Join Deke McClelland for an in-depth discussion in this video 3D printing in Photoshop!, part of Photoshop: 2013 Creative Cloud Updates.
One of the hottest, developments, in the realm of digital design, is 3D printing. Which has application, across all sorts, of disciplines, from engineering, to medical, to prototyping, jewelry. Heck you can even print your next set of sunglasses. Which, is why it's so great ,that version 14.2 of Photoshop CC ,now supports 3-D printing. Now, I'll warn you up front, it's quite a bit more complicated, than 2-D printing. On the plus side, it's more streamlined, in Photoshop than it is in most programs.
And hopefully, this video, will give you a sense, for how it works. You start things off, by selecting a 3-D object, here inside the layers panel, and mine happens to be this model of a bull, that, I got from fellow lynda.com author, Ryan Kiddleson. Next, we want to go to the upper right corner of the screen and switch to the 3D workspace, so that we can see the properties panel and of course, the 3D panel, which is now located, next door to layers.
Now, you want to switch, from environment or whatever, else, is selected, to scene here inside the 3D panel. And then, you'll have this second option in the properties panel, 3D print set, that takes you, to the 3D print settings. So, go ahead and click on it, and you'll see a preview, of your printed 3D object. Now, if you happen to own a 3D printer, then you'd set print to, to local, meaning a local printer, and then you'd set printer, to your model of printer.
Now arguably, the most popular one on the market right now, is the MakerBot Replicator two. And just to give you a sense of what that looks like ,I've got this image, right here ,so you can see, just how large the device is, it only has so much volume, in order to print the object. It starts, by printing it at the bottom and builds it, on up and that will become very important, in just a moment. I'll go ahead and switch back, to my artwork here, and also switch back to my 3D print settings, and now, what I need to do, is specify the size of my physical object.
So, I'll go ahead and set my printer volume, to inches, because, that's, the unit of measure, that, I'm most comfortable with. And now notice, if I go ahead and increase, the height, of my properties panel, that I can see these values, labeled, scene volume and that tells me how big, my bull is actually going to print and you can see, the x value, is more than 33 inches, which is just ginormous and way too big, to fit inside that printer, we saw just a moment ago. So, I need to click on this button right here, scale to print volume, and that's going to make the bull smaller.
And, it doesn't look like it made the bull smaller, it looks like it made, the volume larger. But, it did actually change the size, at which this item is going to to print, as you can see, right here. And, I'm actually going to take it down, a little smaller, I'll go ahead and change, the x value, to, five inches. And the other values, will update accordingly. Now, if you have any surface details, such as bump maps, you might want to leave this check box turned on. In my case, I don't have any, so I'm going to go ahead and turn it off, just to simplify the process. And now notice these check boxes down, here, support structures, including, a raft and scaffolding.
What happens, when you're working, with the three D consumer printer? It's as I say, everything, is built up, from the bottom. And let me show you, what I mean by that. I'll go ahead and switch to the move tool, up, here at the top of the tool box. And I'll switch, to the rotate mode, right there. And i'll go ahead and rotate ,my camera view, so I can better ,see ,what I'm doing. And, notice that the bull here, who has kind of moved out of the frame, a little bit, kind of drag him down, is standing, directly, on top of the ground plane.
So, this would be, the point where the printer, begins ,building up the object. Well ,it's gotta be able to support the object, as it builds it, that's the raft, by the way, and then it needs ways, to arrive at these various pieces, of the object. So, somehow, it needs to build up to this, foot for example, and those vertical supports, that are built upward, that's what's known as the scaffolding and to see, what I mean, by that, you drop down to this little icon right there, start print, and that's how you actually generate ,the print file.
Now, you're going to have to wait a few moments, for the progress bar to go by. Because, Photoshop, is trying to determine, what the raft and scaffolding look like. And now, were actually seeing the bull ,along with the raft, which is this yellow item right here, and the brown scaffolding. Now, they're not going to print, in, these colors ,by the way. They're all going to print in the same color, because, the replicator two supports, just one material at a time. However, I want you to see, what this looks like here. What we're going to do, is ,move in on the object.
