Industrial 3D Printing: Why WAAM Is Built for Production

Key notes:

• Certified Production: Industrial 3D printing focuses on heavy-duty applications and certified metallurgy for deployment in offshore structures, naval vessels, energy equipment, and defense systems.

• Unconstrained Scale: Unlike desktop or prototyping options limited to under 300 mm, Wire Arc Additive Manufacturing (WAAM) can print parts up to 6 meters with the M1 System, or scale indefinitely using custom setups.

• High Output Throughput: Sustains high-speed deposition rates between 2 and 8 kg/h, enabling the continuous 24/7 automated fabrication of components weighing over 20 metric tons.

• Strict Quality Controls: Bypasses visual-only checks to implement rigorous Non-Destructive Testing (NDT), including ultrasonic, radiographic, and penetrant testing to meet rigorous DNV, ASME, and Lloyd’s Register codes.

• Diverse Material Range: Supports a wide portfolio of standard commercial welding wire alloys, including steel, stainless, Inconel, bronze, copper, and Aluminium.

What Does Industrial 3D Printing Actually Mean?

Understanding the precise operational differences between prototyping and true industrial 3D printing is critical for corporate production planning.

Prototyping vs. Industrial Additive Manufacturing

Factor	Desktop / Prototyping 3D Printing	Industrial WAAM (MX3D)
Part Size	Under 300 mm	Up to 6 meters with the M1 System. If the print is split into multiple parts or the MX System is used, no major practical size limit is involved, rendering the print fully tailor-made depending on facility size and available installation space.
Materials	Plastics, limited metals	Steel, stainless steel, Inconel, Aluminium, and more.
Deposition Rate	Measured in grams per hour	2–8 kg/h.
Certifications	None typically	DNV, ASME, Lloyd’s Register.
Production Pattern	Batch-based, daytime operation only	24/7 continuous industrial production.
Cost Per Unit	Low setup cost, high unit cost	High setup cost, significantly lower unit cost at volume.
Quality Control	Visual inspection	Non-Destructive Testing (NDT): UT, RT, PT, MT.
Primary Applications	Prototypes, consumer goods	Maritime, defense, energy, and heavy industries.

Industrial 3D Printing vs. Industrial Casting and Forging

WAAM directly replaces traditional casting and forging for several critical supply chain scenarios:

• Producing large-scale, low-volume, or highly complex one-off parts.

• Manufacturing vital components where no existing tooling or molds are available.

• Replacing time-critical spare parts that suffer from severe foundry lead times.

• Engineering high-performance components where maximum design flexibility is required.

What Industrial Quality Actually Means for WAAM

• DNV Certification: Fully compliant with strict offshore and maritime engineering standards.

• ASME Compliance: Metallurgically engineered for demanding pressure equipment and high-stress environments.

• Non-Destructive Testing (NDT): Ultrasonic (UT), Radiographic (RT), and Penetrant Testing (PT) applied rigorously at every production stage.

• Full Traceability: Comprehensive digital logging of wire heat numbers, real-time process parameters, and deposition records.

WAAM: The Industrial Metal 3D Printing Process

How WAAM Works

Wire Arc Additive Manufacturing uses a robust robotic welding arm to deposit metal wire layer by layer, building up large near-net-shape structures. The entire workflow is controlled by purpose-built software (MetalXL) that monitors deposition parameters in real time to ensure absolute structural integrity and dimensional accuracy.

Industrial WAAM 3D Printing Applications

Energy & Oil and Gas

WAAM is utilized to produce heavy pressure vessels, valve bodies, large flanges, and subsea manifolds. Utilizing high-performance duplex and super duplex wire grades, these parts are fully DNV and ASME certified for severe, high-stress environments.

Maritime & Shipbuilding

Shipbuilders utilize WAAM for massive structural components, custom propulsion parts, and on-demand spare parts to drastically reduce vessel downtime. Components are typically printed using marine-grade SS316L and duplex stainless steel grades.

Defense

Industrial printing offers absolute supply chain independence for critical defense components. It enables the rapid, on-demand production of replacement spare parts and large structural elements using advanced alloys and high-strength steels.

Automotive

Accelerates high-performance engineering by manufacturing custom assembly tooling, massive prototype vehicle chassis configurations, and ruggedized structural components for heavy vehicles.

Architecture & Construction

WAAM allows structural engineers to fabricate custom structural steel nodes, complex free-form geometries, and one-off architectural elements directly from digital coordinates. The optimized truss and the Veranda deck stand as landmark examples of what can be achieved with WAAM in civil engineering.

Frequently Asked Questions

What is industrial 3D printing?

Industrial 3D printing is the automated manufacturing of heavy-duty, production-grade components using certified materials. Unlike desktop prototyping, it produces final-use parts for critical sectors like offshore, maritime, and defense, utilizing multi-axis robotics to build dense parts weighing thousands of kilograms.

What is the largest industrial metal 3D printer?

The largest systems utilize robotic wire arc additive manufacturing (WAAM) technology. MX3D utilizes more than 15 industrial robotic arms mounted on linear track networks within its Amsterdam facility, allowing for the continuous fabrication of monolithic metal structures spanning several meters with no physical build chamber limits.

How does industrial metal 3D printing compare to CNC machining?

While CNC machining is a subtractive method that generates severe material waste, WAAM is an additive, near-net-shape process. It drastically lowers raw material acquisition costs, eliminates custom tooling overhead, and provides complex geometric freedom that subtractive machining cannot economically match, particularly for massive parts.

What materials can be used in industrial 3D printing?

Industrial WAAM systems utilize standard commercial welding wires. This includes high-strength carbon steels, structural stainless steels (like 316L), corrosion-resistant duplex and super duplex steels, lightweight Aluminium, and nickel superalloys like Inconel 625 and 718.

What certifications do industrial 3D printed metal parts require?

Critical components require rigorous third-party validation. Depending on the industry sector, parts must comply with DNV standards for maritime/offshore, ASME and PED codes for pressure equipment, Lloyd’s Register for shipbuilding, and fulfill an overarching ISO 9001 quality management framework.

Is industrial metal 3D printing cost-effective?

Yes, particularly for large-scale, low-volume, or highly complex geometries. By bypassing expensive custom molds, cutting raw material scrap, and shortening logistics cycles from months to weeks, industrial 3D printing removes immense capital expenses and limits expensive asset downtime for heavy industries.
