Summary

The Diamond Hotend kit by RepRap.me

This is an OpenSCAD script which holds a mock-up of the metal parts of the Diamond Hotend.

The script also holds routines to generate the structure (also denoted Cooling Shield) needed for appropriate cooling of the Diamond Hotend's three E3D HeatSinks using by a single high-output 50 mm fan.

Furthermore it has an option for a 5015 blower pendant to allow for active cooling of the printed material.
Enable this by setting:
blower_enable = true;

diamond_metal_parts_only.stl
Metal parts mock up made for the purpose of subtraction from your custom design.
This part is made with the scad script by defining:
assembled = false;
metalPartsOnly = false;

The above configurations have been exported into STL-files.
Please feel free to fetch the OpenSCAD script and make as many derivates to fit your printer(s) as you like, but please keep a reference to this thing.

For further information please visit http://reprap.org/wiki/Diamond_Hotend
or http://reprap.me/extruder/diamond-hotend.html

Basics of the construction:

Diamond_Hotend page on reprap org has a link to Diamond_Nozzle.pdf with drawings and specification of distances.

Each M6 mounting hole for cooling towers are leaning out 28 degrees from the centre and are spaced 120 degrees apart.

From the origin (the point where all the lines meet) there is a distance of 24 mm to the beginning of each M6 threaded hole (which itself is 6 mm deep measured from the most distant point on the upper surface)

Dimensions of the E3D LiteV6 can be found on the E3D homepage.

Of course the diamond_hotend_assembly.scad also contains all this information (if you can decode it) :-)

FAQ:
Q: is there a nozzle .stl available?

A: Not really -but if you

  • download and install the latest version of OpenSCAD
  • open "diamond_hotend_assembly.scad"
  • set "metalPartsOnly = true;" on line 14
  • add "//" on line 87 so that it reads "//coldend();"
  • hit F6 to render and click "File"-"Export"-"Export as STL..."

then you can generate your own "nozzle.stl" :)

  • Or you could just take a look at "diamond_cooler_metal_parts_only.stl"

Hi, is possible to have all quote for redraw the hotend?
thanks

Hi friend... You have this in solidworks format ?

Any ideas on how to use the Z probe holder?

What size fan mounts on top of this?

Stuart

i improve the diamond hotend it can go up to 5 filaments and have a cap. so you can change the tip of the nouse and for leaning it will be esai

You should try posting this at www.facebook.com/groups/diamondhotend/
There are already several design ideas.. :)

This comment has been deleted.

Can i use this as a dual? Does a tube and filament have to be on all 3 hotend?
or can i just set it up for 2 hotends?

Yes, you need all three to be loaded, you do not however need all three filaments to extrude

Yeah, I found that out the hard way.. lol

Can this fit on a Rostock MAX v2?

I am not familiar with the specifics that particular printer, but you should be able to further develop some of the designs here on Thingiverse in order to make a fit.

well thanks very kind

hello I wanted to know if the file in question is based on heat sinks E3D V6 long or short, or indifferent? thank you

kharar - in reply to Max68

It was made with the standard E3D-v6 and E3D-Lite6 in mind :)

Does anyone have a set of technical drawings for the hotend that I could look at to design a mount for the Rigidbot?

I have updated the thing description, you may find the answers to your question there

Would it be possible to have the STEP/STP/IGES files of each componnent, it is a far better file type for those who use different cad softwares

Sorry, there are no step files because the source code is written in OpenSCAD. You could render and export each component to the CSG format if you wish, I guess this is the closest one can get...

FreeCAD can turn OpenSCAD source into STEP - pretty painless actually

what is the tobera? how is this assembled for the hot end? or, is it part of the blower fan? I am in the process of trying to uild one of a delta, and I can't see how the hole in the center of the tobera lines up to anything in particular. Could you help clarify, or show a pic? thanks!

Tobera is the nozzle part of the blower fan solution, the hole lines up with a hole in the blower plate which is currently included in the diamond_cooler_shield_blower.stl
:)

Yes, if someone designs a way to mount it in the Lulzbot Mini... That shouldnt be too hard.

Can this be installed on the Lulzbot Mini?

Anxiously waiting for mine to ship - can't wait !!
