You can infuse vibrant hues into filament during printing by altering the capsule. The design of the capsule features a convenient gap, allowing for effortless exchange. However, it's crucial to exercise gentleness with the exterior during the printing process to avoid causing damage. To achieve this, simply add ink to a sponge and insert it inside the capsule. Keeping the capsule stored in a bag will help maintain its moisture level. Cutting the sponge requires some skill, but mastering this technique can yield stunning multi-colored prints. It's worth noting that prolonged coloring may lead to hotend tube buildup, necessitating regular cleaning. If you appreciate this innovative approach, please show your approval by liking this idea.
