Aluminum Extrusions

In poking around at 3D printers, I've become more interested in the utility of extruded aluminum for building stuff.  Some two decades ago, I'd rescued some from the scrap tub at work, and although I never used it for anything, it was sure fascinating for some reason.

There's a site 80/20 that sells components.  Their catalog is massive!

The New Generation of 3D Printers

3D printers that are on my radar:

• Cobblebot – multi-material, large format (15” cube); $300 unassembled (additional for heated bed and enclosure), delivery Jan 2015
• RoVa3D – multi-material, multi-color (with multiple nozzles); $1500+ (5-nozzle version is $2600), delivery Feb 2015
• Micro – multi-material, auto-leveling / auto-calibration; $350, delivery, delivery Feb 2015

There’s also the Mod-T, which has a 3D object store, but it’s PLA-only and the printable volume is only slightly larger than the Micro.
