Tiger Coatings is using 3D additive printing to produce spare parts for Austrian Railways ÖBB, achieving EN 45545. One example is retrofit safety rings to ensure that baby carriages do not open doors unintentionally. The rings have to be produced in small series, to specific specifications, conform to railway fire and smoke standards EN 45545. Tiger Coatings TIGITAL are 3D-print compounds for SLS – CBAM 3D-printing (Selective Laser Sintering – composite-based additive manufacturing) and can achieve UL 94-V0 (2 mm), UN ECE 118 Annex 6-7-8 and EN 45545 (HL 1-2-3) with UV resistance, chemical resistance (DBL 5404), notch impact and tensile strength performance, >70% reuse of printer compound, low print temperatures (65-67°C), no pre-drying and non-halogenated PIN flame retardant. The compound is compatible with all open SLS print machines, including Farsoon, Prodways, Weirather, Nexa3D, Sinterit.
