When to use this service
3.5.1- Structural parts replacing metal components
- Weight reduction without losing strength (aerospace, drones)
- High thermal resistance (under hood, around hot systems)
- Defense, aerospace and motorsport environments
- Localized reinforcement in a specific load zone
- Printed parts needing stiffness beyond the base material
How the process works
3.5.2Load analysis & planning
Identifying force directions, choosing external / internal / localized layup, selecting fiber type (carbon / fiberglass) and number of plies.
Surface preparation
Sanding, cleaning and surface treatment of the printed or machined part to maximize resin bond.
Layup
Placing fiber plies along the load directions, impregnating with epoxy resin and removing air bubbles under vacuum.
Cure & post-cure
Controlled temperature and humidity cure, plus a post-cure bake for maximum strength and stiffness.
Finishing
Edge trimming, polishing, optional UV coating, paint finish or exposed carbon weave.
Inspection & documentation
Visual and dimensional inspection, plus per-batch documentation - important for defense, medical and aerospace clients.
Materials & technologies
3.5.3Example project
3.5.4Aerospace drone arm - 40% lighter
Structural arm for an aerospace drone platform: the CNC-machined aluminum version was replaced by an MJF part with external 3-ply carbon fiber reinforcement. Weight dropped 40%, static strength was maintained and lead time fell from two weeks to two days. Passed aerospace load testing and 120°C thermal endurance.
Frequently asked
3.5.5Carbon or fiberglass - how do I choose?
Carbon gives maximum strength and stiffness at minimum weight - aerospace and motorsport. Fiberglass is much cheaper, more flexible and more impact-tolerant - enclosures, industrial gear and anything that doesn't need the extreme end of carbon.
How much does strength improve?
2–3× over a pure printed part, depending on fiber type, orientation and ply count. Thermal resistance also increases significantly.
Can you reinforce only a specific area?
Yes - localized reinforcement is a common scenario. We identify the load zone and apply plies only there, which saves weight and cost.
Is the reinforcement waterproof and UV-stable?
Yes, after full cure and post-cure. For especially aggressive environments we add a UV-stable clear coat or industrial paint to protect the resin surface.
