3D-Printed Rockets NASA
NASA astronauts will soon return to the Moon as part of the Artemis program, and the data there will be used to train them for human exploration of Mars. Additive manufacturing, a tean from NASA, industry, and academia are pioneering methods to 3D print the rocket parts that could one day power these missions. Rapid Analysis and Manufacturing Propulsion Technology project (RAMPT) is currently developing an additive manufacturing technique to 3D print rocket engine parts using metal powder and lasers.

This method consists of blown powder directed energy deposition, and could bring down costs and could significantly cut lead times for producing large, complex engine components like nozzles as well as combustion chambers. Unlike traditional 3d printers, this printing method injects metal powder into a laser-heated pool of molten metal, while the blown powder nozzle and laser optics are integrated into a print-head. A robot then moves this print-head in a pattern determined by a computer building one layer at a time.

  • Self-developed Silent Motherboard: The Ender-3 V2 built-in self-developed silent motherboard, which has stronger anti-interference, faster and more stable motion performance, silent printing and low decibel operation.
  • UL Certified MeanWell Power Supply: Equipped with MeanWell power supply, produced by the listed company with mature technology, meeting all the needs of fast heating and long-time printing. Moreover, the power supply is concealed in the machine, making it much safer.
  • Effortless Filament Feed-in: Ender-3 V2 adds a rotary knob on the extruder, making loading and feeding filament process much easier; Brand new operation UI system and 4.3" smart color screen greatly improve user experience.
  • Resume Printing Function: Can resume printing from the last recorded extruder position after suffering unexpected power outages, saving your time and reducing waste.
  • Carborundum Glass Platform: Enable the hotbed heat up quicker and prints adhere better without the warping. Ultra smoothness even on the first layer.

This technology advancement is significant, as it allows us to produce the most difficult and expensive rocket engine parts for a lower price tag than in the past. Further, it will allow companies within and outside of the aerospace industry to do the same and apply this manufacturing technology to the medical, transportation, and infrastructure industries,” said Drew Hope, manager of NASA’s Game Changing Development Program, which funds the RAMPT project.
