After a catered TechShop event, I was inspired by the uneaten crackers, cookies, brownies, vegetables etc.
Here's how you can do the same!
Step 1: Your Materials
And most importantly: Don't rule out a particular food because you think it won't work!
I used these platters of catered food:
and some inspiration from Makezine: http://blog.makezine.com/2007/08/30/how-to-laser-cut-and-cook/
Step 2: Your Tools
The machine I used is an Epilog Helix 45W CO2 Laser which can cut designs up to 24"x18".

Step 3: The Cutting Process
1. Place your food on a plate or piece of paper
2. Consider DPI, speed, and pressure carefully! I played around with it to get the right setting.
(for cheddar cheese I based by settings off of laser-etched chocolate: 300DPI, 30% power, 100% speed)
3. Scale of your image- make sure to adjust your print settings when you switch food!
4. Alignment so your graphic fits nicely
5. Timing and refrigeration...because nobody likes expired, inedible leftovers
Step 4: Admire Your Work
