This means parts made from it have higher rigidity, maintaining shape under load, particularly suitable for structural parts and mechanical components requiring high rigidity. Carbon fiber addition not only enhances mechanical performance but also improves durability, allowing parts to maintain performance during long-term use.

2️⃣ High Strength and Low Warping - Excellent Dimensional Stability

QTS PETG-CF filament features 55 MPa tensile strength and 80 MPa bending strength, providing excellent mechanical performance. Low shrinkage rate (approximately 0.5%) ensures dimensional stability and reduces warping issues. This makes PETG-CF particularly suitable for manufacturing precision parts and mechanical components, ensuring dimensional accuracy and structural stability. Compared to other carbon fiber reinforced materials, PETG-CF has fewer warping issues and higher print success rates.

3️⃣ Excellent Heat Resistance - 75°C Heat Deflection Temperature

QTS PETG-CF filament's heat deflection temperature (HDT) reaches 75°C, offering better heat resistance compared to standard PETG (typically 60-70°C). This means parts made from it can maintain stable performance at higher working temperatures, particularly suitable for heat-resistant applications. For example, automotive modification parts, heat-resistant shells, etc. Compared to PC-ABS's 101°C, PETG-CF, while slightly lower in heat resistance, offers better processability and cost-effectiveness.

4️⃣ Matte Finish - Fine Appearance, Excellent Layer Line Concealment

QTS PETG-CF filament's finished surface has a matte texture with fine appearance and less visible layer lines. This is because carbon fiber addition changes the material's surface characteristics. Compared to glossy PETG, matte finish is more suitable for industrial-grade applications, concealing print layer lines and enhancing product visual effect. Matte finish also offers anti-slip and fingerprint-resistant benefits, particularly suitable for parts requiring high aesthetic quality.

5️⃣ Low Shrinkage Rate - Easy Forming, Reduced Warping

QTS PETG-CF filament has a shrinkage rate of approximately 0.5%, far lower than other high-performance materials. Low shrinkage means less material shrinkage during cooling, resulting in fewer warping issues. This makes PETG-CF particularly easy to form with high print success rates.
