The methods can include printing the support structure along with the article, where the article can be removed from the support structure after the production process. In some embodiments, a method includes: determining a concave hull from an article to be 3D-printed, wherein the article to be 3D-printed comprises a plurality of fibers; determining one or more support pillars for connecting the article to be 3D-printed and a support surface; and printing the one or more support pillars and the article to be 3D-printed together using a 3D printing method. Also provided herein are methods for determining the geometry of the support structure and the supported 3D-printed article produced by the methods described herein.
