Pure Decadence - Laser Etched Chocolate Bar

after seeing the Laser Etched Powerbook project i got to thinking - i don't use a mac, and isn't there something a bit more temporal i could do? we were breaking out the saturday night munchies and i had an idea...

Step 1: Unwrap chocolate bar

buy a quality chocolate bar, and unwrap it. do not eat yet!

Step 2: Place Chocolate Bar in Laser Cutter

Align carefully and size your graphic to fit the bar.

Put a piece of clean paper under the bar, so that burned plastic from other projects doesn't get on the bottom of the bar. you're going to be eating this!

Step 4: Done

after the etching success i tried to cut all the way through the chocolate with the laser. i was hoping to cut some Escher tilings with different color chocolates. unfortunately the chocolate is much too melty, trying to cut all the way through just made a big puddle of melted chocolate iwhich dribbled all over the laser cutter.

Step 5: Don't have a laser cutter? No problem!

if you're hoping to do this at home and don't have a laser cutter - don't worry! you can easily do this with a piece of cardboard, a sharp knife, and a lamp. just cut the cardboard into a stencil of the pattern you want, then hold the cardboard between the chocolate and the hot lamp. the chocolate will melt in the exposed areas, leaving a very visible pattern even after it cools.

Wow. I wish I had a laser cutter. How many tries did it take to get that bar?
dan (author)  alceste8 years ago
first try, but it was close - i found it in the 'baking' isle and picked it up, but then while transferring to my shopping cart i was distracted by a cutie looking at the brown sugar and almost dropped it!

Where do all your crazy kooks get your laser cutters? I suppose this one is owned by squid labs? I've tried and tried to convince my main squeeze that we need one, but then he hasn't gotten me a sandblaster either. Suppose I better work on getting a couch first. Really, though. Is there an artist's coop or something in the bay area that has one open for use?
any local hackerspaces?
dan (author)  cookiedough7 years ago
not that i know of, but possibly Techshop in palo alto has one.

Just the other day at work we were talking about "branding" images into steaks (raw meat, pre-cooking). A coworker of mine did it a few years back. Pretty similar in concept.

oh yeah? just yesterday we were talking about "branding" images onto people (live, with skin). My coworker gave it a try.

Funny you should say that...

I found this
Who?
Where does the extra little chocolate flakes go? I don't want to waste any yummy chocolate. :(
I think you could cut through it if you put it in freezer for a couple of hours before doing it. Then simply put a piece of acrylic or wood under it.

This method was already patented in Japan on o7 Mar 2006 and the USA patent was also applied based on PCT/JP2007/054763. So, commercial operation with this technology is prohibited. If necessary, reply me. It is available to transfer or lend the right in the USA.

I found that you can also laser engrave polished stone, or even flat cut pieces of stone.

I have an Epilog. I plan to try cookies. I suspect that ones with a plain top like Vanilla wafers would work better than say chocolate chips.

You could turn a chocolate bar into a greeting that with this idea!

what type of Epilog laser cutter do you have? How much was it?

OOOOOHHHHHH! I think I have a small CO2 Laser that is very underpowered at the moment. Im going to try and power it up a little and focus the beam better. Does anyone know if those CO2 lasers have a maximum voltage or amperage rating?
Just realized that it is a Neon - Helium (or something like that). Can one of these lasers cut, melt, do any sort of damage to something?

I thought of this immediately after I saw the laser etching contest but wow it's been done already and it was posted more than a year ago, sweetness!

They own the lazer cutter ;-) For cutting through the chocolate, why not try doing it a few times?
dan (author)  zachninme7 years ago
i tried it, it doesn't work because the chocolate is too melty, it just flows back into the groove. you can get through it eventually but it's a big mess.
I spelt laser with a "z". Wheres my coffee?

Wait-- where is this laser cutter? Do they have one at the TAP Plastics down on South Van Ness?

I haven't tested any of this, but I think the chocolate might hold up better during either process if you put it in the freezer first.

didnt they brand the image of Jesus on a mcmuffin or something?

That's cool, we did that too when we got our laser 9 years ago (Universal 25w). It was fun to try all the things it could do. The joke here was: "Can you do tattoos? Yeah, as soon as I figure out a clamp that will keep people from moving!"
