The technology disclosed relates to high utilization of donor material in a writing process using Laser-Induced Forward Transfer. Specifically, the technology relates to reusing, or recycling, unused donor material by recoating target substrates with donor material after a writing process is performed with the target substrate. Further, the technology relates to target substrates including a pattern of discrete separated dots to be individually ejected from the target substrate using LIFT.

A method of forming a catalyst is provided herein. The method comprises combining a binder, a support, and an active metal to form a slurry composition. The method further comprises applying the slurry composition using an additive manufacturing process to form a green part. The method further comprises exposing the green part to heat at a temperature of from about 10° C. to about 150° C. to form the hardened part. The method further comprises applying a ceramic-based coating material to the hardened part to form the catalyst.

A method for the additive manufacturing of an elastomer part, includes—the creation of a model of spatial coordinates of the part; followed by—the corresponding deposition of an elastomer material. The deposition is carried out in a plurality of substantially flat layers which are vertically stacked. The elastomer material is deposited in the form of a latex-based liquid composition having a dispersion of polymers in an aqueous base, and the deposition is carried out by formation and pressurized ejection of drops of a liquid composition.
