For most functional parts, a wall thickness of 1.2mm combined with 20-30% infill density is a good starting point.
Comparing Walls vs. Infill for Strength
Strength Tests and Case Studies
Several tests and case studies have shown that both walls and infill contribute to the overall strength of a print, but in different ways. For example, a print with thin walls and high-density infill may still be strong, but a print with thicker walls and lower-density infill often provides better overall strength for most applications. The key is understanding the specific needs of your print and adjusting accordingly.
When to Prioritize Wall Thickness
In situations where your print will be subject to high stress or mechanical loads, thicker walls are often more beneficial. Parts like brackets, gears, or other mechanical components will benefit from the additional rigidity that thicker walls provide.
When to Prioritize Infill Density
Infill density and pattern become more critical when the print requires balanced internal support. For example, objects that need to maintain shape under compressive forces, like support beams or certain structural components, may benefit more from higher-density infill combined with moderate wall thickness.
