A high flexural strength high density environmental friendly artificial glass composite slab and the preparation method, spherical glass sand or spherical glass powder, filler, unsaturated resin, curing agent, coupling agent, pigment paste and toner. The glass sand or the glass powder has high hardness, good light transmittance, and a smooth surface without pores. The glass powder, filler powder and a hollow glass microspheres fill the gap among the spherical glass sand or the spherical glass powder, and mutually mesh with each other to form a high-density structure. The resulting glass composite slab has the advantages of high strength, high density, wear resistance, shining gloss and good light transmittance, while the surface is smooth and is not likely to be subjected to staining, and it is environmental friendly, non-toxic and non-radioactive.

The invention further relates to a method of making the first structure and to a corresponding phantom.

A device for producing a dental brace, the device including a tooth model; a brace foil; and a separation foil, wherein the separation foil and the brace foil are jointly deep drawn over the tooth model, wherein the separation foil is arranged between the tooth model and the brace foil and separates the tooth model them from the brace foil, wherein the separation foil includes a free standing gripping portion distal from and not in contact with the tooth model, and wherein the free standing gripping portion is grippable by hand.

A three-dimensionally printed internal organ for a crash test dummy is made of a foam type material and has a plurality of defined and varied cell structures and is adapted to be disposed within a torso area of the crash test dummy to measure a regional pressure for the crash test dummy that provides for evaluation of potential abdominal injuries during vehicle crash testing.

The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.

The present disclosure may be embodied as a method for creating a restriction pattern from a mask material having a strain (.sub.mask) an for mapping elastomeric membrane having a strain (.sub.membrane) into a target 3D shape. The method may include discretizing the target 3D shape into a plurality of radial segments, and a radial strain (.sub.r) is determined for each radial position (r) on each radial segment of the plurality of radial segments. A restriction pattern is determined, wherein the restriction pattern comprises a quantity of mask material for each position r to provide a composite strain (.sub.mask,.sub.silicone). In some embodiments, the method further includes depositing a first membrane layer into a mold and placing mask material into the first membrane layer according to the determined restriction pattern. The first membrane layer is cured.

A method of forming a transparent 3D object and a transparent 3D object formed by the method are provided. A transparent 3D object may be formed as follows. An internal structure of a 3D object is printed using a 3D printer based on a 3D image file having information about an internal region of the 3D object, and a mold, designed to form the 3D object and divided into at least two regions, is printed using the 3D printer based on the 3D image file. Then, the internal structure is combined with an inner region of the mold, and a transparent material is supplied to the mold. After the transparent material hardens, a transparent 3D object is obtained by removing the mold.

Disclosed is a completely recyclable artificial turf, which solves the problem of difficult totting of the existing artificial turf, has high tufting efficiency, has high strength of artificial turf, and is capable of being integrally recycled. The completely recyclable artificial turf of the present invention comprises artificial yarn and base fabric, wherein the base fabric includes woven fabric, the artificial yarn is tufted on the base fabric including woven fabric, the root of the artificial yarn is melted or locally melted, and the artificial yarn is integrated with the base fabric into a whole after cooling and shaping, wherein the material of the artificial yarn has a melting point lower than that of the material of the base fabric.

The present invention generally relates to artificial turf, and more particularly to an artificial turf that is fully recyclable, as well as to a production method for manufacturing such an artificial turf. According to a first aspect of the present description, artificial turf is provided arranged for use as a sports field. The artificial turf comprises at least a substrate, artificial turf fibers and a coating, wherein at least first artificial turf fibers are attached to the substrate, and wherein the substrate is further provided with the coating for providing a tuft withdrawal force of the first artificial turf fibers of at least 30 Newtons. The first artificial turf fibers are made of polyester and/or co-polyester, and the coating is a polyether sulfone adhesive for completely recycling the artificial turf into polyester granules.

A monolithic injection molded plastic part including an interior core, a surface formed as a monolithic structure with the interior core, and a distribution of hollow cells formed within the interior core during an injection molding process from a blowing agent and methods for making the same are provided. Such methods include preparing a mixture of unmelted plastic resin, filler agent, and blowing agent, melting the mixture into a viscous combination using a standard injection molding machine, injecting a set amount of the viscous combination into a hollow cavity of an injection mold secured within the standard injection molding machine, and holding the set amount of the viscous combination in the hollow cavity at a low pressure for a hold time until the viscous combination sets into a monolithic structure at least partially filling the hollow cavity and the blowing agent forms a distribution of hollow cells throughout the monolithic structure.
