ABS (Acrylonitrile Butadiene Styrene) (FDM, UltiMaker ABS)

UltiMaker ABS is a filament grade of acrylonitrile butadiene styrene made by UltiMaker for fused deposition modeling. Printed parts are built from fused extruded roads, so strength and toughness are lower across layers than within them. The layer lines leave a ribbed surface that is often sanded or smoothed with acetone vapor. ABS shrinks on cooling and tends to warp, so it is printed on a heated bed, preferably in an enclosed chamber, with supports under overhangs. Parts serve as functional prototypes, housings, jigs and fixtures that need more heat resistance and impact toughness than PLA. Every value on this page is read from UltiMaker's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
