    A Delta 3D printer with a partially completed object on the build platform is shown on a white surface, alongside a separate extruder component.
    Researchers at the U.S. Naval Research Laboratory are developing a method for making precise ceramic parts for hypersonic missiles and vehicles. These parts could be made by a 3D printer like this one.
    A 3D printer with a circular platform and vertical extruder is placed on a white table against a plain background.
    Another commercial off-the-shelf 3D printer compatible with ceramics is made by 3D Potter.

    Researchers have 3D-printed hollow cylinders (shown) and tapered and conical discs several centimeters high as they refine their method.
    A spacecraft separates into two parts above Earth's atmosphere, with clouds and ocean visible below.
    SpaceLiner is a hypersonic passenger craft concept created by the German Aerospace Center. In this illustration, the SpaceLiner orbiter separates from its reusable booster stage.
