But in the dark forest, we can make use of a new superpower - home 3D printing. Inspired by replicator machines from various sci-fi stories, these devices allow us to make many things right on our desks, in a way that is similar to how 2D printers spill out documents and photos.

Home or local 3D printing might not be optimal. Per unit cost of thousands of widget coming from plastic factory is often lower than 3D printing. 3D printing is a bit more resilient to supply chain shocks. An instruction from printing is data (and thus censorship resistant).

3D printing is conversion of bits to atoms. Have at least one provider of 3D printing services in the dark forest near you.
