التصاق بالمنصة
PETG-CF adheres similarly to standard PETG. Use a textured PEI sheet or apply glue stick on smooth PEI as a release agent. The carbon fibers reduce warping compared to plain PETG, so adhesion is generally easier. Let the bed cool completely before removing prints.

نصائح احترافية لـ PETG-CF
A hardened steel nozzle is mandatory -- never use brass with carbon fiber filaments
Use a 0.5mm or 0.6mm nozzle for the best reliability and flow
Dry PETG-CF before every use -- moisture causes bubbling and weakens carbon fiber bonding
Print 30-40% slower than plain PETG for best surface quality and fiber alignment
PETG-CF excels for functional parts needing stiffness without the high temps of nylon-CF

For prints requiring supports with PETG-CF, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
