Abstract
A 3D printing system in which paste is used to fill a space enclosed by a 3D printed mold wall, uses a blade for spreading the paste. A cleaning system for the blade includes an immersion bath, which is filled with fluid to a fluid level. Rotating brushes are partly submerged in the fluid, and when cleaning is needed, the blade is located between the brushes. The brushes rotate onto the knife such that each surface of the knife is brushed over to remove debris from the paste into the fluid.
Claims24
A 3D printing system in which paste is used to fill a space enclosed by a 3D printed mold wall, the 3D printing system comprising a blade for spreading the paste, the system comprising a cleaning system, the cleaning system comprising a fluid and an applicator for applying the fluid to the blade to clean the blade after spreading the paste.
A 3D printing system in which paste is used to fill a space enclosed by a 3D printed mold wall, the 3D printing system comprising a blade for spreading the paste, the system comprising a cleaning system the cleaning system comprising a blade holder and air ducts directed at said blade, the air ducts connected to a source of pressurized air.
A method of cleaning a blade of an injection head of a 3D printing mechanism in which layers are formed by injecting paste within walls of a mold and smoothing the paste with the blade to form a layer, the method comprising:
- moving said injection head from a printing station to a cleaning station;
- and
- at said cleaning station applying fluid to said blade to clean said blade.
