This is the result. [imageshack.us]

Technically, 3D printing is VERY cool. Practically, this 3D printing does not produce anything really functional. Let's not oversell.

That was bizarrely random.

First, that's certainly not the best print job even an inexpensive 3d printer can do.

Second, very high fidelity isn't the only metric for utility.

And finally, there are finishing techniques that are useful for aesthetic qualities of a part, if that's something you're concerned with.

It's crucially important to start any potentially positive Linux discussion with a dose of FUD, mockery and denigration. You are NOT going to see Linux portrayed realistically or positively here.

Microsoft, Apple, Facebook, Oracle etc pay Slashdot's bills. Live with it.

Yet another Slashdot article presenting 3D printing. More specifically, homebrew 3D printing. It's been quite the rage on Slashdot lately. Almost, though not quite, as much as Bitcoin stories.

I chose to provide what so many of these stories fail to provide, a picture of the complete product. This particular picture [imageshack.us] comes from the same person that the story was about. On his picture site are pictures of his printer, the PengPad and output for the printer.

The linked picture of printed output clearly shows a crudely finished object made from stacked layers of strings of molten plastic. It is obviously poorly finished, akin to a skilled amateur's wood carving. Upon observing the extensive layering, one cannot escape the conclusion that it has poor strength. Perhaps most damning of all, it is clear that the tolerances of the finished product are very limited and unreliable.

These are all just observations of the finished product from yet another, seemingly over-hyped article on 3D printers. My post was simply intended to ground the hype in a little dose of reality.

  What is bizarre is your butt-hurt post of apparent defense of 3D printers. Apparently, you have a serious problem with anyone that points out that homebrew 3D printers aren't 'all that'. But, if you'd like to provide an actual example of a finished homebrew 3D printed product that disproves my examples, I strongly encourage you to do so. Let me get you started with this, oh so useful, iPhone tripod bracket [amazonaws.com] . Super handy(?). How about something more useful like this lens cap holder. [amazonaws.com]

So far as I can see, my original point remains. 3D printing is very cool, but actual results are of poor quality and questionable use. The reality is not matching the level of hype.

It's quite the rage everywhere, it's just not much in the mainstream news yet. It is truly revolutionary, it's a game changer. Ten years from now we will be looking back incredulously on a time when we had to go to the store to buy most household goods, just as we look back incredulously on record stores and video rental shops now. Yes, some are still around... and there will always be stores for specialty items and things that can't be home-printed, but for a lot of things you will just need to have raw materials stocked.

Don't dismiss it because of the current limitations, i.e. plastics and spray nozzles. The materials, precision and techniques will improve rapidly. Just look at today's 3-D printing as "proof of concept" for tomorrow's typical manufacturing. :)

I'm printing functional prototypes for a new product for work right now on my Makerbot Replicator at home. You can make very functional things with a 3D printer. It's more than strong enough, but not injection molded strong.

But you can make the molds in a 3D printer!

Anonymous Coward | about a year and a half ago | (#43381213)

If you rivetted the printer to a desktop, wouldn't that be just as "stand-alone?

It's not like much manual control is needed. (3, Insightful)

Animats (122034) | about a year and a half ago | (#43381215)

Since there are 3D printers controlled by four buttons and a two-line character display, the touch screen interface doesn't have to do much. Much modern industrial equipment has a touch-screen interface, simply because it's cheaper than building panels full of buttons and dials.

The emergency stop button on industrial machinery is always a physical big red button.

jockm (233372) | about a year and a half ago | (#43381387)

While it is true you don't need more than that, it is very very nice to have more than that. I routingly move the bed and printhead to aid in cleaning the bed (and not always to the same location). I like to raise the Z axis before a print to make sure I get any stray material from the head. There is the big red stop button (which Pronterface really needs to add), and then there is loading and viewing models, interacting with the printer, etc etc etc

We technically don't need a lot of things, but doesn't mean they aren't really nice to have...

Can just imagine the meeting that led to the name:

"It's a printer interface, what do we call it?"
"Printer interface... printerface?"
"Pro printerface, because it is for professionals."
"Pronterface"
"Let's rock"

Don't we just call that a computer? (2)

jockm (233372) | about a year and a half ago | (#43381367)

Don't get me wrong it is very cool, but since the tablet is just running a fairly stock Linux, isn't it really just a computer at that point?

I control my PrintrBot LC with an older model TabletKiosk UMPC [tabletkiosk.com] . It means I don't have to dedicate a more powerful computer to the task, and gives me touchscreen control. And do not discount how useful that is.

I really like the UI customizations and am going to have to do something like that to get the temp display into a more useful location. So I am not saying what he did is uninteresting, far from it. But it isn't that hard of an accomplishment. The software being iOS or Android based and customized to that kind of UI would have been more interesting. To me at least.

Don't you get it? It's teh Linux!!!!1111!!!!!
 
Anything that anyone can lay some amount of claim to being somehow related to something remotely Linux makes the front page of Slashdot. Regardless of the truth behind it or wether or not the fact that Linux was used even matters. I swear, the fanboys around here shit their pants anytime Linux is mentioned and if you happen to show them that a 10 dollar integrated system does everything just as good as a 200 dollar Linux solution they act like there is some reason that Linux was the better choice.
 
It's just another reason I think so many people who I knew who were early adopters of Linux got sick of the culture and left Linux. The single one I still know who has any interest in Linux is a server admin who just passes it off as another tool of his job.

Re:Don't we just call that a computer? (1)

Anonymous Coward | about a year and a half ago | (#43381881)

While I actually like the article, I agree that it's a bit sad what kind of obsession this website has for Linux. It's like having just the Linux kernel at the core somehow automatically makes the whole system a thing to worship.

Heh, you haven't seen any 3D printing worship or private space colonization fever??? This place is filled with people who think that writing a script means something in the physical world...

Control? I want full creation / creativity (1)

WillAdams (45638) | about a year and a half ago | (#43382383)

Where's the elegant, intuitive interface which effortlessly converts a sketch into arcs and lines for G-code output? And I don't mean by faking it as polylines. Best list of software I can find is: http://www.shapeoko.com/wiki/index.php/Advanced_Software [shapeoko.com] and I'm reduced to hand-coding G-code: http://www.shapeoko.com/wiki/index.php/File:Circle-diamond-square-50mm.txt [shapeoko.com] 'cause nothing works well on my Fujitsu Stylistic --- at least it works well for using Grbl controller: http://zapmaker.org/projects/grbl-controller-3-0/ [zapmaker.org] to interface w/ the machine.

I'm hoping I'll be able to grok the Python code in xasy the Asymptote front-end and tweak it into something I find as comfortable as Macromedia Freehand.

http://www.doodle3d.com/ might be a step in the right direction, though it's probably too simplified for you. Personally, I prefer to use openscad, but mostly because I find using a mouse and a 2d screen too cumbersome to change things once drawn (and I guess because I'm more of a programmer than a 3d artist).

Re:Control? I want full creation / creativity (1)

WillAdams (45638) | about a year and a half ago | (#43383919)

To be fair, OpenSCAD runs fine --- it just doesn't allow easy Bezier drawing and I still haven't found a nice CAM package which works well for me on my ancient Fujitsu Stylistic.

The Doodle3D program is interesting --- does one use GNUstep to compile it for Linux or Windows?

There was a thread recently on slashdot about the negative image of "Linux Inside". If you needed any kind of example of why that might be the case, just look at that tablet.

Pengpod? (0)

Anonymous Coward | about a year and a half ago | (#43382663)

I hadn't heard of them until now!

Their tablets and linux USB stick look promising, the A10 notwitstanding.
