Dear colleagues,   I’ve been working for years around the 3D printing universe.   I’ve designed several prototypes: CIVA (2000), UVM (2011), DNR (2012), PTR (2013) and others, all have been studied using the rapid prototyping technology first.   On the way, I realized that this printing process can even be used in certain conditions for the final production. Of course, these conditions must be taken into account in R&D.   Everything is not possible! But there are many advantag
