US Patent 9592530 Additive manufacturing with polyamide consumable materials

A consumable material for use in an additive manufacturing system, the consumable filament comprising a polyamide blend of at least one semi-crystalline polyamide, and at least one amorphous polyamide that is substantially miscible with the at least one semi-crystalline polyamide, and a physical geometry configured to be received by the additive manufacturing system for printing a three-dimensional part from the consumable material in a layer-by-layer manner using an additive manufacturing technique. The consumable material is preferably capable of printing three-dimensional parts having good part strengths and ductilities, and low curl.
