>Ultimately, InventWood is planning to use wood chips to create structural beams of any dimension that won’t need finishing. “Imagine your I-beams look like this,” Lau said, holding up a sample of Superwood. “They’re beautiful, like walnut, ipe. These are the natural colors. We haven’t stained any of this.”

At least for residential, wood-framed houses, the framing material is delivered pre-cut. Even roofing beams are pre-assembled and delivered in triangles to the construction site.

I'm sure someone can figure out a program that takes a CAD design and plans all the cuts.
