The main thing is positioning in order to reduce wasted space as much as possible. As someone with a 3D printer, I have a teensy bit of an idea on how to position “ready-made” to maximize space. I certainly cannot print/replicate a fully mounted car frame in a single cubic meter, but I can print parts of the frame in such a way that I can mount them like legos, if each rod is 5x5x99cm, I can fit roughly 361 (19x19, with a bit of space between them so they don’t come fused) in the cubic meter. Is that enough to make the whole frame? No idea.

Also, think about it, 1 cubic meter of sandwiches, tacos, pizza and other junk food tasting great AND being perfectly healthy. Damn, now I’m hungry.

I’d never have to quit drugs! Woohoo

I’d say that society as we know it would collapse fairly quickly, with it being replaced by a communist or socialist system fairly quickly. Fields that require brains would be in significant demand, as food would become a non issue. Same thing would occur with other essentials, such as food and medicine. As mentioned in other comments, money would become worthless. And there would be people who would make new replicators who would have reverse engineered their replicators.

Solid cube of antimatter. Fuck you world!

First I’m gonna move out of my apartment since there will sure be plenty of geniuses who’s gonna produce 1 cubic meter of solid gold, and the building might not be happy about 20-ton blocks appearing out of thin air.

I suspect a lot of guns, explosives, body armor and anti-armor munitions due to the immediate civil war that would break out in most countries as the wealthy elite tells the government to confiscate everyones matter replicators.

You mean after gold and diamonds essentially become worthless? A lot of people would definitely use it for medications.

Weed, alcohol, opiates, nicotine.

Let’s be honest, it’ll be nothing but dildos and fleshlights for the first year and a half. We’ll be swimming in life-like toy dicks before anyone realizes we can do anything else with it.

Obviously everybody now has high end computers, cameras, a variety of lenses, phones, etc. Foldable Ebikes like the aipas would fit in the space.

1 meter solar panels are a hit but since most batteries and capacitors require materials difficult to handle it becomes highly demanded.

Every political building now has thick blastproof exteriors as making bombs has never been easier, judges live in the courthouse now.

I’d make my own studio ghibli paintings.

I can fit me in about that space, so maybe a copy of myself. We could trade off working and playing. That would double my leasure time.

I’d replicate some of these new graphics cards that are so hard to find.

Replicate the replicator. Next day, use both to replicate replicators. Repeat ad nauseam.

Clean up the streets, feed garbage into the replicator to be used as fuel/raw materials
