Introduction: Real Laser Engraved Egg,

About: I'm an A-level student from the England studying product design and doing a range of part time projects. I also have a laser cutter and laser engraving business called Phoenix Engravers.

*Please Vote for this project in the Egg competition to show your support and keep me risking my laser.*

I recently set up my laser engraving business, and have had to put instructables on the back burner. Which has been a shame, but I'm back now and am going to use the opportunity to try something new and to say thank you for support in the past by giving a 3 month pro membership to any a random commenter.

Step 1: What Eggs to Use.

When starting I had no idea what colour the egg shell will engrave. However I made an educated guess at white this means we want the darkest egg shell we can source, which would be Maran or Welsummer however I had to settle with Barred Rock as I had limited time or suppliers.

What to look for in your eggs;

  • Even shape
  • Dark colour
  • No cracks
  • Long Expiry

Step 2: Making the CAD

There is a few types of design which you can used I have put a simple versions below, most of the designing however is just going to be text so it is not necessary to perform most of the methods. (If you want any more information on how to perform one of the methods just ask in the comments.)

  • Make a design, over-detailed or overcomplicated images do not present well (avoid shading). So make sure you take your time and be willing to give up and find a new idea if you have to.
  • The simplest method of image preparation is just flattening the colours. Using whatever software you have change the image mode to black and white it works well on pictures which were originally black and white.
  • Thresholding is a method which converts the source image to black and white based on the luminosity of each pixel. Bright areas will end up as white and dark areas will end up as black. This method is very effective on evenly-lit images and tends to be one of my preferred methods.
  • Vector Tracing my main method start by opening an image in Adobe Illustrator (or other software) and select Object then Live Trace. Adjust the threshold, blur, path fitting and minimum area settings to produce a vector version of your image.

Step 3: Holding the Egg in Place.

The eggs as you might expect cause a lot of problems for example the egg moving, or the egg cracking, or leaking. To fix this I tried a few ideas but the best idea ended up being bluetack inside of a bowl. As shown in the picture above.

Step 4: Engraving the Egg

To start I made a design with "#Easter" on it to try find the correct setting which were speed 500 , power 70 and scan gap 0.04. From here I then engraved a set of eggs with a few different designs on them, including some logos of local businesses.

Step 5: Displaying the Eggs.

Now the eggs were engraved I decided to display them in a bowl with tissue to protect them as the eggs are still raw. Thanks for reading, please vote for us in the egg contest and also comment below for the chance to get a 3 month pro membership.

Hey Ross, what cad and cam software did you use for the eggs?

1 reply

I used Inkscape (CAD) to turn the images into vectors and then export in to LaserCut5.3 (CAM) as a DXF. (Normally I use Coral Draw, or Auto CAD but I wanted to be quick and accuracy didn't matter as much.

Not random. Just new. If I get an idea and I can write an instructable about it I do.

Sorry, wasn't saying your instructable or cool idea?, was random. Just my strange sense of humor, told me to comment "random" for the Pro membership give away. You stated that you would pick 1 "random" comment. Again very cool idea and great job!

I like your humor, never know you may win. Ps. Sorry it's hard to show context or tone in text.

I forgot: ...and other events:-)

Not sure what other events but great for Easter.

That's actually so cool! Did you think of boiling the egg beforehand to make it less fragile or would that have affected the laser cutting in some way?
Also, did you have any issues with the egg not being flat? I would never have thought of lasering something so round. Great job though, looks awesome

I made sure that the size of what I was engraving fit within a 2mm height from lowest to highest point that way the laser was always in focus. As for boiling them while it would take away some of the risk and might even give a better engraving as the egg would be softer I saw it as an unnessacery step so went without.

Wow! So unbelievably unique. What types of tool do you need for this? I voted for you, now do me a favor and pick me so I can win something before I die and prove to myself I'm not eternally unlucky lol. Really though, you're amazingly talented.
