NVBOTS, the Boston-based 3D printing startup, has developed a new method of 3D printing metal parts that can use 21 different metals in the same job. The company says the technology is the only one of its kind.

“At our core, NVBOTS is driven to turn ideas into realities, challenge the status quo and deliver on the impossible,” said NVBOTS CEO AJ Perez. “Through the introduction of our ultra-high speed, multi-metal 3D printing technology, we are doing just that. And not only are we disrupting the 3D printing industry, we are solving the toughest problems in additional markets, such as the metal castings sector, which will have a significant impact on medical, automotive and aerospace industries, among others.”

A New Process

3D printing metal isn't easy. You have to have just the right amount of heat required to melt the materials. The way metals conduct heat just further complicates the traditional 3D printing process, which relies on building structurally sound parts layer by layer.

Perez says the new method, which uses electricity to melt metal wire, can be thought of as a high-precision form of welding. The precision comes from a proprietary method of controlling the amount of heat used to produce every single 3-D pixel of a printed part. That provides a level of control over the final quality of the part that is not possible with other techniques, he says.

The NVLABS multi-metal 3D printing technology enables enterprises and Fortune 500 companies to:

  • 3D print with any metal
  • Print multiple metals in the same build
  • Print 10x faster than SLS (selective laser sintering) – and at a significant cost advantage
  • Eliminate the need for molds
  • Reduce labor costs since print jobs can be handled without operator assistance
  • Benefit from accelerated metals testing and engineering of designs
  • Improve efficiencies related to assembly and performance
The Future of Mixing Metals

The technology is still in the development stage. Currently, it can only be used to make small parts. However, Perez says that for anyone looking to make small, high-value stainless-steel and titanium parts, the technology is already a cheaper and more versatile alternative to casting, a common industrial metalworking technique. 

If production can be scaled up, it could replace casting work done in a variety of industries including auto manufacturing, aerospace, luxury goods, and oil and gas.

Using additive manufacturing to inexpensively make a wide variety of reliable parts out of metal would be a boon for many industries, since it would eliminate the cost of building the tools needed to manufacture new and unique parts by conventional means.

The longer-term promise is the ability to print parts with unique properties that “you wouldn’t be able to manufacture any other way,” says Perez. Possible applications include structural parts for things like car or airplane bodies, as well as components of engines, electrical devices, or other machines.

Later this year NVBOTS will launch a program through which industrial partners can participate in research and development aimed at refining the process and further developing the materials palette.
