A PROCESS FOR FABRICATING A FLAME RETARDED THERMOPLASTIC PRODUCT THROUGH ADDITIVE MANUFACTURING AND A USE OF A THERMOPLASTIC COMPOSITION IN ADDITIVE MANUFACTURING

Method for fabricating flame retarded thermoplastic products through additive manufacturing, comprising the steps; a) Computing a first, bulk, rendition of a digital three dimensional model and an optional second rendition being an outer surface, b) Printing the first rendition with a composition comprising, 20 - 60 % by weight of polycaprolactone (PCL) having a molecular weight of at least 50.000, 20 - 50 % by weight of polylactide (PLA) having a average molecular weight of at least 100.000, 20 - 40 % by weight of aluminium trihydrate having an average particle size in the range 0.2 ?m and 20 ?m, c) The optional second rendition may be printed onto the first rendition with the same thermoplastic composition as defined in b) but being printed with a high resolution. The invention also refers to use of a thermoplastic composition for additive manufacturing of fire retarded products.
