Rocket engines are great for generating thrust from fire and fury, but they are also difficult to manufacture. They need high-strength materials that can withstand the high temperatures involved. [Integza]However, for a long time, he has been trying to 3D print a working rocket engine for himself.His latest attempt involves Print aerospike design with metal.
The project relies on a special metal-impregnated 3D printer filament. The part can be printed with an ordinary 3D printer, and then only the metal is left after firing.The filament may be rough, so [Integza] Use ruby nozzles to process metal impregnated materials. The processed materials need to undergo a medium-temperature “degreasing” stage in the kiln to remove the plastic, and then undergo a high-temperature sintering process to bond the remaining metal particles into a desired continuous whole. This process works well for bronze, but it is a bit tricky for steel.
Equipped with steel gas nail rocket nozzle, [Integza] Try to use these parts with the 3D printed rocket fuel we have seen before.This configuration does produce some thrust and lasts longer than most [Integza]The previous efforts, although still succumbed to the intense heat of the rocket exhaust.
However, in general, this is a good example of what is needed to print steel parts at home. You need a high-quality 3D printer, a ruby nozzle and a controllable furnace, but it can be done. If you manage to print something great, please leave us a message. Video after the break.
