| 摘要 |
The invention concerns a method for making mechanical parts and objects, in particular prototypes, from a specific computer-assisted design comprising the following successive steps: making the parts in elementary layers or strata; reconstructing the assembly of layers; assembling the layers, said layers being derived from previous decomposition according to specific planes and one or several step(s). The invention is characterised in that the unit layers determined by the decomposition of the part using a software and machined accordingly comprise essentially: a central portion (8) effectively corresponding to the layer having the shape and thickness desired for the finished part; an outer portion (11) substantially of same thickness, enclosing at least partly said central portion; cleavable hasps (10) linking said central and outer portions together. |
