PLA, PET-G, ASA – what’s the difference and which one to choose?
3D Printing offers a wide range of filament choices, each tailored to specific needs. Among the most popular are PLA (Polylactic Acid), PET-G (Polyethylene Terephthalate Glycol), and ASA (Acrylonitrile Styrene Acrylate). While all three are thermoplastics that melt and solidify during printing, their performance, durability, and ease of printing differ greatly.
Choosing the right one depends on what you value most: ease of use, mechanical strength, or outdoor durability. This article explores each filament in depth, compares their properties, and provides guidance on when to use them.
