This version of a D3D is being constructed at the OSE Immersion Training Summer 2018. It is a 14 inch steel frame, two axis supported hot end extruder. Since it was built using supplied parts and extreme manufacturing a focus will be on assembly instructions.

Bill of Materials
Assembly
Reflection
The frame outlines the machine and should be assembled first.
Extruders were assembled from hotend components and 3D printed body pieces.
Supplied axis 3D printed pieces were assembled by teams with just enough for participants. It seems a surplus should be included to account for lost and broken pieces.
Preassembled carriage pieces required force for insertion of the rods. It seems that 3D printed parts could benefit from labeling to reduce mistakes during assembly and time.
Holes for the axis and control panel set the orientation of the frame and could also be labeled during production.
Extreme documentation requires actual documentation, while this seems arduous it natural part of many fields. In sessions meant to cover documentation of the machines it seems a method of encouraging of taking and sharing notes or full on documentation should be taught first. Lectures may not be very conducive to productive learning, while a hands-on documentation session may connect people with process.
Guide
Extruder
Frame
Axis pieces
Axis assembly and mounting
Extreme Manufacturing
Test-Driven Development
Quality control tests need to be developed for each module.
Future directions
While 3D printing the components for a 3D printer is an interesting experiment, it is not ideal for the mass production of high precision parts. Injection molding is an accessible plastic forming process capable of producing highly standardized parts. This is would be possible with the CNC router and plastic extruder. CAD files for routing would enable integration of this technique.
