General Motors is in the midst of making a number of announcements regarding facility openings and investments. The latest news reveals that a new facility dedicated to 3D printing has just opened in Michigan; two GM engine plants, one in New York and another in Ohio, are getting upgrades; and subsidiary GM Defense is renovating a center in North Carolina for production.

Additive Industrialization Center

The 15,000-square-foot Additive Industrialization Center (AIC) has opened in Warren, Michigan. The center is new from the ground up and dedicated to the production of 3D parts that will be used throughout the GM lineup. GM is calling the center the "capstone" of their expertise.

"The core component of GM's transformation is becoming a more agile, innovative company, and 3D printing will play a critical role in that mission," said Audley Brown, GM director of Additive Design and Materials Engineering. "Compared to traditional processes, 3D printing can produce parts in a matter of days versus weeks or months at a significantly lower cost."

Inside the facility are 24 3D printers, which create polymer and metal solutions. Machines inside AIC are able to conduct selective laser sintering, selective laser melting, Multi-Jet Fusion, and fused deposition modeling. These technologies will be used to validate various applications for the parts in future vehicles, such as the Cadillac CT4-V Blackwing and CT5-V Blackwing. Chevrolet's race cars have also been trying out the parts.

Additionally, AIC is using the tech to create parts for retooling GM's production facilities. For the launch of the 2021 Chevrolet Suburban and Tahoe, GMC Yukon, and Cadillac Escalade, GM"s 3D printing team printed nearly 100 hand tools. Normally, these tools would be made of aluminum and weight 10 to 40 pounds each. The new designs, printed using carbon fiber, weigh as little as three pounds and have

GM plans to invest $70 million into its Tonawanda, New York engine plant and over $6 million into its Parma, Ohio metal stamping plant. These manufacturing-related investments are being made to support demand for the Chevrolet Silverado and GMC Sierra pickup trucks.

The Tonawanda investment will be used to increase capacity on the engine block machining line and the Parma investment will be used to construct four new metal assembly cells to support increased truck production volumes.

GM's New York plant currently produces the 4.3-liter V6, 5.3-liter V8, and 6.2-liter V8 family of engines for the Chevrolet Silverado, Suburban, and Tahoe; GMC Yukon and Yukon Denali; and Cadillac Escalade. It also builds the 6.6-liter V8 for Chevrolet Silverado HD and GMC Sierra HD pickups. The SUV models have all been completely redesigned for the 2021 model year, a move that is likely to spur increased sales in the model line.

The Tonawanda engine plant is home to approximately 1,300 employees. The plant's hourly workforce is represented by UAW Local 774.

Ohio's Parma Metal Center processes over 800 tons of steel per day and services and supports approximately 35 customers, including the majority of General Motors North America produced vehicles. The plant is capable of producing up to 100 million parts per year.

The plant employs approximately 1,000 employees. Hourly employees are represented by UAW Local 1005.

GM Defense LLC, a subsidiary of General Motors, has begun renovations of an existing GM building in Concord, North Carolina to support the production of the Infantry Squad Vehicle (ISV). The company recently showed off the vehicle, which was part of the contract to create an agile all-terrain troop carrier. GM Defense won the $214.3 million contract for the production of the vehicles from the U.S. Army in June 2020 and the first ISV was delivered in October.

Construction at the 75,000-square-foot facility is expected to continue into early spring, with vehicle deliveries expected to begin in April. The facility will help to manufacture 649 ISVs and will support the production of up to 2,065 vehicles with additional authorization over eight years.

The location of the facility puts it near Hendrick Motorsports, which is already a Chevrolet partner for its various racing teams. Hendrick Motorsports is responsible for providing the chrome-moly steel exoskeleton of the vehicle frame, including the ISV ROPS system.

The Denali Ultimate gets exclusive upgrades over other trims that include 22-inch wheels and chrome accents outside. The full-size SUV just got a complete redesign for 2021, which brought updated boxy styling, and a sleek look, so there are no additional exterior changes for 2023.

A 3.0-liter turbodiesel is also available that makes 277 horsepower and a whopping 460 pound-feet of torque. A ten-speed automatic transmission is standard for all engines, and four-wheel drive is available.

Inside, the Ultimate comes with Alpine Umber full-grain leather upholstery with 16-way power front seats and massaging. Trim-exclusive contrast stitching and aluminum trim accent the space, and the top model gets an 18-speaker Bose audio system with stainless steel speaker grilles.
