Week 16 - Wildcard Week

This week we have the following task to complete:

Design and produce something with a digital process (incorporating computer-aided design and manufacturing) not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce it

4th axis milling

The first project this week is to mill a bust of myself from the 3D scan from week 05. Both parts that I used for the SLA print to put a USB stick inside would be perfect. I put both parts back together in blender with the help from Ferdi because my think of just join both parts together and use the fill command, didn't wrk at all. In the end I just use the remesh function. Before all of this the inner geometry got removed.

The next step was to scale the model to the correct size and import them into Fusion 360 because the cam enviromet from Fusion has good tools to generate G-Code for multi axis maching. In the past I already milled some parts with 4th axis from the Carvera and already use the Fusion cam enviroment for that, with estonishing results.

This time zeroing was a little complicated, because the mill theoreticaly knows the position from the 4th axis and can verify the height by using the wireless probe but our probe is broken in the moment so I could verify the z position and i know that the z position will be a little bit of, because we milled the mdf waste board flat, which removes a few 10th of a mm. To encouter this problem I changed the waste boards and put a completly new on it and didn't max out the size of the bust in realtion to the stock material.

Before I could start milling I prepared my stock, where I saw of a piece of scrap PVC that we got lying around, which hopefully will be a good comparison to the SLA printed bust.

electroplating

The idea was to electroplate a fff printed funnel for a friend who use it to put some dietary supplements in his flasks to consume them while trailrunning. The problem was that over time even if the pla is food grated the process itself isnt and while using it often some delaminations happend while cleaning it by hand. To make it more robust I printed the funnel again and paint it with graphite spray paint. The first version didn't have any hole to hang the funnel in to the electroly so i deceided to print a second version with a small hanger where it can more easily put in the electrolitc solution.

What I learn this week

What I want to improve next week

To create this page, I used ChatGPT to check my syntax and grammar.
