PETG-CF is a PETG-based composite material with added carbon fiber. It's suitable when increased rigidity and dimensional stability are required: the part will move less and maintain its shape better. At HEDRAFT, we use PETG-CF for technical fasteners, housings, and components where shape and precision are critical.

PETG – rigidity and stable geometry

PETG-CF is chosen for parts where standard PETG is too elastic, but rigidity and stability are needed. The composite holds its shape better and is suitable for structural components, brackets, and mounting parts.

Where PETG-CF is suitable

• Rigid brackets and mounts (no impact load)

• Parts with geometric requirements : landing, mating, guides

• Housings and panels with minimal deformations

• Technical elements of structures : ribs, reinforcements, racks

• Equipment and fixtures : templates, holders, jigs

• Serial products where dimensional repeatability is important

• Parts that should not “spring” during operation

When PETG-CF is not the best choice

• Strong impacts/drops - sometimes regular PETG is better (it is more “viscous”)

• High wear and load - better PA / PAHT-CF

• Street/UV permanent - better than ASA

• High temperature near heating - ABS/ASA/PAHT-CF (as per the task)

• Flexibility is needed – TPU

Why choose PETG-CF

• Higher rigidity compared to PETG

• Better geometric stability : less deformation on the part

• Repeatability in a series and on large elements

• Technical matte surface (often preferred by customers)

What we need to know before printing PETG-CF

• The part will experience impact or only static load

• Are precise fits and tolerances required?

• Where used: indoors/outdoors

• Is there heating?

• Are metal inserts/threaded bushings required (if fastening unit)

Examples of PETG-CF products

• Reinforced brackets and fasteners

• Housings, panels, mounting elements

• Equipment, conductors, holders

• Parts where shape and rigidity are important

Frequently asked questions:

Is PETG suitable for functional parts?

Yes. PETG is one of the best general-purpose materials for processing parts such as mounts, brackets, housings, and repair parts at moderate temperatures.

Can PETG be used in humid environments?

What to choose: PETG or PETG-CF?

Can PETG withstand high temperatures?

Is PETG stronger than PLA?

PETG is versatile and "flexible". PETG-CF is stiffer and more geometrically stable, but may be less impact resistant. The choice depends on the load and mold requirements.

Yes, this is one of the options for devices for which PETG/PLA is no longer suitable in terms of temperature.

PETG withstands moisture and daily use well. For continuous outdoor use and UV exposure, ASA is more often recommended.

PETG is not the best choice for parts that are near heat sources. If there is heat, choose ABS/ASA or PA.
