Emerging Manufacturing Technology

Printing structural parts layer-by-layer — eliminating tooling costs and enabling geometries impossible by conventional methods.

Additive manufacturing (AM) in automotive has moved well beyond prototyping. Companies like Divergent Technologies are using metal 3D printing to produce full structural nodes, chassis joints and brackets that are lighter, stronger and produced with zero tooling investment. Selective Laser Sintering (SLS), Direct Metal Laser Sintering (DMLS) and Binder Jetting are all used in production automotive contexts today.

Robotic deposition of carbon fibre tapes with ±0.5° precision — faster, more consistent and more capable than hand layup.

Automated Fibre Placement (AFP) machines deposit narrow slit-tape prepreg carbon fibre at programmed angles using a robotic head. This replaces slow, variable hand layup with a consistent, repeatable process capable of producing complex curved surfaces on monocoque tubs, floor panels, and body closures. Companies including Electroimpact, Coriolis and MAG IAS supply AFP systems to hypercar and aerospace OEMs.

Replacing hundreds of welded parts with a single high-pressure aluminium casting the size of a car's entire rear underbody.

Pioneered by Tesla with its 6,000-tonne Giga Press — and rapidly adopted by Volvo, Toyota and others — gigacasting uses ultra-large high-pressure die casting (HPDC) machines to consolidate what were previously 70–100 separate stamped and welded components into a single near-net-shape aluminium casting. This slashes assembly complexity, reduces mass, and improves structural rigidity at joints. IDRA Group and Bühler are the primary machine suppliers.

Solid-state welding that joins aluminium without melting it — stronger, lighter joints with no heat-affected zone distortion.

Friction Stir Welding uses a rotating non-consumable tool to generate frictional heat, plasticising the material at the joint without melting it. The result is a weld with metallurgical properties close to the parent material — far superior to MIG or TIG welding for aluminium alloys. FSW is used in aerospace and increasingly in automotive for battery enclosures, floor structures, sub-frames and heat exchangers. Hitachi, TWI and ESAB are leading technology holders.

Forming ultra-high-strength steel at 900°C then quenching in the die — achieving 1,500 MPa tensile strength impossible in cold forming.

Hot stamping (also called press hardening or hot forming) heats boron steel blanks to ~930°C to make them formable, stamps them in a water-cooled die, and quenches them simultaneously — producing parts with tensile strengths up to 1,500–2,000 MPa. This is how modern cars achieve ultra-lightweight B-pillars, sill reinforcements and roof rails that deliver class-leading side-impact performance at minimum mass. Gestamp, Schuler and Voestalpine are key players.

A real-time virtual replica of the production line that enables simulation, predictive maintenance and instant process optimisation.

A manufacturing digital twin is a live, data-connected virtual model of a production line, machine or product. Sensor data from the physical line feeds the twin continuously — enabling simulation of process changes before implementation, predictive maintenance based on machine condition data, and real-time quality monitoring without physical inspection. Siemens, Dassault Systèmes and PTC lead the automotive digital twin market.
