3D Printing for the Automotive Industry
The automotive sector is undergoing a significant transformation, driven by advancements in additive manufacturing (AM). From manufacturing jigs to full-size prototypes and end-use parts, the opportunities and cost-saving benefits of 3D printing are vast. Global industry leaders like Nissan and local businesses such as Carbotech Ltd are embracing this technology, marking a shift towards mass adoption in automotive manufacturing.
Benefits of Additive Manufacturing in Automotive
Tools, Jigs & Fixtures
- Examples: Ultimaker 3D printers have been used by Audi to produce assembly line tools and jigs, streamlining production processes and reducing lead times. Similarly, BMW has implemented FDM 3D printing to create custom jigs and fixtures for prototyping and small-batch production, improving both precision and workflow speed
- Materials: PLA, PETG, ABS, Carbon-fibre reinforced composites
- Sample Prints: Assembly line jigs, torque wrenches, clamping tools, and alignment guides
End-Use Parts
- Examples: Automotive manufacturers use Raise3D Pro3 with HyperSpeed Kit to produce functional air intakes, engine components, dashboards, and custom brackets. Team Dynamics leverages this tech for bonnet louvers and touring car parts
- Materials: Nylon (PA12), Polycarbonate, TPU, Carbon-fibre reinforced nylon, metal powders
- Sample Prints: Air intake manifolds, engine covers, interior panels, custom brackets
Right to Repair
- Examples: A discarded Ford Fiesta headlight was repaired using an Ultimaker S5 3D printer at a material cost of just £2, compared to £150 for a replacement
- Materials: Transparent resin, PLA, PETG, and TPU for flexible repair parts
- Sample Prints: Headlight brackets, clips, housings, and covers
Metal 3D Printing in Automotive
- Examples: Meltio’s metal AM produces titanium and stainless steel components for high-performance applications
- Materials: Stainless steel, Titanium, Aluminum, Inconel, and tool steel
- Sample Prints: Exhaust components, engine brackets, suspension parts, and heat exchangers
