Generic PLA should be ok!

RE: XYZ PLA Filament on Prusa MK4 - clog and settings help

Is XYZ Filament good filament?  I am a little hesitant to use it again since it clogged the nozzle and I had to disassemble the hotend, remove the nozzle, heat it up several times and push a rod through to remove the clog.  It wouldn't clear on its own.

Do I need to dry it out?  What's the best way to dry it - I don't have a dryer.

I have used an electric oven set to 50C to dry filament... 

A GAS Oven is not suitable.

How long do you put it in the oven?  I guess the spool and filament is fine at that temp?

RE: XYZ PLA Filament on Prusa MK4 - clog and settings help

I put mine in for 2 hours, twice, because the timer doesn't go more than two hours. and My reels survived... 

I Now have a fruit dehydrator that goes up to 10 hours. if need be.

To dry 3D printer filament, you need to consider both the temperature and the drying time based on the material type. Here are some recommended settings for different types of filament:

PLA: Dry at temperatures between 40-55°C for 4-6 hours. This material is less hygroscopic, so it requires a lower temperature and shorter drying time.

PETG: Dry at temperatures between 55-65°C for 4-6 hours. This filament is more hygroscopic than PLA, so it needs a slightly higher temperature and the same drying time.

ABS: Dry at temperatures between 70-80°C for 4-6 hours. ABS is more hygroscopic than PLA and PETG, so it requires a higher temperature and the same drying time.

Nylon: Dry at temperatures between 75-85°C for 4-6 hours. Nylon is highly hygroscopic, so it needs a higher temperature and the same drying time as other materials.

ASA: Dry at temperatures between 80-85°C for 4-6 hours. ASA is similar to ABS in terms of hygroscopicity, so it requires a high temperature and the same drying time.

PC: Dry at temperatures between 85°C for 5 hours. PC is more hygroscopic than PLA and PETG but less than Nylon and ASA, so it needs a high temperature and slightly less drying time.

PCCF and PA11CF: Dry at temperatures between 90-95°C for 4-6 hours. These materials are highly hygroscopic and require the highest temperatures and the same drying time as Nylon and ASA.

It's important to note that drying times and temperatures can vary based on the initial moisture content of the filament and the specific brand and type of filament. Always ensure that the drying temperature does not exceed the material's glass transition temperature to avoid damaging the filament.

Hi Joan, 

Thanks for the response.  I searched for a dehydrator but the reasonably priced ones are small.  Do you have a recommendation for a dehydrator?

Thanks,

Craig
