A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.

Utilization of magnetic particles to improve z-axis strength of 3D printed objects

An exemplary method of printing medications on digestible substrates is described. Single component nonmagnetic toners with active pharmaceutical ingredients (API) embedded or 'dissolved' in the toner are used. The binders for the toner are digestible. The 'printing' process includes loading the single component non-magnetic toners from a sump to a donor roll and developing them either directly onto the substrate or through the use of an intermediate member. Traditional xerographic charge and exposure can be used to make the tablet 'imprints'. Dosage is controlled through &#x201c;solid area&#x201d; or halftone development (when charge and exposure are used). The &#x201c;printed&#x201d; first layer may undergo cold or warm pressure fusing. This medicament layer is then subjected to another station to &#x201c;print&#x201d; a second layer of medical &#x201c;tablet&#x201d;. Multiple stations may be used to build up a complete personalized tablet. Optionally, a final station prints protective overcoat materials to finalize the &#x201c;tablet&#x201d;.
