I am making a model in Blender for 3d printing and have non-planar faces on my model. Can they mess up my print?

(non-planar faces are faces that are not straight ("twisted"))

Yes, non-planar faces can cause issues during printing, such as gaps or inaccuracies in the final print. It's best to ensure all faces are planar for better print results.

You want a "watertight" model. If your twisted faces are not causing holes, you should be good

#

I've often seen blender models with inverted normals - those cause problems too.

If the twist is vertical you'll end up with stairstepping
