First prototype

Morning

My idea so far was building a four-legged spider-like figure using inserts to insert the legs.

My initial concept entailed utilizing a joint that could be inserted and then twisted to secure it in place.

Subsequently, I created several sketches of the overall structure.

Second class

I familiarized myself with the process of loading and unloading filament from a Prusa printer.

Initially, I attempted to utilize Fusion 360 to design my prototype, however, I found the software to be cumbersome and unintuitive, so I elected to use Shapr3D instead.

My initial objective was to create the main body of my spider-like structure, so I employed an octagon inscribed within a 60mm radius circle.

In addition, I added eight inserts, each measuring 21.1132mm x 0.5mm, positioned 3.5657mm apart. The height of the prototype was then increased to 1mm.

After completing the prototype, I configured Prusa Slicer with the MKS3 settings and enabled the SPEED option for two layers.

The initial printing time was one hour, so I subsequently decreased the height to 0.5mm and then to 0.3mm, ultimately reducing the printing time to 30 minutes.

I initiated the printing process utilizing the SPEED option with two layers at 0.15mm each and a temperature of 180°C.

During the printing phase, I observed that one of my inserts had an incomplete side, and upon reviewing my sketch, I was unable to identify the cause of the issue. I ultimately concluded that it was an error with the printer.

Despite this issue, the overall result was promising, and further investigation is necessary to optimize the temperature and layer options.
