Small variations in materials, intolerances with the tools are molds that made the part and other issues will lead to small inconsistencies from one part to the next. In this movie will give an overview of these issues. - [Male] A 3D print has a few different sources of error, some of which are shared with traditional manufacturing and some that are peculiar to it. Some issues come from the mini steps in the workflow. A CAD model needs to be converted to STL, then the STL is used to generate instructions for the printer. The commands that come out of that, won't be exactly the same as the ideal model. Then when the printer executes these commands, there will also be variations. And if you run the print on the same printer again, you…
