5. 3D Scanning and Printing

Individual assignment

3D design

Made a little octopus

Omnidirectional joint

Section analisys of the joint

Section analisys of the ball

First print had a few misstakes the print stuck to the wall and im not sure how to fix that yet

Ok it took a bit long but i made it. So i made a universal joint instead there were a few problems

So the main problem was that the joint was breaking at the middle and the hole points. So what I did is i put a circle in the middle.

But then it just broke when the circle ended so i added a chamfer.

To print, we use the 3D print option, and it goes directly to Pruisa.

it still broke but it was much more durable, so what i concluded was the problem was the angle at which it was placed on the board. So during the 3d printing it was placed on one of the legs and what happened was that the sides were placed at a 90 degree angle so it drooped down.

and even tho it still droops down at some points It doesnt droop down at the points where it matters.

So what did I change? I made the print have more perimeters because it was breaking in the thin points.

Increased the infill. Made the support organic and started from the base plate only because it was hard to remove. Also auto generated them. Reprinted like 5-6 times fixing small mistakes every time so im really happy that in the end it worked

3D Scanning

For the scanning, I used an app “xone” on my phone and took 20 pictures. Here is the result.
