Large-Scale 3D Metal Printing Services

Our proprietary large-scale 3D metal printing technology makes BIG items in LESS time.


Our Industry-Leading Large-Scale 3D Metal Printing Capabilities

Save time, reduce direct and indirect costs, explore more possibilities, and operate more efficiently than traditional manufacturing operations by using our large-scale 3D metal printing technology for your next large tool.

3D printing, also known as additive manufacturing, is a revolutionary technology that holds promise to revolutionize manufacturing as we know it. However, the vast majority of existing technologies are limited in terms of build envelope and production rates, forcing users to forego their use altogether or compromise on size, material waste, and more.

Wire Arc Additive Manufacturing (WAAM)

One type of 3D metal printing, wire arc additive manufacturing (WAAM), also known as Gas Metal Arc Additive Manufacturing (GMAAM), has gained attention in recent years due to its ability to produce large metal components with high accuracy, efficiency, and countless other benefits.

Our proprietary, state-of-the-art WAAM technology presents a strong additive manufacturing solution for a diverse range of large-scale aerospace, defense, and space tools and components.

Commercial Considerations for Large-Scale 3D Metal Printing

Reduce Lead Times

Reduce lead times from months or years to weeks or days, especially compared to traditional processes like bump-forming

Expanded Design Freedom

Reduce weight, mix multiple materials, and incorporate features and geometries that were previously difficult or impossible

Produce Functional Prototypes

Quickly test actual use in real environments

Reduce Inventory Costs

Print on demand and eliminate supply chain bottlenecks

Reduce Manufacturing Operations

Fewer operations. Fewer handoffs.

Reduce Material Waste

Use less material compared to subtractive processes

Pysical Considerations for Large-Scale 3D Metal Printing


We can 3D print a variety of industrial metals, including combinations of materials.


Unlock new possibilities: tools produced using our large-scale 3D metal printing technology are measured in feet or meters, not mere inches.


Tackle part geometries and features that are challenging or impossible for traditional processes like casting, machining, and bump-forming.

Not Your Typical Robotic Programming

CAD-to-Path Planning

With large-format wire-based metal additive manufacturing, the component is manipulated while depositing material. Advanced software is critical to address complex path-planning and coordinated motion between the robot and the positioner.

Large-scale 3D metal printing path planning

Full control over each layer’s wire path allows for optimal process parameters and material deposition.

Maintaining Optimal Layer Height and Part Dimensions

We have developed height-sensing and adaptive feedback software to maintain tight customer-specified tolerances.

Complex Parts

Complex tool printing can be achieved using advanced robots collaborating with rotating positioners and motion-control software.

Large-Scale 3D Metal Printing Applications in Aerospace, Defense, and Space

While it is one of the oldest 3D printing technologies, WAAM is relatively new in terms of commercialization and has not yet been certified or qualified for flight hardware applications. Thus, its aerospace, defense, and space applications have so far been limited to tooling. Learn more about its applications in other industries here.

WAAM presents a variety of strong benefits when used for tooling applications in aerospace, defense, and space manufacturing, especially for layup molds, trim fixtures, and other tooling used in composite part fabrication.

3D-Printed Tooling for Aerospace, Defense, and Space Manufacturing

New tooling is often a bottleneck in getting new manufacturing operations up and running on time, particularly as engineers often need to accommodate last-minute design changes. Additive manufacturing can eliminate the tooling bottleneck by providing design flexibility, adaptability to changes, shortened lead times, and cost savings.
