Vader Mk1, an Experimental System for Molten Metal Inkjet 3D Printing

The Vader Mk1 Experimental 3D printer by Vader – a Buffalo, NY, based startup – represents a revolutionary advance in 3D printing — bringing to life new possibilities for metal additive manufacturing. Centered on patent-pending MagnetoJet technology, the Mk1 propels liquefied metal from a 1200°C chamber encased in an electromagnetic field through print nozzles similar to an inkjet printer – allowing full control of the Earth’s most abundant metal, Aluminum.

Its reliance on wire feedstock rather than powders allows the Mk1 to offer significantly reduced operating expenses and dramatically reduced time for near net shape parts. This remarkable step in technology is delivered through a state of the art touchscreen user interface, with access to all process parameters – ideal for research and development applications.

Mk1 Production – Coming 2018

Vader’s production grade Vader Mk1 version, slated for 2018 release, will offer even more: production-stable capability for short run and specialty production items, additional printable materials such as bronze and copper, and advanced touchscreen software that creates an intuitive experience unlike any machine tool on the market.

MagnetoJet

Vader’s patent-pending MagnetoJet technology is based on the study of Magneto Hydro Dynamics (MHD), or more simply: the manipulation of liquid metal through magnetism. MagnetoJet’s extraordinary physics are accomplished by depositing Aluminum wire into an 1200°C ceramic chamber, where it is influenced into a molten state. This molten media is then electromagnetically pulsed – causing a droplet to form and eject with precision from a carefully crafted ceramic nozzle.

The Vader Mk1 delivers 1000 droplets per second with micron level accuracy, while doubling the speed of conventional 3D powder bed metal printers. Aluminum was an intentional first step, but MagnetoJet will evolve to printing additional conductive metals and potentially thousands of printing heads within one machine.

The Mk2 – expected in late 2018 – will contain 10 printing heads and is expected to produce parts 30x faster than the Mk1. The companies goal is for metallic design and manufacturing evolution to be exponentially impacted across all industries.
