Slic3r in Depth
• 45
◦
/Rotate
- Rotate the selected model around the Z axis, either in
45
◦
increments clockwise or counter-clockwise, or by a given amount.
• Scale - Increase or decrease the size of the printed model.
• Split
- Divides a model which consists of more than one part into it’s
constituent parts, allowing each one to be arranged individually.
The buttons along the bottom of the file list allow you to add, remove,
auto-arrange, or export the models.
• Add
- Opens a file dialog to add a model to the plater, as an alternative
to dropping a file directly.
• Delete/Delete All - Remove one or all models from the plater.
• Autoarrange
- Attempt to arrange the models to give the optimal
layout.
• Export G-code
- Starts slicing the model and produces a G-Code
file.
• Export STL - Save the current set of models as a single STL file.
Cleaning STLs
If the 3D mesh described in the model contains holes, or edges are misaligned
(known as being non-manifold), then Slic3r may have problems working on
it. Slic3r will attempt to fix any problems it can, but some problems are
out of it’s reach. If the application complains that a model cannot be sliced
correctly then there are several options available, and the ones described
here are all free at the time of writing.
FreeCAD
Freecad is a comprehensive, and free, CAD program which
comes with a mesh module, in which repairs to degenerate models can be
made. the following steps outline how a problem model file can be analysed
and repaired.
