Today Part 9 was finished, the first wheel for the Valify Robot lawnmower. The print took around 44h and conusmed approximately 550grams of PrimaSelect PETG filament. I was running this part with 3 shells and 15% infill because the wheel has to handle bumps and other forces. The part that came out seems almost unbreakable (it´s super solid). I needed to print this part with minimal support, because the back is flat. Support was needed to for the gills and the for the center of the wheel where the wheel hub will be mounted.
The print came out great. The layers looks good. The top layers looks also alright. its always hard to get nice layers when printing top layers with a radius. But For this print the looks is not the primary function, instead I need a well balanced wheel and for that is better to print like this. Looks can always be retouched.
So here is the wheel
Here is the wheel test “mounted” on the lawnmower body. One can really see that the robot grows for each part printed. It´s fantastic to see your design coming to life and adding and An additional dimension for which has been created in your head (its a fantastic feeling).
