Good Afternoon, Our club is very interested in upgrading our extruder- a .35 mm J-Head hot end. We will have multiple printers and we have plans to produce objects in numerous filiments from brick to cellulose to conductive ABS. We REALLY want to know where we can find a singe extruder that is bi or tri color- not dual extruder- a single hot end fed with multiple filiment colors and or types. So if you were a university club that needed to have a large array of printers and extruders ( limit it to the Prusa and Delta for the moment) along wih maximum funcionality what should we get and where can we get it? Thanks for helping us! -UNF3D https://reprap.org/forum/read.php?1,334040,334040#msg-334040 Fri, 11 Sep 2026 13:30:20 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,334040,334239#msg-334239 https://reprap.org/forum/read.php?1,334040,334239#msg-334239
I wired them together at the bottom and top with #14 solid copper wire through the fins...

I am surprised that I did not have any height issues........]]> Hiram General Wed, 02 Apr 2014 20:49:50 -0400 https://reprap.org/forum/read.php?1,334040,334227#msg-334227 https://reprap.org/forum/read.php?1,334040,334227#msg-334227
Water cooling is also very cool.]]> Anonymous User General Wed, 02 Apr 2014 19:56:26 -0400 https://reprap.org/forum/read.php?1,334040,334072#msg-334072 https://reprap.org/forum/read.php?1,334040,334072#msg-334072 multi-filiment extruder]]> UNF3D General Wed, 02 Apr 2014 14:18:31 -0400 https://reprap.org/forum/read.php?1,334040,334053#msg-334053 https://reprap.org/forum/read.php?1,334040,334053#msg-334053 UNF3D General Wed, 02 Apr 2014 13:43:31 -0400 https://reprap.org/forum/read.php?1,334040,334042#msg-334042 https://reprap.org/forum/read.php?1,334040,334042#msg-334042
Are you printing single objects in multiple filaments? Or do you want to be able to just use multiple filaments (ie. print a brick in brick then a circuit in conductive ABS)?

PS. Conductive ABS is a HUGE pain to use.]]> gmh39 General Wed, 02 Apr 2014 13:22:03 -0400 https://reprap.org/forum/read.php?1,334040,334040#msg-334040 https://reprap.org/forum/read.php?1,334040,334040#msg-334040
