Week 5: 3D Scanning & Printing
3D Printing
For the 3D printing assignment, we were tasked to print something that would be impossible to make in any other fabrication method. Since I had already used Fusion360 and Rhino in previous assignments, I decided to use a different 3D modeling software to practice and experiment with. For intricate geometries, I chose to use Maya 3D in order to design a geometry that would not only be impossible to machine, but also test the limits of our 3D printer. I documented my process in a timelapse below, where you will see that I was utilizing a few basic commands to create a complex geometry. Starting with a cube, I extrude the face, move it into a new position, bridge two faces together, and implement multiple mirroring commands along the X, Y, and Z axis to explore what forms emerge. In the timelapse you can see how I use these commands to create more layers and complexity, as well as to eliminate complexity until I found an aesthetic form that would not be able to be machined due to its overhands, floating elements, and undercuts.
Maya 3D Modeling Process:
I used a BambuLabs X1C to print the object. I had to edit the support angle in order to successfully print the floating elements. When I went to use the special bambulabs support filament, it made the print 3 times longer so I reverted back to print supports in the same PLA plastic. I was able to remove these fairly easily with little damage to the part.
3D Scanning
The 3D scanning process I tried was with the lidar capabilities of the iPhone 15 using a free app called Scaniverse.
For a free app, the software was able to capture a fairly accurate 3D model. I tested the scanning capablity by capturing a 3D print of a John Edmark sculpture. The scan captured the layer texture of the 3D print but had blurrier features where the lighting was inconsistent.
Scaniverse Results:
I tried different lighting methods, rotating the object versus rotating slowly around the object, and running multiple passes in different angles. The best result was when I walked slowly around the object and alternated the angle above the object after each rotation.
