The patent US12064899B2 describes a system for the application of a support material using energy-pulse-induced transfer printing (LIFT). The support material consists of a carefully formulated composition that includes 0.05 to 30 wt.-% of an energy transformation component, which can be an inorganic or organic dye or pigment. Additionally, it contains 5 to 60 wt.-% of a volume expansion component, characterized by a boiling point between 95 to 200°C, and 35 to 94.95 wt.-% of a binder, which may be a polymer, wax, or non-ionic surfactant that remains solid at temperatures below 40°C. The material is designed to have a viscosity ranging from 0.2 Pas to 1000 Pas and a surface tension between 20 to 150 mN/m at 25°C.
Further claims expand on the system by introducing a construction material that may include a ceramic particle suspension, particularly one with 68 to 88 wt.-% zirconium oxide. The suspension is limited to no more than 5 wt.-% organic components relative to the solid content. Additionally, the construction material can incorporate a polymerizable binder, a volume expansion component, and an initiator for polymerization, along with an energy transformation component. Specific formulations are detailed, including the use of radically polymerizable binders and photoinitiators, which enhance the system's functionality in various applications.
