Topic: Taulman 910 Nylon
Have been working on an RC project - have printed 2 prototypes in ABS - 1st was for fit of the pieces - low infill. 2nd was checking tweaks made and as a "working" model - high infill. In actual testing it didn't hold up very well for several reasons, not all of them related to the plastic used...
But anyway, in the quest for something more suitable I ordered a roll of the Taulman 910 Nylon and a roll of ABS based CF filament from another company (will do a proper review of that one later)
The spool the Taulman comes on is TINY! I could not fit it on my regular spool holder (3/4" ID PVC pipe over threaded rod, running on bearings in printed adapters) - I had to use the smaller version from my FT prusa (1/2" ID pipe, also on bearings) and that barely fit - had to remove the adapter from one end, load the spool, then re-install the bearing adapter & nuts that hold it all in place
Calibrations: went as usual - measured and averaged the filament diameter, print calibration cube, tweak settings, etc...
Taulman recommendations:
Extruder: 245-260
Bed: can be either cold, or warmed to 40C with a 50/50mix of PVA glue & water
Retraction: 0.1mm for each 0.1mm of nozzle size (0.4 nozzle would be 0.4mm of retraction) < yeah, right LOL
My actual settings:
Extruder: 249C (E3D v6)
Bed: 52C with a generous application of Aqua Net hairspray (may reduce this a bit after some more experimentation)
Retraction: my normal for ABS = 0.75mm - doubled it to 1.5mm and could stand a little more, but don't want to push it too high and end up with heat creep problems...
the stuff oozes like crazy at 245C, but to get good layer adhesion, I had to bump it up to 249C. increasing retraction has helped with the oozing/blobbing, but still get a fair amount...
Otherwise, I like this stuff. It prints easily, and stayed on the bed with the hairspray just fine. Did not need to add a brim to the parts I printed with it (had to have a brim with the ABS as they are small contact area items). Just the oozing is a "problem" and it isn't so terrible that I can't deal with it.
the parts turned out well and seem to be MUCH stronger than their ABS counterparts. They still need a little more tweaking (around screw holes mostly), but I think we may have a winner with this filament. Quite happy with it overall.

Cost was $32.00 + $5.50 shipping for a total of $37.50 for a 1lb spool (roughly 0.5kg) ordered thru Octave via Amazon...
and just because - spool size comparison... the old Octave spool, a standard sized Hatchbox spool, and the mini spool of the Taulman 910...
