ScanningLaser scanning uses a beam of light to trace the contour of an object. The beam then moves on a fraction of a millimeter and records another contour. If the original sculpture was not cut into sections then the probe and the laser would not be able to scan around the legs. The areas where other bits of sculpture are in the way are termed "under-cuts".
SurfacingAbove is also a rendered image of the data collected for the leg.
The files are made of tiny triangles that cover the scanned area. The smaller the triangles then the more data captured. Some of the scanning cannot capture every single point on the object but if there is the tiniest gap in the computer scan then the manufacturing process will not work. This means gaps have to be filled manually. If your object is very detailed then this can take some time.
The final section is about 100 x 40 x 50 centimetres. 5 LOM parts have been glued together and steel rods inserted down the leg to ensure that the parts do not separate. The parts were treated so that they are stable in a range of temperatures and humidities. This is so that the layers do not delaminate (come apart).
