The present invention relates to a method of manufacturing a component 1 by additive manufacturing. The method comprises providing a work surface 2 on which the component 1 is to be manufactured, and providing at least one deposition material 3 from which the component 1 is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area 4 where it is added to the component 1 being manufactured. The method further comprises focusing at least one light beam 5 of incoherent light emitted from at least one heating source 6 in the deposition area 4 so that the deposition material 3 is deposited for building up the component 1. At least one light focusing mirror 7 and/or lens 11 is used to focus the incoherent light in the deposition area 4. The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.

A shape memory alloy structure comprises at least one tubular member formed of shape memory material, each tubular member including a plurality of panels having side edges, wherein each tubular member is moveable between a radially contracted position and a radially extended position, and wherein the coupled side edges of adjacent panels of each tubular member form hinges for moving the structure between the contracted position and the extended position. Multiple layer tubular structures, methods for forming and fixtures for collapsing same are also disclosed.
