Description
Technical field
The continuous 3D printing method based on Micro LED that the present invention relates to a kind of.
Background technique
Stereo lithography (SLA) is a kind of important 3D printing method, is chiefly used in the 3D printing of photosensitive resin.SLA skill
The light source of art is divided into two kinds, and one is point light sources, and one is area sources.It is the DLP technology of representative due to using using projection lithography
Area source substantially reduces the time of every layer of scanning, to save the print time.And traditional projection pattern needs for complexity
Light path system, and thermal discharge is big in exposure process, so that working interface is unstable.
To improve drawbacks described above, the present invention provides a kind of novel continuous 3D printing methods based on Micro LED.
Summary of the invention
