About carbon fibre
Carbon fibre consists of small strands (roughly 5-10 microns in diameter) of mainly carbon atoms. We use a PET-based composite containing 20% recycled carbon fibres to produce attractive, dimensionally stable prints. The filament boasts an impressive strength-to-weight ratio making it ideal for a range of applications.
Advantages of carbon fibre
High heat tolerance
Our carbon fibre PETG filament is heat resistant up to 80°C. Not only does this aid the 3D printing process and prevent shrinkage, it also means your final parts will be able to withstand higher temperatures.
Lightweight yet strong
Expect lightweight prints with a high tensile strength and stiffness. Parts will be rigid, durable, and impact resistant. Its strength makes it a good option for prototyping designs that will eventually be injection moulded.
Chemical resistance
Carbon fibre is incredibly versatile due to its resistance to a number of harmful substances. These include chemicals, oil, and grease. These corrosion-resistant properties are perfect for end-use parts.
Carbon fibre use cases
- Car parts & other automotive applications
- Potential substitute for metal
- Sporting equipment
- Aerospace components
- Functional prototypes
Things to consider
- Increased brittleness
- Requires an experienced printing technician
- Can be abrasive
- Limited colour options

Matte finish
A key selling point of carbon fibre 3D prints is the sleek matte black finish. The layer lines typically associated with FDM printing also blend together to the point that they are barely noticeable. Rather than a shiny finish, yours parts will feel slightly rough, closer to an SLS print.
Carbon Fibre vs PETG
By reinforcing standard PETG filament with carbon fibre, you greatly increase its mechanical integrity. Strength, stiffness, and dimensional stability all improve significantly, without adding weight. It also changes the finish from a smooth, glossy texture to a grainy, matte.

FAQ
Is carbon fibre PETG chemical resistant?
Yes, carbon fibre offers a high chemical resistance. It can also tolerate temperatures up to 80°C.
How fast does carbon fibre print?
Depending on the delivery speed you select, this is when you can expect to receive your Carbon Fibre 3D prints:
- Express (1-3 business days)
- Standard (3-6 business days)
- Economy (10 business days)
Is carbon fibre expensive?
Carbon fibre is slightly more expensive than other FDM 3D printing materials due to its enhanced quality. However, it is still very affordable and makes for a cost effective alternative to creating parts in metal.
How strong is carbon fibre?
Our carbon fibre infused PETG has an impact strength of 3.8 kJ/m2 under the ISO 179 testing method. Under ISO 527, it scored a tensile strength at yield of 52.5 MPa, 4.2% strain at yield, and tensile modulus of 3800 MPa.
How does carbon fibre printing work?
PETG filament is thicker than PLA and therefor need to be printed at a slower speed and high temperature. With that in mind the 3D printing process is almost identical to that of PLA being that they both use FDM printing. The filament is passed through the glass transition temperature and then extruded onto the printing bed layer by layer until were left with you 3D part.
For carbon fibre reinforced PETG, a hardened/steel nozzle is recommended due to the material's abrasive properties. The printing temperature should be around 230-260°C.
