FROM THEORY TO PRACTICE — CNC router experiment

For printing a bigger model, I tried CNC router. This machine printed objects are rougher that 3d-printed objects. The materials could be wood or foam, but the tool is not long, so the file in CNC could not deep, so I must cut my car in the middle into two sides. Then put your foam into this machine, stick on the board and clamp it tightly avoiding moving. Then, tell the machine where the foam is and where need to start first, tell machine everything about how deep it need to go and the size of the tool itself. It looks like teach primary school students.Then it will start and you need to close the door before it starts, then you can see the flying swarf.

After half an hour seeing the tool cycling looping from left to right, I got my half model. Then I did another half. I found I didn’t cut them in the middle even it looked like in the middle, the right one is a little bit thicker than the left one. So I mirrored the right one and printed one more. After I got whole models, I started sanding it with sand paper, and glued them with PVA in order to make them harder.

Finally, I made a tissue box for Uber drivers as a lucky charm.
