Once you have the Mattermorph node, head towards the center of the zone and look up to see the crane holding a container-like cabin.
So, make your way toward the top and use the node to destroy the container, then grab the Relocator Cannon.

Once you have the gun, take the tunnel and reach the sealed door, which you must destroy using the Relocator Cannon.
After you unlock the door, you will find the teleporter right next to it. Interact with it to reach the room where the final piece is located.
