5. 3D Scanning and Printing¶
Overview¶
The goal of this week was to learn how to test 3D printers, create new types of 3D models, and test 3D scanning. In my group I worked on testing multiple different lengths of bridges.
Group Work¶
Get to the group work page here.
I learned how to create, modify and test all kinds of bridges whilst 3D printing.
Files¶
In these Files there is the Fusion model and the PolyCam scan.
New 3D model¶
Overview¶
For creating this new kind of 3D model I was told to create a model that could not be replicated by a subtractive type printer. Because of this requirement I decided to create a ball with a rectangle in it, this design is impossible to replicate with subtractive printer. However I decided that I wanted the ball I created to look special so I took some strange steps to create it in Fusion 360.
Process¶
I got the idea from Adrian Torres who created his own Voronoi pattern in Rhinoceros, another 3D design software. I followed this tutorial video on youtube, it was extremely helpful go like and subscribe. It walked me through how to create my own Voronoi pattern in Fusion 360. Below I will detail the steps.
A. Step one I created a sphere of any diameter, although a larger size is recommended.
B. On the Mesh menu I used the tool tesselate I to weave a very complex and unprintable version of the pattern into the sphere. I will correct this later. Adjust the deviation for different patterns.
C. Next I used the reduce tool on the mesh menu to simplify the amount of faces being created. Less than 800 faces are recommended. Then I needed to convert this mesh to a parametric design. I clicked the tool convert mesh then selected parametric.

D. After this I needed change my selection settings so I could only select the edges of the design.
Selecting only the edges
E. Then I could click create form which would create the outline of a hollow sphere with the pattern. This completes the video and the sphere.
Creating the form.
F. Finally I would sketch and extrude a rectangular prism inside the cube, finally creating my additive only 3D print.

G. Printing this was not fun. It required a mess of supports that took a very long time to remove but it worked so who cares.
G. The final product after post processing it.
3D Scanning¶
Overview¶
In order to accurately 3D scan an object in real life I needed to download the app: PolyCam which is specifically designed to use my phone camera to take many pictures and accurately create a 3D model.
Process¶
There was really no detailed process to this but to follow the steps the app gave me.
A. Download the app: PolyCam
B. Selected my water bottle as my real life object
C. Took around 150 pictures of almost every conceivable angle of the bottle for the app.
D. I waited while it generated my model.
E. I exported my model as a GBL file and then converted it to an STL file that I could then edit.
These are the pictures of the model that was generated.
