I know Ben (our instructor) told us not to fall for laser cutter, but it’s too late. This is like the coolest thing ever. My goal for this week was to finish my mini tea coasters project, so this is exactly what I did.

I had 6 pieces that I wanted to etch with my cup of tea logo.

First I tested on a scrap wood:

At the first laser didn’t work and I wasn’t sure why. I thought it may be because of the file, so I copied everything onto computer’s template, but still, nothing. By nothing I mean that it kept giving me “done” notification even though job hasn’t even started yet.

It turned out that the reason for it was that I had 0.1pt stroke set up (weird) and only after I set it to 1pt, it started going. You can see the result above (the lowest line). The settings there are 30/100 (speed/power).

I didn’t like how the wood burnt (you see the darker color above the font), so I started playing with different settings: changed speed to 50 and later to 70, but kept power the same (final settings for work is 70/100). I also made the black font (before it was like a frame with white inside). Here’s how it looks like:

I laser cut both sides.

I was also lucky to have my tung oil shipped by Amazon, so I could finish the wood.

I wiped the surface and let it stay for 60min. I may need to do the second application 12 hours later, but well see tomorrow. Here’s how it looks like now:

Second idea

Since it got done really fast (thank you, laser cutter), I thought what to do next since I wanted to play with laser cutter a bit more.

I have a smarter classmate campaign running and I’m in a hurry to send around 60 postcards to all over the world. And why not use laser cutter for it, too? It would have taken a long time to cut the entire text, so I only engraved “smarter classmate” sign on each of the postcards.

I first tested on an empty postcard:

2015-11-09 12.04.13

And then did the rest:

2015-11-09 12.32.15

2015-11-09 15.54.57

Now all I have to do is put stamps and send them out.

Update: I’ve also tried etching the entire postcard text, here we go:

One thought on “[fabrication] week3: laser cutting (part2)”

  1. Nice work. I’m glad you tried using the tung oil and that you tested your settings on scrap wood.

    If you have any postcards left, maybe you could try cutting out the letters. Might look interesting.

    Don’t fall in love with the laser
