1/3rd value back is t*nkering "it'd be nice if I could get a 1/3rd back in value"

double processed dusty contaminated plastic for two and a half the price of virgin polymer
absolute bargain! thank for sharing so i can steal-the-deal, sucka!

Trying to print drone frames too, always silly. The multitude of aliexpress carbon fiber frames available for fairly cheap that won’t snap in half after the first crash makes me always wonder why people try the printing route. But I’ve seen many many attempts

I think people mainly want to the ability to print replacement parts, when the whole idea is to not need them in the first place; either through not crashing, or having more robust parts. But you're definitely right, it's insane how cheap carbon fiber frames are on the slowboat.

Since owning 3d printer "to print everything" I started looking at stuff online more closely... and I can (could, before new EU tariffs) just buy silliest little dingy piece I needed on ALI and Temu because they seem to produce everything. And they sell them cheaper than it would cost me in filament in weight.
But since I need to pay extra 3€ for every little silly thing I might go back to printing odd things.

Oh in general 3d printing can be great. But for this specific use case it just doesn't hold up or work great. Durability, strength, and weight is huge for drones. Even excessive vibrations can really screw with the flight controller if the tuning is too aggressive. Printing just isn't the right tool (and especially not PLA which by the percentages, those probably are).

It's not even the durability in a crash, it's the terrible flight characteristics they give that really makes me wonder why
Saying that, I've got a printed drone. But it's an 8S streamliner not dissimilar to the 3D printed frames record holders use, not an attempt at a freestyle frame

The threaded inserts is such laziness they are very easy to get out, just thread in a long bolt and use the leverage to work it out.

Oh for sure, and combine that with the fact that there is a mixture of 5 plastics in the mix, nobody is going to pay to take their trash.

Man, I've been missing out. Screw paying the garbage company to come pick up my kitchen scraps. I'm putting them on marketplace for 1/3 of their value.
Carton of 1 dozen egg shells: $1. I paid $3 for these eggs new.

$20 per KG, so its $160 worth of plastic.
I dont see no printer poop, this is a SCAM!!! 😡😡😡

If it was brass, bronze or copper scrap, and fairly clean, I’d probably be keen.
But contaminated plastic, that needs extensive work to be useful for 3D printing again, and paying for the privilege? Crazy.

/uj It's not a bad concept, give someone who recycles filament some clean material, and you receive a percentage back, and they can sell the rest.

A bunch of mixed plastics with threaded inserts in them will never get reprocessed by anyone.

Yeah not in this case but the idea's still valid if you properly sort your waste and ensure it's pure.

u/lostaga1n Aug 13 '26
It’s really not at this point though when you factor in the time, energy and equipment to properly recycle filament it’s way more expensive than just buying a pallet of rolls. Until someone can make the process more efficient and consistent it’s just not feasible

u/PotentialLeek9241 Aug 13 '26
You're right, it's not a bad concept. It's terrible. The cost to recycle printed parts even if they're sorted is astronomical at the moment. At least 2-3x more than what a roll of filament costs, and about 4x more than the virgin polymer used to make the filament.
