The invention relates to a method for making an object, the method comprising forming a plurality of sections of the object, wherein the formation of each of the plurality of sections comprises applying at least two substances within an area having the shape of the section being formed, the at least two substances being able to chemically react upon contact with each other to form the section. The invention also relates to an apparatus for making an object, the apparatus comprising: an applicator arranged to apply at least two substances within an area having a shape of a section of the object being made, the at least two substances being able to chemically react upon contact with each other to form the section.
A method for making an object and an apparatus (100) for making the object in accordance with the method is disclosed. A section (124) of the object is formed by irradiating a layer of material (104) with a radiation (116), the layer of material being disposed on a material receiving surface (102) of a flexible element (101) shaped by a shaping member (110) contacting the flexible element (102). The radiation (116) passes through the member (110) and the flexible element (101). The member (110) is tilted to induce a peeling separation of the member (110) from the element (101).
An apparatus (100) for making an object (122) is disclosed. The apparatus has a flexible element (101) having an upwardly facing surface for disposing thereon a material (104) used to make the object, and a member (110) connected to an actuator (112) that can move the member (110). A controller is in communication the actuator (112). A method which may be executed using the apparatus (100) is also disclosed.
A 3D printing device (100) adapted to make a solid object (111 A). The device (100) has a cylindrical surface ( 104) rotatable around an axis (122) of rotation, and an applicator (101) adapted to apply over at least one portion of the surface (104) a material (120) used to make the solid object. The applicator (101) and the surface (104) are displaceable relative to each other in a direction transverse to the axis (122). Disclosed herein are also methods (600, 700) of determining instructions for the device (100).
