3D manifacture in rocket system
Global Nominee
3D manifacture in rocket system received a Global Nomination.
Design a rocket that could be built in place inside one of the four bays of the Vehicle Assembly Building (VAB) at Kennedy Space Center, which is 525 ft (160 m) tall. Utilize additive manufacturing (aka 3D printing) where possible, considering which materials might be able to be used and which ones may have to be brought in already manufactured.
Additive manufacturing, or 3-D printing, is a key technology for enhancing space vehicle designs and manufacturing and enabling more affordable exploration missions. ( the future industrial revolution)

( printed rocket parts )
* The parts that can be printed 3D its turbo pump , injectors and valves , which represents 75% of engine parts , prefer to use copper material in the printing of what has proved its strength to repel the temperature required and the pressure that results from the engines,all of them has been testing together , the success of turbine give 600 horsepower and fuel pump produced 225,000 pounds of thrust using methane gas, which makes complex engines simpler and more efficient.
*liquid oxygen reacts with any organic substances with potentially dangerous results. For this reason, metal tanks have been used.
To maintain a great advantage in mass ratio aluminum-lithium alloys are used .
*Structural components also can be manufactured with 3D additive manufacture just we need .to make some changes to adjust the printing device according to our requirements.
For the lowest propellant tank mass*
Aluminum alloys are the best choice that can be done by 3D
Manufacturing. Any improvement in the efficiency of tanks
Must lie in the direction of thinner walls .use carbon fiber composites .
*For nozzles special care is needed to manufacture them in 3D .Manufacturing nozzles with 3D provide us great convenience, we can get rid of problems during the welding.

(MX3D)
The MX3D robot can print with metals, such as steel, stainless steel, aluminium, bronze or copper without the need for support-structures .
Developing software, parameters and printing strategies for the different kinds of 3D printable ‘lines’.
3D printing like this is still unexplored territory and leads to a new form language that is not bound by additive layers. This method makes it possible to create 3D objects in almost any size and shape. And the technology is more cost effective and scalable than current 3D printing methods.
We can use the "3D print Arms" to print the whole things in the VAB . By more than one method:
The arm could be attached to helix shape in the high bay and move through it during the printing process. the helix diameter is bigger than the maximum diameter in the rocket.
(or) . A tube attached to the roof of the building holds the arm at its end , and moves from down to up during the printing process by a suitable hydraulic system .
(or) . The arm could be attached to the rocket to decrease the space needed to create it.
The problem we face here is that : the print won't be smooth enough , so the drag of the rocket increases , we want more powerful propulsion system (more thrust) that means more fuel and engines is required . ( means more money & effort & time ,......).
We can solve this by : making better surface finish , improve the arm quality .
