Zero Waste Mode lets Quadro stabilize extrusion pressure inside the model's own infill instead of printing a separate prime tower. On compatible models the tower disappears, and so does the material it would have used. It builds on a printer that already has no color purge.
Quadro doesn't purge colors, because every color has its own toolhead. A small prime tower remains for one reason: pressure. Zero Waste Mode takes that last step.
Why There's a Tower at All
When a toolhead sits idle, the filament in its nozzle stops moving. When it becomes active again, extrusion goes from static to flowing, and the first lines can come out inconsistent. A short priming extrusion stabilizes the pressure before the toolhead returns to the model. On a normal Quadro print, that extrusion is printed into a small tower beside the model. See Why Quadro Doesn't Purge.
What Zero Waste Mode Does
With Zero Waste Mode on, the pressure-stabilizing extrusion goes into the model's infill, the hidden interior structure, instead of into a tower. The material isn't thrown away. It becomes part of the print. The slicer previews it: the infill area is marked, and the tower is gone.
When It Works
Zero Waste Mode works on compatible models, meaning the model has enough infill for the extrusion to go into. A thin shell, a very small part or a print with no infill leaves nowhere to stabilize, and the printer uses the small tower instead. That's why it's a switch, not a default.
What It Changes
- No prime tower. One fewer object on the plate, so more space for the model.
- Less material outside the model. The tower's material goes into the print.
- Less cleanup. Nothing to remove after printing.
Compare that with a single-nozzle printer, where every color change flushes material. See Purge Towers Explained and How Much Filament Does Multicolor Printing Actually Waste?.
Up to 90% Less, and Then Some
Quadro's four-toolhead architecture produces up to 90% less waste than conventional single-nozzle multicolor systems. Zero Waste Mode removes much of what's left. To see how this adds up over many prints, see What Multicolor Waste Costs.
Key Takeaways
- Quadro has no color-clearing purge. A prime tower only stabilizes pressure.
- Zero Waste Mode prints that stabilizing extrusion into the model's infill, so the tower isn't needed.
- It works on compatible models, with enough infill.
- The material becomes part of the print instead of waste.

3. FAQ
What is Zero Waste Mode? A Quadro slicing option that stabilizes extrusion pressure inside the model's infill instead of in a separate prime tower.
Why does Quadro need a prime tower at all? When an idle toolhead becomes active again, extrusion goes from static to flowing, and a short priming extrusion keeps the first lines consistent.
Does Zero Waste Mode work on every model? No. It works on compatible models that have enough infill. Otherwise Quadro uses the small tower.
Is Zero Waste Mode the same as no purge? They are related. Quadro never purges colors because each color has its own toolhead. Zero Waste Mode also removes the pressure-stabilizing tower.
How much waste does Quadro save? Up to 90% less than conventional single-nozzle multicolor systems, and Zero Waste Mode removes the remaining tower on compatible models.
