longevity of Fillamentum nonoilen

Hi there,

I've just tried to print with the above mentioned filament after it sat in its bag for about a year. The result was somewhat underwhelming. The calibration square at a live-z that just printed fine with PLA had pretty much no adherence between the individual strands. It is still strong in the direction of the extrusion. And the surface feels slightly sticky/tacky to me, not the way the few prints I did when I first opened the pack.

 

The spool currently sits in the dehydrator at the 70 degrees Fillamentum sates on their website. They also say that moisture will change the mechanical properties.

 

Has anybody any experience with the stuff? Is there anything I should look at apart from drying and trying again?

 

Thanks in advance for all the clever answers.

Hansjoerg

70 degrees celsius for drying PLA ?. That seems way over the top. I'd think that at this temperature the strands would bond to each other. Manufacturers of filament driers recommend 45C for these filaments. Maybe it's a very special sort of PLA ?

It's exactly the temp that Fillamentum recommends.

 

NonOilen is actually not a PLA but a cellulose lactide based material. It has interesting properties, according to Fillamemtum it can withstand quite high temeratures, although it's printing temp is only 175-195 degrees.

RE:

Thanks for the clarification,

I looked the properties of nonoilen in Fillamentum's web. In theory, it looks interesting: food safe, dish washer safe and prints at low temperatures. 

Nevertheless, Fillamentum recommends to use lower layer heights for steep overhangs. They also advice against printing above 180C, to avoid excesive stringing and rough surfaces. All this makes me think that the mechanical properties and exterior finish of nonoilen prints won't be as good as PLA.

I haven't use it extensively yet. I just added a roll to an order I placed with them for other filament a while ago and used it for some lithophanes because I like the ivory like colour.

The last print I did were a bunch of carpal bones with lots of travel moves and support. It came out quite well and no noticeable stringing. Drying had fixed the sticky surface feel.

I haven't tried anything else but might as well give the cup they advertise with it a go.
