Step 1 – Prototype Testing & Design Validation (R&D Phase):<\/strong> Print prototypes to verify fit and form before the design is finalized, catching issues early before tooling or production commitments are made.<\/p>\n<\/li>\n Step 2 – Jigs & Fixtures (Production Preparation):<\/strong> Once manufacturing begins, produce custom assembly aids on demand to guide and accelerate machine construction on the shop floor.<\/p>\n<\/li>\n Step 3 – End-Use Machine Components (Core Manufacturing):<\/strong> Print low-volume brackets, housings, and selected machine internals without minimum order quantities, integrated directly into the equipment you build.<\/p>\n<\/li>\n Step 4 – End-of-Arm Tooling & Grippers (Automation Integration):<\/strong> After the machine is built, customize lightweight grippers and EOAT for robotic handling and automation cells, enabling flexible, application-specific integration.<\/p>\n<\/li>\n Step 5 – On-Demand Spare Parts (Aftermarket & Maintenance):<\/strong> Once equipment is in the field, maintain a digital parts library to print legacy replacement parts on demand, eliminating long lead times and costly downtime for your customers.<\/p>\n<\/li>\n<\/ul>\n For large or complex equipment, physical prototypes are essential for reviewing ergonomics and internal layouts that CAD alone may not fully capture. This proactive approach accelerates iteration cycles and significantly reduces the risk of costly design errors during the late stages of development.<\/p>\n Examples: <\/strong>equipment housings, enclosure panels, airflow ducts, full-scale mockups, and assembly-validation models.<\/p>\n Case 1: Airbus: Prototype Iteration for Aircraft Interior Components<\/strong><\/p>\n Airbus<\/a> uses 3D printing to prototype aircraft interior components such as panels, linings, and covers in full scale. Previously, each design iteration required outsourcing CNC machining to create molds, which is a process that took weeks per cycle.<\/p>\n With 3D printing, engineers can print a part, evaluate it, redesign it, and repeat the cycle in-house until the design is finalized, significantly compressing development time.<\/p>\n Case 2: Siemens Energy: Rapid Prototyping and Proof-of-Concepts<\/strong><\/p>\n At its Orlando Innovation Campus, Siemens Energy<\/a> uses 3D printing for rapid prototyping, proof-of-concepts, and custom engineering solutions. The goal is straightforward: help teams validate ideas and test designs earlier in development, before committing to more costly processes.<\/p>\n Efficient machine construction depends on specialized tools for assembly, positioning, and inspection. Because these aids are highly task-specific, 3D printing offers a faster and more ergonomic alternative to traditional machining.<\/p>\n This agility is particularly valuable for teams managing custom equipment builds or frequent production-line updates, where tools must be revised quickly to match evolving workflows.<\/p>\n Examples: <\/strong>assembly fixtures, positioning jigs, inspection tooling, and drill-protection templates.<\/p>\n Case 1: Airbus Crisa: 3D Printing Lab for Manufacturing Tooling<\/strong><\/p>\n Airbus Crisa<\/a> offers one of the clearest official examples of this workflow. Its internal Mechanical Printing Lab produces shop-floor tooling for manufacturing, covering handling, testing, and setup applications. These are practical tools that improve day-to-day operations without waiting on conventional tooling lead times.<\/p>\n Case 2: Alstom: Machine Tools and Jigs for Rail Manufacturing<\/strong><\/p>\n In rail manufacturing, Alstom<\/a> reported in 2023 that it uses 3D printing to produce machine tools and jigs, including a jig designed to ease screwing holes in carbody shells in Germany. This shows additive manufacturing being used directly on the production floor to support assembly efficiency, not just early-stage prototyping.<\/p>\n For end-use components, the focus shifts from simple printability to long-term operational reliability. 3D printing is most effective for low-volume, custom parts where complex geometries or part consolidation offer a clear advantage over expensive conventional tooling.<\/p>\n While ideal for brackets and housings, components with high cyclic loads or strict regulatory requirements still require rigorous validation before deployment.<\/p>\n Examples: <\/strong>brackets, sensor mounts, protective covers, small housings, and machine internals such as manifolds.<\/p>\n Case 1: Bosch Rexroth: Additively Manufactured Manifolds for Recycling Systems<\/strong><\/p>\n Bosch Rexroth<\/a> provides a strong end-use component example with custom hydraulic manifolds produced for recycling systems in 2022.<\/p>\n The company highlights benefits such as lower weight (approximately 30% reduction), better flow characteristics through optimized internal geometry, and easier machine integration due to a more compact design.<\/p>\n The key point is that the printed part is a real machine component installed on operating equipment rather than a temporary prototype, which delivers measurable savings in energy and CO\u2082 emissions throughout its operational lifespan.<\/p>\n Case 2: ABB: 3D-Printed Paint Manifolds for Industrial Robots<\/strong><\/p>\n ABB<\/a> used metal 3D printing to redesign the paint manifold on its industrial paint robots, a component traditionally machined from solid stainless steel using CNC, resulting in high material waste and long delivery times.<\/p>\n By switching to additive manufacturing, ABB reduced the weight of the manifold by 43% while preserving full functionality and structural stiffness, with the optimized geometry also improving ease of assembly and cleaning.<\/p>\n As a critical component integrated into the automated systems you deliver, End-of-Arm Tooling (EOAT) directly impacts the equipment’s payload and cycle time.<\/p>\n 3D printing allows engineering teams to move beyond off-the-shelf limitations by creating task-specific grippers and vacuum tools that are optimized for the end-user’s unique production requirements.<\/p>\n Examples: <\/strong>robotic grippers, vacuum suction plates, gripper fingers, and tool bodies tailored to specific motion paths.<\/p>\n Case 1: BMW Group: 3D-Printed Robot Grippers for Production Lines<\/strong><\/p>\n In 2024, the BMW<\/a> Group reported using 3D-printed robot grippers across its production facilities, including a large gripper element for handling carbon fiber reinforced polymer (CFRP) roofs at its Landshut plant.<\/p>\n The gripper, weighing around 120 kilograms, can be manufactured in just 22 hours and is approximately 20% lighter than a conventional equivalent, reducing wear on the robot and extending its operating life.<\/p>\n Case 2: Schmalz and Lang Metallwarenproduktion: Lightweight Gripper for Sheet-Metal Parts<\/strong><\/p>\n Schmalz<\/a> documents a custom lightweight gripper (SLG) designed for Lang Metallwarenproduktion to handle thin-walled stamped and bent parts with complex geometry.<\/p>\n The gripper was additively manufactured and assembled within a few days based on the STL file of the target part, resulting in a 140 percent increase in productivity.<\/p>\n The case ties 3D-printed EOAT directly to measurable handling performance, which is exactly why automation teams adopt custom additive tooling.<\/p>\n 3D printing enables a “print-on-demand” model that solves the availability issues of legacy and low-frequency spare parts.<\/p>\n By transitioning from physical to digital inventory, manufacturers can produce replacement components locally and only when needed, significantly reducing lead times and storage costs.<\/p>\n Examples:<\/strong> obsolete brackets, covers, connectors, and specialized packaging-machine change parts.<\/p>\n Case 1: Deutsche Bahn: On-Demand Spare Parts for Railway Maintenance<\/strong><\/p>\n1.
