What is SUNLU PC-ABS? An introduction to this versatile filament
SUNLU PC-ABS is a high-quality alloy filament made from a blend of approximately 70% polycarbonate (PC) and 30% ABS. This strategic composition combines the strengths of both materials: the renowned heat resistance and stiffness of PC combined with the ease of processing and impact resistance of ABS. The result is a 3D printing filament that is ideal for parts that need to withstand high temperatures, mechanical stress, and everyday wear and tear.
Unlike standard ABS, which can warp or decompose under heat, PC-ABS remains stable up to 110 °C, making it suitable for environments with high thermal stress. The smooth surface reduces the need for post-processing, while its compatibility with metal coatings allows for advanced finishing techniques such as painting or metallization. SUNLU PC-ABS is available in a diameter of 1.75 mm – the standard for most FDM printers – and has been designed for flawless extrusion, minimizing issues like nozzle clogs or stringing.
This filament represents SUNLU's ongoing commitment to pushing the boundaries of materiality. By optimizing the PC-ABS ratio, they have achieved a perfect balance between technical performance and printability, making it accessible even for users with entry-level printers.
Technical properties and performance of SUNLU PC-ABS
The most important technical features of SUNLU PC-ABS make it an excellent choice.
Material composition and mechanical properties
SUNLU PC-ABS is an alloy that optimizes durability and user-friendliness. The 70% PC content ensures excellent stiffness and dimensional stability, reducing thermal warping even in demanding prints. The 30% ABS content increases toughness and offers superior impact resistance – ideal for parts that need to withstand drops or impacts.
In terms of heat resistance, this filament is impressive with a continuous operating temperature of up to 110 °C. This is a significant improvement over pure ABS (typically approx. 80–90 °C) and can compete with more expensive technical plastics. The material's low tendency to warp ensures precise dimensions with tight tolerances, minimizing post-print corrections.
Surface quality and aesthetics
One of the most praised aspects of SUNLU PC-ABS is its exceptional surface finish. The prints are characterized by a smooth, uniform texture that can compete with injection-molded parts – ideal for prototypes where appearance is key. The low ooze and minimal stringing of the filament ensure clean, professional results, even with complex geometries.
Also noteworthy is its compatibility with surface treatments. The adhesive surface bonds well with paints, coatings, and metal platings, enabling custom surface designs in automotive or consumer goods.
Overall performance metrics
-
Heat resistance: Continuous up to 110 °C.
-
Impact resistance: Enhanced by ABS for better shock absorption.
-
Stiffness: PC-based for structural integrity.
Dimensional accuracy: High precision with low shrinkage.
These properties are backed by SUNLU's quality assurance, which guarantees that every spool delivers consistent results.
Recommended print parameters for optimal results
To unlock the full potential of SUNLU PC-ABS, the correct printer settings are crucial. Here is a detailed guide based on SUNLU's recommendations:
-
Nozzle temperature: 260 °C – 280 °C. This range ensures a steady print flow without loss of quality.
-
Bed temperature: 100 °C – 110 °C. Promotes strong adhesion and reduces warping.
-
Enclosure temperature (optional): 90 °C – 100 °C, especially for large prints to avoid uneven cooling.
-
Print speed: 50 mm/s – 230 mm/s, adjustable depending on model complexity – slower for intricate details.
-
Cooling fan: Off or low (0–20%) to maintain material integrity during layer building.
-
Build plate: Compatible with most surfaces. For improved adhesion, apply a thin layer of adhesive (e.g., Magigoo or glue stick).
For oversized models, an enclosed printer with a heating capacity of 90–100 °C is strongly recommended to avoid cracking due to thermal stress. Always start with a calibrated machine and dry filament. SUNLU recommends storing spools in sealed containers with desiccant to prevent moisture absorption, which can lead to bubbling or weak layers.
These parameters make SUNLU PC-ABS versatile for standard FDM machines, from budget models to industrial equipment.
