Too Lazy; Didn’t Read Version : While neither one of these two were perfect by any stretch of the imagination, just don’t buy the S2 even if it is discounted and you have to pay full price for the Creality Space PI. The difference in performance vs value is huge. Disclaimer: Both of these devices d…

[image] bill.m.davis: but maybe it wasn’t letting the moisture escape properly either? That would be my thought as well. There are 2 key aspects to dehydrating filament. The transfer of heat for the evaporation of water from the filament and the transport of the water vapors formed away from …

[image] JonRaymond: Dry till the spool weight stabilizes as that seems to be the best indication of dry filament. I’d say that short of doing a chemical analysis, that is the only method available to us. Having said that, it is important to note that one must also take into account that cardb…

[image] JonRaymond: Dry till the spool weight stabilizes as that seems to be the best indication of dry filament. … unless maybe it’s a lousy filament dryer, in which case maybe it still isn’t dry even if it can’t dry it out any more. I happen to suspect this may be true, to one degree or an…

I have the feeling, that old school food dehydrators are the better choice for filament drying. I’m eyeing the Graef DA2042. It has 400W and reaches 80°C. Thermal isolation probably still lets it consume less energy than the plastic dryers. It has proper convection and lets humidity escape. Timer …

[image] NeverDie: Even if it improves, how do we know it’s not only partial? Since my last response it occurred to me that there is another way to confirm that moisture has been removed which I had forgotten I am using. One can simply use the hygrometer method. Once the humidity inside of the…

[image] NeverDie: I’ve heard it said that you just need to dry it longer, but how do we really know that’s true? Chemically that doesn’t make sense but in practical use it can approach being true. The sites where water sticks to the filament will vary in all sorts of ways and the water molecu…

@MZip OK, I’ll buy that. Attempting to summarize: it’s both low RH and heat (as well as dwell time) which drive the drying process, not just heat causing low RH with only just low RH and dwell time driving it. Seems as though with this configuration, heat is fairly easy to generate, so do the maxi…

I think you got it. Heat by itself reduces RH and that helps shift equilibrium to water leaving the filament. But heat also provides the energy needed to break water free of the surface where it can be removed so heat helps a couple of ways. Think hair dryers and how slow hair dries without heat. A…

[image] MZip: so if you wait longer at a lower temperature you can get more water out than if you stop drying a roll early at a higher temperature. So practically, without drying to some standard like weight stops decreasing or for a fixed time, lower temperature drying can be as “effective” as…