So, I'll go ahead and switch to this tool right here, the slide tool. And, then, I'll drag downward, in order to, essentially, zoom in on this object. I also, want to move it up, so I'll switch to the tool next door, the pan tool and I'll go ahead and drag up here. And you can see, these little scaffoldings, they have these little break off ,bars. So, remember when you're a kid and you got those little plastic, assembly pieces? For example, if you were building, a model and they would be hinged on, a structure as well, and then you would just sort of wiggle, them off.
Well, that's what we've got, in this case, as well, with all this scaffolding. And now you go, ahead and click on the export button and you'll get a file. Put, that file in an SDK card, put that SD card into your 3D printer and away you go. Any way, that's, one way to work. I'll cancel, that here, thing is, I don't know about you, but I don't own, a 3D printer. So, for those of us, that are working, without consumer printers, we can take advantage, of, a professional 3D printing service, which is, shapeways.com.
And you can check them out, if you want to. But ,notice, this next item here, now determines, the material. And look how many materials, we have to choose from. So, how in the world are we going to get ,any idea of what we are doing, by looking at this huge list. Well, here's what you want to do, go to shapeways.com and check out their material portfolio, right here, and then you can get an idea of what each one of these looks like. Now, a lot of these items, that you're going to be, drawn to, such as steel and brass and so forth, are very expensive.
Check out, his price right here, $16, per a cubic centimeter. Cubic centimeter, is about as big as the tip of your pinky. You're not getting much, at a time for $16. Where as a lot of these other materials, are, less expensive. Check out, this guy right, here, full color sandstone. That's the only material, that allows you to define colors, just so you're aware. All of the other ones ,are, going to be monochrome. Now, what you probably want to do, is set, your price, to, I'm guessing low, because, this can get very expensive.
And then, set your detail level, presumably, to something like high. And then set your strength, I would think, to high, as well. And you're going to boil, down to one option ,right here, strong and flexible plastic. So, let's go with that, I'll go ahead and switch back to Photoshop and then I'll change this option right there, to white, strong and flexible, which is the last item in the list, and so what that means, is even though, I've set up my bull as if he's made of gold, he's really going to print in plastic.
Now, my scene volume, is, still set to five inches, that's a good thing. I've got my detail level, set to medium, if you want to work high, you can. But, if you do so, then, it's going to take a lot longer, to generate, that print preview. So, I'm going to, stick with medium. And, now notice, we don't need any supports. We don't need that scaffolding or that raft. And that's, because, shapeways is relying on commercial, as opposed, to consumer level, devices. But, other wise, the process is the same. Just, go ahead and drop down to the start print button, click on it, and then you wait for the progress ba,r to go by, which is again, photoshop's way of verifying, your project and making it, print safe ,so that each piece, is going to support, the other piece.
Because otherwise, your 3D printing, can actually physically fall apart. Now, once the progress bar disappears, you'll see this little warning, that says, estimated prices, may differ from final purchase price. And the reason, we're seeing ,that is because ,Photoshop actually, estimates the price of your project for you. And in my case ,you could see, that it's going to, cost about $212. If I don't, want to spend, that much, then, I need to select, a cheaper substance. They do come a little bit cheaper, than, the one I'm using. Or I would need to reduce, my print size and have to make it less that 5 by 5 by ultimately four inches.
In any case, I go ahead and click the export button, and then, I would go to shapeways.com and upload my file. In my case, I'm just going to cancel out, so that I can show you, the final printed, version of the image. And, as I was saying, I don't, have a 3D printer. So, I went ahead and sent my project, to a fellow named, Danierl Persaydo, over at Adobe. And he did me the favor, of outputting, the bull, and it ends up looking like this. And this bull was printed from a consumer level device, which is, why, it has a few little items hanging off, of it there, that are left over from that scaffolding.
And that friends, is my introduction, to the exciting, if complex world, of 3D printing, here in Photoshop CC.
