Enabling Support Material
Enabling support material allows your Solidoodle to print overhangs in excess of 45 degrees, which gives you more flexibility in the shapes and objects you can print.
The tradeoff to this is that enabling support material increases the time it takes to print, uses up more plastic, and requires that you take time to remove the support material from your print after its done.
 Enabling Support Material in Skienforge
The support material settings are found in Skienforge under the "Raft" tab, at the very bottom of the options. To enable support material, follow these instructions...
1. Click on the "Raft" tab, and scroll to the bottom to find the Support section.
2. Change "Support Material Choice" to either "Everywhere" or "Exterior Only", depending on your requirements. "Everywhere" is a safe choice.
3. Slice your model up into GCode, and print!
 Enabling Support Material in Slic3r
The support material settings are found in Slic3r under 'Print Settings' and then 'Support Material'. To enable support material, follow these instructions...
1. Check the 'Enable Support Material' box.
2. Change the overhang threshold. This is the angle at which support is enabled for a piece of geometry. Use Repetier-Host to visualise the g-code after making changes.
3. Choose the pattern of infill. Rectilinear is recommended because it peels off more easily.
4. Choose the pattern spacing. A small number gives dense support for overhangs and a large number gives minimal support. The default is 2.5mm.
5. Slice your model up into GCode, and print!
Please note: An additional option can be found under 'Print Setting' > 'Advanced' > 'Support Material'. Setting a percentage here modifies how thick the filament is extruded for support. Setting a value like 80% will make the filament narrower, and potentially easier to break off.
