3D printing has advanced rapidly, and one of the most exciting features is the ability to print in multiple colors. However, this often involves complications, such as material waste and limitations on the number of colors that can be used. What if you could print color directly onto the object without constantly changing the filament?
What is PolyDye?
This is where a new technology called PolyDye comes into play. Imagine using a common ink cartridge in a 3D printer instead of swapping filaments, similar to those we use in our office printers. This community-created technology allows color to be added to each printed layer efficiently, without losing quality or material.
Advantages of PolyDye
- Waste reduction: The system avoids using additional filament as in traditional purge towers.
- Accessibility: It uses common ink cartridges and translucent filament, making it more affordable.
- Ease of use: No need to change filaments, simplifying the color printing process.
How does it work?
PolyDye requires several steps to take the 3D model from the modeling program to the slicing software. OrcaSlicer is used with a custom profile, and the print instructions are loaded onto an SD card to control the ink cartridge. Once set up, the 3D object prints almost normally, but each layer receives an ink bath to add color.
Current limitations
Although the system could work with any FDM 3D printer, it is currently limited to printers with Marlin firmware due to some specific hardware requirements. The system consists of several parts, including a main board, a secondary board, and a support for the ink cartridge.
How accessible is PolyDye?
The PolyDye system is available for sale in its beta version for $199. However, the necessary files to build the system are openly available in the GitHub project, allowing enthusiasts to build their own version.
Is it worth it?
Although it's a work-in-progress project, the results are impressive, considering it only uses translucent filament and common ink cartridges. With some optimizations, PolyDye could be a viable option for those looking to print in multiple colors in a simpler and more economical way than multi-filament systems.
PolyDye offers a new possibility for 3D printing, simplifying color printing and reducing material waste.
