Triangles
The Lines infill pattern differ from the others in that the line orientation is alternated every
other layer. All the examples show a 20% infill density.
You're probably wondering which infill pattern is "best". I wish I could go into that, but I've
been unable to locate any studies that cover the topic in any depth. If I were asked to provide a
recommendation for a good structural pattern I would probably pick the Triangles option. It offers a
good internal structure for most infill densities that I've used it with.
Skirt and Brim – This is a new option that appears with the Intermediate and Advanced
setting levels. The Skirt option is used one of two ways. First, it can be used to "prime" the hot end
with filament before the actual part itself begins to print. You may notice that your hot end may
"drool" filament while the bed is heating up and the hot end has already reached temperature. This is
perfectly normal. However, without some kind of priming action, early features of your part may not
print properly. The Skirt solves this. Secondly, the Skirt can become a Brim if the Distance from
Object setting is set to zero. What this does is make sure that the skirt is physically connects to the
part, becoming a brim. This can be handy when you're printing a small part and you're having bed
adhesion issues and you don't want to have to use a raft. Later on in the Advanced settings section,
you'll see more options on how you can tweak the Skirt and Brim settings.
Support Material – With the Intermediate and Advanced setting levels, you get more control
over how the support material for your part is generated.
The new option here is called Support Type and allows you to choose a LINES or GRID
pattern for the support material. When I printed the support example, I used the LINES mode as that is
the default for the Simple settings mode. Looking down on it from above, this is what the LINES
support material pattern looked like for that print.
