Combining 3D technology and port operations This is completely changing the daily work of port technicians. Where before they relied on measuring tapes, improvised sketches, and a lot of "eyeballing" experience, now 3D scanners, drones, digital twins, LiDAR, and other technologies are coming into play. Print 3D capable of reproducing a gantry crane, a dock, or a propeller with millimeter precision. This not only improves safety but also reduces costs, downtime, and dependence on external suppliers.
This new technological landscape is not limited to the world's leading ports; it is also beginning to be seen in smaller port facilities, logistics sectors and experimental projects These projects blend circular economy, digitalization, and automation. From reusing marine plastics to manufacture 3D-printed parts, to LiDAR surveillance systems at harbor entrances, and from rapid manufacturing of submarine spare parts to custom metal keels, the range of applications grows every year.
3D technology in the daily work of the port technician
The current port technician has digital tools for 3D scanning and modeling which allow him to inspect metal structures, cranes, piles and docks without stopping operations. A scanner like Artec LeoCombined with dimensional control software like Geomagic Control, it makes it possible to capture the actual geometry of a corroded structure and compare it with the original design to detect deformations almost invisible to the human eye.
Thanks to these models, it is feasible plan maintenance predictivelyPrioritizing which components need replacing before they fail and cause a serious incident or unplanned downtime. A gantry crane can be fully digitized, analyzing stresses and detecting misalignments, reducing the risk of accidents and saving a significant amount of money on emergency repairs.
In parallel, the use of virtual or mixed reality glasses allows the technician to "enter" the 3D model of the infrastructure and visualize, in real time, load data, container movements, or fatigue states of certain components. It is a much more intuitive way of interpreting the information than classic tables and static plans.
The old scene of the boss holding the tape measure while the technician takes crooked notes on a piece of paper is becoming a thing of the past. Today, with a drone equipped with camera and 3D scannerIt is possible to detect a crack in a dock edge while performing a quick and safe visual inspection, without climbing into dangerous areas or interrupting loading and unloading activity.
These tools not only provide accuracy; they also change the way we work. The technician is freed from many repetitive tasks and manual measurements, and can focus on analyze data, prioritize actions, and propose technical improvements supported by reliable models.
Maneuvering simulation and digital twins in a port environment
3D technology has also made its way into the way complex maneuvers and operations are rehearsed before being deployed on the dock. With tools such as Autodesk Revit or SolidWorks It is possible to model port components, structures and equipment, and then integrate them into virtual environments where loads, displacements and stresses are simulated.
This approach is reinforced by the creation of digital twins With platforms like Unity Reflect, it's possible to recreate a container terminal, a docking area, or a storage park. Within this virtual environment, crane maneuvers, truck and ship traffic, and the placement of new infrastructure can be simulated without any risk to people or equipment.
For the port technician and the operators, this means they can Test operational configurations, validate security procedures and train new recruits without interrupting regular operations. Delicate or infrequent maneuvers become trainable routines in a controlled environment.
By combining data from 3D scanners, sensors in machinery, and port management systems, digital twins become a visual command center where the state of the infrastructure is monitored and "what if" scenarios are simulated with high reliability.
Thus, 3D simulation ends up having a direct impact on Fewer unexpected downtime, improved workplace safety, and greater efficiency in the use of cranes, docks and port warehouses.
3D printing and digital manufacturing for ports and the maritime sector
3D printing has gone from being a laboratory curiosity to becoming a a real tool for maintenance, repair and customization in industrial and maritime environments. In the port and naval sector, this translates into the ability to produce, in a matter of hours, spare parts, tools and components adapted to very specific needs.
In sectors where every minute of operation counts, such as port logistics, having on-site digital manufacturing It's key. Many operations previously relied on distant suppliers, lead times of weeks, and inflexible traditional manufacturing processes. With 3D printing, it's possible to accelerate validations, perform rapid fit testing, and have functional parts without shutting down critical facilities.
The value lies not only in printing a part, but in drastically reducing development times. Technical teams can design, iterate, and improve solutions almost in real time, adapting quickly to new operational requirements, changes in regulations or unforeseen problems in loading and unloading equipment.
Companies like EVOT and Navantia They have begun to use these technologies for the development of prototypes, special supports, adapters and functional components In Colombia and other emerging markets, this demonstrates that innovation no longer depends solely on large industrial centers. New laboratories and makerspaces can become strategic allies of ports and maritime operators.
In the international maritime environment, additive manufacturing is covering everything from submarine parts and large propellers from custom aluminum keels and underwater scooter bodies to injection nozzles for more efficient and environmentally friendly cargo engines.
