Abstract: A device for producing a three-dimensional structure from a receiver includes a deposition unit that deposits toner on the receiver. That unit is controlled by a controller to produce a toner pattern on the receiver. A fusing device includes first and second rotatable members having respective, different compliances and a mount that selectively retains the members with respect to each other to form a fusing nip and permits adjustment of respective forces between the members at each end. A directing unit entrains the receiver around the second member so that the receiver passes through the fusing nip. A softening device softens the toner of the toner pattern so that as the second member rotates through successive revolutions, corresponding layer areas of the receiver are defined and the softened toner in each layer area adheres to the second surface of the receiver in an adjacent layer area.
