eSUN Filament
Live pricing across -- products. One of the most established filament manufacturers, known for consistent quality and wide material range.
Last updated: March 2026
eSUN is one of the longest-running filament manufacturers in the 3D printing space. Founded in Shenzhen, they've built a reputation for reliable, no-fuss filament across a wide material range. Their products are primarily available in Europe through 3DJake, covering the UK, Germany, and France. With materials spanning from standard PLA to engineering-grade carbon fiber composites, eSUN offers one of the broadest catalogs in the budget segment.
eSUN is one of the original budget filament brands and has been a community staple for years. Their PLA+ in particular is frequently cited on Reddit as the benchmark for what enhanced PLA should be - strong layer adhesion, consistent diameter, and reliable performance at a competitive price. Their PETG is also well-regarded, especially in Europe where they have strong distribution through 3DJake. eSUN is considered a step up from the most affordable options (Elegoo, SUNLU) while still being firmly in the budget category.
Product Lines
The product that defines eSUN. PLA+ (also marketed as PLA Pro in some regions) is an enhanced PLA with improved toughness, better layer adhesion, and reduced brittleness compared to standard PLA. It prints at similar temperatures to regular PLA and requires no special hardware, making it an easy upgrade for anyone already printing PLA.
Community consensus is clear: eSUN PLA+ is the benchmark. When someone on Reddit asks "what PLA+ should I buy?", this is consistently the top answer. The slight matte surface finish is a bonus that many users prefer over the glossy look of standard PLA.
eSUN's metallic and silk finish PLA line. eSilk produces a shiny, metallic sheen on printed parts that looks impressive without any post-processing. Available in gold, silver, copper, bronze, and a range of other metallic colors. Popular for decorative prints, vases, and display pieces where visual impact matters.
The silk finish does come with trade-offs: slightly reduced layer adhesion and less structural strength compared to standard PLA or PLA+. Best suited for aesthetic prints rather than functional parts.
eSUN's matte finish PLA, positioned as a more affordable alternative to Polymaker's Panchroma matte range. Produces a smooth, non-reflective surface that hides layer lines effectively. Made with recycled content and ships on cardboard spools, similar to the eco-friendly approach pioneered by Polymaker.
Community feedback is generally positive for the price point. The matte finish is not quite as refined as Polymaker's but represents strong value for users who want matte PLA without the premium price tag.
eSUN's high-speed PLA, formulated for the new generation of fast printers like the Bambu Lab P1S, X1C, and Creality K1 series. Designed to maintain print quality at speeds of 300mm/s and above, with improved flow characteristics and faster crystallization to prevent issues at high throughput.
As high-speed printers become the norm, HS-rated filaments are increasingly important. eSUN's entry is competitively priced against Elegoo's Rapid and other high-speed PLAs in the budget segment.
eSUN's toughened PLA for functional parts that need to survive impact and stress. ePLA-ST sits above PLA+ in the toughness hierarchy, targeting users who need PLA's ease of printing but with significantly improved impact resistance. Competes with Polymaker's PolyMax PLA in the super-tough PLA category.
Community reports suggest ePLA-ST is a genuine step up from PLA+ for mechanical applications, though availability is more limited than the flagship PLA+ line.
One of eSUN's most unique products. ePLA-LW is a foaming PLA that expands during printing, producing parts that are significantly lighter than standard PLA at the same dimensions. At the right temperature (around 230C), it can expand to nearly twice its normal volume, creating a lightweight foam-like internal structure.
This is a niche product with a dedicated following in the RC plane and drone community, where weight savings are critical. It's also used for large decorative prints where reducing material usage and weight matters. Not a general-purpose filament - it requires specific temperature tuning and slicer adjustments to work properly.
eSUN's engineering range for demanding applications. ePA (Nylon) and ePA-CF (carbon fiber reinforced nylon) target structural parts that need heat resistance and mechanical strength. ASA is their UV-stable option for outdoor use. ABS-ESD is an antistatic variant for electronics handling and manufacturing environments.
These are serious materials for users who have moved beyond PLA and PETG. The ePA-CF in particular competes well with more expensive options from Polymaker and Bambu Lab in the carbon fiber nylon category.
eSUN's flexible filament range covers multiple Shore hardness levels. eTPU-95A is their standard flexible option - firm enough to print reliably on direct drive extruders while producing parts with good elasticity. eTPE offers a different flexibility profile, and ePEBA is a premium flexible material with excellent elastic recovery.
The eTPU-95A is the most popular of the three, well-suited for phone cases, gaskets, seals, and vibration dampening mounts. Prints best at slower speeds (20-40mm/s) with a direct drive extruder.
