5 Post Processing the Part

5.1 Tips on Gross and Fine Depowdering

• Become familiar with where the parts are placed and how they are oriented in the build

box so you do not accidentally bump or brush against a fragile part during the

depowdering process.

• When performing the gross depowdering (removal of excess powder in the build box)

do not plunge the vacuum nozzle into the powder bed. Begin at the outer perimeter of

the build box, slowly work your way into the build. Hold the tip of vacuum nozzle

approximately 0.25” (6.4 mm) to 0.375” (9.5 mm) away from the powder and allow the

vacuum to pull the powder up. Slanting the vacuum nozzle will enable you to control

the suction. This will decrease the chance of breaking a part that is hidden beneath the

surface of the powder.

• While fine depowdering in the depowderer, always start with a low air pressure and

gradually increase the pressure as the fine details and features of the part become

visible. When the top and sides of the part are completely depowdered tilt the part onto

one of its sides. Handle the part carefully. The part may be fragile and brittle before

infiltration. If none of the sides of the part will be able to support the weight of the part

you can apply a small amount of resin or epoxy to strengthen it. You want to be careful

not to let any of the infiltrant come into contact with any unprinted powder that may still

be on the part. Let the infiltrant dry before continuing to depowder.
