Better print resolution in 3D printing is achieved by decreasing the layer height and using a finer nozzle diameter.

Decreasing layer height allows for thinner layers to be printed, leading to a more detailed and smoother surface finish. Each individual layer will have less height, which means fewer visible lines in the printed object, resulting in higher overall resolution. This is particularly important for enhancing the level of detail in intricate designs or detailed features.

Additionally, using a finer nozzle diameter allows for more precise extrusion of material. A smaller nozzle can lay down thinner strands of filament, which contributes to better detail reproduction in complex geometries. This combination of finer nozzle dimensions and reduced layer height together enhances the resolution, allowing for more intricate and detailed prints.

Using a larger nozzle and increasing layer height, as seen in other options, generally leads to a faster print but sacrifices quality and detail, which is contrary to improving print resolution.
