The Diamond Hotend is a single nozzle hotend for 3D printing in multiple colors that requires a minimum of calibration. It allows you to time exactly when and where the color changes and eliminates the problem with oozing nozzles.
The Diamond Hotend allows you to feed three different types of filaments through one nozzle and provides a faster, easier and more precise method of 3D printing, at an affordable price with minimal filament waste.
Benefits of The Diamond Hotend
- Easy calibration
- Better precision
- Prints with 3 different colors
- Minimal filament waste
Features of The Diamond Hotend
The key feature of The Diamond Hotend is the diamond shaped nozzle. We have designed the nozzle to have smallest possible mixing chamber, to make color shifts as fast as possible and to avoid unnecessary filament waste. To ensure rapid nozzle heat up we have constructed the nozzle as compact as possible.
The Diamond Hotend is equipped with high quality heat sinks and heat breaks from E3D Online and is mounted with a 3D printed bracket.
At this time, we have designed mounting brackets and the necessary hardware and firmware upgrades for the bq Prusa i3 and bq wit box 3D printers.
However, the design of the mounting brackets can easily be modified to fit most 3D printers on the market.
We hope that the 3D printing community will collaborate with us in modifying the mounting brackets to fit other 3D printers and encourage everyone to share their bracket designs with us. Any new bracket designs shared with us will be made available for download from our webpage.
We have tested The Diamond Hotend with a variety of filaments including PLA, ABS, HIPS, Nylon, PC and PETG with excellent results.
Electronics
We have many solution for the electronics and it all depends on your 3D printer.
If you replace all your electronics in your 3D printer, we recommend the DUETWIFI. With the DUETWIFI electronics you have all in one board with all the latest features and the best performance.
If you chose the RUMBA you will need to purchase 6pcs StepSticks seperately.
Another solution when replaceing all the electronics is the RADDS v1.5. The RADDS is a 32bit microcontroller and will give you extra performance, which can be necessary for any Delta 3D printer. For the RADDS we recommend to buy 6pcs RAPS128 Stepsticks which have 1/128 microstepping for smooth and quiet printing.
Our cheapest solution when replacing all electronics is the RAMPS + Arduino + Stepper Expander X1 + 6pcs StepSticks.
If you already have the RAMPS electronics on your 3D printer you will only need 1pcs Stepper Expander X1 and 2pcs StepSticks.
StepSticks
We currently have 3 solutions for the stepper motor drivers
- A4988 StepStick - 2A output motor current, 1/32 microstepping
- DRV8825 - 2.2A output motor current, 1/32 microstepping
- RAPS128 - 2.2A output motor current, 1/128 microstepping
Display
We recommend to add a display to the electronics. For the DUETWIFI select the PanelDUE, for the RUMBA or RAMPS select the Full graphic LCD Display and for the RADDS select the RADS LCD Display.
Firmware and hardware upgrades
The Diamond Hotend requires a motherboard that supports tripple extruders. We recommend using the RUMBA motherboard for its easy firmware setup and triple extruder support.
Adapting your existing firmware for use with The Diamond Hotend is easy and only require you to do minor changes.
You can choose to purge the mixing chamber as infill by printing the infill before the outer perimeters, or apply prime towers to purge the mixing chamber with every filament shift. This technique ensures crystal clear printout colors.
We have found Repetier Host to be excellent for preparing triple color prints, because it has proven to work reliably with prime towers.

FAQ
Question: My Diamond Hotend is clogged, how do i clean it?
Answer: Usually if you use a Lite6 heatsink, the clogging is in the bowden tube. Pull out the bowden tube and clean out the tube. Make very sure you will insert the tube fully into the Lite6 heatsink (52mm) or else you will have new clogging inside the heatsink. If the clogging is inside the nozzle, then use a heated 2mm hex key to insert in each heatsink, all the way into the nozzle tip and pull out quickly to remove any plastic. Repeat process until clean. No need to disassembly the heatsinks! If nozzle tip is clogged, use a 0.4mm drill/wire to clean from outside.
Question: My Diamond Hotend is leaking, how do i stop the leak?
Answer: After mounting the heatsinks, heatup the nozzle to 240-250 degree celcius and tighten the heatsink with a plier. If still leaking you can use some PFTE tape or liquid gasket on the heatsink threads. Never use cooling paste on the threads!
