Post Processing

Basic, essential Post-Processing instructions can be found in the Culinary Studio Post-Processing Guide. However, there are advanced post-processing techniques that can provide multiple benefits to your parts, including: enhanced color vibrancy, a moisture barrier, a more-uniform surface, and added strength for the parts to enduring handling. This section will discuss best practices for these techniques.

Cleaning Tips and Tricks

Air Pressure

The air pressure of the Brill 3D Culinary Finishing Station is variable; you can control it with the knob on the front panel. A good starting point is around 60 psi (Pounds per Square Inch), and can be raised as high as 120 psi. Part size and thickness will dictate the pressure used. Keep in mind that the higher the pressure, the more likely you are to damage the part during cleaning. Start low and, if needed, move up slowly to minimize the chance of damaging your parts.

Brushing

Sometimes physically brushing powder off the finished part is the best way to clean it. Use soft, medium, and/or stiff bristle brushes to gently remove more stubbornly adhered unbound powder from the surface of the part. Keep a selection of food-safe brushes available for this.

Handling

Be as gentle as possible while handling parts during post processing. Do not apply excess pressure to the surfaces or set the part down too forcefully. If you have printed a scaffold with your part, you may keep it on the part during cleaning as added support. 

Color Vibrancy

If parts are intended to be eaten, such as a cocktail garnish, candy, drink sweetener, dessert, or plate up If parts are not intended to be eaten and uniform surface is desired, such as with a cake topper or display item
Apply a fine mist of the following solution: 70% ethanol/30% water. Using a light mist is critical, as using too much solution on parts can cause the parts to dissolve and become sticky and misshapen. Allow parts to completely dry before placing in storage.

WARNING: ethanol is a Flammable material. Take care to avoid causing a fire by igniting flammable material.

Apply a fine mist of coconut spray. Shift the parts on paper a few times during drying to prevent excess oil from solidifying around the base of the parts. Allow parts to completely dry before placing in storage.

Moisture Barrier

It is possible to create a natural barrier from moisture in the air, increasing the strength of your display or gift parts that must have a longer shelf life, but will likely not be eaten. To do this, dip the part in a coconut oil that is solid at room temperature. Avoid oils that contain soy lecithin, which give parts a yellowish/tan color.

Heat the oil to 100-110°F to liquefy. Submerge parts and remove quickly. Place parts on a surface such as oil-absorbent paper that will absorb the excess oil from the parts. Shift the parts on paper a few times during drying to prevent excess oil from solidifying around the base of the parts. Failure to do so can create an opaque surface that is very noticeable on colored parts. Do not store parts at a high temperature, as this risks liquefying the coating.

This technique affects the taste and texture of parts and should be avoided if the parts are intended to be eaten.
