Pls, do tell about some benefits. It doesn’t have to be some spectacular thing, if it’s just the price, that would be okay for me. But just a step-file, wow, not impressed. :-/

Thanks for your comments

We developed this hotend because we need a open source alternative all metal hotend that can be made in India the easy way at affordable cost with less tools.

We believe the plus are

  • Should be cost very less should be $15 or even less (max not more than $20 with all parts including fan, thermistor, and heating cartridge.)
  • Important things is an Open Design all metal hotend at a license everyone can make, share, remix and sell (most designs are shared only under non commercial or closed license)
  • Should be able make in a DIY CNC mill and a drill, with few tap bits.
  • modification in heatbreak, so you can use plier and screw them without breaking it.
  • Bowden and Direct Drive compatibility - you can use pneumatic fitting for converting it as bowden drive.
  • Don’t need Fan for active cooling, we tried up to PLA@180C without cooling fan, and upto 245C we tried without FAN.
  • No need to 3d printed FAN Mount. 40x40 Fan mounts directly on top of heatsink.
  • If Fan used, fan will also force cool the heatbreak and keep the hotend very cool (because small amount of air flows directly on heatbreak see the rendering image on grabcad.)

Share your thoughts.

Also to note in India the original e3d all metal hotend cost approximately $100 after import duty, shipping, etc…

The Chinese clones are not up to the quality many times.

Why is this easier to make with a flat part like that heatsink? Round would be easier and cheaper… Or just a of the shelf part? Please explain ^^

@VolksTrieb , The heatsink is easier to mill using a DIY CNC, If Round would be easier and cheaper why does the E3D, Prusa nozzle are way costlier. we wanted a affordable alternative to those costly hotend.

Yeah for a DIY mill. But if you have both cnc mill and lathe lathe must be cheaper. Iam speaking of an industrial machining. Not at home in small ammounts :wink:

@VolksTrieb Agree with you
