After some light reading into aluminum extrusions and their characteristics, I have to be honest, that with translucent1's clever use of this material in this scanner build, it's clear that the functional design possibilities are endless with this extrusion-type.
This has come at a time where my own conceptual plans on a third build must admit that these extrusions are far superior than a once perceived aluminum pipe & plating design. A more integrated framework that closes-in on precision is really a great achievement. These aluminum structures are so versatile, torsionally strong and light, it only makes sense to construct a framework out of these.
Most of these sections can be cut on a chop saw with a 50-60t carbide blade, it's very similar to working with wood. If you're comfortable working with wood, these will be sized in similar fashion + the benefit of all the accessories pre-configured to mod your own rig. In addition, there's a few websites that have the CAD specs downloadable to your software allowing you to design in 3D drafting before you even buy any parts. Very cool.
Or, if you end up waiting a couple months, you'll likely see more DIY designs employing this framework.
The only drawback is the cost. But I too am looking at the fact that this material allows for high-concept/high quality results if built correctly. --A worthwhile expense, and still far less than a commercial scanning device.
