1. 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 thereon, the build platform being configured for movement relative to the vessel; and
a programmable radiation module configured to produce patterned radiation to cure the material in the vessel, wherein the programmable radiation module comprises a dynamic mask component, and a radiation source for irradiating through the dynamic mask component, and wherein the programmable radiation module is disposed underneath a bottom of the vessel; and
a rigid transparent member disposed between the bottom of the vessel and the programmable radiation module, wherein the rigid transparent member is disposed above the radiation source, and wherein the rigid transparent member and the dynamic mask component are attached to the bottom of the vessel.
