I visited 3D printing day at colorFabb yesterday evening. They had two production lines operational and explained how the production process worked. They showed quality measures they take and what makes them different from other filament manufacturers.
In their 3D printing studio there where printers from different brands one of them was a CEL Robox. The sad thing was that every printer was printing with their new NGEN filament except the Robox, which was switched off, looking sad in the corner. This was not a big event, about 30 - 40 people when I was at colorFabb, still I think this is bad marketing for CEL. So next time as partner of colorFabb let the Robox print. 🙂
So now I like to do some tests with the samples I got. The orange and black filaments are colorFabb_XT so I can use the filament settings from Automaker.
NGEN
I have two samples of NGEN. NGEN clear and NGEN dark green.
This is the info I got from colorFabb (you can find it at the tips and tricks tab for the filament).
At colorFabb we have a well equipped 3d printing studio with a lot of popular 3d printers. We know our materials will give you excellent results and to help you get these results here are tips and trick for using colorFabb 3d printing filament.
Adviced 3d printing temperature:
220-240CAdviced 3d print speed:
40 - 70 mm/sAdvised Heated bed
75-85CBuild platform
nGen gives best results on a heated build platform, 75C to about 85C is usually needed for proper adhesion to a glass plate.
Printing on a cold bed is possible but you’ll need some adhesion tools to minimize warping. 3DLac, buildTak or 3DEeze can do the trick.I made custom filament settings, a first guess based on this information.
Bed: 75 C
Bed (1st layer): 80 C
Nozzle (1st layer): 235 C
Nozzle: 230 C
Ambient: 35 C
Filament: 1.75 mm
Filament multiplier: 0.95
Feed rate multiplier: 1.00December 4, 2015 at 6:02 pm #24680NGen should be printable with the same settings as XT. I just got four reels of it and I will be testing it soon.
I operate two Betas and four Production Robox.
I am the US/Canada Technical Support engineer for the Robox.
www.hudsondesignlabs.comDecember 4, 2015 at 9:10 pm #24687So what’s the advantage of NGen over XT? How do those two differ? I just purchased 4.4 kg of XT… :/
December 5, 2015 at 2:48 pm #24695They claim that it needs a lower temperature, has higher heat resistance, better dimensional stability/accuracy, better durability along with potentially an improved appearance (It looks slightly shiny?) so that it yields nicer looking, more useful prints.
I don’t think they are claiming any single revolutionary advantage, just that they think it is all-round good stuff.
They aren’t offering it in the extra-large reels yet, so XT can probably still claim a noticeable price advantage over it.

December 5, 2015 at 5:03 pm #24699This is exactly the question I asked at ColorFabb. They made this filament more as a replacement of PLA. PLA is biodegradable which results in a degrade in technical quality. Low cost PLA becomes so brittle that you can’t even print with it after a some time. Some users on this forum already had this problem. (Self destructing filament)
The main advantage is the broad temperature range you can use during print. Not all 3D printers have a good nozzle temperature control. Another advantage is the high glass temperature. Models printed with NGEN should last longer than PLA according to ColorFabb. NGEN is better at overhangs than PLA. NGEN is easier to print with than XT. XT is stronger than NGEN.
I did not yet had time to test it. yet I like to compare a PLA real model with NGEN and XT and Woody.
December 7, 2015 at 1:32 pm #24708Was shelf life brought up at all ?
December 7, 2015 at 2:41 pm #24709Self life was nog brought up. I dropped the question at colorFabb. I also requested if they can test the filament on the Robox. ColorFabb told me during the visit that customers can contact them if they have problems with printing colorFabb filaments.
December 8, 2015 at 4:08 pm #24724I did some test prints with the NGEN Clear material. With a 40 % fill it results in a nice frosted look.
Printing a piece at 100% fill to see the difference.

We got lots of nGen samples to test, it is very close in most properties to XT. General opinion in the office is that it is easier to get good results and XT was already very easy to use.

For official support please visit www.cel-robox.com/support/ and create a ticketDecember 11, 2015 at 11:35 pm #24879This plastic gives very good results,
but using the adjustment “fine mode”
the extruder began to slide (on the 2nd layer)/ plastic stuck in the headPerhaps this plastic should not be heated for too long time?
but in fine mode the plastic move very slowly, it deteriorates?
and hangs in the print headidea should be checked
December 24, 2015 at 1:53 pm #25198I’ve just received some nGen.
Printing it with a copy of the cel XT profile, I’m running into a problem where it seems to run out of filament as it goes along, with the start of an extrusion looking fine but by the end laying down only a small portion of what it should.

The second print while having enough material, started lifting off the bed from both ends as if curling from a rectangle into a banana until it completely detached itself and started air-printing. It is a challenging design for adhesion so I think I’ll have to try brim next, but it might need a bit more bed temp as well?
