Prints with curves and holes

“

- A 3D print is born as a computer model. You can make that model as complicated and detailed as you want. However, the intermediate file formats that get created during the CAD and slicing process, as well as the hot plastic flowing out the nozzle may not be able to retain all that complexity. Finding the right balance between the essentially infinite accuracy of a computer model and a plastic part is a little subtle. A print with curves and holes has particular issues. And this movie will focus on how to model them in enough detail, but not so much detail as to create unexpected side effects. To tackle the simplest issue first, if you have a ten millimeter diameter peg, you'll need a slightly larger hole for it to fit into. Precisely how much larger depends on the printer, the material, and the settings you're using. If you need pieces to fit together precisely, you may want to test your printer by printing the same…
