A molding system and method, allowing for the repeated use of the same molding insert for purposes of elaborate objects molding is described. The proposed method allows for multiple moldings of intricate shapes and curvatures improving the mass production of the jewelry moldings. During the process, the raw molding material is squeezed through the narrow opening inside the mold form under pressure. As the molding material enters the mold form, it is coated with a coating fluid. After the curing, the molding material could be easily removed through a narrow cavity opening, promptly reassembling back to the shape of the insert for continuous use in the next steps of the molding procedure.

An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

In one aspect, composite build materials for use with a 3D printing system are described herein. In some embodiments, a composite build material described herein comprises a carrier ink comprising a curable material; and pigment particles dispersed in the carrier ink, wherein the pigment particles comprise mica. In some cases, the carrier ink is present in the composite build material in an amount of about 80-98% by weight, and the curable material comprises one or more species of monomeric and/or oligomeric (meth)acrylates. Additionally, in some instances, the pigment particles are present in the composite build material in an amount of about 2-8% by weight and comprise up to about 85% by weight mica, based on the total weight of the pigment particles. The pigment particles, in some cases, can also comprise TiO.sub.2 and/or Fe.sub.2O.sub.3.

Silicone is placed between an upper die and an injection-pressing rubber-lid upper die, and the silicone injection passage is pressurized by the injection-pressing rubber-lid upper die. With this, the silicone is caused to flow into an injection port through the silicone injection passage. Then, sequentially through the injection port and the disc silicone-flow passage, the silicone is caused to flow toward an inner periphery of a silicone injection space. Further, the silicone flows between both circumferential sides of the silicone-flow deflection region. In this way, the silicone flows in a peculiar manner in conformity with a shape of the silicone-flow deflection region.

A sand based jewelry and methods of making sand based jewelry is provided. The jewelry having a quantity of sand mixed with a quantity of binding medium. The binding medium and sand mixture are capable of being solidified and mounted to a jewelry setting. The jewelry setting attached to a jewelry item.
