System and method for producing a tangible object
First Claim
1. A system for producing a tangible object, including:
- a space of predetermined thickness which can be filled with a fluid;
a reference platform which at least partially defines at least one side of the space;
a phase-transformer, for forming each of a first layer and a second layer of said object by selectively transforming the fluid into a solid in a predetermined area of said space, the forming of each of said layer including performing a first action with respect to said layer, said first action being selected from a group consisting of (a) initiating a step of separating said solid from said platform, (b) separating said solid from said platform, (c) finishing the step of separating said solid from said platform, (d) starting a step of providing the space of a predetermined thickness, and (e) completing the step of providing the space of predetermined thickness;
the forming of each said layer further including determining a value of (a) a relative force exerted between the reference platform and the solid for separating said solid from said reference platform or (b) a parameter which is predictive of said relative force;
an actuator for separating each of said layers from said reference platform by moving the reference platform relative to another side of the space or vice versa; and
a controller connected with an actuator control output to said actuator and/or with a transformer control output to said phase transformer, said controller being configured and effective (a) to control a period of time or a moment in time for the first action with respect to the first layer based on the determined value for the first layer and (b) to control a period of time or a moment in time for the first action with respect to the second layer based on the determined value for the second layer, wherein the determined value for the first layer is different from the determined value of the second layer, whereby a time to produce the tangible object is reduced.

Abstract
A system for producing a tangible object. The system has a space which can be filled with a fluid. A reference platform at least partially defines at least one side of the space. The system further has a phase-transformer which can form a layer of the object by selectively transforming the fluid into a solid in a predetermined area of the space. An actuator can separate the layer from the reference platform by moving the layer relative to the reference platform or vice versa. The system has a controller connected with an actuator control output to the actuator and/or with a transformer control output to the phase transformer. The controller can control the production of the object based on a determined value of the force exerted on the reference platform or the solid or of a parameter related to the force.

20. A method for producing a tangible object, including forming a first layer having a first predetermined shape and a second layer having a second predetermined shape, said forming of each layer including:
-
providing a liquid filled space of predetermined thickness of which at least one side is at least partially defined by a platform; transforming said liquid into a solid in a predetermined area of the space corresponding to the respective predetermined shape; separating said solid from said platform by moving the platform relative to another side of the space or vice versa; said forming of each layer further including determining a value of (a) a relative force exerted between the platform and the solid for said separating said solid from said platform or (b) a parameter which is predictive of said relative force; the forming of each layer including performing a first action with respect to said layer, said first action being selected from a group consisting of (a) initiating a step of separating said solid from said platform, (b) separating said solid from said platform, (c) finishing the step of separating said solid from said platform, (d) starting a step of providing the space of a predetermined thickness, and (e) completing the step of providing the space of predetermined thickness; the method including controlling a period of time or a moment in time for the first action with respect to the first layer based on the determined value for the first layer and controlling a period of time or a moment in time for the first action with respect to the second layer based on the determined value for the second layer, wherein the determined value for the first layer is different from the determined value for the second layer, whereby a time to produce the tangible object is reduced. - View Dependent Claims (21, 22)
