Basics

Part of the Open Source Digital Fabrication Construction Set
It is essentially a massively scaled up (most likely garage/warehouse sized) D3D Fiberglass Printer
It will also most likely require a Open Source Cleangarage to prevent dust buildup due to the long print time, and unenclosed nature of the giant build area
Also require a heated build chamber...but at room scale
This may seem daunting, but it will provide custom designed, mass produced hulls for the Open Source Watercraft Construction Set
