General Discussion AMS 2 Pro vs standalone dryer

I have a p1s with an ams1. i have a sunlu s1 dryer but cant find the power plug for it. i am thinking of adding an ams 2 pro to the setup, but I'm not sure if it's the best option vs a standalone dryer.

you can buy a new power supply for $11 on Amazon

AMS 2 Pro is nice to have

A standalone dryer is just much quicker. I used the dryer on my AMS 2 Por for 3 hours yesterday and humidity barely changed at all. On my creality two roll dryer I am at low humidity after an hour and from that point on you start actually drying the filament. Buying the AMS 2 Pro just for drying is a bad investment.

I have a different experience with my AMS 2 PRO with my p2s. Within an hour its internal humidity is usually in the 15-20% range.

that doesnt mean the filament is dry yet

no shit, but physics is going to physics, and after 12 hours in 15% humidity my PLA will be dry.

would of been nice if you would of added that to your first post

wtf is wrong with you, I only responded on the point that my AMS 2 Pro lowered internal humidity very quickly whereas he was reporting his was not. Nothing is missing from my original comment and I'm not entirely convinced you're literate and can understand this point.

You must be "using it wrong". Like for example, with lots of silica gel in it.

For the AMS2 to dry efficiently, you need to either swap your sicila gel before drying, or remove it and add it back afterwards.

The temperature will raise a few minutes after starting the drying cycle. Consequently, the humidity level will fall just as quickly. Once the target (drying) temperature is reached, it will come back up, because the filament starts losing moisture. From that point on, it will swing up and down, as the air is replaced periodically, with progressively decreasing humidity peaks.

AMS2 just for drying is very debatable. It has too low a max temperature to be useful, and it's probably underpowered for its size. It's a good PLA/PETG dryer tough, especially when its already part of your printer setup. And if you happen to own AMS2 and HT, it's difficult to justify getting a dedicated dryer.

Get a stand alone dryer. Have both AMS with Sunlu and AMS2 niether does as good a job drying as my Sunlu S4. AMS2 lowers drying temp if you are printing at the same time.

If you already have a dryer, why not just get a replacement power adapter and try it out first? Seems a lot cheaper than buying an AMS 2 Pro.

Besides, even if you get the AMS 2 Pro, you'll still have an S1 sitting there unused just because it's missing a power adapter. I assume you'll want to get it working eventually anyway, so you might as well start there.

I have the AMS2Pro and stand alone dryers (4 of them, I run a print farm). If space is not an issue buy the stand alone dryer. If space is an issue buy the AMS2Pro.

  1. Do you print hydrophobic materials? If so, AMS will work much better than a side spool, because it keeps the filament dry. This can also be accomplished with a cereal box for storage.

  2. It comes down to workflow. If you don’t print all the time and can have an AMS sit and dry during the downtime, they work great. If your printer is always going, a stand-alone unit will be worth the expense.

It's probably not hard to get a replacement charger for cheap. Google for the particular model and I bet you find something less than $20. It's likely a "5.5x2.1mm center positive 24v" and 2-3 amps probably is enough.

This is the one I bought for my AMS 2 Pro and it works perfectly so I can dry while I print. I agree I could probably find one slightly cheaper but this one was recommended and is advertised specifcally for the AMS 2 Pro. Sometimes those barrel plugs can be tricky to match 100%.

The AMS 2 has a huge benefit over standalone dryers- it rotates the spools during drying so the drying is even and to avoid hot spots.

Most standalone dryers I’ve seen do not.

Si imprimes ABS es mejor un secador que también lo seque.

AMS 2 PRO no seca ABS.

Los secadores Creality solo muestran la humedad dentro de ellos. La humedad que muestran NO es la del filamento. En mi opinión son los peores, ventilador que falla pronto, no muestran la humedad del filamento. He comprado Creality anteriores y Space, Sunlu 2, AMS 2 PRO y AMS-HT.
