SUNLU Filament
Complete product line with live pricing across -- products. One of the largest filament catalogs available, with wide regional availability.
Last updated: May 2026
SUNLU has built one of the broadest filament product lines in the market. From budget PLA at under $10/kg to PEEK at $500/kg, they cover the full spectrum. They're especially known in the community for competitive pricing, frequent sales with MOQ (minimum order quantity) bundles, and wide regional availability. SUNLU filament ships to USA, UK, Germany, France, the broader EU, Canada, and Australia via their Shopify store and third-party retailers like 3DJake.
Unlike brands that use simple material names, SUNLU has built distinct sub-brands within their PLA range: PLA Meta (modified PLA with improved toughness), PLA+ 2.0 (upgraded high speed formula), and a deep specialty finish catalog. This gives them one of the most varied PLA lineups of any brand we track.
SUNLU is one of the most discussed budget filament brands on Reddit. The consensus: good value for the price, wide availability, and the specialty PLA lines (Meta, Silk, Galaxy) are genuinely impressive for the price point. Some users note occasional color consistency issues between batches, but this is common across all budget brands. The PLA Meta line in particular has earned a following for its pastel macaron colors and improved toughness over standard PLA.
Product Lines
SUNLU's bread and butter. Standard PLA is their most affordable filament with one of the widest color selections of any brand. PLA+ adds improved layer adhesion and impact resistance for a small price bump. Together, these two materials account for the bulk of SUNLU's catalog and are the products most often compared to Elegoo.
Both are available in 1kg spools as well as MOQ bundles (typically 3 or 6 rolls). The MOQ bundles drive the per-kg price down significantly, which is how SUNLU achieves some of the lowest prices in our tracker. If you know your color, buying the bundle is almost always the better deal.
PLA+ 2.0 is SUNLU's latest formula revision, optimized for high speed printing (200+ mm/s) while retaining the strength improvements of PLA+. It's positioned between standard PLA+ and their dedicated High Speed line, offering a balance of speed, toughness, and printability. The "2.0" branding signals a genuine reformulation, not just a marketing rename.
Community feedback on PLA+ 2.0 has been positive, with users noting improved flow at higher speeds and better layer adhesion than the original PLA+. Available in a growing color range, though not as extensive as standard PLA+ yet.
PLA Meta is SUNLU's most differentiated product and arguably their strongest sub-brand. It's a modified PLA with improved toughness and impact resistance, positioned between standard PLA and engineering materials. The name "Meta" refers to the material modification, not a finish - though it's best known for its distinctive macaron pastel color palette that's become a community favorite.
What sets PLA Meta apart from generic "tough PLA" is the combination of material properties and curated colors. The pastel tones (lavender, mint, peach, baby blue) print with a smooth matte-adjacent surface that hides layer lines better than glossy PLA. It's found a niche among makers who want prints that look and feel premium without post-processing.
SUNLU's dedicated high speed lineup covers more material variants than most competitors. Beyond the standard HS-PLA and HS-PLA+, they also offer high speed matte PLA and high speed matte PETG. This breadth means you can get high speed formulations in finish variants that other brands only offer at standard speeds.
These filaments are formulated for 200-300 mm/s printing with modified flow characteristics and higher recommended nozzle temperatures (typically 210-230C). The community considers SUNLU's high speed offerings solid budget alternatives to premium brands like Bambu Lab's own filament.
SUNLU's PETG range includes standard, matte, and rainbow variants. The matte PETG is a standout product - it's hard to find from other budget brands and gives functional parts a professional, non-glossy finish. Standard PETG comes in a solid color range for the price point.
PETG is the step up from PLA when you need heat resistance (won't warp in a hot car), better layer adhesion for structural parts, or chemical resistance. SUNLU's PETG pricing undercuts most European brands significantly, especially on the matte variant where comparable products from Prusament or Polymaker are 2-3x the price.
Where SUNLU really flexes is specialty PLA finishes. Their catalog goes deeper than most brands: Silk adds a metallic sheen in a wide color range. Rainbow and Dual-Color transition between colors along the spool. Galaxy has embedded glitter particles. Twinkling adds a subtle sparkle effect. Glow-in-the-dark charges under light. Wood contains real wood fibers. Marble creates stone-like swirl patterns.
These are still PLA under the hood, so they print with the same ease and settings. Prices on specialty finishes are competitive - often 20-40% below equivalent finishes from brands like Polymaker or Prusament. Many specialty finishes are available in MOQ bundles for additional savings.
