Subject: What do you want in a filament material?

Hi guys,
Until last year I worked in environmentally friendly food service
packaging,  and have the relationships to get custom blended PLA (or other
not-stock-available-resin) filament produced at substantially lower prices
than currently available.

I've only been involved with this community about three months (watching
reprap for years), so I would love to hear any thoughts or suggestions you
might have on what could be better in the world of ideal filament?

Adam B. Levine

personally the biggest thing for me is consistency, then price,

but i to tend to have to go with what i can afford. i do try to get
the best i can afford though.

> * i do try to get **the best i can afford though. *

What factors are important in determining "the best" - Durability? Clarity?
Low melt point? High Adhesive? Easily textured? Flexibility?  Is it all
just application specific based on what you're printing at that moment?

There are quite  a few options out there, so the more we can narrow down
what characteristics are missing or too expensive in the market, the faster
we can get 'er done.

The most important thing is that it has a consistent diameter and is consistently round. If you're thinking of selling filament, you need to memorize this article: http://www.protoparadigm.com/2011/11/filament-tolerances-and-print-qu...

I've been told that most PLA is not food grade, and also that it may leach
pigment when exposed to alcohol. If a filament could be made that doesn't
suffer from these drawbacks, that would be great.

I remember there was a vendor who sold "soft PLA" for a while, and maybe
they are still selling it. If you could accomplish that, or even a
squishy/rubbery material, that would be amazing. I have no idea how
possible that is though.

weed trimmer line (nylon) comes out quite flexible, but also emits toxic
gases when heated to printing temperatures

It's funny you should mention that - I actually have a spool here of weed
trimmer line made from a new bioplastic and am just waiting for my
printrbot to arrive to try it out.

I would like that each roll on the label reflected the recommended
extrusion temperature. Another thing would be to the maximum and
minimum diameters.

There is no such thing as extrusion temperature. What should be well documented is the transition temperature range of specific plastics. As some rolls of ABS have been known to extrude better at lower temperature and some at as high as 250C, tested temperatures by the manufacturer would help out users in identifying the optimal temperature to extrude at.

How about making plastic that snaps back when the extruder reverses to
prevent ooze? Kind of like Silly Putty, it would flow when you slowly
push it through the nozzle, but snap when the extruder gives it a
quick tug in reverse.

The only problem I have with current filament suppliers is that sometimes it's not wound properly and the filament binds up when printing. Of course, cheaper is always good. Assuming quality holds up - the cheaper suppliers have inconsistent diameters, which causes problems. I guess the other thing would be fun would be variety of PLA. I see good variety of ABS, but less variety of PLA.

What I want is consistent quality.
No enclosed air at all, same melting point along all the length,
perfect round shape of the ordered diameter and with a constant
diameter along all it's length.

There are enough other problems. I don't want to worry
about inconsistencies in my filament.

Thanks to everyone for the feedback, and if you have any more please keep
it coming!  Are the 1lb or 1kg spools a good amount to have on a roll?
 More or less?     I've gotten some traction with "a more affordable, high
quality multi-colored PLA filament in both 1.75mm and 3mm", but my long
term interest is looking at all the new biopolymers out there, and see what
kinds of things we can print with the desirable ones.   The fact that ABS
and PLA are the only options is partly suitability, but mostly
availability.

Lots of options out there that haven't even been considered, I love new
markets.

Okay this may be the stupidest question ever: why does it have to be round?
why can't a printer take square or octagonal material? flat edges are
easier to consistently produce in other materials so I'm going to assume
that is the case with abs.

...a brilliant idea is a stupid one that turns out not to be...

having said that, my guess would be heterogeneity - the corners would
melt faster than the faces, might absorb water differently, and would
probably be more prone to accumulate nicks and dents that would cause jams

easier to cut a round hole in the barrel than a square or octagonal one :)

the barrel walls need to be close enough to the filament that going through
the nozzle is more attractive than squeezing up  between the filament and
the barrel wall towards the top of the hot-end

I just want to see the actual plastic resin being used noted on a label
somewhere - if it's Chi Mei PA-747, please list it as such and don't just
say "ABS".  Glass transition temperature and melt flow rate would also be
helpful (but as long as you state the specific resin, those values can be
readily looked up).
