Do filament spool return programs actually work, or does shipping empty spools back cost more than simply making new ones?

In this episode of the Slant 3D Podcast, Gabe breaks down the economics behind filament spool return programs after 3D Fuel introduced its Farm Fuel system. We look at the cost of buying new spools, return shipping, processing used spools, environmental tradeoffs, and why collapsible spool designs could make the entire idea much more practical.

We also cover the latest shakeup at Nano Dimension, the accidental release of Prusa Index CAD data, and why hardware companies should expect competitors to reverse engineer their products.

Later, Gabe sits down with Gabriela Trueba, founder and CEO of Womp, to talk about building a new kind of 3D design software. They discuss Womp's roots in 3D printing, signed distance fields, real-time ray tracing, building their own GPU servers, AI-generated 3D models, and making CAD approachable for a completely new generation of designers.
