Week 2

Things I did this week:

  1. git setup
  2. characterize lasercutter
  3. vinylcutter
  4. parametric construction kit

git setup

Git setup was fairly easy for me since I have a strong software background. I just used the old rsa key I generated before and added that to GitLab. I used a website template and built based on the template.

characterize lasercutter

Since the laser cutter at the REEF makerspace was unavailable during weekend, the below measurements corresponds to the laser cutter in GSD.

characterization measurements
focus 2.5 inch
power 120 watts; 70%
speed 7
rate PPI 250
kerf ~0.15 mm, hard to give an exact number b/c material thickness varies, and kerf varies. Also the material was soft, and therefore hard to measure procisely.
joint clearance ~0.15mm
types CO2

vinylcutter

  1. I first searched for an image online, and removed the unwanted white background. This design turned out to be undesired because I want a circle bounding box instead of a rectangle.
  2. I cut out the design on vinyl premium material.
  3. This is what I did wrong. I supposed to weed first before applying the transfer tape.
  4. This is the back side of the failed case after I peeled it off.
  5. I corrected the design and printed it again.
  6. This is what it looks like after weeding. The dots for the eyes were really hard to stay where they should be.
  7. I then applied transfer tape to the design.
  8. Half way through peeling.
  9. Finished peeling the transfer tape. I was able to stick the design onto a piece of cardboard paper.

I continued to cut pop up cards.

  1. I found this amazing pop up card template.
  2. I cut out the design on light cardstock paper. The vinyl machine cutted somewhere it doesn't suppose to cut, and some parts were too thin and broke while I was removing things.
  3. I removed all the unnecessary parts and was able to fold it out. It was very hard to remove the small paperstock pieces and it was sticking to the mat, but turned out being a nice pop up card.
  4. Trying a different design that seems to be easier to accomplish.
  5. Some details in the middle were still missing. I also cut my name on premium vinyl as well.

parametric construction kit

First time designing in CAD. I used Fusion 360!

  1. I designed a hexagon shape cuz I think they can be easy to work with. I simply added a slot per side so that I can play around with it.
  2. I used laser cut to first cut out four pieces to try with.
  3. It wasn't easy to slide the pieces in their slots, that's when I realized that I forgot to fellit the design. When the pieces were finally place together, they were combined nicely, and very tightly.
  4. This is some of the parameters that I used.
  5. I cut out a lot of pieces to play with.
  6. This is after I took away the unnecessary cardboards. Then when I tried to put the pieces together, I realized it was too loose, and the slots were too big. It turned out when I was editing the design to fellit the slots, I accidentally hit command-z and reversed the slot size.
  7. Although it was the failure case, I still tried to build something from it. The "bowl" turned out pretty nice, and combined in this way the whole structrue was actually fairly tight.
  8. This is the final 3D design.
  9. I built a large snowflake.
  10. Here is a different view of the final product.
