For the Fall of 2020, the Bray Lab PAL Machine Shop will be operating as a job shop.

Uploading Files

Please upload:

  1. A photo of your part (.png or .jpeg)
  2. A part file. Typically we require a .dxf or .stl file.
    You are welcome to submit both if you are uncertain.

Typical rule for deciding between .dxf or .stl file:

Upload a .DXF file for parts that can be described with a 2D profile and thickness.

Upload a .STL file for parts that have complex 3D geometries.

Machines and Part File Types

We use different file types with different machines.
.dxf file parts can be made the fastest

Machine File Type
3D Printers .stl
Laser Cutters .dxf or .ai
Shopbot CNC Router .dxf or .stl
