Abstract
A polymer material in manufacture of 3D articles by means of additive manufacturing, the polymer material including: a) at least one propylene polymer P having a flexural modulus determined according to ISO 178:2019 standard of at least 150 MPa, b) at least one propylene-based elastomer PBE having a flexural modulus determined according to ISO 178:2019 standard of not more than 100 MPa, and c) at least one solid inorganic compound SC.
Claims18
A method for producing a 3D article comprising the following steps:
- i) providing a digital model of the 3D article;
- and
- ii) based on the digital model, printing a polymer material using a 3D printer to form the 3D article, wherein the polymer material comprises:
- a) at least one propylene polymer P having a flexural modulus determined according to ISO 178:2019 standard of at least 150 MPa,
- b) at least one propylene-based elastomer PBE having a flexural modulus determined according to ISO 178:2019 standard of not more than 100 MPa, and
- c) at least one solid inorganic compound SC.
