This flame retardant filament is self extinguishing and suitable for 3D prints which have to fulfil the Standard for Safety of Flammability of Plastic Materials UL 94. UL94 is the flammability safety standard for plastic materials. This regulation presents a classification as a function of the time it takes the flame to extinguish once the source of ignition has been withdrawn. Acrylonitrile butadiene styrene or ABS is a highly impact resistant plastic and one of the materials most used in the industry. It is a tenacious, hard and rigid material, with an acceptable chemical resistance and good dimensional stability. Accepts mechanized and is receptive to baths of metals being able to chromes by electrolysis. It is soluble in acetone, which is used to improve the surface finish of the layers. It can also be used to glue different parts printed in ABS to each other. It is indicated when high strength parts are needed. It requires a warm bed. We recommend the use of lacquers for 3D printing.
