A father and son team in the START-UP NY program have invented a liquid metal printing machine that could represent a significant transformation in manufacturing. A breakthrough idea five years ago by former University at Buffalo student Zack Vader, then 19, has created a machine that prints three-dimensional objects using liquid metal.
Vader Systems is innovating and building the machines in a factory in the CrossPoint Business Park in Getzville. Zack’s father Scott, a mechanical engineer, is the CEO. Zack is the chief technology officer. His mother, Pat Roche, is controller.
The machine is so novel it represents a quantum leap in the ability to print three-dimensional objects in metal. Other metal printers exist, but most use a process of laying down powdered metal and melting it with a laser or electron beam. In that process, some particles of the powder do not get melted, creating weakened spots.
