| The main objective of this work is to adapt Laser Induced Forward Transfer (LIFT), a well-known laser direct writing technique for material transfer, to cure cements (calcium aluminates base) onto acceptor substrate. LIFT is a promising technique in different biomedical fields due to it is a fast, clean and non-contact direct-write technique that allows the deposition of small volumes of a wide range of materials in a very precise and controlled way. This technique has been used to print in a wide range of viscosities, from solid phase to Newtonian and non-Newtonian fluids. In this work, we present first results using this approach to transfer cements of great interest in biomaterials applications. The calcium aluminate cements are used in dentistry for endodontics. A layer of synthetized cement with thickness in the order of 100 µm is applied over a glass substrate using a blade coater. In the glass with the deposited cement paste is set a controlled gap over the acceptor substrate. A solid-state pulsed laser emitting at 532 nm is focused on the glass/cement interface producing a droplet of paste that it is transferred to the acceptor substrate The process parameters (cement paste thickness, gap and laser parameters -spot size, pulse energy and overlapping of pulses) are modified and the morphology of the voxels is studied using confocal microscopy. | |
