If you've been frustrated with standard PLA filament that cracks, warps, or just doesn't stand up to functional parts, you're not alone. Most 3D printing enthusiasts eventually hit that wall where basic materials just don't cut it for demanding applications. That's exactly where SUNLU's PLA+2.0 filament enters the picture – and it's changing the game for serious makers and professionals alike.
Having tested numerous filaments over the years, I can confidently say that SUNLU's 10KG PLA+2.0 bulk pack represents one of the best value propositions in the 3D printing market right now. With 69 verified sales and a solid 4.5-star rating, this isn't just another filament option – it's a solution designed for those who print frequently and demand reliability. At $92.33 for 10KG (a 33% discount from the original $137.80), the price per kilogram comes out to just $9.23, which is exceptional for premium-grade filament.
The "plus" in PLA+ isn't just marketing speak – SUNLU has genuinely engineered improvements that address common pain points in 3D printing. Where standard PLA tends to be brittle and prone to cracking, the PLA+2.0 formulation offers 2-3 times the toughness of regular PLA filaments. I've personally used this filament for functional parts like tool handles, mechanical components, and even outdoor fixtures, and the difference is noticeable immediately.
One of the standout features is the printing speed capability. While most PLA filaments max out around 60-100mm/s, SUNLU's PLA+2.0 can handle speeds up to 300mm/s without sacrificing print quality. This is a game-changer for production environments or anyone who values time efficiency. During my testing, I pushed my printer to 250mm/s on larger, less detailed prints and was amazed at how well the filament performed – minimal stringing, excellent layer adhesion, and consistent extrusion.
Let's break down the technical specifications and what they actually mean for your printing experience:
| Specification | Details | User Benefit |
|---|---|---|
| Diameter | 1.75mm | Compatible with most modern FDM printers |
| Tolerance | ±0.02mm | Minimizes clogging and ensures consistent extrusion |
| Print Speed | 50-300mm/s | Faster printing without quality loss |
| Nozzle Temperature | 205-215°C | Energy efficient and easy to dial in |
| Bed Temperature | 50-65°C | Excellent adhesion with minimal warping |
| Net Weight | 1kg per roll | Standard sizing for easy storage and handling |
| Material | PLA+2.0 | Enhanced toughness and reduced brittleness |
The ±0.02mm tolerance is particularly impressive. In practical terms, this means exceptionally consistent diameter throughout the entire spool, which translates to fewer clogs, more reliable extrusion, and ultimately less failed prints. I've run through several kilograms of this filament without a single clog-related print failure – something I can't say about many other filaments in this price range.
After extensive testing across multiple printer models including Creality, Prusa, and Anycubic machines, the SUNLU PLA+2.0 consistently delivered excellent results. The filament's low shrinkage characteristic means minimal warping even on larger prints – I successfully printed a 200mm x 200mm calibration plate with virtually no corner lifting, which is impressive for any PLA variant.
The surface finish quality deserves special mention. Prints come out with a noticeably smoother surface compared to standard PLA, with reduced visible layer lines and a more professional appearance. This makes it ideal for display models, prototypes, and finished products where appearance matters. The bright color options maintain their vibrancy through the printing process, producing visually appealing results that look more expensive than they actually are.
Where this filament truly shines is in functional applications. I printed several mechanical parts including gears, brackets, and tool handles that subjected to actual use stress. The enhanced toughness meant these parts survived impacts and sustained loads that would have shattered standard PLA components. The manufacturer's claim of 2-3 times increased toughness appears legitimate based on my stress testing.
For those wondering about the optimal printing parameters, I found the sweet spot at 210°C nozzle temperature and 60°C bed temperature. The filament adheres beautifully to both PEI and glass beds without excessive stickiness – parts release cleanly when the bed cools down. If you're looking to get the best results with this filament, start with these settings and adjust based on your specific printer characteristics.
The SUNLU 10KG bulk pack is ideally suited for specific user groups who will maximize its value proposition:
If you're printing regularly – whether for personal projects, small business products, or educational purposes – the bulk pricing makes tremendous financial sense. At $9.23 per kilogram compared to the typical $20-25 for premium filaments, the savings add up quickly. I know makers who go through 1-2kg per week; for them, this bundle represents several months of printing at a fraction of the cost.
