Removing Solid Support Material from a 3D Printed Gear
Originally Printed Gear
Gear After One Hour
Gear After Three Hours
The gear was treated in a 3% sodium hydroxide solution pulsing a vacuum to produce vapor within the part every 15 seconds. The VCN vacuum removes the spent solution from the internals of the gear and brings in fresh solution to continue dissolution. After 3 hours the gear was completely cleaned and all the gears rotated freely.
