2015-12-08 (Tu) Rubber Stamps From 3D Printer

The eraser used yesterday was purchased from a dollar store in a pack of four. Each eraser was smaller than the name brand Prismacolor eraser but much cheaper. At $0.25 each they were far more affordable than the $0.79 name brand eraser. There didn’t seem to be a difference in the quality of the rubber as it was being used for a stamp. Teacher may want to take note if they intend to purchase erasers for a whole class.

Paper used to shape the eraser

Bulging sides of the eraser needed to be shaped. This could have been avoided if the base had been printed larger than the eraser. Anyone copying this project would be wise to print a larger base than me. Instead, the eraser was shaped using paper. Since erasers are quickly worn away with use a piece of paper was rubbed along the bulging sides to safely remove the unwanted material. Areas where the protruding stamp was close the bulge required extra care so the stamp would not be harmed.

A stamp pad was also purchased from a dollar store. Dollar store stamp pads were little more than a piece of foam soaked in ink. Each eraser had to be rubbed along the surface of the sponge to collect enough ink. More rubbing applied more ink.

 Result of $0.25 eraser

The Prismacolor eraser, one the left, was left as a mirrored image of the desired stamp and tested anyway. This eraser did not have any shaping done and the consequence can be seen on the paper where the edges left a definite imprint. The stamp on the right was shaped and made from the correct mold but it was not rubbed on the stamp pad as much so the image was not as dark.
