Cartesian-XZ: In this configuration, the extruder head moves in X and Z axis while the platform can move to and forth left and right along the Y axis. This is game-changing for material extrusion. Author to whom correspondence should be addressed. When the molten filament or wire exits from the extrusion nozzle either exposed to air or an inert gas chamber, it solidifies immediately on a base or onto a preceding layer. In an industrial setting, material extrusion is used for rapid prototyping. You seem to have javascript disabled. The systems themselves can cost less than $1,000 for an entry-level system for home use to $5,000-$10,000 for a desktop system for prototyping and tooling to $150,000 and higher for industrial-grade systems. For more acute overhang angles and brodges you can print with support material beneath the part, resulting in post treatments which give rise to minimal surface traces. Fused Filament Fabrication is a term coined by RepRap project which is an open source project for development of low-cost and affordable desktop 3D printers. All of these processes are additive in nature and differ only in the way layers are laid out. Material extrusion can accommodate the use of a range of materials, with the most popular being thermoplastics like acrylonitrile butadiene styrene (ABS), aliphatic polyamides (PA, aka Nylon), high-impact polystyrene (HIPS), polylactic acid (PLA), and thermoplastic polyurethane (TPU). Injection molding techniques are fully dense and do not suffer from this anisotropy because the entire plastic part is heated and pressurized in the mold during fabrication. In this review, the available literature is systematically summarised and concluded in terms of feedstock, printing, debinding and sintering. Material extrusion was the second process to be successfully commercialized. Pellets can also be bought in bulk for about 1/5 the cost of filament, and it is easy to add chopped carbon fiber, for instance, to pellet feeders to improve strength.
