Procedure for .stl (FDM model)
1. Create a model Make sure the wall
thickness are a min of .07 (1.5mm) and
max volume of 1”^3
2. Check the model iproperites for mass
and volume. (check update if you have
no info) Redesign your part to fit the
volume requirements. (Perhaps make a
derived part that is a scaled version of
your original)
2. Make a .stl file using “file save as”
Procedure for .dxf (CAM model)
1. Create sheet metal part
2. Make flat pattern (6”(y) x 10”(x) Max
Size)
3. Make an .idw of the flat pattern.
4. “File save as” .dxf
5. Open .dxf file in Autocad; place &
note the origin (see example next sheet)
(You will have to “move” the pattern to it’s
new origin) Retain ONLY the tool path and
origin note
6. “Save as” Autocad R12 .dxf
Establish & note the origin
MAX 10”
MAX 6”
Flat Pattern
File save as
Autocad R12 .dxf
