# Multicolor 3D Printing Attachments The Diamond Hotend Can Print Many Colors From One Nozzle By Rahul Kalvapalle | Published 2015-04-13 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/hotend References: [gizmag](http://www.gizmag.com/diamondhotend-color-3d-printer-extruder/36950/) & [reprap.me](http://reprap.me/front-page-show/diamond-hotend.html) A group of Danish entrepreneurs have developed a [3D printing extruder unit](https://www.trendhunter.com/trends/fibreseeker-3), dubbed the Diamond Hotend, that can melt three different filaments together and produce items in rainbows of colors. This essentially allows for the printing of multiple colors from a single nozzle. Current hot ends can only use one filament at a time, meaning that 3D printers being used to print in different colors require a unique hot end for each color. This leads to a number of problems. For one, nozzles can damage each other's work if they're not exactly the same height from the work surface. Moreover, the nozzles need to be carefully calibrated and the 3D printer's software has to constantly make corrections to achieve consistent output. By getting rid of these problems, the Diamond Hotend allows for [easier and more widespread use](https://www.trendhunter.com/trends/ultimaker-s6) of [multicolor 3D-printed creations](https://www.trendhunter.com/trends/elegoo-centauri-carbon-2-combo). ## Trend Insights (Trend Hunter) - Score: 4.0/10 - Popularity: 62% | Activity: 51% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What Makes This Trend Stand Out - **Multicolor 3D Printing:** The Diamond Hotend enables the production of items in rainbows of colors from a single nozzle, revolutionizing the multicolor 3D printing industry. ### Sectors Adopting This - **3D Printing:** The Diamond Hotend disrupts the 3D printing industry by eliminating the need for multiple hot ends and enabling easier and more widespread use of multicolor 3D-printed creations. ## Related on Trend Hunter - [Multicolor Printer Filament Modules](https://www.trendhunter.com/trends/filament-module.md) - [12-Nozzle Desktop 3D Printers](https://www.trendhunter.com/trends/palette-300.md) - [Efficient 3D Printing Systems](https://www.trendhunter.com/trends/color-3d-printers.md) - [Aftermarket 3D Printer Controllers](https://www.trendhunter.com/trends/co-print-chromaset.md) - [Multi-Material 3D Printers](https://www.trendhunter.com/trends/multimaterial-3d-printer.md) - [Multi-Head 3D Printers](https://www.trendhunter.com/trends/prusa-xl-multi-material.md) - [Dual-Material 3D Printers](https://www.trendhunter.com/trends/fdm-3d-printers.md) - [Seven-Material 3D Printers](https://www.trendhunter.com/trends/j850-pro.md) - [Cutting-Edge 3D-Printers](https://www.trendhunter.com/trends/snapmaker-u1.md)
