In one example in accordance with the present disclosure, a build material volume transportation device is described. The build material volume transportation device includes a shuttle to transport a build material volume. The shuttle includes an opening therethrough to receive the build material volume. The build material volume transportation device also includes a build tray to raise the build volume into the opening in the shuttle. The build material volume transportation device further includes a latch assembly to releasably secure the build tray to the shuttle. A tip of the latch assembly extends to interface with the aperture to secure the build tray to the shuttle. The tip rotates independently of the piston.

There is a problem that when a silver powder sintering paste that is substantially free from resin is used, an organic solvent used as a dispersion medium bleeds, which results in contamination and wire bonding defects. In order to solve the problem, provided is a metal powder sintering paste that contains, as a principal component, silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm and further contains an anionic surfactant but is substantially free from resin.
