Continuous and chopped carbon fibre reinforcement delivers aerospace-grade strength-to-weight ratios in printed parts. Purpose-built for structural brackets, jigs, fixtures and end-use production components.
Continuous fibre reinforcement transforms the already-strong Onyx nylon matrix into parts that compete with machined aluminium — at a fraction of the lead time and without CNC setup costs.
Continuous carbon fibre reinforcement achieves tensile strengths up to 800 MPa — exceeding 6061 aluminium (310 MPa) and approaching stainless steel. With a fraction of the density, the specific strength (strength/weight) surpasses most metals.
Eliminating CNC setup, fixturing and tooling costs means a single structural bracket can be produced economically in 1–2 days. Design changes are free — simply update the file and reprint.
Continuous fibre rings and isotropic fibre layers can be oriented to match your load path — unlike chopped carbon FDM, where fibres are randomly distributed. Our team will advise on optimal fibre routing for your application.
Carbon fibre for maximum stiffness and strength, Kevlar for impact and blast resistance, HSHT Fibreglass for high-temperature applications, and standard Fibreglass for cost-sensitive structural parts. All in the same platform.
Onyx — the base matrix material — is a carbon-filled nylon with inherent ESD-dissipative properties. Critical for electronics assembly fixtures, avionics tooling and any application where static discharge must be controlled.
Hollow tube sections with continuous fibre winding, internal ribbing for buckling resistance, and topology-optimised lightweight structures — all achievable without the constraints of filament winding or prepreg layup.
Anywhere structural performance, low weight and design freedom must coexist — continuous carbon fibre printing delivers.
All parts are built with Onyx as the matrix material. Reinforcement fibres are co-deposited to your fibre layout specification.
Lead Times: Onyx and Onyx + Carbon Fibre builds ship in 3–5 business days. Kevlar and HSHT Fibreglass reinforcement requires 5–8 business days. Complex fibre path optimisation may require additional engineering review time — contact us to discuss your requirements.

We work with engineers, designers and procurement teams across Australia every day.
"I would highly recommend Pratik at 3D Printing — with his analytical mind he helped re-engineer a component for an electric scooter. The final design was cost effective, strong and an exact fit."
"Can't speak more highly of this Company. They overcame many difficulties through their tenacity and patience. I highly recommend this company for any 3D prototyping, design or development of your idea."
"Great service, quick turnaround — I needed parts scanned, a couple of design changes and printed. All done quickly, efficiently and A+ quality. Definitely recommend the team at 3D Prototyping."
"It was a pleasure dealing with 3D Prototyping. They are professional and their customer service is excellent. I would recommend these guys any time over any other players in this industry."
"This Company is good, efficient and easy to deal with. Their advice and knowledge around materials really helped us get what we needed. Great service provided. We will certainly use this company again."
Upload your CAD file and describe your structural requirements. We'll review your file, advise on fibre routing and provide a detailed quote — usually same business day.
Chopped carbon FDM blends short carbon fragments into a thermoplastic filament — improving stiffness modestly over plain nylon but achieving tensile strengths of only 40–80 MPa. Continuous fibre technology co-deposits full-length carbon fibre strands layer by layer, achieving 800 MPa tensile strength — 10–20x higher. For structural applications, continuous fibre is the only technology that genuinely replaces metal.
Key guidelines: minimum wall thickness of 0.8mm for Onyx, 1.0mm for fibre-reinforced sections. Fibre cannot turn corners tighter than approximately 3mm radius — avoid sharp internal corners in fibre layers. Hollow tube sections with concentric fibre rings are extremely efficient for bending loads. Our team will review your file and suggest fibre routing optimisation before quoting.
Yes, with appropriate tooling. Carbide or diamond-coated cutters are required — standard HSS will dull rapidly. Drilling for inserts is common and effective. Avoid machining through continuous fibre layers wherever possible as this severs the fibre and reduces local strength significantly. We can advise on machining allowances during the design phase.
Onyx and standard fibre-reinforced parts are rated to approximately 65°C continuous service temperature — sufficient for most indoor industrial environments. HSHT Fibreglass reinforcement extends this to 105°C continuous, with short-term capability above 140°C. For applications above 105°C, contact us to discuss HSHT Fibreglass builds or alternative AM processes such as DMLS.
Traditional prepreg/autoclave carbon fibre achieves higher fibre volume fractions (60%+) and near-zero void content, producing superior ultimate performance — but requires tooling, autoclave access and skilled hand layup. Continuous fibre 3D printing has a lower fibre volume fraction (~35%) but requires no tooling, produces parts in 1–5 days, and allows complex internal geometries that are impossible with layup. It bridges the gap between functional FDM prototypes and full prepreg composites.
