Make a Brass Hot-End Nozzle for 3D Printing

Low quality 3d printing nozzles are often the ones that prevents your model from being printed as perfectly as they should. In this video I am gonna show you how to machine your own hot-end nozzle on a budged.

Designing a Nozzle (3d Software)

- let start this project by drawing it in a solidworks. This is just a quick preview of how the model was made, so if you are interested in having a solidworks file, contact me and I will send you a copy of a file.

- I also attached the drawings of that model which are linked below: https://drive.google.com/file/d/0BzjScN4T6AbAMzdod0ZFZGVIbnM/view

- Here are some renderings of a model and I hope it wont be much different after being machined :)

Cutting Down a Piece to Work With

-I chose brass as a material due to its good machining properties and it is commonly available in any local shops as a hexagon rod (2 meters in length) for around 5-10 €.

- Cutting down a 20 mm section will be just right to start machining it on a lathe.

Cuthing the Throat and Conus

-Lets narrow down a piece to diameter of 6 mm and make a 15 ° chamfer for easier thread making.

- Turn the piece around and set your lathe to cut at 45 ° angle and mill it down so there will be approximately 1 mm space around the 0.3 mm hole.

Drilling the Holes and Cutting M6 Thread

- Now comes the hard part. Drilling with a 0.3 mm bits is very precise job so take your time and do it slowly and accurately.

- continue on the other side with 2mm bit and 1 mm bit for smoother transition.

- Finally, cut the M6 thread and our nozzle is finished. I cut the thread with so called 'die holder' inspired by Clickspring.

Finished Nozzle

-It really wasn't so hard to machine the nozzle as I taught it would be and I definitely recommend doing it to anyone who wants to improve their 3d printing quality as well as a machining skills.

Testing the nozzle will be up soon so stay tuned and don’t forget to check out the youtube video of making the nozzle.
