Whatever Prints your Boat

On September 19–22, 2019, in a period of 72 hours, the University of Maine Advanced Structures and Composites Center produced a complete, seaworthy boat in a single pass with the world’s largest 3D printer (additive manufacturing machine), developed by Ingersoll Machine Tools.  Here is a time lapse video of the entire construction process.

This principle is much simpler and more fundamental than the cloud of confusion and ignorance spread like squid ink by the slavers who prefer a disarmed and dependent population at their mercy.  It goes to the heart of free speech, and we’ve been here before.... [Read More]
