The Aura3D A5 Pellet 3D Printer is being used to produce full-scale, high-performance car audio system enclosures directly from industrial-grade plastic pellets.
Car audio enclosures demand a unique blend of mechanical rigidity, acoustical performance and custom-fit geometry. Traditional manufacturing methods often struggle with complex internal cavities for acoustic tuning, lightweight but impact-resistant materials, and tooling and setup costs for short runs. The Aura3D A5 aims to address these challenges.
The production workflow begins with CAD modeling of the enclosure, tailored to the target vehicle’s acoustics and dimensions. Once the model is ready, the Aura3D A5 Pellet 3D Printer executes the full-scale print using ABS or carbon-fiber reinforced pellets. A complete enclosure can be printed within eight hours.
After printing, the part undergoes essential post-processing, which includes support removal and trimming, surface sanding and smoothing, and optional spray painting or finish coating.
The final step involves integrating the enclosure into the car’s interior. This includes mounting speaker units, installing acoustic foam or dampers, and wiring the electronics.
In related news, semiconductor manufacturer Asahi Kasei Microdevices (AKM) and Swedish digital audio company Dirac have partnered to integrate Dirac’s suite of software-defined smart acoustics solutions, AudioIQ, into AKM’s line of automotive audio digital signal processors (DSPs), including its flagship AK7709, to significantly reduce tuning time while enhancing sound quality within vehicle interiors.
