Light-sheet 3D microprinting via two-colour two-step absorption

High-speed high-resolution 3D printing of polymers is highly desirable for many applications, yet still technologically challenging. Today, optics-based printing is in the lead. Projection-based linear optical approaches have achieved high printing rates of around 10 6  voxels s –1 , although at vox...

Description
Summary:High-speed high-resolution 3D printing of polymers is highly desirable for many applications, yet still technologically challenging. Today, optics-based printing is in the lead. Projection-based linear optical approaches have achieved high printing rates of around 10 6  voxels s –1 , although at voxel volumes of >100 μm 3 . Scanning-based nonlinear optical approaches have achieved voxel volumes of
