Document Summary
Most accessible and widely used form of am. Predominant technology at the consumer level, with variations found at the industrial level build parts layer-by-layer from the bottom up by heating and extruding thermoplastic filament, most commonly pla & abs. Production-level systems work with a range of standard, engineering and high-performance thermoplastics with specialized properties like toughness, electrostatic dissipation, translucence, biocompatibility, uv resistance, and high heat deflection. Fdm is ideal for a range of applications from classroom projects and basic proof-of-concept models to lightweight ductwork installed on commercial aircraft. Feed filament from roll to hot end. Layers at a time in the shape of the object cooled on build plate. Time-to-market: adapted to ever shorter product life cycles through flexible additive production method. Practically no restriction on the geometry to be produced. Reduced capital tied up in stocks, as parts can be printed quickly and easily. Shorter assembly times due to integrated function lead to direct cost savings.
