Topic: Drying pellets

Hi,

What are you using to dry your pellets?

My wife will not care for me hogging the oven time and time again so I sm looking for a drying machine that can handle 1-5kg at a time.

Any advice?

Re: Drying pellets

Folks have used food dehydrators something with a thermostat would be the most helpful.

Somthing like this perhaps.

+1 to food dehydrators. I've used them for drying nylon and PETG with efficiency.

Printit Mason and Printit Horizon printers
Multiple SD2s- Bulldog XL, E3D v5/v6/Lite6, Volcano, Hobb Goblin, Titan, .9 motor, Lawsy carriages, direct Y drive, fishing line...the list goes on
Filawinder and Filastruder #1870.....worth every penny!

I made a vacuum chamber and suck it down for about 30 minutes. Only problem is you have a consumable with this process, the oil.

Very cool. Post pics if you could.

I was a little short winded with my earlier response, so for future users, a food dehydrator isn't the only option. There is a product called Print Dry which can not only dry pellets, but also entire spools even while you print. This is spectacular for products like Nylon and PLA.
Another option is a convection oven. This is typically more expensive than a dehydrator, but more durable and you have settings to control the heat. I'm going to buy one of either product soon since I melted the plastic trays on my dehydrator while drying PETG. sad

Another option  would be a vacuum oven. But these are slower than moving air.

Re: Drying pellets

If you want to go cheap you can make a filament dryer . a simple configuration  of a 5 gallon bucket with holes a heat bulb  AKA 60 watt incandescent and a small fan.

So this is my vacuum chamber. I bought a broken pressure cooker for 2 bucks, put silicone on the lid (twice) and cut an aluminum plate to fit and added fittings. 3D printed a filter adapter and cut some high quality household air filter (around the edge of a used filter) so it wouldn't suck it dirt when I released the pressure. The vacuum only pulls down to about 28 inches so I heat it up to about 110F to ensure the moisture has boiled off. It seals so well, I left it for a week and it didn't drop a single inch of pressure! But like I said, to keep doing this way, eventually the oil in the vacuum pump will become contaminated and have to be changed out, so although it keeps you from heating the pellets much, it's not cheap in the long run. But it was a fun project.
