Additive manufacturing device with release mechanism

An additive manufacturing device, comprising:

• a vessel for containing a material which is polymerisable at one or more curing wavelengths, the vessel having a flexible wall which is at least partially transparent to radiation at the one or more curing wavelengths;
• a build platform having a build surface, the build platform being movable relative to the vessel to position the build surface such that the build surface faces the flexible wall;
• a curing unit comprising a housing that encloses:
• a rigid component that forms a curing panel having a planar contact surface that faces away from the housing, the rigid component being at least partially transparent to radiation at the one or more curing wavelengths, wherein the rigid component and the vessel are movable relative to each other, such that in a first position, the planar contact surface of the rigid component is in contact with the flexible wall, and in a second position, the rigid component is separated from the flexible wall;
• and
• a radiation module positioned or positionable relative to the rigid component to emit radiation therethrough, wherein the radiation module comprises a dynamic mask component, and a radiation source for irradiating through the dynamic mask component, and wherein the rigid component is separate from the dynamic mask component and the radiation source;
• and
• a conducting device arranged to be in contact with the flexible wall to induce a first electrostatic charge on a surface of the flexible wall, and to be in contact with the planar contact surface to induce a second electrostatic charge on the planar contact surface, wherein the first electrostatic charge is opposite in sign to the second electrostatic charge.
