The invention concerns a method for manufacturing at least one thin-walled structure (), whereby this structure is built layer by layer by applying successive powder layers extending substantially horizontally and by moving an energy beam over each of these powder layers according to a predetermined pattern so as to make said powder melt and subsequently make it solidify or sinter, such that successive layers connected to each other of said thin-walled structure () are formed which extend according to a horizontal cross section of this thin-walled structure (). According to the method a support structure () is built in layers together with said thin-walled structures () and connected to it such that a rigid unit () is manufactured, whereby after building this unit () layer by layer, at least the thin-walled structures () are annealed in order to at least partly eliminate any stresses present, and whereby both structures are separated from each other.

The invention concerns a method and a device for calibrating at least one scanning system () when producing an object () by additive manufacturing, wherein the coordinates of one or several reference positions are measured in the relative coordinate system of each scanning system (), after which the calibration of each of the scanning systems is adapted starting from the measured coordinates of the reference positions.

The invention concerns an implant for adjusting the position of at least one tissue holder () for soft tissue, whereby this implant can be fixed to bone tissue at a distance from said tissue holder () and has a guide () for an elongate pulling member (), whereby this pulling member () is connected to said tissue holder (), and whereby the implant includes a fixing element () which can be moved between a fixing position in which the pulling member () is clamped by the fixing element () and a free position in which said pulling member () can freely move through said guide (), characterized in that said fixing element () cooperates with a control element () which makes it possible to move this fixing element () between said fixing position and said free position when the implant is attached to said bone tissue and when the implant is covered with soft tissue such as muscle tissue or skin tissue.
