The invention pertains to a method for manufacturing a three-dimensional object with an additive manufacturing system, such as an extrusion-based additive manufacturing system, a selective laser sintering system, and/or an electrophotography-based additive manufacturing system, comprising providing a support material comprising more than 50% wt. of a semi-crystalline polyamide [polyamide (A)] having a melting point, as determined according to ASTM D3418, of at least 250° C. and possessing a water absorption at saturation, by immersion in water at 23° C., of at least 2% wt.
