Dry filament is critical! I just purchased a dehydrator for my 3d printer setup (a generic one off of Amazon - save yourself a lot of money rather than something labelled for printer use). WOW! I don't think I can overstate how much of a vast improvement in quality I'm seeing. Adhesion is through the roof on everything I've tested - nylon, abs, polycarbonate. This is across the board true on printbite, buildtak, and glass. Nylon is string free! Layer adhesion is much stronger, and I can print thinner walls without cracking. I've run several prints without chamber heat. I wouldn't say it is any more critical than having a well calibrated system with an absolutely flat and clean build surface. Once you get all of that right, there is still an order of magnitude improvement when you use a dehydrator. If you think your house is in a dry climate - that's not good enough. I dispense from the dryer and leave it running for the print duration.

Out of convenince and curiosity, I opened one bag and placed it about six inches away from a radiant space heater I have down there right now and sure enough after 24 hours the dessicant's color changed indicating 0 moisture. I've now opened up all of my filament bags and they are now camping in a circle around my space heater drying out. Eventually I'm going to go the route of dedicating a storage tote full of dessicant as my filament storage but if you ever need to dry filament in a pinch and don't want to put it in the oven (AKA don't anger the wife) this works.]]> obelisk79 General Fri, 18 Jan 2019 09:59:20 -0500 https://reprap.org/forum/read.php?1,844432,844857#msg-844857 Re: Dry filament is critical! https://reprap.org/forum/read.php?1,844432,844857#msg-844857 I’m currently building a new delta and plan to build a heated filament enclosure on top. What I don’t know is the ideal temperature to run it at.
What temperature do you find the best?
Thank you,

I also purchased a carousel from a local kitchen appliance store for $7 dollars that fits inside nicely and allows the 1kg spools to spin freely on their sides. I can get two of them in the dryer, and the filament feeds out through the door without modification. I did use some tape to hold the door shut.

There are much cheaper dryers available. I rolled the dice and upgraded so I could get the controls and wattage I wanted. It works great!
