English abstract:
The objective of Lithography-based Additive Manufacturing Technologies (L-AMT) is to enhance the throughput and surface quality in order to compete with traditional manufacturing methods.
We at TU Wien developed an L-AMT system, with a hybrid exposure concept. A laser, focused to 20 μm, shapes the outline of the item whereas a Digital Light Processing Light Engine (pixel size 56 μm) cures the inner area. A dichroic mirror facilitates the beam alignment, controlled by an online-monitoring camera array.
With this combined approach, the system provides surface qualities of Ra < 4 μm and an enhanced throughput with a building volume of 144x90x150 mm3.
