5. 3D Scanning and Printing¶
Overview¶
This week I learned more about 3D desgin and learned about 3D printing and scanning. For 3D design I learned about how its diffrent compared to a subtractive design. For printing I learned about the settings in my group work and how to use a 3D printer for individual work. With scanning I scan objects around my house with and printed it.

Diffrence between a CNC Machine and a 3D printer¶
In my understanding of the diffrence between the two machines was that the 3D printer is additve manufacturing while the CNC machine is subtractive manufacturing. I recently learned though that the CNC machine is able to make lots of designs the can be made with a 3D printer. For example, while it would take a long time, a cube can be shaped into a sphere through an stl design. The first assignment of the week was to design an object that couldnt be made using subtractive manufactoring. To understand what the CNC machine couldnt do that the 3D printer could I asked ChatGPT to tell me the diffrences in what the CNC Machine could do when it came to making 3D models that the 3D printer could. One line that stood out to me in what chat said was that the CNC Machine couldnt make complex designs.
Designing my 3D printer only object¶
With the new found knowledge on what the diffrences were in designs for a CNC and a 3D printer I began making my design. To start with I made a cube. This cube was then given small holes in the middle of them on all sides. After that I shelled the cube so that I would have somewhere to make my complex part of the design. To add the ring I made a plane based off three points and chose two that were diagonal to each other and the last one as the other end of the side. With this new plane I made two cicrles in the middle with one slightly bigger then the other. This allowed me to make a ring with the extrude tool around the cross
