PC-ABS (Polycarbonate-ABS blend) is a high-performance engineering filament combining polycarbonate’s exceptional strength and heat resistance with ABS’s ease of printing and toughness. This synergistic blend produces a material with superior mechanical properties suitable for demanding functional applications in automotive, aerospace, and industrial environments.
PC-ABS Material Properties
With tensile strength of 55-65 MPa (higher than ABS and PLA) and impact strength of 40-50 kJ/m² (3-4x higher than standard ABS), PC-ABS is exceptionally durable. The heat deflection temperature reaches 110-120°C at 1.82 MPa, making it suitable for elevated temperature applications. Our PC-ABS HF High Flow grade offers improved processability.
Printing Guidelines
Print at 270-290°C nozzle temperature (hardened steel recommended) with 100-110°C bed temperature using PEI or similar high-adhesion surface. An enclosed printer is essential—target 40-50°C chamber temperature for optimal results.
Aplicações
PC-ABS is used for automotive instrument clusters, functional prototypes, and under-hood components. In aerospace, it’s suitable for interior brackets, ducting, and structural prototypes. Electronics applications include durable housings, connectors, and insulators.
Source PC-ABS Materials
As a specialized source manufacturer, we offer PC-ABS in both filament form for 3D printing and as engineering stock for CNC machining. Our PC-ABS GF20 with 20% glass fiber provides enhanced stiffness. Contactar-nos for technical support and pricing.
PC-ABS 3D Printing — Frequently Asked Questions
Is PC-ABS stronger than regular ABS?
Yes, PC-ABS offers 50-100% higher impact strength (40-50 kJ/m2 vs 20-25 kJ/m2 for ABS) and significantly better heat resistance with HDT of 110-120C at 1.82 MPa. This makes it suitable for under-hood automotive applications and functional prototypes.
Do I need a special nozzle for PC-ABS?
Yes, always use hardened steel or ruby nozzles for PC-ABS since polycarbonate is highly abrasive. Standard brass nozzles will wear rapidly. Increase nozzle temperature by 5-10C vs brass. Nozzle temperature: 270-290C with hardened steel.
Where can I source PC-ABS materials?
Nylonplastic is a specialized manufacturer established in 2005, ISO9001/14001/45001/IATF16949 certified. We supply PC-ABS in both filament for 3D printing and sheet/rod forms for CNC machining. Our PC-ABS HF grade offers improved processability. Contact us for free samples and bulk pricing.
