So there are may designs out there for DIY Filament extruders which use wasted Filament or pellets. But why dont we use instead of one container which has the pellets inside, a mixing system which contains 5 (or even 6) mixing containers which mixes the pellets in the desired matter to receive a certain color? F.ex. using a big drill bit to transport the colors in the programmed matter (f.ex. 50% magenta and 50% white). You would just had to measure the distance from the extruders output to your hotend to have an offset to know when you need to mix the colors. Just a quick thought, would love to get some feedback to that thought :) ~Straw https://reprap.org/forum/read.php?14,658469,658469#msg-658469 Fri, 09 Oct 2026 00:29:23 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?14,658469,708789#msg-708789 https://reprap.org/forum/read.php?14,658469,708789#msg-708789 You have the MCOR paper lamination machines, which for a while could be bought for under 10k (now 18k).
The Stratasys J750 costs a lot and prints great, but is there a huge demand for it? (given the high cost)

FDM can do full color, in a way: [www.3ders.org]]]> paucus Mechanics Tue, 20 Sep 2016 15:56:50 -0400 https://reprap.org/forum/read.php?14,658469,708743#msg-708743 https://reprap.org/forum/read.php?14,658469,708743#msg-708743
The problem DEFINITELY is the hardware. Show me any hardware capable of full colour (as in, reproduce a photograph full colour) FDM. There is none.]]> n8bot Mechanics Tue, 20 Sep 2016 13:15:24 -0400 https://reprap.org/forum/read.php?14,658469,708583#msg-708583 https://reprap.org/forum/read.php?14,658469,708583#msg-708583 DaGameFace Mechanics Mon, 19 Sep 2016 22:21:06 -0400 https://reprap.org/forum/read.php?14,658469,707444#msg-707444 https://reprap.org/forum/read.php?14,658469,707444#msg-707444 enricodare Mechanics Wed, 14 Sep 2016 11:18:48 -0400 https://reprap.org/forum/read.php?14,658469,706131#msg-706131 https://reprap.org/forum/read.php?14,658469,706131#msg-706131 DaGameFace Mechanics Thu, 08 Sep 2016 17:35:27 -0400 https://reprap.org/forum/read.php?14,658469,685668#msg-685668 https://reprap.org/forum/read.php?14,658469,685668#msg-685668 paucus Mechanics Sun, 10 Jul 2016 18:21:46 -0400 https://reprap.org/forum/read.php?14,658469,664794#msg-664794 https://reprap.org/forum/read.php?14,658469,664794#msg-664794 rklauco Mechanics Tue, 17 May 2016 09:26:32 -0400 https://reprap.org/forum/read.php?14,658469,658570#msg-658570 https://reprap.org/forum/read.php?14,658469,658570#msg-658570 or
you would have 5 or 6 filament screw extruders on the back of a printer
converting pellets to hot polymer(ABS, PLA) (200deg C) and piping this to the printer
nozzle?
What type of flexible piping would handle the temperature and pressure
of the hot polymer and keep it hot to squirt out print head?
or
5 or 6 screw extruders with pellet bins on a X axis I-beam just above print nozzle
and move it at 800mm/sec operating the screw extruders to deliver color polymers
directly to nozzle.
I suppose leadscrew drive on heafty X-Axis glide rails to move around
the 300-400 pound multi-extruder

Is a full color 3D printer really required?

I don't know how polymer (ABS PLA) is colored -- maybe just inject color right where its necessary

I have used a felt tip marker to color natural filiment just before it goes into extruder
to get different light colors.

Good Luck Mr Phelps
