The ESUN 3D printing filament EPLA-ST175N1 is a PLA-based filament specifically developed for use in FDM 3D printers. It is an enhanced PLA material referred to as Super Tough, offering higher impact toughness and improved mechanical properties compared to standard PLA. The filament has a diameter of 1.75 mm and is supplied on a spool with a weight of 1 kg. The color is Natural, corresponding to a light, almost white shade. It is suitable for applications requiring high printing accuracy and mechanical robustness, such as prototyping, model making, or producing functional models.

Applications
This filament is suitable for use in FDM 3D printers that use 1.75 mm filament. Due to its enhanced mechanical properties, particularly high impact toughness, it is especially suitable for parts subjected to mechanical stress, such as joints, brackets, or moving components. Its high printing accuracy also makes it ideal for detailed models and precise parts. The heat deflection temperature of 52 °C limits its use to applications where no higher temperatures occur.

Features and Specifications in Detail
The filament features high tensile strength of 34.3 MPa and elongation at break of 90%, indicating good elasticity and resistance to crack formation. The notched impact strength is 63 kJ/m², meaning the material is less brittle and less likely to break under sudden loads or impact stress. The tolerance of ±0.03 mm ensures uniform filament diameter, which is crucial for stable and error-free print quality. The density is 1.23 g/cm³, which is typical for PLA materials.

Technology Explained Simply
The filament is processed at a printing temperature of 210 to 230 °C, with the optimal temperature varying depending on the printer model and individual settings. The print bed temperature ranges from 45 to 60 °C, ensuring good adhesion of the filament to the build platform and preventing warping. The high impact toughness and improved mechanical strength result from a special formulation of the PLA material, which reduces the likelihood of breakage under mechanical stress. The heat deflection temperature of 52 °C means the material may deform at temperatures above this value, which should be considered for outdoor applications or high ambient temperatures.

Compatibility and Accessories
The filament is compatible with all FDM 3D printers that use 1.75 mm filament. No special accessories are required, as it can be used standardly in 3D printers. Using heated beds that reach the recommended bed temperature of 45 to 60 °C is recommended to ensure optimal adhesion. No specific accessory products are mentioned in the sources that must be combined with this filament.

Installation and Mounting
Installation involves loading the spool into the filament supply mechanism of the 3D printer. The spool has a diameter of 200 mm and a width of 64 mm, fitting standardly in most printers. The packaging dimensions are 205 x 215 x 75 mm, and the total weight of the packaged spool is 1.46 kg. The spool is designed to fit easily into most 3D printers without requiring additional holders or modifications.

Operational Advantages
The high printing accuracy and low tolerance of ±0.03 mm result in stable and error-free print quality. The improved mechanical strength and impact toughness enable the production of parts that can withstand mechanical stress. The processing temperature is within the typical range for PLA, meaning easy handling and low requirements for printer settings. The manufacturer's warranty is 12 months, indicating the quality and reliability of the product.
