Rocket engineering is shifting from painstaking machining and welding to a world where engines and tanks emerge from printers ...

3D printing is a powerful tool for creating all kinds of stuff, but it has its limits. Hobbyist-focused machines that dispense melted plastic through a nozzle can only make parts that are so strong.

The promise of 3D printing in automotive applications is clear for all to see, but it still takes clever engineering to get the most out of the futuristic process. It likely won’t come as a surprise ...
