An apparatus for the manufacture of an object, the apparatus having a print bed, a stencil, a heater arranged to heat the stencil, and a squeegee. The stencil comprises one or more apertures and is positionable over the print bed. The squeegee is movable to spread a printing material across the stencil and to thereby force printing material through the stencil aperture(s). One or both of the stencil and the print bed is movable to adjust the spacing between the stencil and the print bed.
