1. Why do they call it a printer?

A replicator ala Star Trek would be more like it IMHO.

Otherwise I find it fascinating. However, will end the need for factories and jobs as we know them?

2. Because it lays down polymers and resin (don't quote me on the polymer) a thin layer at a

 

time.... it actually prints it out.

Your other question.... the factory of the future will have two employees. A man and a dog. The man will be there to watch the switch. The dog will be there to make sure he doesn't touch it.

35. Not true

What's it take to print, say, a wrench? Even assuming we will ever be able to print with metal strong enough for wrenches, it'll take a while.

A conventional forging machine will make hundreds of wrenches in the time it takes to print one.

This technology would end the need to stock millions of parts for cars they don't make anymore; just print a new camshaft for your Corvair instead of stocking a shelf in a warehouse with them. If you need thousands or millions of something, current production methods are better.

57. If I had one of those, I'd already have a wrench

I would like to have one. I would use it in a confectionery business.

Imagine you're getting married and your bride-to-be wants a special, personalized souvenir for her shower. I know...how about chocolate bars with the wedding couple's names on them? She would come to me, I would design her bar, she'd sign off on it and I would make them.

But here's the thing: I would never attempt to print fifty candy bars in chocolate, even though I could. I would print three in plastic, vacuform them in acetyl plastic sheet, and pour tempered chocolate into them.

The same process would work for bars sold at high school games...imagine how many Timberwolf Bars or Viking Bars the local high schools could sell.

I've heard all this before with other things new and technological...oh, online shopping will kill stores. In the end, technology does what it does best and traditional ways do what they do best. The average person wouldn't buy one of these machines. Everything he needs is available commercially. A lot of people who bought one would use it until the novelty wore off. Look in the classifieds of your local paper and you'll find plenty of "used once" items - things people bought because they were going to be so cool, then sold once the cool wore off. The great mass of people are not going to buy an expensive tool to make their own 2010 Dodge Dakota PCV valves when it's quicker and cheaper to buy them at AutoZone.

This is a tool for a limited subset of the population.

The first home users that will buy them are guys who have lathes and table saws. They made all the cabinets in their kitchens. They made the salad bowls. They learned metal spinning and made the skillets. Now they can make their own flatware? Yeah buddy, sign them up!

The Jay Lenos among us will be the other home users. They buy cars whose manufacturers went out of the car business 71 years ago today. There are cars from the fifties that won't run for lack of parts. If the Sunbeam Club or the Bricklin Club had downloadable part files, you could make your own carb floats.

And in industry, prototypes and tooling are natural uses.

But building a factory to print over hours what a hydraulic press can make in seconds? Not likely.

9. Depending on what they are printing, I assume you could change the composition of

the "ink" to be closer to what you want to make to be like the original. Isn't the principle behind the Star Trek replicator that it rearranged the atoms of the waste and trash on the ship?

11. what's really crazy is that our dept core facility manager printed one yesterday...

...as the calibration object for our new 3D printer. Not that big though-- his looked like a six inch wrench. But the crazy thing is that it prints in one piece, with the threads, the knurled adjustment screw, and the rack on the sliding mechanism all pre-assembled in position, with the space filled by a different plastic that dissolves out during a sodium hydroxide soak. The adjustment screw was just beginning to turn when he showed it to me. Way cool.

It used a stabilization material between working parts that needed to be removed by soaking in hot sodium hydroxide (not a very strong soln though, apparently). It was just beginning to loosen up when he showed it to me. The adjustable parts were not actually moving yet, just beginning to wiggle a little.

23. I have a 3D printer at school, allow me to explain:

I also have a couple of small crescent wrenches we printed, they don't work as well as the real thing but are nonetheless amazing.

There are technologies for metal printing, a form of sintering, that costs more than the ABS plastic printers that run from $1,500 to $30,000 and more.

The support material is different from the printing material, and after the entire wrench is printed, you need to take the whole mess, the final parts and support material, and soak it in a hot bath of lye, often attached to the printing unit.

It usually takes overnight to dissolve the support material and sometimes you have to use dental tools to pull the stuff out of cavities, but it does eventually go away.

A better form of printing is stereolithography, I hope to get an SL printer soon. No support material involved.

Here's something I've printed:

I'd be only slightly surprised if there was some kneejerk attempt at an outright ban or mandatory licensing, especially after the first time someone does something particularly stupid with one and the news gets a hold of it.

Of course, at the same time, rolling your own designs is pretty easy for the existing ones, especially if they can already read numerous existing 3D/CAD formats. I imagine there's going to be quite a few companies thinking they can get into business selling schematics for one simple thing or another who will get completely bypassed by what's already publicly available in that department.

Really now, plastic wrenches, how long are those going to last? But hey, they're cheap to make and as the price of these things goes down, more and more people will use them.

Meanwhile by doing so we will continue to burn more and more energy, and cause more and more pollution.

Just go out and buy a good set of metal wrenches, they'll last your lifetime or more.

I remember them. Prohibitively pricy albatrosses, all.

Now I have numerous old (not that old) calculators, cell phones and desktop/laptop computers strewn between old boxes in my garage.

I use a smartphone that can perform the functions of all three...and then some. By a mile.

65. And a thought. A foundry with one of these, could make...

 

Dies on Monday.
Sand moulds Tuesday.
Pour on Wedneday.
Break out and clean up on Thursday.
Deliver on Friday.

Any part ever cast in metal can be cast again. Cheaply enough to make it worthwhile.

67. We had one of these in for a demo

At work. I have to say they are pretty sweet. Expensive and slow as hell. But amazing. Printed out a working salt shaker.

73. Ones that print with ABS plastic aren't that expensive, I don't think

A few here at Amazon for under $1500.

An elegant solution for replacing lost pen caps.

76. When I first saw this on This Old House (post #74) I thought how cool it would be...

... to be able to print a full size home.

Maybe one day a truck will pull up to the job site and print entire sections of a home or components.

Or custom furniture? Maybe all that plastic furniture on the show Space 1999 was printed.

78. Entire rows of homes could be built this way.

Huge versions with many different "print heads", moving on rails.
(saw it on some PBS show several months ago)

edit: this one, I think:

70. Pretty cool

Lurker here. This is really cool, but I don't know how that wrench would hold up in actual field use. I have a breaker bar that I use to break torque on rusted/painted on bolts that my impact won't. It was around $15 and it does a great job. I just don't see actual metal tools being replaced by printed ones.

77. How about,

if you had some old gadget with a few broken or worn parts. With this device you could repair said gadget by "printing" a new part.
Granted, you would need the old part and may need to fix it on screen after scanning it, but the idea is really exciting.
There are things it could not do, like springs or weighty items, but if for example you could infuse electrical paths, wiring so to speak through the part, you could invent new ways of doing manufacturing.
This is only the beginning.
I have seen a few videos on these printers, this one is the best cause it shows more of how it actually works.
Its a crazy world.

79. Wow! I've heard of these printers, but couldn't imagine what they were talking about.

Thanks for posting, 2on2u!

Fascinating.
