QTS PC-ABS Engineering 3D Printer Filament 1.75mm — 101°C Heat Resistant, High Impact, High-Speed Printing
QTS PC-ABS is a high-performance alloy material of PC and ABS, combining PC's high heat resistance (HDT 101°C) and ABS's excellent toughness. Good flowability, higher printing success rate than pure PC, effectively reducing warping and cracking risks. Tensile strength 50 MPa, ideal for industrial applications .
QTS PC-ABS Engineering Filament 1.75mm
The ultimate blend of Polycarbonate (PC) strength and ABS printability. Achieve 101°C heat resistance and 52 MPa tensile strength without the extreme warping of pure PC. Perfect for automotive, electronics, and functional prototyping.
Why Choose QTS PC-ABS Filament?
Superior Heat Resistance
With an HDT of 101°C, it far outperforms standard ABS (80-90°C), making it ideal for parts exposed to high temperatures like car interiors and electronic housings.
Exceptional Impact Strength
Boasting an Izod notched impact strength of 38 kJ/m², it absorbs shocks and vibrations better than pure PC or ABS, preventing brittle fractures.
Easier to Print than Pure PC
The ABS blend significantly improves flow and reduces internal stress, minimizing the severe warping and cracking typically associated with pure Polycarbonate.
High-Speed Printing
Supports print speeds of 100-300 mm/s, drastically reducing print times compared to pure PC (which often requires slow 40-60 mm/s speeds).
Excellent Post-Processing
Delivers a smooth, fine surface finish that is highly compatible with metal plating, painting, and polishing for premium end-use products.
Dimensional Stability
High flexural modulus (2060 MPa) ensures parts maintain their shape and precision under load, crucial for mechanical components.

How to Print PC-ABS (Best Practices)
- Drying is Mandatory: PC blends absorb moisture rapidly. Dry at 70-80°C for 4-6 hours before printing to prevent bubbling, stringing, and weak layer adhesion.
- Enclosure Required: To prevent warping and layer splitting, especially on large parts, use a fully enclosed printer to maintain a stable, warm ambient temperature.
- Nozzle Temperature: 230°C - 260°C (Adjust based on printer speed and flow capabilities).
- Bed Temperature: 60°C - 100°C. A hotter bed improves first-layer adhesion and reduces warping.
- Cooling Fan: Keep fan speeds low (0-30%). Excessive cooling will cause layer separation and warping.
- Print Speed: 100 - 300 mm/s.

Frequently Asked Questions
Why does PC-ABS print faster than pure PC?
The addition of ABS significantly improves the melt flow characteristics of the material. This allows QTS PC-ABS to be printed at speeds of 100-300 mm/s, whereas pure PC often struggles above 60 mm/s.
Do I need an all-metal hotend?
While PC-ABS prints at 230-260°C, which is at the upper limit of PTFE-lined hotends, an all-metal hotend is highly recommended for safe, long-term printing at these temperatures.
Can I smooth PC-ABS with acetone?
Because it contains ABS, PC-ABS can be smoothed with acetone vapor, though the effect may be slightly less pronounced than with pure ABS. It also sands, paints, and electroplates exceptionally well.
