Infill is the structure printed inside of an object.
Infill is the structure printed inside an object. Normal infill percentage is 10-15%. But these are settings that can easily be changed depending on your project needs. We can go as high as 100% (completely solid).
Infill is only applicable for FDM prints. For SLA and SLS prints, parts are printed 100% solid, unless digitally hollowed out.
