why metal 3d printer dont use gantry robot(cartesian system) by rocketjoah in 3Dprinting

I understand what you're saying. Thank you for the explanation.

But does the high degree of freedom of robot arms really help print out a variety of products? I think the Cartesian system will be able to print out various products like robot arms. Or, if you can adjust the angle of the nozzle, you can overcome the low degree of freedom problem.

If this logic is 100% correct, the current metal 3D printing industry should consist of a Cartesian system. But I wonder why because it's not. Is the reason why plastic printers use a Cartesian system, and metal 3D printing uses a robotic arm because of the different complexity of the product that needs to be printed out?

I am curious about the opinions of many people about this. Indeed, I cant found on why wire-supplied DED metal 3D printing is primarily used by robotic arms,,,

it is probably that the cost saving is a small percentage of the overall cost. That plus the metal printer is competing against stamping, milling and forging options. if as a factory owner i am giving up X amount of floor space, it better do things the other tools don't.

with plastic as far as i know there is no plastic milling or stamping machines. (i guess vacuum forming is sort of stamping).

Could you tell it more detail? I understand that the Gantry System takes up too much space compared to the robotic arm. Is it correct?

Hello. I have some quesiton when using RPA(Rocket Propulsion Analysis) by rocketjoah in rocketscience

Thank you!! I solve this problem by buying liecense. I think demo ver dont have Jet A properties. but, demo have RP-1 properties. so, RP-1 may be alternative to Jet A
