Recently, a team of researchers from Purdue University created a shock wave using 3D printed energetic materials. Energetic materials are a class of material that contains high amounts of stored chemical energy that can be released, and they are used in everything from airbags to explosives. The researchers used an inkjet 3D printer to deposit tiny amounts of the materials, which were then used to create a miniature shock wave. The team described the experiment as one designed to improve the precision and safety of energetic materials, and now Australia’s Defence Science and Technology Group (DST) is also looking at 3D printing as a way to make energetic materials safer and more effective.
Minister for Defence Industry, the Hon. Christopher Pyne MP, announced that the DST will be partnering with industry and academia to develop new technologies that will improve the safety and performance of energetic materials. The group will work with several organizations, including:
- DefendTex Pty Ltd.
- The Royal Melbourne Institute of Technology
- Flinders University
- Cranfield University
3D printing materials such as explosives, propellants and pyrotechnics could not only improve their performance but offer significant logistical and cost benefits in their manufacture, said Pyne.
“This research could lead to the production of advanced weapons systems, which can be tailored for unique performance and purpose,” he said. “It should also allow broader access and more efficient and environmentally friendly manufacturing opportunities to Australian industry providing significant cost savings and competitive advantage for Defence, and industries such as mining construction.”
Through the Cooperative Research Center (CRC) program, AUD$2.6 million has been committed over the next two years.
“These outcomes will have far-reaching civilian and Defence applications and contribute to the development of critical expertise in energetic manufacturing techniques in Australian industry,” said Pyne.
3D printing has been proving itself to be extremely useful for a number of applications in the military, helping servicemen and women in their day-to-day operations in a number of ways. Further research into 3D printing of energetic materials could bring the technology directly onto the battlefield. The military isn’t the only sector in which this research is likely to have an impact, however. It could also result in better car safety features such as airbags, as well as more effective industrial equipment.
