Future CAD will be a combination of the virtual environment and the tactile possibilities of 3D printing. No more plans on paper, no more compatibility problems, no more heavy workstations! We'll all go to mobility, instant creating and visualizing, complex machine items which can be printed and no longer have to be machined! Todays coating technologies will be optimised to use a plastic carrier and to apply the needed coatings to give the strength. Looks amazing, the future!
