Next Offset Solutions will commercialise a 3D printing technology for energetic materials including rocket fuels and pyrotechnics.

Purdue University formed US-based 3D printing spinout called Next Offset Solutions on Thursday to commercialise a system for producing energetic materials.

Next Offset Solutions will advance a 3D printing technology capable of outputting materials with fine geometric features for energetic applications such as solid rocket fuels and pyrotechnics.

The technology applies high-amplitude ultrasonic vibrations to the 3D printing nozzle to yield materials of a similar consistency to clay, moulded in a sticky and semi-fluid state known as viscosity.

Next Offset believes the approach will offer faster and more cost-effective production of energetic materials than conventional methods that achieve precise viscosity by using solvents.

The spinout will initially consider seeking contracts with the US departments of energy and defence but could in time expand beyond energetic materials. Its technology has also been tested on products such as biomedical implants and personalised drugs.

Next Offset’s co-founders include Jeffrey Rhoads, a professor in the School of Mechanical Engineering, and Emre Gunduz, a former research assistant at the same department.
