In the fourth video showing the changes in Simplify3D I look at two new features that both rely on one main change – the ability for Simplify3D to attempt varying the extrusion width dynamically.

The first feature, “Variable Extrusion Sizing”, permits you to attempt to print features that might otherwise just not print at all, where the total feature size is very small. I demonstrate that this works to very good effect.

The second feature, “Dynamic Gap Fill”, comes in very handy where you have features that in the past left gaps between perimeters and infill, or between two perimeters on very small features. It fills in these gaps with filament which is extruded at a smaller width that your general settings allow.
