German hypercar manufacturer Apollo Automobil has unveiled the Dragon Skin exhaust for its track-only EVO hypercar, a fully 3D printed, single-piece titanium system produced using laser powder bed fusion and aerospace-grade TA15 alloy. Taking 123 hours to print, it is claimed to be the largest one-piece additively manufactured exhaust ever produced, and represents a component geometry that conventional fabrication methods could not replicate.

Form Follows Function: The Engineering Behind the Dragon Skin

Rooted in Apollo’s dragon-themed design language, the texture actively contributes to thermal management, distributing heat across the structure rather than concentrating it at specific points. A high-temperature ceramic coating rated to 1,000°C is applied over the TA15 alloy substrate, enabling the system to withstand the extreme operating conditions generated by the EVO’s Ferrari F140 V12 engine.

Single-piece construction was central to the engineering brief.…
