A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.

An apparatus and method for creating openings in a material that solidifies is disclosed. The apparatus comprises a rigid board and at least one rigid retainer plate. The rigid retainer plate comprises at least one buoyancy plate to resist the buoyant force of the material that solidifies, at least one hydrostatic plate to resist the hydrostatic force of the material that solidifies, and a retainer tie. The rigid board further comprises retainer plate slots configured to accept the retainer plates. When the apparatus is in use, the retainer plates are inserted into the retainer plate slots and the retainer ties are coupled to formwork panels. The material that solidifies is then poured into the gap between the formwork panels. Once the material is solidified, the formwork panels are removed and the apparatus can be either reused or thrown out. The apparatus may be used with any material that solidifies.

A method of making a fluid channel in a printhead structure includes positioning a printhead die on a carrier; compression molding the die into a molded printhead structure; compression molding a first segment of a fluid channel into the molded printhead structure simultaneously with compression molding the die; and materially ablating a second segment of the fluid channel to couple the channel with a fluid feed hole in the die.

A method of forming an iso-grid structure may include filling multiple pockets of the iso-grid structure with a filler material, attaching a support structure to the perimeter of the iso-grid structure, shaping the iso-grid and support structures, and removing the support structure from the iso-grid structure. The support structure may be thinned and stretched during the shaping process.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.
