Fabrication Week 3

This week we are learning Laser Cut. I didn’t have any experience before, so this is the very first time for me to get in touch with laser cut.

At the first time I made a huge mistake: I booked the 75W machine, which according to my friends, is the worst choice for new hands.


I needed to adjust everything manually, and I always forgot to change the button from “focus” to “job”, which took me lots of time.

This is how I learned to adjust it manually:


Finally I made a maze, based on a picture I’ve found online. But I’m not satisfied with this little project.


The other day, I found a new piece of wood, and I cut it to fit the machine.


Then I found a picture I like from internet, and I drew the line of the picture in Photoshop, and then I imported it into Illustrator.


The shop ran out of tapes, so I needed to use small ones to fix my wood piece.


After setting up the speed and power and everything, it started to cut.



For fear that it could not cut deeply, I cut it twice.


But it turned out that I was wrong: it’s still not deep enough. When I took out my “Tree”, several parts broke, because the wood hadn’t been cut thoroughly. So I needed to stick my branches and leaves back together.


Finally this is how my fragile tree looks like:


And you can still see the tiny patches on it.


As for why I chose to cut a tree, it’s from my favorite poem back in high school, “A Blooming Tree” composed by a Chinese poet Xi Murong.

“May Buddha let us meet
in my most beautiful hours,
I have prayed for it
for five hundred years.
Buddha made me a tree
by the path you may take,
In full blossoms I’m waiting in the sun
every flower carrying my previous hope.
As you are near, listen carefully
the quivering leaves are my waiting zeal.
As you pass by the tree
without noticing me,
My friend,
upon the ground behind you
is not the fallen petals
but my withered heart.”

Fabrication Week 2

This week we are making 5 duplicated stuffs. I decided to make five dices.

Firstly I picked appropriate wood (plywood is not a good choice for making small pieces) and measured sizes.


Then I cut the wood into pieces, as I expected how my dices would be like.


Then I polished the wooden pieces, so their surfaces would be smoother.

Once again, I polished them on abrasive paper to fix the tiny defects.

While polishing them on the machine, I accidentally broke my nails – it didn’t hurt so much, but it scared me.


Finally I got the basic shapes of my dices.

Now it’s time to drill holes on them. Firstly I need to make sure where the holes should be.


I tried different machines. Firstly I tried this one, but it was hard for me to control the specific position where to drill, and it was also a trouble since I needed to switch to different surfaces and adjust the machine once I finished.


Finally I decided to drill holes manually. And after drilling all the holes, I polished them again.


So here are my dices!

Fabrication Week 1

This week we are making flash light.

Because I’m still confused with (and afraid of) cutting woods, I chose to make my flash light with paper cups.

I got my materials very easily: two paper cups from ITP kitchen (I ruined two at the first time when I tried, so I took four actually), dark red knitting wool from soft lab, LED and a small wooden stick from shop, and a button cell battery from a mini flash light I had.


Firstly I cut two cups and drilled a hole on each one by scissor. Then I used the knitting wool to get through the bottoms of each one to connect them together. Then I insert the LED through the top hole.


Then I painted a piece of paper to red, and cut it into strips.


And I painted the lantern to red, and connected it to the paper strips and the small wooden stick. Then I sticked one side of the LED with the battery, and covered this part with the left part of the paper cup.


Finally, my flash light works like this:

Happy Halloween!!!
