Introduction: Laser Etched Drinking Glasses
A while ago I laser etched my face onto a set of drinking glasses in hopes of weirding out my new roommates. They didn't seem to notice. Or, at least, if they did notice, they never said anything. Any which way, it never sparked the conversation I was hoping for (i.e. "Why do you have your face on all your glasses?"). Regardless... these glasses make a fine addition to any home.
The nice thing about etching glass with a 75 Watt IR laser cutter is the precision and detail. I am able to get highly accurate images onto a round surface without much fuss. I highly recommend pulling your awesome Epilog laser cutter out of the closet and doing the same.
Step 1: Go Get Stuff
You will need:
An awesome Epilog Laser Cutter
A rotary attachment
A container with water
Blue painters tape
A digital image of your face
Step 2: Attach the Rotary Attachment
Turn on the laser cutter. Drop the bed to the bottom and remove the honey comb panel.
Turn off the laser cutter. Align the pegs of the rotary attachment into the pegs in the bottom of the laser cutter. Plug in the ribbon cable into the socket on the side of the laser cutter.
Turn the laser cutter back on.
Step 3: Testing
Cover your glass with blue painter's tape. Place it onto the rotary attachment with the larger side of the glass closer to the cut head and use the dial to adjust the glasses height until it lays level.
Raster cut the tape with the following settings:
You can use the cut file attached below to get started. Keep in mind this file is of my face. You will need to make one of your face.
Figure out your measurements for your own cup and plan accordingly when making your image file.
Step 4: Make the File
Open a picture of your face in Photoshop.
Use the lasso tool to outline your face.
Once you close the outline, copy your face and paste it into a new document.
Now, apply the stamp filter to it such that it is a black outline with a white fill. You should now be all set.
Step 5: Soap the Glass
Apply a small amount of dish soap to the surface of the glass, being particularly careful not to get the soap on either end of the cup. If you get soap on the ends, the wheels on the rotary attachment won't grip and your glass will just spin in place, causing the etching to fail.
Step 6: Coat the Glass
Cut out a small piece of paper towel. Soak it in water and the wring it out and then carefully reshape it so that it is flat.
Place this paper towel around your glass. Smooth it out to get out any bubbles, but be careful to keep this off the edges of the glass as well, as it will interfere with its rotation.
Also, be careful not to let the paper towel overlap itself as this may alter the results of the etching.
Step 7: Place the Glass
Place the glass in the rotary cutter with the larger edge closest the cut head. The glass will spin clockwise, so position it as such. In other words, put it in there so that the right edge of the paper towel is about at the 1 o-clock position if its spinning clockwise.
Step 8: Etch the Glass!
Etch the glass with the following settings:
Step 9: Clean It Up
Wash off the glass in the faucet with running water.
You may want to consider scrubbing the etching with a little steel wool to get rid of any possible sharp edges.
We have a be nice policy.
