Abstract
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.

A method for making a three-dimensional object with an additive manufacturing system, the method comprising:
- printing layers of a support structure from a support material, the support material comprising more than 50% wt. of a semi-crystalline polyamide (A) having a melting point, as determined according to ASTM D3418, of at least 250° C. and possessing a water uptake at saturation, by immersion in water at 23° C., of at least 2 wt. %,
- printing layers of the three-dimensional object from a part material in coordination with the printing of the layers of the support structure, wherein at least a portion the printed layers of the support structure support the printed layers of the three-dimensional object, and
- removing at least a portion of the support structure from the three-dimensional object to obtain the three-dimensional object.
