SUNLU PLA vs iSANMATE ASA Specs
printing technology
SUNLU offers PLA, a material known for being reliable, versatile, and easy to use. It is ideal for beginners and experienced users alike. The brand highlights that its filament is neat wound to reduce tangles and jams. iSANMATE provides ASA, a material designed for durability. It offers exceptional UV, weather, mechanical, and thermal resistance. This makes it suitable for functional parts that need stability in different temperature environments. You choose PLA for ease of use and ASA for rugged outdoor performance.
print speed
Both brands list a maximum print speed of 100mm/s. SUNLU recommends a printing speed range of 50-100mm/s for its PLA filament. This allows for moderate to fast printing while maintaining quality. iSANMATE recommends a speed range of 30-100mm/s for its ASA filament. The lower end of iSANMATE's range suggests that slower speeds may be beneficial for this specific material to ensure adhesion and detail. Both allow you to push speeds up to 100mm/s, but iSANMATE suggests starting slower.
compatible material
SUNLU specializes in PLA filament. PLA is a standard thermoplastic that is widely compatible with almost all 1.75mm FDM 3D printers. It is a general-purpose material for prototyping and decorative items. iSANMATE specializes in ASA filament. ASA is an engineering-grade plastic known for its strength and resistance to environmental factors. It is compatible with most consumer and industrial 3D printers. If you need simple prints, SUNLU is the choice. If you need durable, functional parts, iSANMATE is the choice.
build quality
SUNLU emphasizes its self-developed neat winding device, which ensures a 100% neat rate. This reduces the risk of tangles and jams during printing, providing a smoother experience. The filament has dimensional accuracy of +/- 0.02mm. iSANMATE focuses on vacuum-sealed packaging with desiccant to maintain performance. It also claims dimensional accuracy of +/- 0.02mm. While SUNLU highlights the physical winding quality, iSANMATE highlights the protective packaging. Both ensure consistent diameter for reliable extrusion.
everyday use
SUNLU PLA is recommended for indoor use with a nozzle temperature of 200-230°C and a bed temperature of 50-65°C. It is suitable for general enthusiasts and does not require special ventilation. iSANMATE ASA requires higher temperatures, with a nozzle range of 240-270°C and a bed temperature of 80-100°C. It is recommended to print in a closed environment and use glue on the bed. ASA is better for outdoor items due to UV resistance, while PLA is better for indoor models.
Choose SUNLU or iSANMATE for Your Print
Beginners printing general models
SUNLU PLA is easy to use and reliable for most projects. Its recommended print speed of 50-100mm/s and bed temperature of 50-65°C make it forgiving.
