The use of 3D printing technology for space exploration has grown to be quite a common occurrence. NASA has recently claimed to use specially formulated 3D printed ceramics to create their spaceships, while Made In Space and Enterprise In Space launched a project to develop an eight-foot-long, 1,000-pound 3D printed satellite. Suffice it to say, additive manufacturing has led to a number of space-driven innovations, but none of these spacecraft or satellites have used 3D printed fuel to get there…
That’s right, 3D printed fuel. Which is exactly what the Singapore-based startup Gilmour Space Technologies utilized to successfully launch their self-made RASTA rocket into sub-orbit. This proprietary 3D printed fuel was developed by a seven-person research team at the Singapore University of Technology and Design (SUTD) campus, which is where Gilmour Space Technologies’ office is located. The startup was founded by Adam and Michelle Gilmour, a married couple who left their careers in banking behind to venture into rocket-launch services.
The 3D printed fuel is the culmination of two combined materials, which the company claims dramatically reduces the overall cost of rocket launches. Along with this so-called “secret sauce” that was formulated to power their self-made rocket, the team also designed a patent-pending 3D printer prototype, which was developed to print the multiple materials that make up their unique rocket fuel concoction because, noted Michelle Gilmour, “Our proprietary rocket fuel cannot be printed with existing 3D printers.”
The startup was formed through the National Additive Manufacturing Innovation Cluster, which was developed last September by the SPRING Singapore and the National Research Foundation, which reportedly funded Gilmour Space Technologies with a “six-figure” sum of money. As you can tell, there’s a lot of undisclosed information about the technology developed by the Singapore-based startup, but they did admit to building a commercial version of their 3D printer, and over the next 18 months, plan to create 3D printed fuel-powered rockets that are capable of carrying satellites.
“We think the space industry is going through a renaissance. There are more and more uses being developed for space satellites in areas such as earth observation, global communication systems and asteroid mining,” said Michelle Gilmour.