Advanced applications of 3D printing in the maritime-port industry
One of the star applications of 3D printing in the maritime sector is the manufacturing spare parts for ships and submarinesThe U.S. Navy, for example, has clearly seen that additive manufacturing helps alleviate pressure on its supply chain, combining traditional suppliers with 3D printing companies to produce components for Columbia-class ballistic missile submarines.
In this context, technology focuses on parts that previously required casting, forging, or complex machining3D printing shortens production times and provides flexibility to introduce geometric improvements that would be impossible with traditional methods.
Another striking use case is electronic additive manufacturing (EBAM) applied to the mapping of the seabedThe Canadian company International Submarine Engineering is using this technology to produce a titanium variable ballast tank for an autonomous underwater vehicle that will explore the Arctic. With 3D printing, manufacturing time was reduced from 16 to 8 weeks, resulting in significant cost savings.
3D printing is also extending to more experimental solutions, such as printed chainmail Initially designed by NASA for space use, this material could also be applied to ships. Capable of reflecting and absorbing heat depending on the exposed surface, it would serve as thermal and structural protection for hulls subjected to extreme conditions.
In the field of underwater inspection and maintenance, the Norwegian company Kongsberg Ferrotech is betting on advanced robotics combined with additive manufacturing to repair underwater pipelines, offshore wind turbines and electrical cables more efficiently, ensuring savings of between 30 and 50% in intervention costs.
Singapore, through its Maritime and Port Authority (MPA), is promoting a specific project to maximize the safe operating time of the vessels through 3D printing of spare parts. The Wilhelmsen consortium, together with Kawasaki Heavy Industries, Wärtsilä, Hamworthy Pumps and DNV GL, is working on a production network near the port that shortens lead times and guarantees immediate availability of critical parts.
Certifications, materials and large naval components printed in 3D
For 3D printing to become established in the maritime sector, it is essential to have specific safety standards and certificationsThe Norwegian classification society DNV has taken the lead in this field, verifying processes, materials and equipment used to manufacture ship components that must meet very strict criteria.
An example of this is the certification awarded to a ship's propeller two meters in diameter Produced using additive manufacturing by SY Metal in South Korea. This verification demonstrates that the mechanical properties and performance of the part are equivalent to, or even better than, those of a conventionally manufactured propeller.
DNV also evaluates and standardizes various additive manufacturing processes, such as WAAM (Wire Arc Additive Manufacturing), powder bed fusion (PBF), and blown powder technologies (BPT), ensuring that their application in ships and marine structures is reliable and repeatable over time.
In Europe, the company MX3D has partnered with KM Yachtbuilders to design a 3D printed aluminum keel using WAAM. The fully customized part demonstrates the potential of this technology to adapt to unique designs, overcome the shortage of skilled welders, and open the door to more flexible production of naval components.
In turn, ThyssenKrupp, with the technological support of EOS, became the first company in the world to receive DNV GL certification for 3D-printed metal parts intended for the maritime sector. This approval equates the quality of printed components with that of traditional parts, positioning additive manufacturing as a fully valid option for submarines and next-generation ships.
Other collaborations, such as that of 3D Systems with Huntington Ingalls Industries' Newport News Shipbuilding division, focus on the development of specific metal alloys for marine applicationssuch as copper-nickel (CuNi) and nickel-copper (NiCu). These corrosion-resistant alloys allow for the creation of cast valves, housings, supports, and spare parts with up to a 75% reduction in supply chain lead times.
The use of 3D printing also extends to the design of more energy-efficient components. One example is the 3D-printed fuel injection nozzle developed at the Technical University of Denmark, whose curved geometry It improves fuel flow and combustion.contributing to greener and more fuel-efficient cargo ships.
Circular economy and recycling of marine plastics with 3D printing
Beyond operational efficiency, 3D technology is being used to tackle a major environmental problem: ocean plastic wasteEach year, more than 12 tons of plastic waste accumulate in ports, shores and seabeds, originating from both land and sea activities.
The European project CircularSeas focuses precisely on transforming this waste into raw material for 3D printingApplying circular economy principles, the idea is that the maritime and port industries themselves will collect, process, and reuse the plastic they generate, converting it into filament or granules to manufacture products, components, and parts that can be reused in the sector.
The challenge is twofold: on the one hand, to demonstrate that 3D printing can contribute real benefits to an area where manufacturing and prototyping were not the core of the businessOn the other hand, design a flexible printing environment capable of working with non-standard recycled plastics, with variable properties depending on the waste of origin.
