Preparing the file for the 3D StrataSys printer

.stl File Format

.stl files represent solid objects by means of triangles. .stl files range from 10k to 10Mbs.

Create an .stl file by using SolidWorks, ProEngineer, IronCAD, or AutoCAD.

Your .stl file, must be "watertight". i.e. no surface openings or leaks. This means no unclosed surfaces or exporting using DXF.To generate a proper .stl file, you need to use "solids" .

Note that: FormZ.stl files are NOT reliable.

Bring your .stl files to the rapid prototype lab to put on the AutoGen software.

Try to limit the detail of your object. For example, the more precise of a rounded curve you make on a cylinder, the larger the size of the file, and the more computations the FDM machine requires, which may either cause problems or add to processing time.

The Plate on the Strata Sys machine is about 8 x 14 inches, Please make sure your part is not larger than that.

Costs

Cost is a function of the manufacturing time and the amount of thermoplastic used. these are proportional to the volume and complexity of the part used.

The cost for using the FDM machine in the Rapid Prototype Lab is $13 per cubic inch. The cost of most parts is usually under $50.
