For alignment-free stereo extension with geometric accuracy under various static and dynamic beam array configurations, a method of hybrid layering is proposed based on the redundancy that is analogous to the number of additive layers. Through the proposed method, both a dynamic resolution enhancement effect in the scan and step directions and an additive fabrication effect in the axial direction are achieved. Focusing on conical surface fabrication, the effect of stereolithograpy parameters on pattern fidelity is investigated and the results are analyzed. To correct the tip rounding of a conical surface, the proposed method is modified by inserting auxiliary layers into original layers in a single scan. The potential for improving pattern fidelity through tip rounding correction is demonstrated through critical shape error measurements. The stereolithograpy simulation results reveal that the proposed method is versatile and reliable for conical microlens array fabrication and further for hollow microneedle array fabrication.