To achieve this, CircularSeas proposes a 3D printing framework hardware-independent, user-oriented, and adaptable to different grades of recycled plastic derived from marine waste. This makes it easier for port companies, shipping companies, and logistics operators to integrate the technology without having to become experts in materials or process engineering.
This approach demonstrates that 3D technology not only helps to manufacture faster, but also to reduce the environmental impact of port activitycreating a virtuous circle where waste is transformed into useful resources for the industry itself.
LiDAR and 3D models for access control and security ISPS
Another clear application of 3D technology in the port sector is based on the use of LiDAR (Light Detection and Ranging) for monitoring and environmental modeling. These devices emit laser pulses that, when reflected off objects, allow for the calculation of distances and the generation of highly accurate three-dimensional models.
The project “ISPS Security Control in Bocana using LiDAR technology” proposes installing LiDAR devices in each side of the port entrance, in order to monitor maritime traffic, detect intrusions or anomalies and reinforce compliance with the International Ship and Port Facility Security (ISPS) Code.
For years, the high cost of these devices, coupled with the price of associated software and other system components, hindered their adoption in many ports. However, the arrival of more affordable models manufactured in ChinaWith longer duration and ranges of up to 500 meters, it has greatly expanded its deployment possibilities.
These systems allow for highly reliable detection. vessels, floating objects or obstacles in sensitive areaseven in low visibility conditions, supporting both safety and port traffic management.
The same technology is being extended to the port-linked rail mode, as LiDAR sensors can Monitor the condition of the overhead contact line, identify obstacles on the track and improve safety in intermodal logistics operations within the port environment.
Drones, 3D mapping and modernization of the nautical port sector
Drones have become a natural ally of 3D technology applied to ports. Equipped with high-resolution cameras and multispectral sensors, they are capable of collect data to generate 3D models of the terrain and infrastructureas well as strengthening security and operational control.
In terms of surveillance, drones allow monitoring large maritime and terrestrial areas They are used to detect suspicious activity, smuggling, unauthorized fishing, or undeclared operations. Their ability to fly in complex weather conditions makes them a key tool in critical missions.
For inspection and maintenance, drones can get close to hard-to-reach areas on cranes, docks, and elevated structuresCapturing detailed images helps identify corrosion, cracks, or deformations without the need for climbing or scaffolding. This improves safety and saves intervention time.
In coastal mapping and cartography, these unmanned aerial vehicles generate orthophotos and point clouds that are transformed into 3D models of the coastline. This data is essential for planning port expansions, assessing damage after storms, or designing dredging projects with a precise knowledge of the terrain.
Companies like DJI, Skydio, and Parrot are leading the development of drones specifically designed for the maritime and port environment, with constant improvements in autonomy, resistance to saline environments and integration capabilities with data management platforms.
In Spain, some ports, such as those in the Balearic Islands, have already incorporated drones for surveillance, inspection and management tasksShowing real-world examples of how these technologies reduce costs, improve security, and provide high-value information for decision-making.
Challenges and opportunities: regulation, training and the future of the smart port
The massive deployment of 3D technologies, drones, and automation systems in ports is not without its challenges. One of the most significant is the regulatory frameworkespecially with regard to the use of drones in controlled airspace, the processing of sensitive data, and the cybersecurity of connected systems.
Technical limitations also appear, such as the drone battery life, sensor robustness in saline environments and the need for equipment resistant to extreme weather conditions. Constant innovation is required to overcome these barriers.
In parallel, the training of professionals becomes crucial. Institutions like UMILES University offer professional drone pilot courses adjusted to the requirements of the AESA, preparing operators capable of working safely and in accordance with current regulations.
Looking ahead, ports are expected to become increasingly integrated drones with artificial intelligence, advanced sensors, and data analysis platformsbecoming true smart ports where decisions are supported by real-time information and predictive models.
As these technologies become more established and cheaper, more ports of varying sizes will be able to adopt them, reducing the gap between major logistics hubs and regional terminals. The key will be in combine technological investment, staff training and collaboration between port authorities, technology companies and research centers.
This entire ecosystem of 3D scanning, digital twins, additive manufacturing, LiDAR, and drones is redefining the role of port technicians and the infrastructure itself. We are moving from an environment heavily reliant on manual expertise and rigid processes to a scenario where Flexibility, the ability to manufacture and validate quickly, sustainability, and safety They set the standard, opening the door to more efficient, resilient ports aligned with the environmental and logistical demands of global trade.
