The first 3D printed ISO certified marine gangway image

Caracol’s LFAM technology is driving innovation in the marine industry with Heron AM. This turnkey large-format thermoplastic composite 3D printing platform was selected by Namthaja to develop a new application for Jana Marine Service Company, ensuring high precision, speed, and process repeatability.

Production with Heron AM and ASA GF

The project, developed by Namthaja – Saudi Arabia’s leading 3D printing service bureau – resulted in the production of the first 3D printed marine gangway for Jana Marine Service Company LLC.

Starting from design and engineering, the team developed a 3-meter-long gangway designed to withstand heavy loads during crew embarking and disembarking operations. The component was manufactured as a single piece using Heron AM and ASA reinforced with glass fiber, in compliance with ISO 7061:2015 standards.

Production and performance data:

  • Technology: LFAM (Heron AM)
  • Material: ASA Glass Fiber (ASA GF)
  • Part Length: 3 meters
  • Standards: ISO 7061:2015
  • Tested Load: Over 720 kg
  • Required Deflection: 40 mm
  • Achieved Deflection: < 20 mm at 750 kg

The part was produced in a single print, eliminating the need for assembly and manual operations. The material ensures UV and weather resistance, making it suitable for outdoor marine environments while meeting the required mechanical performance.

Benefits and industrial value

The adoption of Caracol’s LFAM technology delivered significant advantages in terms of efficiency, performance, and scalability:

  • Reduced costs and lead times: Streamlined production with no assembly or manual processes required
  • 30% weight reduction: Lighter structure compared to traditional gangways without compromising strength
  • High mechanical performance: Enabled by advanced composite materials such as ASA GF
  • Environmental resistance: Excellent durability in outdoor conditions, including UV and weather exposure
  • Industrial scalability: Certified process ensuring repeatability and reliable large-scale production

This project demonstrates how large-format additive manufacturing with composite materials can transform marine production, enabling lighter, more efficient, and fully industrialized components.
