N2 - Micro-fabrication has been used for many application at engineering such as micro gear, micro heat exchanger, also nowadays can be applied at biological or medic such as micro needle, micro fluidic and bracket orthodontics. The objective of research to modify the surface on steel SKD 61 material to get optimum surface roughness & contour of bracket mesh using FeCl3 as enchant with various pattern (circle pocket, square pocket & inter-hexagonal channel) of maskless photolithography to know the feasibility of mold bracket orthodontics fabrication that appropriate with teeth contour. From this research, the result of material removal profile for macro µ-feature has good enough specific dimension contour/profile. The depth result shows optimum depth 175,4 μm (Pocket) & 170,7 μm (Channel) close to ideal depth of bracket orhtodontics150 μm. The roughness result shows optimum Ra 0,51 μm (Pocket) & 0,63 (Channel) μm close to ideal Ra of bracket orhtodontics 0,53 μm. The profile shape of material removal has U-shape with various curve on left or right side with conical shape on bottom (feasible for injection molding) so has potential to be applied on mold bracket orthodontics.
