For many makers, 3D printing means creating prototypes, replacement parts, or custom projects in the workshop. But inside the automotive industry, additive manufacturing has evolved far beyond concept models. I stopped by the Stratasys to talk with Fadi Abro about how automotive manufacturers are using industrial 3D printing to accelerate development, improve manufacturing, and even produce end-use components.
One of the biggest takeaways from the conversation was that automotive companies typically use 3D printing in three major areas: prototyping, manufacturing tooling, and production parts.
Prototypes That Look Like Finished Products
The first application is product development. Before a vehicle ever reaches production, manufacturers need realistic prototypes that engineers, designers, and focus groups can evaluate.
Stratasys uses its PolyJet technology to create prototypes with an impressive level of realism. Instead of simply producing a rough plastic model, these parts can include multiple colors, textures, varying material hardness, and extremely fine detail directly from the printer.
During the interview, Fadi demonstrated parts that featured realistic wood grain, buttons, textured surfaces, and flexible materials that closely resemble injection-molded components. While these prototypes aren’t intended to replace final production parts, they provide engineers with functional, high-fidelity models that closely mimic the appearance and feel of the finished product.
Because PolyJet can blend multiple UV-curable resins at the voxel level, manufacturers can create parts with different colors, textures, and durometers in a single print, significantly reducing the amount of manual finishing traditionally required.
Building the Factory Before Building the Car
While prototypes often receive the most attention, Fadi explained that one of the biggest uses of industrial 3D printing is actually manufacturing tooling.
Every automotive assembly line relies on fixtures, jigs, alignment tools, gauges, and custom manufacturing aids. Even small improvements to these tools can have a significant impact on production efficiency.
“If you’re Ford and you’re getting one car out every minute, if you can get 10 more cars out a day, that is much more impactful,” Fadi explained.
Instead of machining these tools from metal, many manufacturers now produce them using industrial FDM printers and engineering-grade thermoplastics. Materials such as carbon-fiber-reinforced nylon provide the strength, durability, and heat resistance required for factory environments while dramatically reducing lead times.
One example on display was a large Subaru assembly fixture that assists with vehicle alignment during production. Creating tools of this size on hobby-level equipment simply isn’t practical, which is where industrial build volumes become essential.
Large Industrial FDM Systems
One of the systems featured during the booth tour offered a build volume of approximately one meter by 600 mm by 600 mm, or roughly 39 x 24 x 24 inches.
Beyond its size, one of the machine’s biggest advantages is its heated build chamber.
Maintaining a consistent chamber temperature allows printed layers to cool and shrink evenly throughout the build. This greatly improves layer adhesion while reducing internal stresses that could otherwise cause warping or delamination, particularly when printing high-performance engineering materials.
According to Fadi, Stratasys continues expanding its material portfolio, offering everything from ABS to high-temperature materials such as ULTEM for demanding industrial and aerospace applications.
When 3D Printing Becomes Manufacturing
The final stage of automotive additive manufacturing is producing end-use components.
Rather than focusing on mass-market vehicles that require millions of identical parts, industrial 3D printing shines when producing lower-volume, highly customized components.
During the interview, Fadi highlighted a camera housing bracket produced for Roush and its aftermarket Ford F-150 program. Since the company manufactures approximately 2,000 units annually, additive manufacturing allows them to produce an entire week’s worth of parts in a single build instead of investing in expensive tooling for injection molding.
This flexibility makes industrial additive manufacturing especially attractive for specialty vehicles, performance upgrades, and limited-production platforms.
Understanding the H350 Powder Bed Process
To support production manufacturing, Stratasys demonstrated its H350 powder-bed fusion system.
Unlike filament printers, the H350 spreads thin layers of nylon powder across the build platform. A print head selectively deposits an energy-absorbing fluid onto each layer before infrared energy fuses only the desired areas. Layer after layer, fully dense parts are built inside a surrounding “cake” of unfused powder that naturally supports the geometry during printing.
Once the build is complete, the parts are allowed to cool before moving to a post-processing station where excess powder is removed and recycled for future builds.
One particularly interesting capability discussed during the interview was Stratasys’ ReLife material program. The H350 can utilize reclaimed powder from other powder-bed fusion systems, allowing manufacturers to convert material that would otherwise become waste into usable production parts.
Industrial 3D Printing Continues to Expand
Walking through the Stratasys booth made one thing clear: automotive manufacturers aren’t relying on 3D printing for just one stage of development anymore.
From creating ultra-realistic concept models, to manufacturing assembly tooling, to producing functional end-use components, additive manufacturing has become integrated throughout the automotive workflow.
As material capabilities continue to improve and production systems become more efficient, it’s likely that industrial 3D printing will continue expanding its role in vehicle manufacturing.
For makers who primarily think of 3D printing as a hobby or prototyping tool, it’s fascinating to see how the same core technology is helping manufacturers design, build, and produce vehicles on a commercial scale.
