A 3-D printing system comprising a plurality of printers. The printers are motorized to allow movement in X and Y directions or to rotate freely. Each printer may have one or more printheads. Also provided is a surface independent from said printers adapted to receive a printed object.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

Functional modules of a modular system include a magnet and at least two conductors, at least one of which is movable into the functional module and at least one of which is formed of ferrous material. The movable conductor is biased against movement into the functional module and is positioned such that it contacts a power delivery conductor before the other conductor of the functional module contacts another power delivery conductor. The magnet provides attraction between the functional module and a power delivery module that assists in overcoming the bias against movement of the movable conductor into the functional module.
