-
Waste Objects
Instead of a dedicated tower, waste objects can be strategically placed on the print bed to serve as purging zones. The printer moves to these locations to perform color changes, depositing excess filament before resuming printing the main object. This approach can be integrated directly into the design of the printed item for functional or aesthetic purposes and is useful when the waste object can be incorporated into the design. An example is printing a phone stand that includes a small, separate base; the color changes can be implemented within this base, eliminating the need for a separate purge tower.
-
Internal Purging
Internal purging strategies involve using the infill of the printed object as a purging zone. During color changes, the printer deposits excess filament within the infill structure, minimizing external waste and utilizing the object’s internal volume. This approach is particularly effective for objects with dense infill patterns where the purged material does not compromise the object’s structural integrity. For example, when printing a solid cube with alternating color layers, the internal infill can be used to purge the nozzle between each color change, minimizing the need for external structures. This ensures the outer visible surfaces have the desired color.
-
Sequential Printing
In some cases, it is possible to print the components separately or sequentially to avoid needing to purge as often.
