The Digitization of Materials

A “print in place” design for a shopping list highlights how digital and physical are merging in fascinating ways. It might seem trivial, but this model highlights how integrated the digital and physical can become in everyday life.

This model allows creating a shopping list using a form. The result is a model with your shopping list that you download and print. The form is itself a service defined by the creator of the model. There are other models that offer online configuration before downloading with personalization.

The model editor. The form uses a template provided by the 3D printer, Bambu Lab.

The form includes parameters to assign colors and materials.

I reversed the colors to save ink when printing a scan.

After printing the model, I carefully loosened the toggle buttons that indicate what items are needed from the store.

Finally, I put the list face-down on my inkjet printer to scan what I need.

The first scan showed adhesion problems in the lettering, which was fixed by increasing the bed temperature and slowing the print head. This is still a weak point in the consumer market – too much tweaking and acquired knowledge is required to have a build go smoothly.

The model includes an option to print recesses in the back that accept flush-fit magnets for putting on the refrigerator – this worked very well.
