Head‑to‑Head Comparison
Price and Value
The SUNLU 1 kg black spool offers the lowest cost per kilogram at $12.59, translating to roughly $0.0126 per gram. The 250 g mini‑spool bundle is the most expensive on a per‑gram basis at $54.99 for 1 kg total (four spools), or $0.055 per gram, but it delivers a broad palette without requiring a full‑size spool. Anycubic’s 10 kg bundle costs $103.55, equating to $0.0104 per gram – the best absolute price for bulk users. SUNLU PLA+ 4 kg is priced at $43.34, or $0.0108 per gram, providing premium PLA+ performance at a modest premium. SUNLU white 1 kg sits at $16.14, or $0.0161 per gram, slightly higher than the black 1 kg but still affordable.
Features and Specifications
All products share a 1.75 mm diameter tolerance of ±0.02 mm, ensuring compatibility with most FDM printers. The mini‑spool bundle emphasizes color variety and compact storage, while the black 1 kg spool highlights neat winding and standard 8‑inch diameter. Anycubic distinguishes itself with an intelligent identification chip that auto‑feeds printing parameters to compatible ACE Pro printers. SUNLU PLA+ 2.0 advertises faster melt flow, supporting speeds up to 300 mm/s and improved impact resistance. The white filament provides a bright hue but suffers from a larger central hub that some users report as a cause of spool‑rotation issues.
Customer Ratings and Feedback
Ratings range from 4.3 to 4.7 stars. Anycubic leads with 4.7/5, reflecting strong satisfaction among its smaller reviewer base. SUNLU PLA+ 2.0 follows closely at 4.6/5, buoyed by praise for strength and consistency. The 1 kg black spool and the 250 g bundle both hold 4.4/5, with reviewers highlighting ease of feeding and vibrant colors. SUNLU white trails slightly at 4.3/5, with mixed feedback: many users commend brightness, yet a notable negative review cites spool‑hole size causing layer shifts.
Performance and Reliability
Across the board, users report reliable extrusion, strong layer adhesion and minimal warping. The black 1 kg spool is praised for “no tangles” and “solid surface finish.” The 250 g mini‑spools receive compliments for “smooth printing with standard PLA profiles” and “consistent diameter.” Anycubic’s vacuum‑sealed, pre‑dried filament is described as “the cleanest, least stringing prints of any filament used.” SUNLU PLA+ 2.0’s “strong layer adhesion” and ability to print at high speeds are highlighted by educators and robotics teams. The white filament’s performance is generally good, but the negative review indicates occasional spool‑rotation problems that can lead to layer shifts.
Best Use Cases
- SUNLU 250 g Mini‑Spools: Ideal for hobbyists who need a wide color palette for small prints, prototypes, or multi‑color models without purchasing large spools.
- SUNLU Black 1 kg: Perfect for users who print high volumes of a single color, such as functional parts, enclosures or repeated batch jobs.
- Anycubic 10 kg Bundle: Suited for schools, makerspaces, or small businesses that require many colors in bulk and benefit from the chip‑enabled auto‑settings.
- SUNLU PLA+ 2.0 4 kg: Best for fast‑printing applications, mechanical prototypes, and educational settings where durability and speed matter.
- SUNLU White 1 kg: Good for signage, decorative objects and projects where a bright white finish is essential, provided the printer’s spool holder accommodates the larger hub.

FAQ
- Do these filaments require special storage? All listed filaments are vacuum‑sealed to protect against moisture. For long‑term storage, keep them in a dry box or resealable bag with desiccant.
- Can the Anycubic intelligent chip be used on non‑ACE printers? The chip only auto‑configures on ACE Pro models; on other printers it behaves like a standard PLA filament.
- Is SUNLU PLA+ compatible with standard PLA settings? Yes, but the manufacturer recommends slightly higher nozzle temperatures (205‑220 °C) to exploit its enhanced flow.
- Why does the SUNLU white spool cause layer shifts for some users? Reviewers note the larger central hub can lead to uneven rotation on certain spool holders, increasing pull on the filament and causing occasional layer shifts.
- Which filament is the most economical per gram? The Anycubic 10 kg bundle offers the lowest cost per gram at $0.0104, closely followed by SUNLU PLA+ 4 kg at $0.0108.
- Are the mini‑spools compatible with Bambu Lab AMS? They can be used with AMS after acquiring a compatible 250 g spool adapter; the manufacturer advises checking MakerWorld for adapters.
- Do any of these filaments require a heated bed? While PLA prints well on a non‑heated bed, all products recommend a bed temperature between 50‑65 °C for optimal adhesion.
Conclusion
Each filament examined excels in a specific niche. The SUNLU 250 g mini‑spool bundle shines for color diversity, the SUNLU black 1 kg spool dominates low‑cost single‑color printing, Anycubic’s 10 kg bundle offers bulk value and smart‑chip convenience, SUNLU PLA+ 2.0 provides speed and strength for demanding prototypes, and the SUNLU white 1 kg delivers bright aesthetics when spool compatibility is ensured. For most users, the decision hinges on volume, color needs and printing speed. Overall, Anycubic’s bulk bundle receives the highest overall rating, but SUNLU’s PLA+ 2.0 is the best choice for fast, durable prints. Selecting the appropriate filament based on the outlined use cases will maximize print quality while protecting budget.

Frequently Asked Questions
What are the main differences between SUNLU mini‑spool bundles and the SUNLU 1 kg black spool?
Mini‑spool bundles provide multiple colors in 250 g sizes for variety, while the 1 kg black spool offers a larger single‑color quantity at a lower per‑gram cost.
How does the Anycubic 10 kg multicolor bundle compare in price and quantity to SUNLU options?
The Anycubic bundle supplies a massive 10 kg of mixed colors, typically delivering a lower cost per kilogram than SUNLU’s smaller bundles but with less individual color control.
Which PLA filament offers the best dimensional tolerance for consistent extrusion?
Both SUNLU and Anycubic claim a ±0.02 mm diameter tolerance, but SUNLU’s specifications highlight tighter control, making it slightly more reliable for precision prints.
Are there notable differences in warping and feeding between SUNLU PLA and Anycubic PLA?
SUNLU PLA is marketed as low‑warping and easy‑feeding, whereas Anycubic PLA performs well but users report occasional feeding hiccups on slower extruders.
What factors should I consider when choosing between recycled (environmentally friendly) and virgin PLA filaments?
Consider print quality, color vibrancy, and sustainability goals; recycled PLA may have slightly lower consistency, while virgin PLA typically offers more reliable results.
