A New Fix for Waste in Multicolor FDM Printing: The AtomForm 12-Nozzle System

Multicolor FDM printing is notorious for the filament waste that piles up during color transitions. Every color change burns through meters of filament just to purge the previous material left in the nozzle. AtomForm’s new 12-nozzle system reduces this transition waste by up to 90 percent, crossing an important efficiency threshold in multicolor FDM printing.

12 Nozzles, 12 Colors, Zero Transition Waste

Current multicolor FDM systems (such as AMS and MMU) work through a single nozzle. When the filament changes, the previous color sitting in the nozzle has to be purged. In AtomForm’s architecture each color has its own nozzle, so this waste disappears entirely. By using multiple nozzles at once, the system can even produce blended-color surfaces and gradient transitions.

Why Does It Matter?

Waste ratios are often overlooked when calculating the cost of multicolor prints. On a model with five or six colors, the purge flushes performed on every layer can increase total filament consumption by 30-40 percent. Because AtomForm’s system eliminates this flushing process entirely, both material waste and print time go down.

According to the company, this efficiency gain will make multicolor printing more accessible, especially in the education, prototyping and hobby segments. Separate nozzles also make it easier to combine different material types (PLA, PETG, TPU) in the same print.

The Future of Multicolor FDM Printing

AtomForm’s move tackles the biggest operational problem in multicolor FDM printing head-on. The one-filament-per-nozzle principle drives color-transition waste down to zero while also making it practical to use different materials in the same part. For example, a main body in PLA and a flexible grip in TPU can be combined in a single print.

Interest in multicolor FDM printing keeps growing in industrial prototyping and low-volume production.
