for Enigma plates and placards
Two Rapid prototyping processes used to make parts direct from 3D CAD files:
1) 3D Printing process, a way to make prototype parts by printing them.
2) FDM Titan, innovative Fused Deposition Modeling (FDM) by building them.
#1: 3D Printing process
3D Printing is the New technology that we are using to test Enigma cast parts.
On the left is a photo of the first base part received for the Enigma. Note it has all the holes, bosses and recesses needed for a complete part. All that is left is to tap the holes and apply cyanoacralate.
3D Printing is TAN in color.
Using a different technology, FDM Titan (Fused Deposition Modeling), Stratasys is a company that can produce parts in Polycarbonate (like Lexan). You can see a movie on their web site about this process.
Polycarbonate is white in color.
Enigma Keyboard ....
and Rotor AdvanceBar ....
were produced by Stratasys to compare the two technologies.
With either the 3D printing
or FDM Titan , these underside cutouts and holes come ready to
