You can switch colors "manually" to do multi color print if colors are in different layers. If you use say PETG or TPU, you want to dry them for many hours before printing so having them dried ahead of time is good


Drier In general is important if you have humidity problems


If you are getting a printer say Bambu with AMS Pro, it has drier built in now too.

I was able to get the coupon to apply to a subscribe and save. It reverted to the normal price, but took off another 5%. Luckily my S&S delivery is next week anyway and then I'll cancel. Nice find!

I have one of these. I also printed the top extensions to double the capacity. I'm pleased with this dryer and it has served me well so far.

I haven't used it, but I found a bunch on the Bambu app just searching "Sunlu S4". Here's one that I think doubles the capacity:
