This model is inspired by titan BT 72-74 from 'Titanfall 2' videogame.
As you can see from the picture, this is a highly articulate model almost entirely made by 3D printed pieces of a total of 48 pieces you will mount by yourself. The red one on the right is the final model, the green one is the prototype.
It is complete of full instruction manual
I was able to print it with a cheap prusa i3 printer, so I'm sure you'll be able to print your Titan in about a week with normal PLA.
See the manual to understand how to build this model!
