Colorfabb flexible. When? Any new new?

Recommended Posts

I've had good results with SemiFlex but thats with my modified heater. I was never able to get good prints with the stock feeder and I'm still having issues with Ninjaflex even with my modified heater. I'm not sure there is a good workaround for flexible filaments with bowden style printers.

Yes after a month of seeing that video I was hoping to hear something else. I like flexibles but the color options are quite crapy so far. And for my stuff I need it to have at least 'interesting' colors. Ninjaflex and other are very normal and kinda sad :)

Looks like a good idea, I'd just be concerned what adding all that weight to the head would do. Might be worth looking into beefing up the XY rods, adding bigger bearings as well. We have an old MakerBot Replicator that I plan on modifiying with an E3D hotend and gear feeder. The XY stage on the makerbot is more rigid but cant handle the same sort of acceleration/speed the Ultimaker can.

So it seems it's the replacement of XT... filling the gap between PLA & ABS.

looks like if you need real temperature resistance you still go for ABS, but if you don't want to work with ABS or 85C glass transition temp is ok for you it might be nice, I'll give it a try anyhow soon. Wondering mostly if the layer adhesion is ok, as that gave me the most issues with XT.

It's still not cheap, but at least a lot more reasonable priced than the crazy expensive XT.

I was lucky enough to try a spool of red last night.

**Referring to colored XT bellow

I like it better than XT. No burn marks so far. :D

Retraction... I guess I still need to figure it out a bit...

The print finish is great, between XT and PLA-PHA, Similar flexibility compared to XT and better layer adhesion.

I had to print at lower fan speed otherwise it was making some hair and had some spacing between lines. Was printing around 230-235°C, 0.15mm LH, 50mm/s.

nGen Red vs Green PLA-PHA

If you need a high toughness and impact strength comparable with ABS, XT is still a bit better.

But as you can see in the comparison chart (http://ngen.colorfabb.com/why/), it has the best properties of other materials in one filament.

It prints great, and for you @Arjan, it has indeed a better layer adhesion then XT.

Below a picture of nGen transparent, layer height .25mm, 0.5 nozzle, single wall, 230C, 50mm/s, 50% fan:

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
