People that think there is no advantage in a Filament Dryer are missing so much - not only it prints better when dried, but I loved to confirm one more time that even for filament brittleness in the spool itself, drying helps! Anyway, I am so happy to see that we can continue using VERY OLD spools with a clean conscience 🥰

Depends on the humidity of where you store them or how dry they are from the factory. I've tried a dozen PLA brands and there's been no difference printing out of the box vs drying.

@@zackj997 Yeah, how dry it is from the factory is always a concern for me, so I always do a brittleness test to see if drying is needed or now. One in particular is esun's PLA+ (peak green); it's very brittle out of the package so I always dry it before use. I also always dry any PETG I get before printing with it.

Many (most) dryers are bad! If you heat up the chamber and take out a bit of moisture from the filament but do not exhaust that wet air frequently the effect od drying stalls. I built my own with controlled fresh air in and old air out - and yes, it takes more energy for to so, but drying means energy consumtion otherwise its only a way to warm up a spool with a small piece of drying effect. Keep the spool in a warm and wet air for hours is wasted time.

I am so curious about this video - I know Igor started working on it a few months ago. One of the spools he wanted to test was from a Brand that I also used to buy A LOT here in Spain. He had a few very old spools - but the challenge was to buy them "brand new" to compare - let's see!!!!

This came in handy. I had my old 3D printer in storage since early 2019 and just unpacked it all - with 10 or so rolls of various filament. And the very first thing I noticed was how brittle the PLA was. I left the rolls I wanted to dry for days in my dry box (for camera gear) and have printed some small storage boxes for a peg board. No scientific tests, but yes, less brittle now and the prints seem decent enough. Very relieve that I can probably use all this old material:) As a side note, I haven't printed FDM since 2019 so missed the whole Klipper revolution but think I will go for it now and give my old printer some nice upgrades. While it's good to have it back, I'll get tired of it's 45mm/sec print speed very fast.

Well these results kind of support my opinion that many people are worrying too much about storage. Sure, I have petg and tpu filaments in a plastic container with some silica, but I store PLA in the open (no direct sunlight), only dry it when i have not used it for a longer period and never had any issues.

I want to put in plug in for patreon. Not only is it good to support someone who is doing good work for the community, having access to the accumulated data is very useful. I reference the spreadsheet every single time I buy filament. I haven't found any other way to effectively differentiate this PLA vs that PLA, or whether what I'm doing is a better fit for ASA or nylon. Buying 3d printing filament without Igor's data is buying blind, or at best relying on anecdotal or biased reports.

Love your videos as always, but just one correction. The older "Prusa" branded filament was made by Filament PM (Plasty Mladeč) as you noted, but it's not the same as Prusament. That product line is still sold by Prusa in their store, though, as the "Made for Prusa" line, but "Prusament" is a separate brand that is manufactured by Prusa in-house. I'm not entirely sure, but I think Prusament has always come on the hex spools, and used QR codes. The Filament PM spools have Data Matrix codes, and I did decode them from your footage to confirm that they are not Prusament, unless Prusament filament was spooled onto those spools at some point and the code is incorrect. The old "Prusa"/Filament PM PLA you have is their "Silver" PLA, and the PETG was their "Prusa Orange" PETG. They did sell a Filament PM-manufactured "Prusa Orange" PETG back then, but I assume Prusa reserved that term for their Prusament brand at some point, as now you can only get Prusament with that name. However, you can still get that filament from Filament PM, which they renamed as "Orange 2018" PETG.

Thank you for this video. Keep up the good work! I have tried to reuse some old filament as well, and came to similar conclusions. 1. Running brittle filament through a CoreXY is not a good idea :-) 2. Sometimes drying filament makes it less brittle. I experienced that as well, and some of it would work in my Bambu, as long as I wouldn't leave it in overnight. It would never work reliably in the AMS. 3. Some filament stayed brittle, even after drying. I had some old black and white Dremel filament (8 years old or so?) which would NOT improve even after drying.

I would be interested to know how the strength of 3D printed PLA parts changes over time given how the filament becomes brittle when left alone. Even in a large storage box with pounds of desiccant, the humidity remains low, but eventually I pick up an older spool and the filament has broken around the rim-hole.
