[Junior question of the day] Why is it so tilted

[Alexandre Beyls]

Looking at the last Moai's kickstarter update, we have this great picture below (by Helmi).

We also have some great pictures on Peopoly twitter that share the same characteristic.

The question is : why is the model so tilted.

Is it some pre-requisite for a good print ? 

Or is it an old habit from when it was really needed due to technological limitations ?

Is it something else ?

If I remember correctly, none of Peopoly prints uses this technique.

So, what is it ?

Sometimes you don't want to print the bottom flush with the build plate because it might not come off very well or it creates too much suction for when the resin vat moves up and down. Plus the bottom of the model might get damaged from the blade you might use to get the model off so supports make it easier to remove without damage.

The other reason to consider model orientation is to make sure it builds off itself.  Looking at this model, I see a large overhang on the snout.  By printing it at this angle, the model builds off itself and fewer support columns are needed.  Specifically, zero support is needed for the head, snout, and ears.

Support is often times unavoidable, but model orientation can put it in lower detail areas which shortens the print finishing time and can yield an overall higher detail part.

Happy printing!
