Infills can really change your mechanical properties of your 3d model. It can change the strength, resistance, the finished look, print time and the cost. You will also need to consider infill densities when you are using plastic insert nuts. A 3D model will require dense areas for the insert nuts to bite into.
I found a few great articles recently, one on Infills and the other on Rafts. Rafts can help your model adhere to the build plate and give it a solid foundation.
From the first article from M3Dzone.com, these are the recommended infill settings:
Recommended 3D Print Infill Settings:
- Standard 3D printed Models: 15-50%
- Functional 3D Models: 50-100%
- Figurine & Object prints: 0-15%
- Flexible Models: 1-100%
Strength of Infill Patterns:
- lowest strength = single direction line pattern
- Lower strength = zig zag pattern
- Medium strength = grid pattern, triangular pattern, tri-hexagon pattern
- High strength = cubic pattern, cubic sub-division pattern
