How We Pick the Best Filament
When selecting the best 3D printer filament, we looked at several features: price, material quality, eco-conscious features, print quality, and ease of use.
To produce our list, we relied on user feedback through direct interviews, forum posts, comments, and reviews, as well as our own testing and years of experience.
We tested every product on the list but didn’t strictly stick with our tests for quality control because various external features, including air temperature, humidity, 3D printer calibration, and print settings, can impact print quality.
Our top three choices are in order of top pick, budget pick, and upgrade pick. The rest of the list is in no particular order.
Buying Guide
When looking for the best PLA filaments for our 3D printing projects, it’s important to consider several factors to ensure the final prints are of high quality. Here are some features to keep an eye on:
Material Quality
Material quality was our primary focus. In addition to testing every product on the list, we rely on community feedback to ensure we get the best information before selecting filaments for our list.
High-quality PLA filament is crucial for successful prints.
We look for filament with a consistent diameter, as this will provide a more even flow through the extruder.
The diameter should be within a tolerance of +/- 0.05 mm or lower.
Additionally, the best PLA filaments for 3D printing should not have many issues with stringing, zits, or blobs.
High-quality PLA filament should have great bed adhesion and layer-to-layer adhesion. After printing, it should be easy to remove the model from the heated print bed.
Color options and vibrancy
PLA filaments come in a wide variety of colors. Consider colors that are vibrant and rich, as these will make our prints stand out.
Additionally, think about whether we want a glossy finish or a more matte appearance when selecting our filament.
Filament Winding
A well-wound filament spool is important for trouble-free printing. If the filament is tangled or wound too tightly, it can lead to extruder jams, breaks, or skipped layers.
The best PLA filaments on the market have high-quality control standards to ensure the filament rolls are wound without tangles.
Opt for filaments that are evenly wound and well-packed.
Environmentally friendly
We gave extra credit to PLA brands with environmental features.
Many brands have made the switch to cardboard filament rolls or offer eco-friendly PLA with recyclable or biodegradable material.
