Thank you so much Smithy for your consideration 😄
A little clarity on...
1. Can I Bake my Nylon spool on my ultimaker3 heat bed. (like Ultimaker website suggested for PVA). If yes, then what temperature and time for nylon?
2. Yes, I agree the Polybox would be better. But it will take few days to ship to my country and till then i have imp prints to give, So made this hack myself. But my question is the polybox claims to maintain humidity % below 10% and claims hygroscopic materials requires humdity% below 15 %. I am pretty sure my hack box is not keeping humidity% below 15%. it somewhere between 40-45%.and on ultimaker website it says Hygroscopic materials can print upto 50 % humidity,
So what should be the humidity% maintained for prinitng Nylon an Pva ? -
Hello Everyone:)
My NYLON and PVA are showing signs of moisture absorption (crackling sound when printing and bubbles)
My current room humidity measures 45- 50%One thing still not clear is what is the Humidity % required to print PVA and Nylon (hygroscopic materials) without absorbing humidity ?
On ultimaker website it seems to be written upto 50% is okay.
but polymaker seems to say less than 15% humidity is required to print.
I store both my materials in airtight box with lots of silica.
I have attached photos of the same.

https://ultimaker.com/en/resources/52602-material-handling-and-storageWhat is the best option to print with my current humidity % (45-50%): ?
Option1: Bake Nylon and PVA on the ultimaker 3 heatbed at 55 deg for few hours before hand when printing. and later keep it in the airtight box with silica.
Option2: Make a carboard box with a lots of silica in it and put it on the ultimaker spools and stick it leaving 2 holes for material to feed into the feeder. ( I have made this for time being for some urgent prints.
Option3: cover the whole printer with a huge box so that minimum air goes inside and put lot of silica inside.
Option 4: Buy Poly box (drybox) for Nylon and PVA, But it will disable NFC feature and create other extrusion problems because of travel from poly box to feeder.( i read in posts)
Please suggest best solution to this problem.
