>29448599
how is it a suggestion if it's right on their main page?
>>29446352
I mean it's not that they are shit with those temps, it's that filament fed 3d printers print with ABS which is a thermo plastic, which means it shrinks when it cools and expands when it heats. it's designed for injection molding where hot plastic goes into a steel mold and then shrinks and can fall out.
>>29447397
SLA printers are even better.
>>29448176
I mean that's normal, you probably still need to turn it though because burs.
>>29448602
The differences are in the type of materials it can handle and the size of the item you want to print. The one on the right has a printING platform the size of like a medium pizza
>>29448712
SLA is harder to work with and it's more expensive. the resins alone would be 100 bucks per liter. you can get 1kg spindles for 20 bucks. and at 50 microns they aren't THAT much better. the Form 2 is 25 microns, which is just half, yet it costs double, and you have to avoid UV light hitting the chamber, and you have to make support structures.
>>29448882
it goes all the way up vertically though.
>>29448882
i mean yeah yo could work with a lot of different materials but PLA fulfills a lot of requirements for molds and prototyping. i don't do 3d printing but i think it's a nice place to start at 1700. the others are super pricy in comparison even if they do allow you to build higher dimensions, and it's not like you can't slice your model so that you can assemble it.
>>29443077
When it comes to applied sciences and you see asian language, its safe if its korean or japs but if its chinese or anywhere else, you'll lose limbs
>>29449015
well technically it's a collab between japan and taiwan, so it's not super chink tier per se. i think the feeding head is titanium also. chinks would never dare spend that much.

you must be that same dude who said it's impossible to make a full auto sear because you need a million dollar CNC machine and 50 years of engineering experience.
>>29443077
honestly, I wouldn't even care about the firearms considerations...
if you can make a polymer p90 that's 100% polymer, then you've just told me, assuming a factor of safety of 2, that you've made plastic that can withstand ~100,000psi without bursting.
so tell me anon, what else can you magic plastic do?

>First and foremost, the all-metal structure, made from titanium and hard stainless steel, allows for fast heating up to 500°C. Whereas many common hotends max out at around 300°C and are therefore limited to processing PLA or ABS, the DyzEND-X can 3D print with just about any plastic filament on the market, including abrasive (e.g. carbon fiber reinforced) and flexible materials (e.g. Ninjaflex).
>carbon fiber p90
thoughts?
>>29449434

>>29449449
>carbon fiber
>structural firearm components
>>29449505
it only goes down to 200 microns anyway. the printer in the original pic goes down to 50, but it only handles PLA at 200 celsius. the carbon fiber stuff would probably need to go hotter. i wonder if the OEM head can adjust in temperature. probably not advisable but still. it would be interesting.
>>29449505
here are the parts you could print with it if you were willing to stick to only 200 micron precision.
Carbon Fiber
HSHT Fiberglass
Fiberglass
Kevlar
would any of these work for a gun?
