What is infill in 3D printing and is it necessary?
Your 3D prints probably don't need to be rock solid, but what goes inside them still matters. You may have noticed a weird web of lines inside 3D-printed models.
AI Summary
In FDM or FFF 3D printing, the interior of a model is usually not solid plastic. Instead, a web of lines—called infill—fills the space inside the outer shell. This infill pattern can vary in density and design, affecting the print’s strength, weight, and material usage. The choice of infill pattern and percentage determines how much support the printed part has while keeping material costs lower.
