Step 10: Mark the Center With Guides

Now create two guides that bisect the postcard shape for both the horizontal and vertical.

Huzzah! There's the center, ready and waiting.
Doesn't it smell really bad??
depends on the type of acrylic - extruded acrylic (which is mostly used for its ability to get a smoother, more flame-finished laser cut) smells like DEATH, imho. do not want. ...while cast acrylic (which, though more expensive, is always my preference, as you can get a more refined/even looking raster engraving, and still a decent looking cut) has a sweet smell when lasered, similar to the candy-like bouquet wafting through a nail salon. always good to have a nice filtration setup though, so you're not stuck in an acrylic fume-cloud all day.
Awesome Instructable, now all I need is to convince my dad I need a Laser Cutter well Good Luck to me!!
Step 11, Optical Illusion Alert!
I understand etching is much slower then the cutting setting. And how long does it take to etch per block?
you could also combine it with the IKEA Window Postcard
I'm just curious as to how the piece handled the shipping rigors. Did it get chipped up, scratched, cracked? It looks great in the photos but I'd be curious to see how it looked when it arrived at the destination. Finally, you should start a cottage biz making desk placards like this. I would sooooooo pay for one of these.
They all came out in near pristine condition. It was really odd. If I had my own laser cutter, I'd likely make more stuff to sell, but as it is I just use the one at Squid Labs when I can.
Very nice! I really like that clean look!
That's great. It also makes me wonder how it would look if it were colored. Maybe make the top spiral red and the bottom white, or whatever colors you like. I'm not really sure how this could be done, because etching wouldn't work. Does anyone know of a translucent dye that might do the job?
Hey, it's very cool. But I'm reminded of the old Steve Martin joke: &quot;How <em>you</em> can make a million dollars and never pay taxes! First, get a million dollars....&quot; <br/>What do you have to do to laser cut acyrlic? And how do you etch it? If you want to be really helpful, you gotta turn loose of more information. Otherwise, you're just showing off. (A cool thing to show off, mind you, but still just showing off.)<br/>Moorloch<br/>
Etching acrylic, can you not just buy some etching spray? In the UK it's sold in DIY stores, make a template out of card, after all most modern printers are accurate to 5760x1440dpi or more. Then use that as a mask? Just because you don't have all of the fancy kit, doesn't mean you can't do it a slightly more labour intensive manner. Not to say that I wouldn't mind a free Laser cutter.
Isn't etching spray for glass? I've read that if you dilute acetone in methanol you can frost it, but neither one will work for a design with so many tiny curves as this one. I'd suggest finding a way to transfer the images onto the acrylic. That way you can even use color.
I disagree about just showing off. The goal is to explore how to create two layers that can come together when looking at it in the right way. Would I take the time to post 15 steps to show you how to create the layers from scratch if I was just showing off? No, I'd just post a photo and be done with it. Am I showing off that I have a copy of Illustrator as well? Not to point out the obvious or anything, but to laser cut acrylic you'll need a laser cutter. They run about $15,000 and I'm fortunate enough to get time on one and I know that's rare. If you have access to one of those, then the rest is obvious. I've touched upon the subject many times before and didn't feel like repeating it again. I should copy and paste some previous text and put that in here. If you don't have a laser cutter you can take the same ideas and print the results onto transparencies and then glue them to a piece of acrylic you can cut with some cheap and accessible tools.
So how did you stick the postage on?
Sticky side down.
That is incredible. I simply don't have to words to express what an awesome project this is. You have some lucky friends.
Thanks. They have all my best stuff. The only pieces I still have are the mess-ups and prototypes.
i'm new here, so i have a basic question...the illustrator stuff i get, but buying the acrylic piece(where?) and laser cutting(how, with what?) is the stuff I don't get. plus, was there limitations or issues with posting it as a "postcard?" thanks, newb ps. i'll try to look at your previous job and maybe that'll answer me questionns.
Added info on materials and tools to Intro. Technically, it's not a postcard since it's not printed on card stock. The definition I've been given at post offices is a letter or even a large letter or maybe a flat package. It varies, but I always pay whatever's necessary to get it through.
