Choose PET-CF when stiffness, dimensional stability, and better heat performance justify a premium over PETG-based options.
PET-CF 3D printing service
Engineering PET-CF parts for demanding use.
PET-CF is the most technical material in this service mix. Use it when stiffness, dimensional stability, and stronger engineering performance matter more than easy printing behavior.
Print-ready STL, STEP, or STP files. CAD repair or model creation is paid work and priced before it begins.

| Part-performance property | Manufacturer-reported value |
|---|---|
| Density | 1.30 g/cm3 |
| Composition | PET with 15% carbon fiber |
| Tensile strength (XY) | 74 MPa unannealed; 73 MPa annealed |
| Tensile strength (Z) | 35 MPa unannealed |
| Young's modulus (XY) | 5950 MPa unannealed; 6700 MPa annealed |
| Young's modulus (Z) | 3400 MPa unannealed |
| Elongation at break (XY) | 2.5% unannealed; 1.5% annealed |
| Elongation at break (Z) | 1.15% unannealed |
| Charpy impact strength | 9 kJ/m2 unannealed; 4.8 kJ/m2 annealed |
| Flexural strength | 116 MPa unannealed; 115 MPa annealed |
| Flexural modulus | 5600 MPa unannealed; 5900 MPa annealed |
| Vicat softening temperature | 220 C |
| Glass transition temperature | 80 C |
| Izod impact | 36 kJ/m |
| HDT at 1.8 MPa | 76.6 C unannealed; 118 C annealed |
| HDT at 0.45 MPa | 86.7 C unannealed; 176 C annealed |
| Water absorption | 0.5% |
These are typical material values from manufacturer testing, usually on standardized specimens. Printed-part results vary with geometry, load direction, wall thickness, infill, environment, and production method. HDT is a comparison point—not a guaranteed continuous-use temperature.
Have a specific temperature, load, chemical, wear, or compliance requirement? Ask for an application review before ordering so the recommendation accounts for the actual part—not only a filament datasheet.
