Assignments

• Design and 3D print an object (small, few cm) that could not be made subtractively (Individual Project)
• 3D scan an object (and optionally print it) (Individual Project)

Summary of the week

Compare with the subtractive manufacturing technique , with the additive manufacturing technique, we can design some unique structures more quickly. I was so excited to print a 3D modeling by myself and also wanna make something which can be used on my final project.So I chose to use tinkerCAD to make one.

3D designing in tinkerCAD

I use the basic structure of an open source robot Otto DIY ,I added a small circle container on the top and poke a hole in the middle to put my LED strips.

3D Printing

I used to ajust the stl file and print it.

Then I printed it out.I changed the PLA filament into the right color. After heating, the new one will replace the old one.

Printing now.

After 13 hours, I got these parts.

3D Scanning

Qclone

I tried several apps and chose the Qclone.I downloaded the scanning mat and printed it out, than I put the pbject onto the mat and scan it. I have to hold the phone steady and spin the mat nicely and slowly.

Here's the scanning results.

With Qclone,I can scan the object from different angles,and merge the result together, but sometimes, it need some paint after scanning. My coworker Yuanhan made a rotation pedestal, I'll use this for my next trial to see if I can get a better model.

Orbbec Camera

I found a nice prodcut Orbbec Persee: World's First 3D Camera-Computer on Indiegogo. So I tried to use it to scan my body.
