DETROIT — Automakers together with Ford Motor and Rivian Automotive are leaning into a brand new sort of producing line: 3D printing.
Producers say it is serving to them cut back prices and improve pace. The expertise has been round for many years, however it’s changing into extra commoditized within the automotive trade, with 3D printers used to create all the pieces from car elements and equipment to instruments for meeting crops and testing models for analysis and growth labs.
“At this level, we do not have a selection however to scale up and start utilizing it by way of all factions of Rivian,” Jared Beck, head of Rivian’s additive manufacturing, advised CNBC throughout a tour of the automaker’s expansive 3D-printing operations in suburban Detroit. “We will be democratizing 3D printing for the complete firm.”
The advantages of 3D printing
Often known as additive manufacturing, 3D printing can create three-dimensional objects from digital designs by dishing out materials layer by layer, very similar to a conventional printer does with ink on paper. As an alternative of ink, the machines use all kinds of supplies comparable to plastics, composites, ceramics and even metals.

Printers can vary from a whole bunch of {dollars} for hobby-like units to a whole bunch of 1000’s of {dollars} for specialty tools, relying on how large the product being produced is and the fabric it wants. They will produce particular person items or a whole bunch of smaller elements in a batch utilizing powders and resins.
Rivian mentioned it has spent greater than $5 million on 3D-printing machines, with the price of supplies for the operations rising to about $1.7 million yearly.
Beck mentioned regardless of the prices, the machines usually pay for themselves inside a 12 months. He mentioned the expertise helps decrease provider tooling prices, streamline logistics bills and lower manufacturing occasions for elements from weeks to days, if not hours.
“It is nicely within the thousands and thousands [for savings], however the principle factor is pace for Rivian,” Beck mentioned.
The all-electric car firm’s newest enlargement of 3D printing consists of including new machines that may construct versatile silicone elements in addition to putting in a bay of machines at its plant in Regular, Illinois, for workers to print elements on demand.

“3D prints ought to be available for each engineer in order that they will make an element and get it of their arms as quickly as doable,” Beck mentioned.
Rivian has additionally used the expertise for electric-motor fashions for fluid testing, creating screw guides for tooling and stamping press inserts and a few manufacturing elements, together with trim items to fill gaps in some early builds.
GM, Ford
There is a comparable push underway at bigger, more-established automakers like Ford and its crosstown rival Basic Motors, which have used 3D printing for a few years, together with of their huge meeting crops.
As an alternative of getting a bay of 3D-printing machines like at Rivian, Ford has departments for additive manufacturing at lots of its crops to supply and distribute wanted elements. That features a new merchandising machine for 3D-printed elements for manufacturing of F-150 pickup vans close to its Dearborn, Michigan, headquarters.

“By placing the merchandising machine up, all of the staff leaders have entry,” mentioned Gregory Foresi, a Ford mechanical engineer who ran Ford’s 3D-printing lab on the plant from 2024 till final month. “We’re in a position to preserve that factor stocked fairly than have a bunch of elements laying round within the lab. In order that’s been fairly large.”
Foresi used roughly two dozen machines to print off 1000’s of instruments, a few of which have been designed by workers, comparable to torque bit sockets, hood jackers and hand instruments for smoothing adhesive.
Workers can use an app to request that particular auto elements or instruments be printed. Ford’s 3D-printing groups assist develop them or decide what to supply subsequent, because the machining time to construct totally different elements can vary from hours to days, if not weeks.
Foresi mentioned creating the instruments with 3D printing has allowed the automaker to uniquely design them when wanted, get them sooner and, in lots of instances, obtain them at a decrease price.
Ford additionally has used 3D-printed elements to assist preserve manufacturing working. For instance, Foresi mentioned a big machining wheel was wanted to take care of meeting line manufacturing and the corporate was in a position to 3D print the half till a everlasting alternative from a provider was out there.

“They did not carry out as nicely, and it is not likely a alternative for those that we had been buying, however they saved the plant working,” Foresi mentioned.
Ford mentioned it expects to have 3D labs deployed at greater than 23 crops by the tip of this 12 months. Its present 3D-printing program has greater than 200 machines, and there are further printers exterior the official program, the corporate mentioned.
GM has used 3D-printed elements for a few of its low-volume merchandise along with analysis and growth and inside crops, together with lately increasing its use of industrial Stratasys printers that may price a whole bunch of 1000’s of {dollars} primarily based on use case, coaching and certification.
The Detroit automaker makes use of 135 elements which might be 3D-printed for its bespoke Cadillac Celestiq in addition to different elements for its efficiency Cadillac Blackwing sedans, together with a singular medallion on the handbook shifter knob.
Fadi Abro, senior international director of automotive and mobility at 3D-printing firm Stratasys, mentioned GM has been an important instance of how firms can “standardize after which scale” 3D printing.
“The fabric properties improved so considerably that the use instances improved,” he mentioned, noting the corporate works with nearly each main automaker. “From a product perspective, we’ve to get the expertise to grow to be sooner and extra accessible, in an financial sense.”
