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.

Fri Dec 7, 2012, 05:15 PM
Dec 2012

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.

...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.

Thu Dec 6, 2012, 10:59 PM
Dec 2012

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.

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

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.
