The present invention relates to a solid form, particularly to a 3D-printed immediate release solid dosage form (e.g. based on a pharmaceutical, nutraceutical, or food supplement composition). To overcome some of the solubility and disintegration problems inherited by 3D-printed solid dosage forms, the solid form comprises one or more channels, generally in the form of tubular passages or grooves, through the body of the solid form or the surface thereof.

Novel support material formulations, characterized as providing a cured support material with improved dissolution rate, while maintaining sufficient mechanical strength, are disclosed. The formulations comprise a water-miscible non-curable polymer, a first water-miscible, curable material and a second, water-miscible material that is selected capable of interfering with intermolecular interactions between polymeric chains formed upon exposing the first water-miscible material to curing energy. Methods of fabricating a three-dimensional object, and a three-dimensional object fabricated thereby are also disclosed.

Methods of additive manufacturing using noble metals and/or copper metal, and binder compositions for use during the additive manufacturing methods, are generally described. In some instances, the methods of additive manufacturing include de-binding (and in some cases sintering steps) that afford metal-based composites, de-bound metal structures, and metal objects containing noble metals (e.g., silver, gold, platinum) and/or copper that have improved properties, such as relatively high densities. In certain aspects, combinations of certain metal powders (e.g., noble metal and/or copper powders) with certain binder compositions may result in improved properties of resulting metal objects produced by the additive manufacturing process, such as relatively low surface roughnesses. The binder compositions described may include a low molecular weight polymer (e.g., including an acrylic acid repeat unit) and, in some cases, a cross-linking agent.

The present disclosure is related to a method for manufacturing slabs of artificial agglomerated stone comprising: depositing a first layer (1.1) of a first mixture (M.sub.1) onto a surface (2), wherein the first layer having a first thickness h.sub.1, creating at least one cavity (3), having a width w.sub.i and a length L.sub.i, in the first layer (1.1) of first mixture (M.sub.1), depositing a second mixture (M.sub.2) into the at least one cavity (3) of the first layer (1.1), forming a second layer (1.2) by depositing the first and second mixtures, and the second layer having a second thickness h.sub.2, compacting and hardening the second layer (1.2),
wherein the method further comprises after step c) and before step d), inserting a first tool (5) at least partially into the second thickness h.sub.2 of the second layer (1.2), and actuating the first tool (5) wherein the first tool (5) is configured to stir the first wall portion (4.1) while not stirring the second wall portion (4.2).

Additives for three-dimensional build materials or inks are described herein which, in some embodiments, can impart flame retardant properties and/or structural enhancements to articles printed from the build materials. In some embodiments, such an additive comprises a compound of Formula I herein, wherein L and Z are ring substituents comprising at least one polymerizable point of unsaturation, and wherein R.sup.1 and R.sup.2 are independently selected from the group consisting of alkylene and alkenylene, and R.sup.3-R.sup.6 each represent one to four optional ring substituents, each one of the one to four ring substituents independently selected from the group consisting of alkyl, heteroalkyl, haloalkyl, halo, hydroxyl, alkoxy, amine, amide, and ether, and wherein n is an integer from 1 to 7.

Glycerin and sodium polyacrylate may be mixed at a first mixing speed for a first mixing time. Free water and a fibrillated cellulose mixture may be added to second mixer and mixed at a second mixing time speed for a second mixing time. The glycerin and the sodium polyacrylate may be mixed with the free water and fibrillated cellulose mixture at a third mixing speed for a third mixing time. One or more of sodium citrate, sodium bicarbonate, and sodium benzoate may be added and mixed at a fourth mixing speed for a fourth mixing time. Sodium carbonate may be added and mixed at a fifth mixing speed for a fifth mixing time. A surfactant mixture and optionally fragrances may be added and mixed at a sixth mixing speed for a sixth mixing time to form a final mixture, which may be transferred to molds, dehydrated, and removed.

A method for producing a structuring agent for texturing an embossable material surface, in particular a resin-containing laminate surface, including the steps of providing a web-shaped carrier material made of paper and/or plastic, applying a UV-curable lacquer layer made of acrylated oligomer to the carrier material, forming a three-dimensional embossed structure into the lacquer layer applied to the carrier material and curing the lacquer layer by irradiation with high-energy radiation, preferably UV light, during the molding of the embossed structure. The invention provides that before the UV-curable lacquer layer is applied at least one adhesion promoter layer including acrylated oligomer, a reactive diluent and a photoinitiator which reacts to high-energy radiation, preferably UV radiation, is applied onto the carrier material, and that the lacquer layer having the embossed structure is cured by irradiation with high-energy radiation, preferably UV light, to such an extent that, in the finished state, the structuring agent has an average Martens hardness according to DIN EN ISO 14577 in the range from 10 to 80 N/mm.sup.2, preferably in the range from 30 to 80 N/mm.sup.2, the indenter used as a test body for measuring the Martens hardness being pressed into the surface of the lacquer layer having the embossed structure. A structuring agent is also disclosed.
