A method for designing and manufacturing a building system in regards to environmental factors including, acquiring a visual image for determining topographic characteristics of a surface, generating a set of architectural geometries in a computing system, creating design models representing an architectural design of the building system, geometric comparison and evaluation of the topographic characteristics with the architectural geometries, selecting a design model for manufacturing the building system, manufacturing a plurality of interlockable building bricks, obtaining a plurality of interlockable modular structure by combining the interlockable building bricks, each of said bricks having a shell portion formed on the inner core of the interlockable building bricks so that the modular structure has common outer surface formed from said shell portion of each brick. The shell portion includes TiO.sub.2 exhibiting a radiation-protective effect and manufacture of the building system in regards to environmental factors.

A method and system for forming vertical wall construction units in one or more provided forms provides environmentally-manageable construction with reduced labor burden over existing non-traditional construction techniques. The method is a method of operation of the system, which includes a programmable controller, a reciprocating tamper head, a positioner that is guided to position the tamper head, and a filling mechanism for introducing loose material to a form in pre-determined layer volumes to provide loose material for individual layers of the prefabricated vertical construction unit. The programmable controller operates the filling mechanism to introduce the loose material for the current layer, then operates the three-axis positioner to guide the reciprocating tamper head over a horizontal cross-section of the form at a height determined for the current layer and along a program-determined path to compact the current layer. The process is repeated until the compacted material reaches a programmed height.

A system for additive manufacturing comprises a dispensing head for dispensing building materials on a working surface, a hardening system for hardening the building materials, a cooling system for evacuating heat away from the building materials, and a computerized controller. A thermal sensing system is mounted above the working surface in a manner that allows relative motion between the sensing system and the working surface, and is configured to generate sensing signals responsively to thermal energy sensed thereby. The controller controls the dispensing head to dispense the building materials in layers, the sensing system to generate the sensing signals only when the sensing system is above the building materials once hardened, and the heat evacuation rate of the cooling system responsively to the sensing signals.

A 3D printer to additively manufacture a 3D object includes a coater, a dispenser, and an energy source. The coater is to coat a first material relative to a print bed to form a selectable number of first layers. The dispenser is to dispense a first fluid agent onto first selected locations of the first layers of the first material. The energy source is to cause fusing at the first selected locations. The dispenser is to also dispense a second fluid agent including a second material to form a selectable number of second layers of the second material at second selected locations on top of the selectable number of first layers. Each second selected location comprises at least some of the fused first selected locations.

A fiber-reinforced prestressed reinforced concrete sleeper is integrally cast and includes a sleeper body and two rail bearing regions. A rail clamping base is arranged on a surface of the each rail bearing region. The two rail bearing regions are located under rails on both sides of the sleeper and the two rail bearing regions are located above the sleeper body. A reinforcing fiber is mixed into the two rail bearing regions only, and a reinforcing rib is arranged in the sleeper body. The reinforcing fiber is concentrated in a main stress region under the surface of the rail bearing regions. The reinforcing fiber arranged in a region with a large stress is more than the reinforcing fiber arranged in a region with a small stress.

The present disclosure is related to a method of producing a fired ceramic article. The method may include: heating a ceramic green body in a kiln, and controlling oxygen concentration in the kiln such that the oxygen concentration swings during the heating of the ceramic green body.

A method of manufacturing precast concrete segments destined to form all or part of a tower (2), the segments being destined to be superimposed within the tower.

The method comprises, for at least a first segment and a second segment destined to be adjacent in the tower, the first segment being destined to be located beneath the second segment, forming said first and second segments using at least one mould comprising a first portion (Ti) and a second portion (Bi) respectively configured to define all or part of an upper face, respectively a lower face of the segment formed therein, the first portion of the mould used for forming the first segment and the second portion (Bi) of the mould (Mi) used for forming the second segment exhibiting respective geometries of complementary shapes.

A build material management system for an additive manufacturing system is described in which a recovered build material tank (208) and a mixing tank (212) are provided. The recovered build material tank (208) comprises an outlet and a first build material filter (218b) for separating a gas flow from a build material flow. The mixing tank (212) comprises a second build material filter (218c). The mixing tank (212) is connected to the recovered build material tank (208) via a RBMT-to-mixer conduit (286). A controller (295) is provided to couple the second build material filter (218c) to a reduced pressure interface to transport build material from the outlet of the recovered build material tank into the mixing tank (212) via the second build material filter (218b). The controller (295) controls coupling of the first build material filter (218b) to the reduced pressure interface to transport build material from a build material source into the recovered build material tank (208). A corresponding method is provided.

A method of manufacturing a three-dimensional object by a layer-by-layer application and selective solidification of a building material by exposure to a radiation. A hollow body is arranged in a process chamber above a build area which hollow body substantially extends from the build area in a direction of an upper side of the wall of the process chamber. Gas is supplied to the process chamber in such a manner and gas is discharged from the process chamber in such a manner that a lower pressure exists in the region of the process chamber lying within the hollow body than in the region of the process chamber lying outside the hollow body.

A method for manufacturing ceramic articles is described comprising a step of feeding, during which at least two different ceramic powders are fed so as to obtain a strip of ceramic powders having at least a first zone and at least a second zone having a given shape; a step of compacting, during which the strip of ceramic powders is compacted so as to obtain a compacted layer of ceramic powders, which is expanded relative to the strip of ceramic powders; a step of determination, during which expansion of the layer of powders is determined; and a step of printing, during which a decoration having a modified shape based on the given expansion is applied on the surface of the compacted layer of ceramic powders.
