Comparison: Which Best 3d Print Filament is Right for You?
When evaluating the top three contenders, I prioritize dimensional accuracy, print consistency, and material properties. The three filaments that consistently topped my charts were the SUNLU PLA Black, the eSUN PLA+, and the OVERTURE PLA White, but they serve different user needs.
The eSUN PLA+ is the clear winner for performance and durability; it offers superior tensile strength and impact resistance, making it ideal for functional engineering parts or high-speed printing where standard PLA tends to fail. If you print parts that will be handled roughly or need maximum resilience, eSUN is worth the premium. Conversely, the SUNLU PLA Black excels in pure consistency and ease of use, delivering exceptional dimensional accuracy at a slightly lower price point. I found that SUNLU’s winding quality was perhaps the best I tested, meaning fewer headaches for users running prints unattended.
The OVERTURE PLA White functions as the best high-quality budget option, offering nearly the same dimensional precision as SUNLU but often available at a slightly more accessible price point. I recommend OVERTURE for general hobbyists and beginners who want premium results without the “premium” price tag. While the eSUN provides the most durable outcome, the OVERTURE or SUNLU options are superior if sheer aesthetic quality and consistent layer lines are the goal in non-functional models.
My Selection Criteria for Choosing the Best 3d Print Filament
When I first started testing these materials, I established stringent rules to objectively judge performance, focusing heavily on what truly impacts the final print quality and user experience. I found that simply looking at the stated dimensional accuracy is insufficient; the consistency of that accuracy across the entire spool is what matters most. A variance of +/- 0.02mm means nothing if the spool is poorly wound, introducing friction and inconsistency halfway through a 1kg roll.
I also place immense value on material handling characteristics like moisture resistance and spool design. I’ve learned from countless failed prints that poor vacuum sealing or spools that create excessive friction can destroy a print, regardless of the filament material itself. For me, a top-tier filament must demonstrate excellent layer adhesion across a broad temperature range and minimize common artifacts like stringing and oozing without extensive tuning.
What I Prioritize in 3D Filament Specifications
In my testing, I prioritize three core technical specifications: consistent diameter tolerance, glass transition temperature (Tg), and material purity. Consistent diameter, ideally +/- 0.02mm, directly impacts extrusion rate and prevents clogs; I monitor this with calipers at various points on the spool. Purity is critical, especially for base materials like PLA, as contaminants lead to nozzle wear and inconsistent melt flow.
For strength-critical applications, I specifically look for enhanced materials like PLA+ or PETG because their mechanical properties far surpass standard PLA. If I am printing something that must hold weight or withstand moderate heat (above 60°C), standard PLA is immediately disqualified. I also always check recommended bed temperatures; a filament that requires a lower bed temperature (50-60°C) is inherently easier to manage and less prone to warping on non-enclosed printers.
Application Types and Material Choices I Recommend
For simple prototyping and aesthetic prints where durability isn’t paramount, standard PLA (like the OVERTURE or SUNLU basic spools) is the clear winner due to its ease of use and low warping risk. I recommend sticking to the cheapest, most accurate PLA you can find for these purposes. However, if you are creating parts for robotics, outdoor equipment, or mechanical assemblies, you absolutely must step up to PLA+ (like the eSUN option) or PETG.
The PLA+ gives you significantly improved tensile strength over normal PLA without demanding major changes in your printing environment. PETG (such as the Creality PETG) is my go-to for parts needing chemical resistance or prolonged exposure to sunlight and moderate heat, though it does require a slightly hotter nozzle and bed, and requires more careful retraction settings to mitigate stringing. I use silk filaments exclusively for decorative art—they are not for functional components.
Your Best 3d Print Filament Questions Answered
What Is the Best 3d Print Filament for Functional Parts?
The best 3d print filament for functional parts is generally eSUN PLA+ or Creality PETG. I found during rigorous stress testing that PLA+ offers significantly improved impact resistance and toughness compared to standard PLA, making it suitable for tools and enclosures. If you need enhanced temperature resistance, PETG is the superior choice, provided you can manage the slightly higher printing temperature and potential stringing issues.
Should I Use PLA or PLA+ for My Everyday Printing Needs?
In my experience, if your budget allows for the small price jump, I strongly recommend using PLA+ over generic PLA for everyday use. PLA+ provides better layer bonding and results in parts that are much less brittle, meaning your test prints and prototypes are less likely to break during handling or installation. For beginners, the marginal strength increase provides valuable forgiveness during the learning process.
What Causes Filament Stringing and How Can I Fix It?
Filament stringing, where thin strands of plastic are left between print areas, is caused by plastic oozing out of the nozzle during travel moves. I usually fix this by tuning two settings: increasing the retraction distance (typically 6-8mm for Bowden setups, 1-2mm for Direct Drive) and reducing the printing temperature by 5-10 degrees C. Running a temperature tower test helps pinpoint the optimal balance.
How Should I Properly Store My 3D Filament to Prevent Moisture Issues?
Filament is highly hygroscopic, meaning it absorbs moisture from the air, which leads to bubbling, poor layer adhesion, and weaker prints. I store all my unused spools in vacuum-sealed bags with fresh desiccant packs. If a spool has been exposed for more than a week, I run it through a dedicated filament dryer for 4-6 hours before printing to ensure optimal material quality.
Is Dimensional Accuracy of +/- 0.02mm Really Necessary?
While many beginners can achieve acceptable results with +/- 0.05mm tolerance, I find that tighter dimensional accuracy like +/- 0.02mm is necessary for professional results and reliability. Highly accurate filament ensures a consistent melt flow rate, which prevents clogs and guarantees that complex parts with tight tolerances (like interlocking joints) fit together precisely as designed.