Schools, libraries with maker programs, and shared workshop spaces need reliable, affordable filament that can withstand varied use by multiple people. The consistency of SUNLU's PLA+2.0 means less troubleshooting and failed prints, which is crucial in educational settings where time is limited. The environmental aspect of the reusable materspool also aligns well with institutional sustainability goals.
For professionals producing functional prototypes, product models, or small batch production parts, the enhanced mechanical properties provide genuine advantages over standard PLA. The ability to print at higher speeds without quality loss directly translates to increased throughput and lower production costs. Many users don't realize that premium filament at this price point can significantly impact their bottom line.
When compared to other popular filaments in the market, SUNLU's PLA+2.0 holds its own remarkably well:
HATCHBOX is often considered the gold standard for reliable PLA filament, but it typically costs $22-25 per kilogram. While HATCHBOX offers excellent consistency, SUNLU's PLA+2.0 provides similar print quality with enhanced toughness at less than half the price per kilogram in bulk. The choice becomes clear for volume users.
OVERTURE's PLA Pro is another popular "enhanced" PLA option priced around $20-23 per kg. Both filaments offer improved mechanical properties over standard PLA, but SUNLU's 300mm/s print speed capability gives it an edge for users looking to maximize printing efficiency. The reusable materspool system also provides additional value that OVERTURE doesn't offer.
While cheaper generic filaments abound on the market, they often suffer from inconsistent diameter, poor winding, and unreliable mechanical properties. SUNLU's strict ±0.02mm tolerance and mechanical winding process ensure reliability that cheap filaments simply cannot match. The slight premium over bottom-tier filaments is more than justified by the dramatically reduced failure rate.
For those comparing options, the value equation clearly favors SUNLU when buying in bulk quantities.
One of the most innovative aspects of SUNLU's offering is the reusable materspool system. Unlike traditional spools that become waste after use, the materspool can be refilled with SUNLU's refill packs, significantly reducing plastic waste. This is particularly valuable for high-volume users who might go through dozens of spools annually.
The filament itself is environmentally friendly and biodegradable, made from renewable resources rather than petroleum-based materials. The manufacturing process emphasizes sustainability, which aligns with the values of many in the 3D printing community who are conscious about their environmental impact.
Vacuum packaging with desiccant ensures the filament arrives moisture-free and ready to use. I've stored opened spools for several weeks in moderately humid conditions without noticeable degradation in print quality – though for long-term storage, I still recommend using sealed containers with desiccant.
Let's break down the financials to understand the true value proposition. At the discounted price of $92.33 for 10kg, you're paying $9.23 per kilogram. Compare this to:
Even if you experience a slightly higher failure rate than with premium filaments (though my testing showed comparable reliability), the cost savings still heavily favor SUNLU's bulk offering. For a user printing 5kg monthly, the annual savings would exceed $750 compared to using standard premium filaments.
The reusable materspool system adds further value. Assuming each traditional spool costs $1-2 to manufacture (and ultimately dispose of), the environmental and economic benefits compound over time. Serious users should consider this bulk purchase as a long-term investment rather than a simple consumable purchase.
Based on extensive testing and analysis, here's my guidance on who should consider this product:
PLA+2.0 is an enhanced formulation that offers significantly improved toughness and impact resistance – typically 2-3 times stronger than standard PLA. It also allows for higher printing speeds and exhibits less warping while maintaining the easy printability of regular PLA.
This filament works with any FDM/FFF 3D printer that uses 1.75mm filament, including popular brands like Creality, Prusa, Anycubic, Artillery, and most others on the market. Always check your specific printer's requirements.
For long-term storage, keep unopened vacuum-sealed packages in a cool, dry place. Once opened, store spools in airtight containers with desiccant to prevent moisture absorption, which can affect print quality.
While PLA is generally considered food-safe material, 3D printed parts have layer lines that can harbor bacteria. We don't recommend using any 3D printed items for food contact without proper sealing and treatment.
Start with the recommended settings (210°C nozzle, 60°C bed) and adjust based on your specific printer. Ensure proper extrusion calibration and bed leveling. The consistent diameter typically minimizes extrusion-related issues.
The reusable materspool should work with most printers that accept standard spool sizes. However, some enclosed printers with limited space might have compatibility issues – check your printer's specifications.
This depends entirely on your printing volume. For casual users, 10kg could last a year or more. For serious makers or small businesses, it might last 2-3 months. Consider your average monthly consumption when deciding.
