3D Printing Filament Types Explained (Without the Jargon)
Most 3D printing websites throw a bunch of technical specs at you and expect you to understand. That's not helpful.
Here's the simple version: there are really only three main filament types you need to know about as a beginner.
PLA: The Beginner's Choice
What it is: A plastic made from plant materials like corn. It's the easiest to print with.
Why use it:
- Prints cleanly with minimal warping
- Works on almost any 3D printer
- Sustainable and eco-friendly
- Great for decorative objects and learning
Why not use it: It's not as strong or flexible as other options. If you need something tough or that bends, look elsewhere.
Best for: Toys, miniatures, models, decorative objects, and your first prints.
PETG: The Middle Ground
What it is: A stronger type of plastic that's more flexible than PLA but tougher than many materials.
Why use it:
- More durable than PLA
- Flexible enough to handle some stress
- Still relatively beginner-friendly
- Good for functional parts
Why not use it: It requires a bit more skill to get right. You need a heated bed and careful temperature management.
Best for: Tool holders, brackets, functional parts, anything you'll actually use and expect to last.
ABS: The Professional Grade
What it is: The strongest and most heat-resistant plastic. It's what plastic car parts are made from.
Why use it:
- Extremely durable
- Heat resistant
- Can be sanded and finished nicely
- Best for engineering projects
Why not use it: It's difficult to print, requires an enclosed printer, and can warp easily. Not recommended for beginners.
Best for: Replacement parts, functional prototypes, anything that needs to survive actual use and temperature.
How to Choose
Here's the decision tree:
- Is this your first print or a toy? → Use PLA
- Do you need something that lasts and gets used? → Use PETG
- Do you need something industrial-grade? → Use ABS
That's it. Three options. Pick one based on your project, and you're good to go.
The Eco 3D Print Advantage
All three of our filament types are sustainable. You're not sacrificing the environment for strength or durability. You can pick based on your project needs, knowing you made the right choice for the planet.
Happy printing!
