SUNLU Filament

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.
