Topic: review of Rigid.ink ABS filament 1.75mm
well, I was not expecting to find much difference in filament
materials when 1st offered the opportunity to test and review
some sample rolls of filament from Rigid.ink from the UK by
Ed a few weeks ago. I have used a few other manufacturers
filaments like other 3D printer users. not the over priced stuff
or proprietary spools like Makerbot etc though. but Octave
and a couple similar average cost brands and colors. mostly
ABS 1.75mm which is my preferred filaments. I also used the
low end under $20 spools like from Toner carried in
Microcenter stores locally. and a Solidoodle sold brand. most
are very similar in every aspect and 'do the job' mainly have
to watch for clean, dry manufacturing controls to keep within
size specs so not to clog hot ends. (Solidoodle's had some
spots with sawdust specks due to poor filtering when
extruding the spools, and thats a $45 spool). had better cheap
brands.
as the photos show Ridgid.ink is a bit different in many ways,
most are in MHO an improvement over the norm from start to
finish.
I will start with a disclaimer on my SD2 printer I use still
needing a couple minor tweaks for better infilling and the
Temps may differ from other printers due to Solidoodle
designs.
when I got the sample rolls they came packaged as seen in
photo with stiffener to prevent bending and double zip lock
bags with descant packs for moisture control (a big plus over
some brands).
1st test with Gray,
as for printing, I noticed better adhesion of the extruded
filament not only to my heated glass bed with the typical glue
stick applied, but also layers. plus very smooth layers with a
glossy appearance compared to other brands. not silver but
still grey just smooth and glossy like glass. also noticed when
pulling off ooze from nozzle and again at end of print when
head homed, there was near invisible spider web like silk
(can be seen in finished print pics streaming up off of upper
right front corner of the N scale 1:160th Landing craft door) it
just waved in the light updraft from the heated bed. never had
this with any other ABS or PLA filament. dont know what
chemical compound is used but its not the same as most.
overall summary considering all aspects of desired properties
of ABS filaments for 3D printing from quality control, cost,
print-ability, strength and aesthetics on a 5 star scale with 5
being highest recommendation for purchase. I give it a 5.
also Ed tells me they intend to expand color choices, add new
materials per customer requests etc.
only drawback for me living in the USA is shipping cost from
the UK.
I will update this topic as I test the other samples and note
any differences.
