New, Fast, Large 3D Printer

Northwestern's HARP: Full Size Structures in Two Hours
Source:  Northwestern University

 Future of Manufacturing On-Demand
A team at Northwestern University have invented a 3D printer that provides rapid, on-demand manufacturing of large objects in a few hours.  It can be used to make parts for planes, cars, medical devices and more.  The HARP (high area rapid printing) device prints 100 times faster than other 3D printers.  It can create an object the size of a human in 2 hours.

Record Breaking Throughput
Northwestern University says this type of rapid manufacturing on-demand is the future of manufacturing that could put an end to molds and warehouses. The new printer will be commercially available within a year and a half.  It prints both hard, durable parts and elastic objects.  The throughput is record breaking and enables it to manufacture parts on demand.

Non-sticky Liquid & Ultraviolet Light
The printer itself is large:  13 feet tall with a 2.5 sq. foot print bed.  It's a stereolithographic printer that uses ultraviolet light to harden sections of liquid resin, building the structure in layers.  The key to HARP and its rapid flow rate is a non-sticky liquid that removes excessive heat and keeps the resin from sticking to the printer. 3D printing just got a lot larger and faster.  For free Kindle borrows of my "Important Innovations Collection" books, go to amazon.com/author/ekane

VIZR & Smartphone Advanced Display Source: VIZR Heads-Up Display Gadget VIZR is an advanced navigation display that grips to the car dashboard. You put your smartphone on VIZR and it turns your smartphone into a transparent display that lets you navigate and drive while never taking your eyes off the road.  The heads-up display (HUD) uses the same technology that fighter pilots use to stay focused.  The system offers a number of apps to view such as navigational tools like GPS, street maps, traffic conditions and speed. Distracted Driving Over 424,000 drivers are injured yearly by distracted driving.  For instance, by looking back and forth between a screen on the car seat and the road.  This new piece of smart gadget technology is designed to change the dynamic and enable the driver to navigate and keep their eyes on the road for greater driving safety.

US Army Invention - Drone Defense Source:  US Army Drone Netting Device Drone Netting Grenade U.S Army researchers have created a 40 mm grenade to protect the armed forces from menacing, enemy or rogue drones.  The defensive drone grenade takes out the drone with a weighted net. Countermeasure - Net Bagging a Drone The net is spring loaded and ejects from the front of the grenade when it nears the drone target.  The net can be triggered remotely by a person on the ground or automatically by an onboard proximity sensor. Drone Defense The net springs open to 30 feet in diameter.  It traps the drone, causing it to fall to the ground.  Word of this new drone defensive technology has just been released.  For more news stories on important innovations, go to  amazon.com/author/ekane
