Lenticular Objects: 3D Printed Objects with Lenticular Lens Surfaces that Can Change their ...
summary
Method that prints lenticular lenses and color patterns onto curved surfaces so objects show different images from different angles: a 3D editor computes lens placement and color maps, ray-tracing preview, and files for a multi-material 3D printer. Geometry choice targets a tradeoff: theoretical lenses support up to 19 viewpoints but practical printing and coating limit quality, so authors recommend ~3 mm lens diameter plus varnish. Physical demos include an AirPods case, a kettlebell shell that shows arrows or a check, a nightstand and secret-message shoes; results work but look worse than renderings.
