Best PLA Filaments for Reliable Printing
Whether you’re a 3D printing novice or a seasoned maker, one of the key components to a successful print is the choice of filament. PLA (Polylactic Acid) has emerged as the go-to material for many users because of its ease of use, low warping, and environmentally friendly profile. But with countless options on the market, how do you decide which PLA filament is the best for reliable, high-quality prints?
TLDR
Not all PLA filaments are created equal. Some offer superior dimensional accuracy, others provide vibrant colors, and a few stand out for being eco-friendly or made from recycled materials. Brands like Prusament, Hatchbox, and eSun consistently top the list for reliability and print quality. Your choice should depend on the goals of your project, whether that’s durability, aesthetics, or ease of use.
What Makes a PLA Filament Reliable?
Before diving into specific brands, it’s important to understand what characteristics contribute to a reliable PLA filament. A high-quality PLA filament should exhibit:
- Dimensional Accuracy: Consistent diameter (usually within ±0.02mm) ensures smooth feeding and prevents clogs.
- Low Moisture Absorption: PLA tends to absorb water from the air, which can affect print quality. Some brands package their spools in resealable bags with desiccants to combat this.
- Good Layer Adhesion: This is crucial for strong structural integrity and sharp details.
- Purity of Material: Additives or recycled plastics can reduce print reliability unless specifically formulated for consistent performance.
- Temperature Consistency: A good filament will have a narrow printing temperature range and respond predictably to slicer settings.
Now, let’s delve into some of the best PLA filaments available for reliable 3D printing in 2024.
1. Prusament PLA
Best for: Professionals and Enthusiasts Who Demand Precision
Produced by Prusa Research, the same company responsible for the popular Original Prusa 3D printers, Prusament PLA is recognized for its exceptional dimensional accuracy and transparency in manufacturing.
- Tolerance: ±0.02mm, one of the tightest in the industry.
- QR Code on each spool links to a page showing real-time manufacturing data.
- Vibrant and beautiful color range, with special blends like Galaxy Black and Mystic Brown.
While it’s priced slightly higher than budget brands, the reliability and quality make it worth the investment.
2. Hatchbox PLA
Best for: Budget-Conscious Users Who Don’t Want to Sacrifice Quality
Hatchbox has long been a favorite in the 3D printing community. It strikes a balanced combination of affordability, consistent quality, and wide availability.
- Dimensional accuracy of ±0.03mm.
- Offers a wide color selection, including silk and glow-in-the-dark options.
- Easy to print with, minimal stringing or warping.
Its reliability at a competitive price point makes Hatchbox an excellent choice, especially for beginners and hobbyists.
3. Polymaker PolyLite PLA
Best for: Smooth Surface Finishes and Long Printing Sessions
Polymaker’s PolyLite PLA is engineered with Jam-Free technology, ensuring fewer failed extrusion issues even during long prints.
- Reinforced with improved heat stability to avoid softening in the extruder throat.
- Available in a professional-looking matte finish.
- Consistent filament diameter and reliable feed.
This filament is great for jobs that require multiple-hour prints or fine details like prototypes and scale models.
4. eSun PLA+ (PLA Plus)
Best for: Tougher Prints That Still Look Great
eSun’s PLA+ is a popular choice for anyone needing a stronger, more durable PLA. It’s blended with additives to improve mechanical properties while maintaining PLA’s ease of use.
- Higher impact resistance compared to standard PLA.
- Not prone to brittle breaks.
- Performs closer to ABS without the toxicity or complexity.
Ideal for load-bearing models, cosplay props, and wearable accessories where durability is prioritized.
5. MatterHackers Build Series PLA
Best for: Educational Use and Bulk Printing Projects
This PLA filament from MatterHackers is a solid performer in classrooms, print farms, and maker spaces. It offers good dimensional stability and comes in bulk options.
- Dimensional tolerance of ±0.05mm.
- Comes in large spools for uninterrupted print jobs.
- Minimal warping and very easy bed adhesion.
It’s not fancy, but its reliability and availability make it a workhorse for everyday use.
6. Proto-pasta HTPLA
Best for: High Temperature Applications and Post-Processing Work
Created for serious hobbyists and experimental users, Proto-pasta HTPLA is a “high temp” PLA that can be annealed (heat-treated) to improve its thermal resistance and mechanical strength.
- Annealing makes prints resistant up to 140°C.
- Available in metallics, glow, and glitter variations.
- Made with recycled waste streams – eco-conscious choice.
Use it when you want the print detail of PLA but the durability and heat resistance of more advanced materials.
Other Criteria to Consider When Choosing PLA
In addition to brand reputation, here are a few parameters to evaluate before purchasing:
- Spool Weight: Decide whether you need 500g for small projects or 1kg+ for larger prints.
- Color Availability: Some brands offer unique shades such as gradient, silk, or matte finishes.
- Packaging: Vacuum-sealed spools with desiccants prolong filament life.
- Eco-Friendly Manufacturing: Some brands use recycled materials or carbon-neutral processes.
Tips for Best Results with PLA
Even the best filament can underperform without the right printing conditions. Here are some tips to ensure optimal results:
- Printing Temperature: Usually between 190°C and 220°C. Check the manufacturer’s guidelines.
- Bed Temperature: 0°C to 60°C. Use painter’s tape or PEI sheets for better adhesion.
- Cooling: Enable part cooling for cleaner details and stable overhangs.
- Storage: Store PLA in a dry environment to prevent moisture absorption and brittleness.
- Speed: Start with a lower print speed (40-60 mm/s) for better quality and tune from there.
Conclusion
The right PLA filament can make the difference between a failed project and a masterpiece. Whether you need professional-level accuracy with Prusament, the durable finish of eSun PLA+, or the bulk utility of Hatchbox and MatterHackers, there’s a filament out there that fits your purpose.
Do a little experimenting and keep a well-labeled stash so you know what works best for each application. With the wide selection on the market today, finding a reliable PLA filament has never been easier—or more exciting.
