3D Printed Mini Turbo Jet

China has successfully completed the maiden flight of a 3D-printed miniature turbojet engine in Inner Mongolia, marking the country’s first flight-validated engine in the 160-kg thrust class entirely manufactured using additive methods and topology optimization.

Developed by the state-owned Aero Engine Corporation of China (AECC), the engine’s design leverages computational modeling to optimize material distribution, enabling the creation of complex components without traditional casting or forging.

While Western firms have long used 3D printing for select parts, AECC’s full-engine application highlights a potential path to reduce reliance on foreign engines, though scaling production will demand advances in materials, quality control, and certification.

Can’t wait for this

Amazon is officially piloting humanoid delivery robots—highly advanced machines that walk upright, carry packages, and communicate with smart home devices. These robots are designed to navigate real-world environments with ease, using onboard AI to avoid obstacles and recognize delivery zones like porches, mailboxes, and secure drop-off lockers. Unlike drones or delivery vans, they mimic human motion, making them ideal for steps, sidewalks, and complex urban layouts.

This ambitious project is part of Amazon’s long-term vision to automate last-mile logistics. The robots are powered by clean energy and synced with Amazon’s fulfillment system, allowing them to coordinate routes with delivery drones and vehicles. As sightings of robot couriers increase in suburban test zones, the future of doorstep delivery might soon involve a friendly metallic visitor instead of a driver.
