Multi color printing

[Fixx]

I'm thinking just get the Diamond Nozzle($30) and source other think for cheaper. Like this heatsink:http://www.banggood.com/3D-Printer-J...-p-972465.html and find an appropriate heat-break($4) for it. Slightly stretch(7mm heatsink lentght difference) and print the Diamond Shield for this heatsink. Get a fan, heating element, thermistor, bowden tubes then you're done for hotend section. Will total for $70(estimated).

I don't know if they will fit, I'm just thinking.

True - I could do that - but I just bought the kit - it's so hit and miss getting the parts out of China. I ordered my 300X200mm heat bed from Reprap.me and they were great to deal with.

our board is a atmel 8 bit board as arduino mega ?

just to know for the modifications on the firmware

Thanks Bolson

Anybody as seen that ?

Yeah i did, i was a bit exceptical on the precission required to align the sheet and the figure... also you need to generate the printed sheet somehow.... not sure how much hardware and investment is required here, nor the "lifespan" of the printed surface once in the media (air, sun, temp changes, whatever)

This might be useful for making a multi coloured print http://www.i3dinno.com/easywelder-en-p186486.html

I just wanted to keep you informed.
I have not already received all the material needed, few arrive from china (Mk8 drive gear, 4 mm Push it, 4 mm ptfe).
I bought 2 E3D V6 extruder (1 for the 4 colors and 1 for the support or hight temp material)
E3D V6 seems to be a very good extruder but not sure for this project.
I read on the E3D guide that it is not advised to retract the filamant more than 2 mm, you can cause jams (I think it is because there is no ptfe in all the heat break, only on the first milimeters on the opposite side of the heat chamber).
(but the 4 colors system works with big (few centimeters) retraction at all changement of color.)

So I must change the 4 colors extruder or create a special heat chamber.
The less complicated is to change the extruder

SAO sorry to hear you already bought the E3D V6, did you know that they now have a lite version which is much cheaper and by all reviews just as good, and has the full PTFE liner. Only negative is max temp of 240-250.

If it all gets too hard to DIY then try one of these http://ordsolutions.com/our-3d-printers/rova3d/
