Thermosetting material for use in additive manufacturing

A method of producing a cured 3D thermoset object comprising at least the following steps:

• a. Subjecting a thermoseiling material to an additive manufacturing process;
• b. obtaining a partially cured 3D thermoset object and;
• c. subjecting the partially cured 3D thermoset object to a post curing process to further cure the 3D thermoset object,
• wherein the thermosetting material comprises at least one thermosetting resin and at least two curing compounds different from said thermosetting resin able to cure this/these thermosetting resin(s), wherein at least one curing compound is provided for curing during the additive manufacturing process and another at least one curing compound is provided for curing during the post-curing process,
• wherein the thermosetting material uses a purely thermal curing system, and wherein at the least one curing compound has an activation temperature of between 70° C. and 130° C. and another of the at least one curing compound has an activation temperature of greater than 130° C. with the activation temperature being determined by means of DSC analysis with a heating/cooling rate of 20° C./min.
