Techniques and compositions are disclosed for feedstocks with powder/binder systems for three-dimensional printing, such as fused filament fabrication. For example, a plurality of feedstocks may be combined to form a three-dimensional object having a spatial gradient of a first primary binder and a second primary binder. The spatial gradient of the first primary binder and the second primary binder along the three-dimensional object may form the three-dimensional object with an advantageous combination of adequate structural support and a rapid overall rate of debinding the first primary binder and the second primary binder from the three-dimensional object as the three-dimensional object is processed into a final part. Accordingly, the spatial gradient of the first primary binder and the second primary binder may be useful for rapid three-dimensional manufacturing of high quality parts. |
