ETH Zurich’s Swissloop: Advancing Hyperloop Innovation with Additive Tooling

20 Nov 2025

Swissloop, a student-led initiative at ETH Zurich, works to advance hyperloop transportation technology by designing and building high-performance capsule prototypes. Each year, a new team builds on the successes of previous teams, improving on technical innovations and gaining hands-on experience. One focus of this year’s effort involved improvements to the pressure cabin, the passenger or cargo “pod” designed to withstand the vacuum and pressurization demands of a hyperloop system.

The Swissloop students tasked with pressure cabin development partnered with Replique, an innovative German contract manufacturing platform and sponsor, who suggested 3D printed tooling for quick turnaround cost efficiency. Replique turned to 3D Systems, whose Application Innovation Group collaborated with the Swissloop team to deliver custom tooling using an EXT 1070 Titan Pellet printer and CF-ABS material.

The machined epoxy tooling blocks traditionally used for high-temperature carbon fiber layup are expensive, heavy, and prone to damage after repeated use. Swissloop instead chose a two-step process, first using the 3D printed layup tool with a room-temperature dry-fiber vacuum infusion process to create an autoclavable, light weight carbon fiber mold, then using that mold to layup the high temperature prepreg carbon fiber for the final parts. 

Compared to traditional tooling, the additive-hybrid approach reduced cost, weight, and waste while improving durability and scalability. 

In this session, Elias Attallah, Mechanical Engineering Student, ETH Zurich, will be joined by André Metzger, Technical Sales Manager and Applications Engineer, 3D Systems to showcase how additive manufacturing can accelerate development cycles and enhance production process innovation in next-gen transportation systems.
