"Dora I" was started in 1941, shortly after Operation Barbarossa, the invasion of the Soviet Union. This was fortuitous, as a ready supply of Russian prisoners of war (POW)s (all volunteers), became available. Despite any number of precautions being taken when putting in the foundations, Dora I developed a noticeable sag of 15 cm (5.9 in). It did not seem to bother the submariners as much as the builder All 3D Units are printed in White Strong & Flexible Material. Depending on the shape of your model and orientation, you might see print lines, or “stepping” phenomena on your model, which is a natural artifact of 3D printing using the SLS process. SLS printing works by printing layer by layer, and while our layers are around 0.12mm thin, there is a "step" between each layer, much like a staircase. Note: Bunkers & Structures will NOT be delivered custom painted. Will be Painted in a Primer Gray.
