A desktop printing apparatus (100) for 3-D printing an object comprising: a print module (200) and a build module (300) provided in-line in a unitary housing. The print module comprising one or more print heads (230, 230′) for printing a portion of a medium (500) to define a media layer (701) of the object. The build module a build plate (310), and cutting means (321), bonding means and adhesive dispensing means (320) for building the 3D object from a plurality of media layers. The apparatus further comprising a medium transport passage defined in the housing between a medium input and medium output, and a transport means (160) to continuously transport the medium from the medium input along the medium transport passage through the print module for printing and subsequently to the build module for profiling and bonding to define a media layer of the object.
