Abstract
An example of a three-dimensional (3D) build material composition includes from about 70 wt % to about 95 wt % of polyamide particles, based upon a total weight of the build material composition; and from about 5 wt % to about 30 wt % of biodegradable polyester filler particles, based upon the total weight of the build material composition. The biodegradable polyester filler particles are present in the build material composition without any additional filler particles.
