Working Notes.
The Open Air design starts with the principal of making a reprap that can build parts significantly bigger than the machine itself. To do this, I am designing a machine that will allow extending an existing piece by building more onto it. Adding new layers to an existing, already finished piece has many implications. The exiting piece must be supported during the add on construction, but it must be mostly outside the main machine to leave the most room possible for the extension. To do this, arms with adjustable clamps will be added that swing horizontally from the sides and extend out to grip securely the existing part. It also means that the bed must be stationary, otherwise the old part extending out would be flopping around with every X and Y movement. It also means that at least one side must be open to allow parts to stick out. I have chosen to have two sides of a cube, plus the corner or edge between them removed, thus the team name "OpenAir".
Stationary bed.
To be able to extend parts outside the framework, the bed must be stationary. This implies that all three axes have to be built into the extruder. The stationary bed will also help modifying the bed to be heated. With the bed not moving, there will be less induced airflow over the exposed heated parts, thus draining less electrical power to keep them heated. It also means that delicate objects being made are not shaken back and forth during layering, so that thinner sections and more unsupported overhangs can be used. Another benefit is that if welding, casting, or other hot metal work requires a controlled atmosphere, since the bed does not slide out it is easier to enclose the whole structure to fill with CO2, Nitrogen, or Argon. ==

What is making the part like?
Text (Motivation)
This is a generic Example project! I, (Example_User) made it because it's cool and Interesting, because I made it with a RepRap, because it is an innovative new RepRap, or because it is elegant or effective. Share and Enjoy! (This page was made using the wiki page Example as a model.)More Descriptive Text
Unlike Other Example project, this is different and better. But we borrowed many elements. Also, we like creating New Example projects.

Well, there's New Example. And Another Example.
Files and Parts
Sub Assemblies and Related
Example/SubAssembly and Related Example. (As a gentle style recommendation, it's good to try to keep all your parts and files on the RepRap wiki rather than scattered around so that Library Staff and Volunteers don't have to write scripts and so on to get stuff back onto the wiki.)
