Abstract

Laser-induced forward transfer (LIFT) has emerged in the last decade as a practical technique for printing a range of solid-phase materials for applications that span photonics, electronics, displays and biomedicine [1,2].
Usually the shape of the printed pixels is determined by either the profile of the LIFTing laser pulse used (often an apertured Gaussian beam), or via an aperture in the beam path (to create a square pixel for example). The ability to LIFT pixels with arbitrary and complex shapes, e.g. letters, icons, pictures or other unique patterns, that can be varied on a shot-to-shot basis is desirable.
Here we extend the work by Pique [3], who recently demonstrated the use of a nanosecond laser in conjunction with a digital multimirror device (DMD) to control the spatial intensity profile of the incident laser pulses for LIFTing of silver nano-ink pastes. We show experimental results for femtosecond LIFT of a ~500nm-thick solid polymer (PMMA) donor, to produce intact LIFTed pixels of typical dimension ~30µm, with line widths of <5µm that show (for example) hollow regions of order ~10µm.
We will discuss our most recent results for solid-phase LIFT of DMD-shaped pixels, and report our conclusions on limitations for this technique as a general method of LIFTing complex shaped objects.
