Devices for deposition of material via organic vapor jet printing (OVJP) and similar techniques are provided. The depositor includes delivery channels ending in delivery apertures, where the delivery channels are flared as they approach the delivery apertures, and/or have a trapezoidal shape. The depositors are suitable for fabricating OLEDs and OLED components and similar devices.

Systems and arrangements of OVJP deposition devices are provided, in which one or more organic material crucibles are directly attached to an injection block and a print head without the need for external delivery components such as feedtubes. Each crucible may be hermetically sealed until it is attached to the injection block, allowing for a single device to provide for storage, transport, and deposition of the organic material.
