Repeatability in 3D printing

“

- [Instructor] When we see the output of a factory that produces hundreds of thousands of an item, it's easy to think of all of them as identical. However, they won't really be exactly alike. Small variations in materials, in tolerances with the tools and molds that made the part and other issues will lead to small inconsistencies from one part to the next. - 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 many 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 will not be exactly the same as the ideal model. Then, when the printer executes these commands there will also be variations. And if you've run the print on the same printer, again you may have variations from filament Amie conditions and…
