  • Patent number: 12194677
    Abstract: An apparatus and method for removing support material from a part formed by three-dimensional (3D) printing. The support removal machine contains a tank for submersion of a 3D printed part into a liquid mass. The liquid mass circulates in the tank in a controlled manner such that submerged parts remain centrally suspended in the tank, regardless of the material, density and geometry comprising the part. The part circulates and rotates in conjunction with the rotational flow of the liquid mass for uniform exposure to means of support removal. During rotation, the part may be subjected to multiple means of agitation that include heat, chemical and ultrasonic, in order to optimize energy use and maximize efficiency of the removal of support material.

  • Patent number: 10857764
    Abstract: Treatments are provided to strengthen adhesion of an optical filter layer in a photovoltaic (PV) module to an encapsulant layer, or generally, between inorganic materials and organic polymers. The embodiments disclosed herein can provide five or more times the adhesive forces of untreated encapsulant-filter interfaces. As a result, the system can enhance long-term reliability of PV modules by reducing interface surface charges and dangling bonds and reducing gaps and cracks, thereby preventing moisture, impurities, and particles from entering the interface. The treated optical filter layer can result in a surface modification. In some embodiments, treating the optical filter layer includes applying a chemical treatment such as an acid or alkaline wash, and/or ultrasonic cleaning.
