This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A process for the production of an article for the cladding of floors or walls, comprising the steps of, in a mold: a) optionally applying a gel coat layer, based on a first curing polymer resin, on the inside of the mold in order to obtain a coated mold, and b) introducing into the core of the mold or into the core of the coated mold from step a) a filling composition which is based on a second curing polymer resin supplemented with at least one mineral filler, wherein core contains at least 5% wt and at most 20% wt of curing polymer resin, relative to the dry amount of filling composition, and the filling composition contains only one single initiator in a concentration of 0.5% wt to 5.0% wt relative to the amount of curing polymer resin in the filling composition.

This document describes systems and processes for forming stone slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, shower surrounds, tiles, or the like). In some embodiments, the stone slabs may be processed by partially filling a mold with a particulate mineral mix, and preparing a top surface of the particulate mineral mix to received one or more additional materials.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and printing on at least a top surface of the engineered stone.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

A molding machine for synthesizing a stone by means of beats of a heavy hammer includes a base, a heavy hammer mounted on the base, and a driving device for driving the heavy hammer. The base is provided with a material-load zone, and the heavy hammer is configured to beat the material-load zone. A processing method for synthesizing a stone by means of beats of a heavy hammer includes the following steps: burdening; material distribution; shaping; and solidification.

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).

An apparatus for vacuum vibro-compression of mixes arranged on a support comprises a press (12) provided with a press ram (18) having vibratory devices (22), and a pressing surface (16). The press (12) comprises a vacuum bell (24). The apparatus is characterized in that it comprises an entry chamber (44) in the region of the inlet opening (36) of the bell (24) having a first opening (48) which can be controllably closed and opened with a first gate (50) adapted to prevent fluid communication between the outside and inside of the entry chamber (44) and a second gate (52) able to be controllably opened and closed, in the region of the inlet opening (36) of the bell (24), and adapted to prevent fluid communication between entry chamber (36) and the inside of the bell (24) or to allow the passage of the support with the mix from the entry chamber (36) to the inside of the bell (24). The apparatus also comprises an exit chamber (46) in the region of the outlet opening (38), having a third gate (54) provided in the region of the outlet opening (38), able to be controllably closed and opened and adapted to prevent fluid communication between the inside of the bell (24) and the inside of the exit chamber (46) or to allow the passage of the support with the compacted slab from inside the bell (24) to the exit chamber (46), and a second opening (56) which can be controllably closed and opened with a fourth gate (58) which is adapted to prevent fluid communication between the inside of the exit chamber and the outside. A method for vacuum vibro-compression of mixes contained inside a mould, comprising the steps of: inserting a support with the mix inside the entry chamber (44) and closing the first gate (50); generating a given vacuum value inside the entry chamber (44) with the first gate (50) and the second gate (52) closed; opening the second gate (52) and inserting the support inside the bell (24) where a given vacuum value is already present; closing the second gate (52) and performing vacuum vibro-compression of the mix with the second and third gates (52, 54) closed; once vibro-compression has been completed, opening the third gate (52) and transferring the support into the exit chamber (46) where a given vacuum value is already present; closing the third gate (54), restoring the atmospheric pressure inside the exit chamber (46); opening the fourth gate (58) and di

Described herein are three-dimensional (3D) printer systems and methods, which may provide for “continuous pull” 3D printing. An illustrative 3D printer includes: a resin container, a base plate, a light source arranged below the resin container and operable to cure resin in the resin container; and a control system operable to: (a) receive model data specifying a 3D structure; (b) determine 2D images corresponding to layers of the 3D object; and (c) generate control signals to operate the light source and the base plate to sequentially form the layers of the 3D object onto the base plate, wherein the base plate moves a formed portion of the 3D object upward after formation of each layer, and wherein at least a surface of a formed portion of the 3D object remains in contact with the resin in the resin container throughout the formation of the layers of the 3D object.
