Jabil PA 4535 CF is among the strongest PA co-polymer carbon fiber filaments available on the market, delivering increased strength and stiffness. PA 4535 CF has a 35% carbon fiber loading, providing improvements in tensile strength, impact strength, Z strength and elongation at break, with the added benefit of being ESD safe.
Due to its excellent mechanical properties, it is ideal for parts that require stiffness and strength. Common use cases include aluminum replacement parts, housings that require tight tolerances, jigs fixtures and tooling, clips, brackets, retainers and covers. This material candidate is ideal for aerospace, automotive and general manufacturuing.
Printing Difficulty: Intermediate
Jabil PA 4535 CF can be purchased from AON3D directly by contacting help@aon3d.com.
Jabil PA 4535 CF is highly hygroscopic and will quickly absorb and retain moisture from the atmosphere. This will affect the visual quality and mechanical properties of printed parts. Oozing with a rough and less matte surface finish may occur if it has been hydrated.
Dry filament at 75ºC for 6-12 hours in a convection oven. Please ensure drying equipment respects our site requirements to ensure adequate drying performance is achieved.
Store filament in air tight bags or containers alongside silica or zeolite desiccant. Make sure to replace desiccant regularly as its moisture capture ability is exhausted.
Our Filament Dry Storage and Feed System setup prevents filament moisture uptake minimizing the impact of moisture on the printing process, contact help@aon3d.com for more information.

Jabil PA 4535 CF prints very well on Garolite G-10 sheets. Wipe down the Garolite build sheet with isopropanol before use.
Bed temperature is typically set to 100°C for this build sheet. The Garolite G-10 sheet is sensitive to Z offset calibration and thermal stability of the printer system. For best results, ensure that the machine has reached thermal equilibrium before calibrating.
Jabil PA 4535 CF prints well on the PEI build sheet with the use of a wide brim and Nano Polymer Adhesive, an applied adhesion aid. Wipe down the PEI build sheet with isopropanol before use.
Bed temperature is typically set to 100°C for this build sheet. The PEI build sheet is sensitive to Z-offset calibration. Ensure that the machine has reached thermal equilibrium before calibrating. If the bed-to-nozzle distance is too close, excessive material accumulation on the PEI build sheet may occur.
Jabil PA 4535 CF prints well on the CF-PEEK composite plate with the use of Nano Polymer Adhesive, an applied adhesion aid. The Nano Polymer Adhesive may improve adhesion first layer adhesion for bed temperatures up to 100ºC.
For best results, process settings should be adjusted based on a particular model geometry. If you require process development support, our Applications Engineering team can help! Send us a message at help@aon3d.com to consult with one of our Additive Manufacturing Specialists.
Optimal extrusions are visually black with a rough texture. For optimum printability, a 0.6mm nozzle is recommended for Jabil PA 4535 CF. It can be printed at the same speeds as unreinforced plastics (30-80 mm/s) while achieving better strength and stiffness due to the high carbon fiber reinforcement.
Small, low-mass, and larger parts can be printed at moderate extrusion temperatures without much difficulty as the degree of crystallization-induced shrinkage is low. Part warping and deformation are generally not an issue due to the 35% carbon fiber reinforcement. However, avoid very high extrusion temperatures as it may induce enough polymer shrinkage from crystallization to cause part warping.

Jabil PA 4535 CF filament is highly abrasive. The use of wear-resistant extruder gears and nozzles is necessary to successfully and reliably print this material. AON3D recommends using an Extruder Pro and a tungsten carbide nozzle to improve surface finish and reduce component wear. Contact the Customer Success team at help@aon3d.com to order the assembly.
For general information, see the Using Supports and Support Materials and Dual Extrusion page.
Adding a wipe in the Tool Change Script will clean the tool head as it oozes and purges between each layer. If printing at elevated temperatures, the extrusion temperature of Jabil PA 4535 CF can be decreased during idle to 240ºC if needed. This is not usually necessary as PA 4535 CF is resilient enough to not degrade within its processing temperatures for moderate periods.
Increasing the Retraction Distance and Extra Restart Distance in Tool Change Retraction may mitigate the loss of material and pressure that may cause under extrusion at the beginning of each layer. If the geometry permits, printing inside-out may be an option to hide the under-extruded seam without drastically modifying the Tool Change Retraction settings.
Aquasys® 120 is a compatible soluble support material for PA 4535 CF.
To ensure build platform compatibility between PA 4535 CF and AquaSys® 120, we recommend using the Garolite G-10 sheet for optimum first layer adhesion. Dual tool printing with PA 4535 CF and AquaSys® 120 requires fine-tuning for optimal printing.
For more information about printing with this support material, see the AquaSys® 120 guide.
All AON3D-validated materials are available in the SuperSlicer configuration bundle. Refer to SuperSlicer Installation and Update to install and update the SuperSlicer software.

Allow all machine components to reach room temperature before proceeding further. Failure to allow components to cool down will result in thermal injury (burns) to personnel.
Shrinkage, deformation, and warpage due to thermal shock may occur from removing the part before letting the machine cool. Instructions for removing the part from the build platform and removing support material can be found on the Build Platform Adhesion and Using Supports and Support Materials guides.
Jabil PA 4535 CF parts can be peeled off the build surfaces by hand at room temperature. If needed, a spatula can facilitate part removal.

Clogging may occur frequently when using a 0.4mm nozzle or lower due to the large carbon fibers in the filament. We recommend opting for at least a 0.6mm nozzle to print Jabil PA 4535 CF. Clogging may occur during your first layer if the nozzle is too close to the bed. If it occurs, make sure to redo your Z calibration, and change the offset if necessary.
It has been observed that the high fiber loading of the material results in increased friction in the PTFE tubing that feeds the filament to the extruder. As a result, extrusions and jams may occur if the filament is above tolerance. This issue can be mitigated by straightening the PTFE tubing between the spool and the extruder motor and maximizing the bend radius at the back of the printer.
The high fiber loading content in Jabil PA 4535 CF can result in wear on both the nozzle and extruder gearset component. Significant wear in the nozzle will result in intermittent and uncontrolled extrusion. Significant wear in the gearset would result in an inability for the extruder to push filament through the nozzle. It is recommended to schedule regular inspections of the gearset to monitor and expect to replace the gearset at a higher frequency compared to printing with a neat polymer.
AON3D recommends using an Extruder Pro and a tungsten carbide nozzle to improve surface finish and reduce component wear. Contact the Customer Success team at help@aon3d.com to order the assembly.
Overly hydrated filament may produce an undesired roughness to the surface and mechanically weaker components. Follow the drying procedure in the above Moisture Control section.
