After several successfull prints I had my first failure today.
I printed the following thing:
And during printing iit came loose of the heated bed and messed up the result.
There are a few things that might be interesting factors:
1: I had to rotate the model 45 degrees to fit it on the bed. This caused the infil to line up with the model. Normally its at a 45 degree angle to the model.
2: The room cooled down a lot during printing. And the heater in de back of the room switched on. This might have caused hot air to reach the model during printing.
3: The reason it came loose is because the model bottom has curled up. This happened in the later stage of printing. (see included photos)
4: It failed before the last 20 passes of the outer ring. And then made a wonky stack of hay out of the chimney. Thee top of the boat (with lego studs) was printed perfectly. Lego fits.
So, my question: Why did the model deform after so much printing time. Was it the heat from the heater. Was it the angle of the inner support structure. Did I not say enough nice words to my snapmaker… Any pointers would be great. I’m eager to learn.