SUNLU's engineering range is one of the broadest of any budget brand. ABS and ASA cover heat-resistant and UV-stable applications. TPU is available in multiple durometers for flexible parts. Nylon and PA12-CF (carbon fiber reinforced nylon) handle high-stress mechanical applications. PC (polycarbonate) offers exceptional heat and impact resistance. PP (polypropylene) is chemically resistant and fatigue-proof.
PEEK is the standout in this lineup. Very few consumer brands offer PEEK filament at all, and at around $500/kg it's their most expensive product by far. PEEK handles continuous temperatures above 250C and is used in aerospace and medical applications. It's a niche product, but the fact that SUNLU offers it at all speaks to the breadth of their catalog. Not all engineering materials are available in every region.
SUNLU's refill system sells filament without a spool, designed to be loaded onto reusable master spools. This reduces plastic waste and shaves a few dollars off the price per roll. The refill coils are compatible with SUNLU's own reusable spools as well as Bambu Lab reusable spools and most standard 1kg spool holders.
Refills are currently available in PLA and PLA+ in a selection of popular colors. The per-kg savings over spooled equivalents are modest but add up for heavy users who go through dozens of rolls. The environmental benefit is the primary draw - each refill coil eliminates one plastic spool from the waste stream.
Many SUNLU products require a minimum order quantity (MOQ) - typically 3 or 6 rolls. These are marked as bundles on SpoolHound. The per-kg price on MOQ products is often significantly lower than buying individual spools, which is how SUNLU achieves some of the lowest prices in our tracker.
When you see a SUNLU product with a very low per-kg price, check the product details - it likely requires buying multiple rolls. This is great value if you're stocking up on a color you use regularly, but less ideal if you want to sample a single spool. Individual rolls are still available for most materials, just at a higher per-kg price.
SpoolHound tracks SUNLU filament prices across their direct store and third-party retailers including 3DJake. Prices and availability vary by region.

When to choose SUNLU (and when to look elsewhere)
SUNLU sits in the same tier as Elegoo for budget-friendly filament: aggressive pricing, broad catalog, regional warehousing in most countries, vacuum-sealed spools. The differences come down to specific product strengths — SUNLU's TPU and dryer ecosystem are widely considered better than Elegoo's, while Elegoo's Rapid PLA is more talked-about for Bambu high-speed work. Choosing between them is mostly about which materials you need and what's on sale.
You need budget TPU that prints reliably. SUNLU TPU 95A is the most-recommended budget flexible filament on r/3Dprinting. Direct-drive printers handle it at 25-35mm/s, and the price ($20-25/kg) undercuts Polymaker PolyFlex significantly with similar print quality. TPU picks.
You're stocking up via MOQ bundles. SUNLU's 5×1kg and 6×1kg multi-roll bundles hit per-kg prices that no premium brand can match — typically $9-11/kg landed for standard PLA. For print farms or heavy hobbyists who go through filament fast, MOQ deals are the best value-per-kg in the market.
You're running a Bambu / Elegoo Centauri / Prusa XL at 200mm/s+. PLA+ 2.0 is formulated specifically for high-speed printing while keeping PLA+'s impact toughness. Pairs well with Bambu's high-flow profiles.
You want filament drying in your workflow. SUNLU also makes the most-recommended budget filament dryers (S2, S4, FilaDryer 2). Their material supply chain is moisture-aware in ways some budget brands aren't — spools usually arrive measurably drier than equivalent Elegoo or no-name listings.
You care about plastic waste. SUNLU's reusable cardboard refill packs cut spool waste in half. The format doesn't fit the Bambu AMS, but for external spool holders it works the same as a standard spool at $1-2/kg less.
You need premium QC documentation. Same caveat as Elegoo — SUNLU's QC is good in practice but undocumented. Polymaker, Prusament, and Fiberlogy publish more detailed batch and chemistry data when that paper trail matters.
You're printing engineering-grade carbon fibre composites. SUNLU's PETG-CF and PLA-CF are functional but less community-tested than Polymaker Fiberon, eSUN ePA-CF, or Bambu PAHT-CF. For drone arms, robotics frames, or load-bearing engineering parts, dedicated composite brands edge out.
You need ABS or ASA that matches premium brand consistency. SUNLU ABS works on enclosed printers but warps slightly more than Polymaker PolyLite ABS on large parts. For small-to-medium ABS prints, SUNLU is fine; for big enclosure builds, premium brands' low-warp formulations are worth the upcharge. ABS picks.
You need a single 1kg spool quickly. SUNLU's MOQ-bundle pricing model means single-spool pricing is less aggressive than Elegoo's. For one-off purchases without bulk discount, Elegoo or Amazon-stocked Polymaker often beat SUNLU on landed cost for a single 1kg spool.
