Note: This post covers settings in Cura, and primarily mentions the Prusa i3Mk2, however the concepts outlined here will apply for most printers or other slicers. I have only commented on the settings that I’ve changed from the default settings.
- Layer height: Most of our models are printed at .2 layer height. Some of the smaller, more detailed parts are printed at .1
- Shell thickness: .8 is a good shell thickness (this must be a multiple of the nozzle size)
- Fill density: I use 10% for most models. If the model has thin parts that require strength (for example, door frames), then set it to 25%. Make sure you set the ‘prints after infill’ to ON, otherwise, you will see banding on your model.
- Bottom/top thickness: increase this to at least .8 as this makes sure you have a good solid top and bottom on your model.
- Temp: temperature set for PLA
- Build plate: temperature is increased slightly to help bed adhesion, but this depends on the ambient temperature of the room
- Supports: I always use a brim as it allows checking to see if the Z is at a good height when the print begins. It also helps with adhesion. I sometimes use a raft for delicate tall objects.
- Initial layer linewidth: set to 100%. This is important for parts that connect to other parts, for example the OpenLOCK clips
- Initial layer thickness: this can be set higher when printing at a fine detail like .1. I often set this to .2
