3D printing and the new economy

i had to come back to add another comment on this. most construction drawings coming out of architects office today, at least major firms, are all required to be drawn in 3D

that's a bit simplified but yes, and the book that Fins was talking about is aware of this happening. should be an interesting read.

for anyone wanting to work in the new economy, that actually isn't new but is evolving ... now is the time to think outside of the box ... way outside of it

Lets say your putting a commode or sink in each cell. You go to a symbols library and insert the already drawn symbols in each unit. People that manufacture doors and windows can give you drawings of their products that you just import from their files into your drawing. You don't have to draw then one by one. If you want to move a wall over say 2' you just click on it and slide it over to it's new location. Years ago entire drawings had to be hand modified. Lets say you want to know how much siding on the side of a structure. Cad has the capability of just clicling on the corners and the Sq. footage is given automatically in any desire unit. What at one time took a room full of drafters can now be done with 1 or 2.

this technology used to be taught at the college level. programming has become so sophisticated, they now can teach the mechanics of 3D printing in middle school and CAD is available at the high school level. all that's left is to build on what already exists.

what you say is true Osmosis. my background is in construction and i have a pretty good knowledge of the architectural field. once they design a school, hospital, correctional facility .. any new designs are just built on a revision of older designs. the concept of "design/build" has been around for quite some time, but now they are able to do it on a much larger scale. the new maximum security prison in raleigh is a good example of it.

The problem with teaching technology is the fact that our school systems can't afford the Cad programs and and 3-d printers. By the time they get it it's like Antithesis said. The technology is too old. Some technology actually eliminates jobs. Once you get it up and running you don't need as many people doing the same thing. The machine does it for you. Once you design something with Cad you never have to draw it again. You can save drawings of parts and sub assemblys and insert them in anything you design that is new. When you modify something you only have to work on the section modified and not the whole structure. I'd say Cad has actually lowered the number of Design jobs since it was created. It's also eliminated a lot of math.

Elmo, are you familiar with the Internet of Goods? It's a key factor in the economic system that economist Jeremy Rifken created called, Zero Marginal Cost Society. He wrote a book explaining his theory that the cost of producing things is going to get so cheap, that they will be free and self sustaining (A good example of his concept is that a 3D printer can make a 3D printer) and it will eventually destroy capitalism it's an interesting theory.


i was totally unaware of the book or this author ... until this morning. thanks so much. i have a nerdy side but not great enough to make sense of it sometimes. i found the book at amazon and will be ordering it today. i read the reviews. the guy might not have all the answers, but i am always intrigued by visionaries.

The education system is having a hard time keeping up with technology. They have to teach students things they will need for jobs that have not been though of, manufacturing things that have not been invented.


This is one of the major flaws in the American education system. We're still teaching kids the answer, instead of teaching them how to think logically so that they can adapt to any situation. With this type of training, they'll understand the current technology once you explain it, but never know how to adapt those skills to the next new concept.

Teaching a kid that 2+2=4 is great, but they need to understand why that's true, not just that it is. And they need to understand why the derivative of h(x) = f(x) + g(x) is (f(x) + g(x))' = f'(x) + g'(x), not just that it is.

3d printing large parts takes time...might be advantageous for intricate items, but mass produced larger parts is the way to go. you could stamp out a fender in like 10-30 seconds from start to finish. my guess on a printer that is cost effective for everyday use would not be able to do it as it needs the area to make a large part(more expensive on the robot), and would have to have a ton of metal powder to drop and fuse to make the fender. Then there is the electric... fusing metal, polishing, for several days wow.. tons of power/money there.

Small parts, plastics, wood, no problem. or you could get a block of metal/wood/plastic and mill it out, lots of time there as well. It definitely has its uses, but large parts is not one...(GE is trying to do airplane engine turbines, but man it takes time)

whoa, information overload. i had to stop and rewind 4 times

china and india have more honor students than we have kids

if it were a country, facebook would be the 3rd largest nation behind india and china

i think i will start thinking in the terms of the very last bit of info, shift happens

thanks for the link. although i will never live to see some of it... i think i am on the right track of at least being a visionary.

train and educate your kids for the jobs that have not even been created yet

you know it Hunter. people have to start being able to think to the very edge of their imagination because that is where the future is.

And further that edge every day. I am past the end of my working career by several years but still try to stay current, attend WCC classes to further my knowledge, read four newspapers every day, and do a lot research on the internet and am still loosing ground.

Watch this seven and one half minute video. It expains what I have been trying to say

It is a fast changing world. No longer is it put part A into hole B in part C. You have to be computer literate to advance in the world. The good old adage, I didn't need an education, why should my child need one? is about as obsolete as the Neanderthal man

thank you GunAtHand, if just one young person in wilkes county can see the benefit of thinking outside the box and put himself/herself on an entirely new path ... i would be thrilled for this thread. don't be left behind.

A teacher friend was talking to me about how interesting it is teaching kids who will use technologies that we have never even dreamed of! So cool!

that might be a way off Bestil, but i bet someone is working on it

a wise person would stop whining about today's economy and prepare for the new one. if you are young, go to college or a technical school and learn CAD. the business opportunities are already out there.

imagine a company that restores old buildings. they need to replace something that is no longer made, but they have a small part of what they want. just scan it, create a 3D image of it, and print it.

what nascar is doing right now is astonishing. they merely give the most precise allowance requirements for a piston or valve and send it off to be printed. machines are so much more precise than humans.

Cool! It's like Star Trek! We have the communicators and now the replicators, next thing you know we can beam ourselves to Paris on Saturday night and be back for church on Sunday!
