If you first get a 3D printer, you might be confused by the different types of 3D printer filament. To help you get started, this guide will explain the basic filament for 3D printers and how to choose the right type for your projects.
The Different 3D Printing Filament Types: Is PETG or PLA stronger?
What is a filament in 3D printing?
What does the filament do in a 3D printer? They are the material. When you print on paper with a printer, you need ink or toner. In 3D printing, use something called “filament.” It is essentially a long, thin wire made out of plastic that is wrapped around a big wheel or a spool.
The D printer draws the plastic wire into a heated part called the “nozzle.” The plastic inside the nozzle melts until it softens, much like toothpaste. After that, the machine starts to move the nozzle around and deposit the molten plastic in super-thin layers. When each layer cools and solidifies, it adheres to the layer beneath it. The printer is creating thousands of these small squares, bonding them one layer at a time to form a 3D object from the ground up.
There are so many 3D printing filament types, and all of these types have very different characteristics. Some are hard, some are soft, and some can withstand very high temperatures. How many types of filament are there for 3D Printing?
How many types of filament are there for 3D Printing?
There are over 30 distinct types of filament. The two most common types of filament for 3D printing are PLA and PETG. What are the different 3D Printing filament types?
For nearly everyone just getting started, the most popular selection is the PLA filament 3D printer that users swear by. Polylactic Acid, the full form of PLA. It’s easy to see why it’s so popular: it’s simple to use. It does not need to be heated to a very high temperature to melt, and it does not shrink much when cooling down. This means your prints are less likely to warp or peel away from the bottom of the printer. And since it’s made from things like cornstarch rather than petroleum (a fairly common raw ingredient for plastic), when it liquefies, it smells a bit sweet, and it’s more environmentally friendly than most other types of plastic.
PETG is the exact same plastic that’s used to make water bottles. It’s a little trickier to print than PLA because it requires more heat and can be a little “stringy,” but it’s much more durable. It is suitable to be a little tougher or left out in the sun.
Which is the best filament for a 3D printer?
The best 3D printer filament? It depends on what you want to make.
If you want to 3D print figurines, toys, or other decorative items for your desk, a PLA filament 3D printer is the way to go. It is available in many vibrant colors, and it provides you with the cleanest details.
PETG is frequently better if you are printing a replacement hook for your wall or a stand for your phone. It won’t break or snap so easily, and it can take higher temperatures.
By the way, when you buy, note that most 3D print filament varieties come in one standard thickness – 1.75 mm. Always refer to your printer manual to ensure you are purchasing the right size.

FAQ
What are the Different 3D Printing Filament Types: Is PETG or PLA stronger?
PLA is the best choice for beginners because it is easy to use, though it can snap under pressure and melts easily in heat. PETG is a tougher, more flexible alternative that can survive the sun and heavy use without breaking, but it is slightly harder to print and can be “stringy.” Essentially, use PLA for things that need to look good on a shelf, and choose PETG for parts that need to work hard or stay outdoors.
What can I make with a 3D printer?
The options are close to limitless! Here are a few useful ones for those just starting: custom drawer dividers or cable clips, phone stands, keychains, DNA mode, or iconic structure, etc.
