- Start with a desirable image
- Convert it to black and white
- Reduce the image's colors to black or white - with as little gray as possible
- Remove background clutter
- Upload to Shapeways' Rubber Stamper service for production
- Stamp freely!
The service permits you to upload an image with multiple stamp images up to a size of 9x13 cm for only USD$25. We think this service will be quite popular, particularly with children - and apparently Shapeways does too, since many of their promotional pictures involve children's stamps. The only improvement we can think of would be for them to provide an online photo manipulation service that cleans up the picture and directly integrates with the printing systems.
This is yet another simplification of 3D print technology enabling more people to get involved. Yay!
