Polylactic Acid (PLA) is a biodegradable thermoplastic, made from renewable resources like corn starch or sugarcane. It typically requires a nozzle temp from 190C-215C and a bed temp from 40C-60C

It is important to follow the manufacturers guidelines as material can vary from one manufacturer to another.

ABS Plastic Filament: Stands for acrylonitrile butadiene styrene. Known for being resistant to shattering when dropped or hit.

PETG is a durable copolyester. The PET stands for polyethylene terephthalate and the G means it’s been glycol modified for extra durability.

It's a tough material, that’s extremely durable and prints without odor. Typically Polyethylene filament is supplied in a range of translucent colors, and prints with a glossy finish. It makes it ideal for printing anything that needs to be shatterproof or translucent.

Of course the wood filament is not just wood it's actually PLA that has wood infused into it. It prints out and gives the illusion of a wooden part. This filament can be difficult to work with, it is important to follow the recommendations.

Look at the properties for each material. Decide what properties you want your finished item to have, i.e. finish, color, strength, impact resistance. Then look at the printing difficulty. Remember that most people start with PLA and work from there. The more exotic materials may cause issues and you will have to be prepared to experiment and/or dial in the settings.
