Description
High-temperature PET reinforced with chopped carbon fiber; distinct from PETG-CF.
Common use cases
Precision fixtures, structural components, tooling, and heat-resistant functional parts.
Advantages
High stiffness; good dimensional stability; better heat capability than PETG-based materials; relatively low creep.
Disadvantages
Requires high processing temperatures; abrasive; must be dried; more demanding than PETG-CF.
Printing tips and recommendations
Use a hardened 0.6 mm nozzle and dry thoroughly. Print with a warm, stable enclosure and a compatible high-temperature build surface. PET-CF is suited to stiff, dimensionally stable parts; use multiple walls and orient the model to keep principal loads within the layer plane.
X2D guidance
Use the main hotend, hardened 0.6 mm nozzle, and a thoroughly dried spool. This is an advanced engineering material rather than an everyday PETG replacement.
Support-material guidance
Support for PA/PET (preferred interface); PET-CF for ordinary supports; hardened nozzle and dry-feed required.
