@pete Great news, is this the spec?

If so what is it’s elastic temperature limit compared to Polymaker PC+? I’m thinking of engine bays or under the hood performance. Is it a specific brand you’re buying in, like 3D Elements, or a the same one you were testing/using, that you referred to in other posts.

Any tips on using it?

Also @pete another thought, what are the recommended drying temperature limits of a Robox SmartReel?

I’ve seen 4-5 hours @85ºC in an oven to dry nylon, so has anybody tested the Smartreel’s EEPROMS heat tolerance, when used this way? Just another 2¢

Look interesting

Any updates on the material specs for this reel?

 

[Mike @17bt CHORLEY, Lancashire]

I found the answer to the CEL RoboxSmartReel EEPROM limits, by using google rather than the Forum Search and @chrisyt of CEL had this to say in 2014.

Some of this info might help you out:

Datasheet for EEPROM:

http://www.atmel.com/images/Atmel-8787-SEEPROM-AT24C04C-08C-Datasheet.pdf

(Operation MAX 85°C, Storage/Reflow MAX 150°C)

I must admit, oven heating sounds like a bad idea – the drying instructions you’ll find in the materials datasheet are referring to blowing hot air through polymer pellets in a commercial dryer – we’re not sure of the effects on filament (diameter/roundness tolerance, sticking to itself, reheating degradation etc. etc.), I believe enough silicagel will ‘suck’ moisture from filament….

…so using a hot air oven isn’t to be recommended with a SmartReel at all, especially using the methods and at the temperatures banded around on 3D printing sites. I now know I’ll be using a rechargeable silica gel pack, and an airtight case. 🙂

Does anybody have any better specs on this material please, the specifications tab on the Robox link is pathetic. I’d like to know at what temperature this material starts to creep loose its strength in a warm environment, so what is it’s operating environment top limit in ºC.

Surely it can’t be too hard to have this information at hand, as Taulman give it out on their pdfs, but no idea whose P12 this is either, or whether its comparable.

My first print with this on SmartReel, used filament defaults and Normal.

Shiny side of the bed. Cleaned with IPA. In my experience Nylon sticks far too well to the rough side, I have ripped the surface of a few beds.

Default print temps attached.

What do you want tested? I have a hammer. I also made a 5mm x 1.8mm flat section to test breaking strength but it beat me. Until I find a way to tie between my car and the side of the building it will remain undefeated.

Thanks @pete for the pictures & feedback, and the results look well good enough to give it a try, so I have ordered a reel from the website. (y)
