Knowing how to orient your model for 3D printing correctly is one of the biggest challenges in getting effective parts. Stratasys systems use soluble support material, which means almost any orientation can work to 3d print a model. However, orienting a print to not fail is only the tip of the iceberg. Depending on the geometry of a part, you may want a certain face or feature to look perfect, the part to be strongest in one direction, or to minimize the amount of support material used to reduce print time and cost.
I have created three example models that emulate common 3D printing situations, and will walk through how I would orient these models, prioritizing surface finish, strength, and minimal support material use. These parts provide hypothetical situations where you might use the part to give insight for different applications.
