I am just beginning to create what will be my first Shapeways-printed model. I'm using (and learning on the fly!) Blender for this purpose. The most prominent part of the model will be made from a 2D curve that is spun/lathed about an axis, much like the various tutorials that you'll find online for creating a goblet or chess piece. I'm wondering how dense the mesh will need to be in order to avoid a faceted look in the 3D print. The shape that I'm making is roughly cone-shaped, although there is a gentle curve from the base of the cone to its tip. The shape will be about 7 cm in diameter and 10 cm in length. What would you suggest? Thanks in advance!
