4.3 Brief give the command for exporting your design
from CAD to the rapid prototyping
machine or 3D printer. (5)
Mostly the file extension for 'The rapid prototyping machine or 3D printer' is "STL".
i.e STereo Lithography i the format for Standard rapid prototyping industry.
Now steps to export an CAD file(.DWG) to ".STL"
For "AutoCAD"
1.The design must be a three-dimensional(3D).
2.Object should be solid.
3.After completion of your object design, type command in AutoCAD command's line
4.Type "DISPSILH" then Set this to "1" (One)
5.Type "ISOLINES" then set this to "0" (Zero)
6.Type "FACETRES" then set this to "10" (Ten), the quality of file indicates this from 0.5 to 10 , Ten is maximum quality.
7.The object should be in positive X-Y-Z octant, if it's not there relocate it.
8.To export use "STLOUT" command then give name for that and save.
There you got the .stl file.
