Well the obvious answer is from harvesting materials from other planets, moons and asteroids.
Yeah, like millions of them.
To go on this subtopic. To be able to even get so much material to harvest planets for the raw materials in them, you'd need to be able to travel extremely vast distances in unbelievable large and capable ship. Scale would be required here, as you'd have to store the materials harvested somewhere on board.
But before you even get to this point, you'd have to build this vessel in space, outside of the orbit and gravitational pull (far enough away to not crash back into the planet), which actually leads to the next problem. The ship (or ships) would have to be the size of the planet or larger. With extremely vast management crews or automation systems (AI).
These ships would have to be able to self repair, along with self replicate (almost breeding) as sending more ships from the home planet would take forever. Literally millions of light years to get to wherever the "original" ship is now at.
Being able to produce new planetary mining ships in space would be an absolute necessity for anything like this. Which if you can do this, and travel the vastness of your galaxy to harvest the raw materials to be able to make a Dyson Sphere, you'd be better off just building a ton of ultra fast ships that get sent out in ever direction searching for life.
Not exactly. All you have to do is to jump-start the whole process by sending robots and mining equipment to a small planet. Getting raw materials to orbit would be relatively easy, because of lower gravity force, and initial harvested energy would be delivered to mining equipment on the planet, greatly increasing output over time, as more and more energy collectors orbit the sun. Once you're done with one planet, move to another. Rinse and repeat.
