The invention concerns a vise structure for maintaining parts to be machined, in particular but not exclusively for a micro-milling operation in a fast prototyping process. The invention is characterised in that it consists of a fixing plate (1) provided with reserves suitably distributed wherein is arranged a thermofusible material capable of being reversibly brought from liquid state to solid state whereof the free surface is urged continuously from the surface of said plate, the latter comprising means for heating/cooling (3, 4) said thermofusible material enabling to release/retain the part arranged on said plate.
