It is a common misconception that 100% is always the best solution to creating a strong part. While 100% infill will create the strongest possible part, the ratio between printing time and part strength worsens as you increase the infill density, especially after approximately 60%. Selecting 100% is therefore often a waste of time and material in comparison to lower infills.<ref>Alvarez C, Kenny L, Lagos C, Rodrigo F,  & Aizpun, Miguel. (2016).

In other words, if your part will not be facing any mechanical strain, <u>we recommend you select an infill percentage between 5-20%</u>. If strain is expected and strength is required, <u>use 60% at the very most</u>.
