I took the opportunity to burn in the logo for the school I work at, the Boulder Outdoor Survival School. The biggest challenge was figuring out how to align the lid in the laser cutter. Once I figured that out, the rest was easy.
Note that I don't go into a lot of depth about how to use the laser cutter, but I assume if you have access to one, you know how to use it or have access to someone who can help (e.g. at Techshop).
- a Klean Kanteen reflect bottle (or just the lid)
- some scrap bamboo to test the laser settings
- some cardboard or other material to use as a template
- masking tape to prevent scorch marks
- fine steel wool to buff any scorch marks
- access to a laser cutter
Step 1: Create the Artwork
Create two concentric hairline circles (vector), one of 5 cm and one of 4 cm. The 4 cm inner circle is used to cut a hole in the template to hold the lid in place. The outer circle is used to check the alignment of the lid in the machine.
Once you have the circles, position your logo in the circles.
Step 2: Test the Laser Raster Settings
For this step, you'll need to focus the laser and you may need to reset the home position for each subsequent test. Also, be sure to use the raster only job type (not combined) so that you don't wind up printing the circle vectors.
Step 3: Create the Template
1. Refocus and home the laser for your template material
2. Temporarily delete the 5cm outer ring (so that it doesn't print)
3. Set your template material in the machine
4. Select the Vector only Job Type
5. Run the job to cut a hole in your template
6. Replace the 5cm outer ring in your logo artwork
Step 4: Set the Lid in the Template and Run a Test Job
Remember to first refocus the laser to accomodate the lid.
