Is  Quantum Apostrophe dead?  Didn't he get the Bat Signal that there was a new 3D printer thread?

bobtheallmighty: are you trying to say that running a few motors to print paste is going to take more energy then an electric stove?


Yeah. Firstly the front-end costs are much higher: A 3D printer will have electronics parts for the computer inside it, as well as some printer parts I don't know much about, all of which have high design/develop/test/manufacture/maintain costs. An electric stove is just a big resistor coil with some other parts to make it easier to use and better looking. NG/kerosene/propane/butane/whatever fuel stoves are just nozzles and sparkers (with some other parts to make it easier to use and better looking).

Secondly after you've powered the 3D printer you still have to cook the slop you've printed out, so that step costs as much as manufacturing and then running the whole stove/oven you have now.

the printer will likey take less metal then a full stove, TFA also says its will cook things as it prints them (atleast the pizza it talks about) some of the food that comes out is probibly even ready to eat.

the computer parts dont need to be top of the line, its a printer not a super computer, you could likely run it off some pretty underpowered harware. probibly even a cell phone...

I predict that 3D printed food will be as revolutionary as 3D printed guns. Because why make things unless you're doing it from powder and glue?

/It's farking powder and glue, people. It doesn't actually make useful things, it just glues powder together in the SHAPE of things.

IdBeCrazyIf: You know, I think that is like an admirable goal and everything but really we could end world hunger overnight if we just stopped throwing away almost farking half the food we produce

But it's the latest craze that's sweeping the nation!

This?: When we were doing this book, we visited a cricket ranch in Southern California, in Visalia, and the owner told us that he had a beetle infestation and they sprayed some pesticides around the foundation of his huge cricket ranch. And the next morning all the crickets inside were dead. So things really, really happen quickly on a small or large scale.


Yeah that's the one.

I 3D print food every day. It's called cooking.

 

BMFPitt: What is the benefit of this, since we'll still need to bring the raw materials and it won't reduce weight?

Whatever food gets printed is going to be non-perishable type stuff anyway.



This.

PC LOAD BUTTER! WTF does that mean?!

You know how I know you don't know what "additive manufacturing" actually entails? It builds up 3D constructions, layer by layer, out of a powdered aggregate, held together by an adhesive. That aggregate might be sintered metal, but it's still just powder. No. Tensile. Strength. Even if you had a 3D printer that WELDED metal powder together (which you don't), it's still going to be weaker than a liquid-metal casting, and WAY weaker than something forged from steel or built up from a woven fabric.such as carbon fiber.

If the foodomat is loaded with the right atoms, it'll whizzbang out a ribeye faster than you can say johnnycakes, fresh as the day it was printed and cooked perfectly, and that's just swell for astro-men working far out in our solar system. Jolly good for you, spacemen of the FUTURE!

Just like all our space endeavors, we trade extremely high energy inputs here on Earth to create things for space. This is refining foodstuffs to simple building blocks, not unlike what we do with rocket fuel, with the added benefit of greater shelf life and variety for the consumer. What may seem appalling to us is much more appealing to someone facing starvation...

This guy's ultimate plan doesn't really pan out, except in terms of recycling; if we assume we continue to waste a large percentage of our food, then processing wasted food to extract the powders adds efficiency to the consumption curve, albeit with the addition of energy. Maybe this will turn out to be efficient, maybe not... but it is a novel solution to a real problem and possibly part of a future solution to long term food availability issues. If it can be efficient and useful, then we'll figure out how to make that happen.

Why not just re-hydrate and eat the powders? Why do you have to "print" them into something like a pizza? Seems like a waste of energy and space to go through all that trouble when the purpose of eating is for nutrition.

Robinette Broadhead approves.

Except that isn't true - in the majority of 3d printers there is no separate adhesive; the only material used is a spool of plastic which is heated until liquid. The most popular alternatives use light or UV cured resin. Describing it as "powder and glue"demonstrates an astonishing degree of ignorance.

You're acting like such a know-it-all dick in this thread and you don't actually seem to know anything about the topic. That isn't actually a rarity for fark, but it's always amusing to see.

Because there is more to eating than nutrition.

One thing NASA has learned is that morale in spaceflight is strongly affected by food quality.

It's one thing to eat gloop that tastes like cardboard on rare occasion because you must, but having that be your sole food source for days, weeks, or months or years?

Yeah, you try living on dehydrated nutrient powder for months or years crammed into a small capsule, seeing the same people day after day, ect.
