Slic3r
• Small perimeters - Meant for holes, islands and fine details, a slower
speed here is recommended.
• External perimeters - A slightly slower value may ensure cleaner
surfaces.
• Infill - As fast as you can without compromising the integrity of the
fill structure. Faster extrusions can break and result in weak spots.
•
Solid infill
- The bottom of the model, and any additional solid
layers is usually slightly slower than infill but faster than perimeters.
•
Top solid infill
- Allow time for the extrusion to cleanly cover
the previous top layers and result in a tidy top surface. The last few
layers should have bridged the infill structure nicely, preparing the
way for a neat finish.
•
Support material
- Generally support structures are quick and dirty,
and so long as the base is adequately supported they can be built as
quickly as they can.
• Bridges - Having the extrusion span distances depends on the
material and cooling. Going too slow will result in sagging, too fast
will result in broken strands. Experimentation is the key here, but
generally bridging runs slower than perimeters.
• Gap fill - Filling in small gaps results in the extruder quickly
oscillating and the resulting shaking and resonance could have a
detrimental affect on the printer. A smaller value here can guard
against this. A setting of zero disables gap filling completely.
• Travel - As fast as your printer will allow in order to minimise ooze.
•
First layer speed
- As mentioned in subsection 2.3, the first layer is
important to lay down correctly, and a slower pace helps enormously.
Setting a value of 50%, or even less, can really help.
Acceleration control
is an advanced setting allowing acceleration
settings for perimeters, infill, bridge, as well as a default setting, to be
made. Deciding which values to set depends on the capabilities of the
machine. Any settings within the firmware may be a good starting point.
