Carbon Fiber Parts with
3D Printed Molds & Patterns
Replace high-cost CNC milling with agile, cost-saving solutions for low volume production
You can't wait to find out, how you could use 3D printed carbon fiber molds and patterns in your production?
SAVE TIME
Drastically reduce lead times and speed up design iterations
5x CHEAPER
3D printing molds costs a fraction of the price of CNC milling aluminum
AGILE ITERATION
Adapt, test, and produce parts in-house with ease
Large-scale patterns and carbon fiber molds are expensive, slow to produce, and complex shapes may not be feasible. Typical CNC milling of patterns wastes material and design iterations are expensive and time-consuming. Therefore, 3D printing can play a huge role in producing high-quality carbon fiber parts while reducing costs and lead times. BigRep machines deliver cost-saving solutions to produce large-scale carbon fiber molds.
How to Mold Carbon Fiber with Additive Manufacturing
Airflight uses prepreg carbon fiber parts to build their human-sized drones. See how they use BigRep machines to produce 3D printed molds for faster, cheaper carbon fiber fabrication
Two Methods of 3D Printing for Carbon Fiber Molding
Method 1:
3D Print the Carbon Fiber Mold
If the part design still needs iterations, the part is intended for small batch production, or the carbon fiber prepreg requires lower temperature / pressure resistance, then 3D printing the mold is recommended.
The mold is 3D-printed and post-processed to required surface quality. If needed, the mold can be designed with inlets to pour in reinforcement filler so the mold can withstand pressure in the autoclave. Carbon fiber prepreg is laid into the mold, placed in a vacuum bag, and cured in an autoclave at the required temperature and pressure settings.
Step 1
3D Print the mold
Step 2
Post-process the mold
Step 3
Use mold to create CF part
Step 4
Post-process the CF part

Method 2:
3D Print the Pattern
If the part design is finalized, the part is intended for series production, or the carbon fiber prepreg requires higher temperature / pressure resistance, then 3D printing the pattern is recommended.
The pattern is 3D-printed and post-processed to required surface quality. Then a carbon fiber mold is produced from the pattern, typically using glass fiber or high temperature epoxy molding paste. Carbon fiber prepreg is laid into the mold, placed in a vacuum bag, and cured in an autoclave at the required temperature and pressure settings.
Step 1
3D Print the pattern
Step 2
Post-process the pattern
Step 3
Create mold from pattern
Step 4
Use mold to create CF part
Step 5
Post-process the CF part

"BigRep allowed us to iterate large-scale carbon fiber parts
5x times cheaper than with standard CNC milling.
With one machine we can produce prototypes, molds, jigs, and fixtures."
Mikkel Kærsgaard Sørensen, Technical Director and Co-Founder of Airflight
"Previously we needed expensive mold tooling to see the design in real life.
Our Bigrep printer has transformed how
we develop and paid for itself many times over."
Andrew Slorance, CEO of Phoenix Instinct
