eSUN High Speed PLA+ Filament Review: The Workhorse for Fast Printers

The eSUN High Speed PLA+ filament adheres to a standard 1.75mm diameter, with owners reporting consistent dimensional accuracy. This precision is critical for the demanding feed rates of modern high-speed printers, preventing extruder skips and flow inconsistencies. The material itself is an enhanced PLA formulation, designed to withstand the thermal and mechanical stresses of rapid extrusion without significant degradation in strength or print detail. Users frequently cite its increased durability over conventional PLA, making printed parts more resilient.

One recurring note pertains to the spool itself. eSUN employs a cardboard spool, an increasingly common choice for sustainability reasons. While many users appreciate this, some have minor quibbles about its handling or compatibility with specific AMS (Automatic Material System) units, though most report it works without issue. The consistent winding on the spool is a benefit, preventing tangles and ensuring smooth material delivery, a crucial factor when printing at speed where any snag can lead to print failure.

A significant advantage for the eSUN High Speed PLA+ is its straightforward integration into existing high-speed printer workflows. Owners across various platforms, including Bambu Lab A1/X1/P1P and Creality K1, report that the filament performs well even with generic PLA profiles, although some fine-tuning for temperature may be beneficial. The filament typically arrives vacuum-sealed and dry, mitigating the need for immediate drying before use, which streamlines the setup process.

Users emphasize that successful high-speed printing still relies on fundamental principles, such as a clean print bed. While the filament generally exhibits good adhesion, some long-term users recommend a glue stick for particularly large or complex prints to ensure complete bed bonding. This indicates a "process maturity" expectation: the filament performs well, but it does not completely absolve the user from proper print preparation. Its ability to print immediately "out of the bag" and its low propensity for clogging contribute to a user-friendly experience, minimizing the common frustrations associated with new filament brands.

Performance is where the eSUN High Speed PLA+ truly distinguishes itself. Owners consistently achieve print speeds ranging from 100mm/s on upgraded older machines to the full 300mm/s capabilities of newer high-speed printers without significant loss of quality. The filament handles these speeds with minimal stringing and maintains structural integrity. Crucially, layer adhesion is frequently lauded as excellent, producing strong, functional parts. The enhanced toughness of the PLA+ formulation is often highlighted, with users noting that printed objects feel sturdy and are less prone to breakage.

Print quality, even at speed, remains high, with smooth surfaces and sharp details. Several users specifically mention the lack of visible layer lines, even on intricate models, indicating superior extrusion consistency and cooling performance. While some owners occasionally mention a preference for a more matte finish, the overall aesthetic outcome is well-received. This consistent, high-fidelity output under demanding conditions suggests that the filament delivers on its core promise of enabling rapid, reliable production.

The eSUN High Speed PLA+ operates primarily within the existing open-source and proprietary slicer ecosystems without requiring specialized software. Users report success using standard PLA or PLA+ profiles in popular slicers like PrusaSlicer, Cura, and Bambu Studio, with minor temperature adjustments often being the only change. This plug-and-play compatibility is a significant advantage, reducing the learning curve and configuration effort for users migrating from other PLA variants.

Its compatibility with various high-speed printer brands, including Bambu Lab and Creality, indicates a broad "printer-agnostic" approach, which is beneficial in a market where manufacturers often push their own brand of filament. The filament's consistent diameter and winding also contribute to smooth feeding in AMS units, expanding its utility within multi-material printing setups. This ease of integration into diverse hardware and software environments underpins its appeal as a versatile, dependable option.

The eSUN High Speed PLA+ consistently garners praise for its value proposition. Positioned in the mid-range for filament pricing, typically under $20 per kilogram, it delivers performance comparable to more expensive alternatives. Owners frequently highlight this balance of cost-effectiveness and high-quality output as a primary reason for repeat purchases.

Reliability is another strong theme. Users report minimal issues with clogs, tangles, or brittleness, even after long periods of use. The filament's ability to consistently perform without intervention or print failures translates directly into saved time and material, enhancing its overall value. Many owners consider it a go-to choice for functional parts due to its combination of strength, print quality, and dependable performance. This consistent positive feedback on reliability and affordability establishes the eSUN High Speed PLA+ as a robust, long-term solution for enthusiasts and professionals alike.
