Abstract
A method for producing an object comprises the step of producing the object by means of an additive manufacturing process from a construction material. The construction material comprises a first polyurethane polymer which has: a weight percentage ratio of O to N of ≥2 to ≤2.5, determined by elementary analysis; a weight percentage ratio of N to C of ≥0.1 to ≤0.25, determined by elementary analysis; a full-width at half maximum of the melting peak of ≤20 K, determined by dynamic differential scanning calorimetry DSC (2heating at heating rate 20 k/min); and a difference between the melting temperature and the recrystallisation temperature of ≥5 K and ≤100 K, determined by dynamic differential scanning calorimetry DSC (2heating) at a heating and cooling rate of 20 K/min.
