FIELD: layer-by-layer body formation.
SUBSTANCE: invention relates to a device for layer-by-layer formation of a body from a radiation-curable material, as well as to a method for layer-by-layer formation of a body from a radiation-curable material. Device (1) for installation of layer-by-layer formation of a body (K) from a radiation-cured material (S) contains a container (3) having a bottom (2) for accommodating a radiation-cured material (S), a working platform (4) located above bottom (2) of the tank and adjustable in height relative to the bottom (2) of the tank, and a sensor (5) interacting with the bottom (2) of the tank. Wherein the bottom (2) of the container is at least partially made flexible, and a chamber (6) is provided, which is limited by the lower side of the bottom (2) of the container, while the sensor (5) is designed to detect changes in the volume of the chamber (6) and issue a sensor signal, from which the sign of the volume change can be set, to quantify a measured parameter that is directly or indirectly proportional to the chamber volume or volume change and to provide it as a sensor signal. Wherein the sensor (5) is a pressure sensor (5a) designed to determine the pressure and/or corresponding to a change in the volume of the pressure change of the compressible medium (M) located in the chamber (6), and/or a flow sensor installed in the chamber and intended for determining the volume-related change in the amount of the substance present in the chamber (6) of the fluid medium. In addition, the sensor (5) is designed to provide a measured pressure and/or a measured pressure change and/or a measured change in the amount of a substance as a measured parameter and output a sensor signal.
EFFECT: registration and regulation of technological parameters in the simplest and most reliable way, which ensures fast production of the body by layering with the least possible waste, as well as reliable detection or prevention of faults in the production process.
