	Desktop fabricator may kick-start home revolution - tech - 09 January 2007 - New Scientist Tech
		Rapid prototyping machines are already used by designers, engineers and scientists to create one-off mechanical parts and models.
		The standard version of their Freeform fabricator — or "fabber" — is about the size of a microwave oven and can be assembled for around $2400 (£1200).
		Adrian Bowyer, who is also working on rapid prototyping machines at Bath University, in the UK, agrees that the technology could have mass appeal once the equipment is cheap enough.

	Description
		The overarching vision for the Center for Rapid Automated Fabrication Technologies (CRAFT) is to develop the science and engineering needed for rapid automated fabrication of objects of various size up to mega-scale structures such as, boats, industrial objects, public art and whole building structures.
		Contour Crafting (CC) is a hybrid fabrication method that combines extrusion for forming object surfaces and filling to build the object core in layered fashion. As shown in the upper left corner of Figure 1, the extrusion nozzle has an adjacent trowel.
		Contour Crafting falls within the class of Rapid Prototyping, or Solid Freeform Fabrication, technologies, but the use of thick layers plus troweling to provide a high quality surface finish and rapid fabrication time affords a scaleup pathway to the rapid fabrication of large building-sized structures that no other technique provides.

	Rapid Manufacturing (Site not responding. Last check: )
		Rapid Manufacturing (RM) have been developed to shorten the design and production cycle, and promise to revolutionize many traditional manufacturing procedures.
		Although the layer fabrication process itself is typically not as fast as traditional mass production techniques, it eliminates tooling, setup, and assembly processes, can produce parts of superior quality and complexity, and can be ideal for making custom parts based on a customer's special requirements.
		However, in layer manufacturing the fabrication process builds the part systematically by adding material instead of cutting it away, and a much wider range of shapes can be achieved, including cavities or intricate geometries that would be difficult or impossible to machine.

	Rapid prototyping - Wikipedia, the free encyclopedia
		Rapid prototyping, is the automatic construction of physical objects using solid freeform fabrication.
		The first techniques for rapid prototyping became available in the 1980s and were used to produce models and prototype parts.
		In brief, rapid prototyping takes virtual designs (from computer aided design (CAD) or from animation modeling software), transforms them into cross sections, still virtual, and then create each cross section in physical space, one after the next until the model is finished.

		The melt pool in the substrate combines with the fed material, which also completely or partially melts in the beam, to create an interface bonding the substrate material to the clad surface, and a surface of clad material in which dilution by the substrate is kept a minimum.
		Laser cladding has been extended to applications such as component repair and rapid fabrication, which may be covered by the less specific term ‘Laser Material Deposition’.
		Rapid replacement of vital tooling is inevitably costly: laser tool recovery could substitute replacement by repair, and cut down time drastically, as the process is fast when compared to the replacement of tools not bought off-the-shelf.
