Large area deposition type additive manufacturing equipment

A large area deposition type additive manufacturing equipment, comprising:

• a light source module comprising:
• a plurality of light emitting members arranged in an array;
• a light diffusion member comprising a plurality of first micro-structure configured to diffuse light;
• a light enhancement member comprising a plurality of second micro-structure configured to converge the light;
• a light emitting angle limiter comprising a plurality of third micro-structure configured to limit a light emitting angle of the light;
• a dynamic photomask module disposed above the light source module and generating a plurality of photomasks over time;
• a raw material tank comprising a peripheral wall, a bottom wall and a transparent member, wherein the peripheral wall is connected to the bottom wall, and the transparent member is disposed on the bottom wall, and a liquid photocurable raw material is stored in the raw material tank;
• and
• a deposition module comprising a carrying platform and a driving member driving the carrying platform along a first direction to approach or move away from the bottom wall, wherein the carrying platform has a deposition surface facing the bottom wall;
• wherein the light emitting members emit light to pass through the light diffusion member, the light enhancement member and the light emitting angle limiter sequentially to form a curing light having a light emitting angle, the curing light travels through the transparent member and reaches the liquid photocurable raw material, the liquid photocurable raw material is cured and deposited to the carrying platform layer by layer, and the light emitting angle ranges within +30° with respect to a normal line of an incident plane of the light emitting angle limiter.
