This revolutionary new print head allows you to mix both materials and colors, making it possible to print in a full-color palette when you use CMYK (Cyan, Magenta, Yellow & Key) filaments.Multi-Color & Multi-Material 3D Printing Until now, full-color palette 3D printing has been the ultimate dream for 3D enthusiasts. Some commercial products have been introduced in recent years, but they come with limitations and a high price tag. Few options exist under the $3000 price point. A few multi-filament extruders and advanced add-ons are on the market but they are are limited, for example by mixing just two or three filaments, printing only in PLA, or relying on multiple independent nozzles. The QuadFusion is the first four-filament mixing extruder available on the consumer market. Combining Cyan, Magenta, Yellow & Key (CMYK) filaments allows you to print over 50,000 unique colors. The key filaments can either be Black, White, or Transparent. Using white creates different tints which lighten a color, using black creates shades which darken a color, and using clear adds a degree of transparency and depth. This vase was printed using Red, Blue, Transparent and Black filaments. Technically, there are over 150 different colors within this vase, with a slightly different color on every single layer. With the QuadFusion you can also print with any four compatible filament materials. To be compatible, they should have a similar melting point temperature. This allows you to easily change between materials within your print, or to blend materials together in as many ways as you can imagine. This allows prints to vary in strength, flexibility, and rigidity from one area of the print to another. This allows you to fabricate things in a whole new way, you no longer need to think of your final product as a collection of separate parts to be made out of different materials, but rather it can be one 3D printed part made out of a combination of different materials. A great benefit to both color and material mixing, is that you can get more out of less. Since you can combine colors and materials, you don’t need to keep as many different colors and materials in stock. Additionally, there is no need to worry about painting or post-processing, you just grab your print off the printbed and go. Our New Filaments You can use any standard 1.75mm filament in the QuadFusion Print Head, however if the colors aren’t optimized for color mixing, you may not get a high quality color result, for example if you want to use a key like Black, you need to use a calibrated black because typical black filaments are loaded with carbon pigments which have a very wide particle size and distribution, so what would normally happen is you’re trying to change from black to yellow for example, and you’re going to have to expunge 200mm of filament to get a clear switch between the two, which is a very large waste pillar, and even then you still may have residual specks of black show up in your print. To solve this problem we developed a few lines of filament that would be ideal for color mixing. To do this we calibrated the pigment size and molecular distribution so that it falls within a narrow range, giving you the ability to get controlled mixing ratios, which results in a wider and more pure color palette. The recommended starting material is based primarily on PETG, which comes in two series: ABS-R3 provides opaque material ABSR provides transparent colors and keys. We also offer an opaque PLA line, as well as an opaque Tough 115A line. Versatility We wanted to make the QuadFusion available to as many people as we could, which is why we wanted to make it compatible with a wide range of 3D printers on the market, not just our own. We are going to make a variety of 3D printable mounting plate files available for download to help users get the head mounted as seamlessly as possible. Currently, we have verified mounts for the following 3D printers: MakerBot Replicator 2X, M3D Crane, M3D Promega, and ...
