Claim 10:
11. An additive manufacturing device, comprising:
a vessel for containing a material which is polymerizable on exposure to radiation;
a build platform having a build surface arranged to have an object formed on the build surface, the build platform being configured for movement relative to the vessel;
a programmable radiation module configured to produce a dynamic curing pattern, wherein the programmable radiation module is disposed below the vessel to irradiate a layer of uncured material using the dynamic curing pattern such that, on curing, the layer is in contact with at least the build surface to form a layer of the object;
a rigid transparent member disposed between a bottom of the vessel and the programmable radiation module, wherein the programmable radiation module comprises a dynamic mask component and a radiation source for irradiating through the dynamic mask component, and wherein the rigid transparent member is disposed above the radiation source, and
wherein the dynamic mask component and the rigid transparent member are attached to the bottom of the vessel.
