Tractus3D also takes care of printjobs for large format prints and/or special materials. But it is not only the size or capability to use special materials that counts, the detailing is also very important and this is a good example of it.
This object is a 54cm round reduce for an air ventilation system. The STL file has a low segmentation, and this is clear to see in the picture. Therefore the object is not completely round but has little corners around. In this case it isn't a problem to use it. However the printresolution and detailing of Tractus3D printers are so exact that you will see everything in the printed product.
