I am looking into the possibilities of 3D printing a ceramic food container for storing wet food. I am wondering what are the specifications of SLA/DLP and Jet Binding when it comes to printing ceramic.
The object is determined to be food safe after it is glazed. The object should be tested to see if it is taking on water. The glaze is the most important part for making a food safe object. Our materials do not give off any toxins after firing.
DLP can achieve faster print times for some parts, as each entire layer is exposed all at once, rather than drawn out with a laser.
This faster print time applies in two cases. For large, fully dense prints, where the print will fill up much of the platform, each layer is exposed faster than it would be if drawn out by a laser. For very small, finely detailed prints, it can be possible to swap out projector lenses according to the area of build volume, and consequently use a narrow amount of light to more quickly build small layers.
Though faster, printing full volume with DLP introduces tradeoffs in resolution and surface finish, whether with large parts or sets of many smaller, finely detailed parts.
