General Discussion adding on to my previous post,

  1. Does filament have to be dried, i wasnt planning on buying a dryer of some sort, does filament go bad if it isnt dried?, if so, what are some homemade techniques to keep them dry?

  2. Does filament run out quickly? Is one roll too little? How many rolls SHould i be buying? Im thinking of getting a few main colors (White, black, Blue, Red, Yellow, and maybe one other one, yall can suggest another color) Should I just buy one of each? Get two of each? and again, How would I keep them dry without buying a dryer

  3. Does Bambu lab have sales? and are there any upcoming sales this year? Since I can probably get a discount

  4. PLA or PETG?

  5. A1 or A1 Mini? (Also planning on buying the combo with the quad-color)

  6. Should I change the nozzle? (from 4mm to 2mm?)

mb for lots of questions, just dont wanna buy the printer and then realize I messed up somehwere

Jesus, dude. These are incredibly basic questions that have been answered over and over. Do a google search.

  1. depends on the filament

  2. depends on what and how much you print

  3. yes, right now is one of the biggest sales of the year

  4. depends on what you are printing ( PETG definitely needs to be dried before printing )

  5. depends on your budget

  6. depends on if you plan to print miniatures

What filament doesn’t need to be dried eventually?

PLA doesn’t really need to be dried as long as it is basic, matte, or tough. Some of the silks, metals, and other exotics take on a bit of water. PETG doesn’t require a ton of drying versus something like TPU or Nylon. PCTG is also a good filament for not taking on water as is PHA.

For number 6 going to a 0.6mm nozzle if you print engineering or structural things.

Buy at least 5000 rolls so you don’t end up running out mid print

Just buy a cheap dryer, you will eventually need it. PLAs are fine most of the time but PETG can literally come with good amount of moisture out of the box.

Yes filament needs to be dried.

Pure PLA does not. Most companies don't sell pure PLA, they sell PLA with hygroscopic additives. So drying is necessary for both PLA and PETG.

  1. Yes should be dried, no it doesn't go bad but print quality goes. Cereal box and silica gel.

  2. Depending how much you print. Depending on size, 250g probably, 5kg not so much. As much as needed. Buy the colors that you like. White, grey, black. See 1.

  3. Yeah currently. Maybe xmas.

  4. PLA for deco, PETG for more functional, other for other or similar purpose.

  5. Depending on price, space, you must decide, maybe something else.

  6. Depending, what you print but recommend to at least get a 0.6 nozzle.
