Zusammenfassung:	Additive manufacturing devices and systems are provided. An additive manufacturing device comprises a vessel containing a material which is polymerisable on exposure to radiation, and a programmable radiation module comprising a dynamic mask component; an array of light emitting elements; and a light regulating disposed on top of the light emitting elements. The light regulating member comprises a light absorbing material, configured to at least lower an intensity of light that reaches the dynamic mask component from the array of light emitting elements, and a plurality of through-holes, each through-hole corresponds to a respective light emitting element of the array of light emitting elements. Also provided is an additive manufacturing method which employs the additive manufacturing device. L'invention concerne des dispositifs et des systèmes de fabrication additive. Un dispositif de fabrication additive comprend un récipient contenant un matériau qui est polymérisable lors d'une exposition à un rayonnement, et un module de rayonnement programmable comprenant un composant de masque dynamique ; un réseau d'éléments électroluminescents; et une régulation de lumière disposée sur les éléments électroluminescents. L'élément de régulation de lumière comprend un matériau absorbant la lumière, conçu pour au moins abaisser une intensité de lumière qui atteint le composant de masque dynamique à partir du réseau d'éléments électroluminescents, et une pluralité de trous traversants, chaque trou traversant correspondant à un élément électroluminescent respectif du réseau d'éléments électroluminescents. L'invention concerne également une méthode de fabrication additive qui emploie le dispositif de fabrication additive.
