Brief : Create a camera support dedicated to photogrammetry using as the structural base A Godox AR400 flash unit.
DESIGN PROCESS
The modeling process was carried out on 3 CAD softwares:
Reality Capture, Fusion 360 & Rhinocéros 7
I've used Rhinoceros 7 to quickly model the base surface 3d model of the ergonomic handle. I used a 3D scan of a clay prototype I'd previously sculpted and scanned. Then I've exported a .STEP file to Fusion 360 in order to add details and assembly features.
I was able to take advantage of the 360 parametric fusion functionality to easily adjust the tolerances of each element. The software also enabled me to create an assembly to preview the final product.
The prototyping process has involved a large number of iterations for each of the final product parts. Each component version was used to validate or invalidate strength and dimensional tolerance criteria.
Creating an aesthetically, pleasing and durable product using FDM 3D printing was a real challenge. However, the ease of quickly testing new ideas and managing key printing parameters (layer height, infill ratio, printing temperature...) with precession reinforced my understanding of many materials.
Choosing carbon fiber rods as the frame material saved me a lot of weight. Some of the weight saved by the carbon tubes was able to be transferred to the 3D-printed parts, improving their strength. My decision not to rely exclusively on 3D printing for this product was driven by a desire not to compromise on the look, strength and reliability of the final assembly.
