Today I tried to print the first of the vertebrae. When I imported the design into the UP Studio software, the vertebrae appeared incredibly small. I designed the vertebrae to be 1.75 inches in diameter and the main ring is 0.25 inches high, but in the UP Studio software, the design was 1.75mm wide!
I consulted with a more experienced colleague of mine and together, we discovered the problem. UP Studio software cannot distinguish between imperial and metric measurements. It can only read in metric, so when I imported my design in imperial measurement of 1.75 inches, it read it as 1.75mm. I had to convert the design parameters to millimetres in the software I use to design 3D objects and then re-import the file into UP Studio. Finally the design could be printed!
