Rejuvenating filament?

Recommended Posts

I have about 1/2 a reel of UM blue filament from when I purchased my machine last october (2014), I store my filaments, samples and loose 10m etc lengths in sealed plastic bags as supplied and then in a large "Really Usefully Box" .

My UM blue is getting a bit brittle and keeps breaking as it comes off the reel.

Does anybody have a simple solution to rejuvenate the filament? I quite like the UM blue so would still like to finish the reel and not waste it so any surgestions welcome,

Cheers Izzy.

Cheers  guys, I tried my reel in the oven for 2 hours at 70C garnished with a little parsley...

When I looked before butting it in I noticed a fair bit of cracking so I'll let it settle and see if it's only a small area effected or it's a write off.

:) would be funny to have scented filament.

 

Protopasta has coffee flavoured filament. :Pit prints great, looks like slightly translucent coffee/chocolate colour and smells of coffee when you print it!

 

hahaha cool

I hope kids don't try to eat the prints.

I lose my sence of smell and taste nearly 3 years ago due to the Flu, I have a small amount back about 8% but very limited and I can't necessarily identify some of the scents.

I don't know what any of the printing smells like so I have to rely on my wife to say if anything smells bad or is too much.

I had a "new" to me roll of Colorfabb translucent green. The guy I bought my printer from threw it in the deal. It had a manufacture date of 2011, but was still vacuum sealed. It was cracking and brittle.

I heated up a big pot of water to 70°C, took it off the heat. Placed the whole spool on a potato masher, and lowered it in the water for 30 seconds. Left it to cool and dry and it's printing fantastic.

Could not resit to give it a try :)

Had some faberdasherry grey, less than a year old but very brittle.

Used anakin's 70 degrees / 30 sec advice, think it did work, it's not brittle anymore.

@anakin did you do anything special regarding drying the pastic? I've now left it air drying for a few hours but when I shake the spool it's still wet .... I'll leave it over night before making an attempt to print with the stuff.

Im tempted to put something together using a Lego Mindstorm, a motorised system that would drive a reel as the take up reel pulling the filament off of the treated reel perhaps past a hair drier set on low heat to remove the moisture without over heating the filament.

I was thinking to also reel it onto a bigger spool to get rid of the massive tension in the last part of the spool... I like the mindsstorms idea... I have one (my son has one) that's not being used for a while... But i don't have the time now, just ordered myself a shapeoko3 so I need to keep reading there forum to be prepared when the kit arrives :)

Nope, nothing special. I only really let it dry for 20 minutes or so. I did kinda work the roll as some of the lines were gently stuck to each other.

We're totally offtopic here....

The x-carve and shapeoko have the same background, basically (mechanically) the x-carve is more a shapeoko2. The shapeoko3 is mechanically much heavier/sturdier.

My machine is on on it's way for delivery next week, just paid fedex the tax... I'll start a thread in the coffee corner when I managed to put it all together...
