A cleaning system for an additively manufactured component includes a tank storing a cleaning fluid. A fluid circuit is operably coupled with the tank. A pump is coupled with the fluid circuit. A manifold is configured to receive fluid from the fluid circuit through the pump. At least one of a coupler defined by the manifold or a hose is coupled with the manifold. The at least one of the coupler defined by the manifold or the hose is further configured to couple with said additively manufactured component.

A cleaning device is configured to include a first cleaning tank that holds water to which a small amount of an additive is added as a first cleaning fluid, a second cleaning tank that holds water, a water-based cleaning agent, an alkaline cleaning fluid, or a hydrophilic organic solvent as a second cleaning fluid, a first microscopic air bubble generation device, a first circulating pump, an ultrasonic wave emitting device, and a carrier device. Hydrophobic oil is removed by a cleaning target being exposed to the first cleaning fluid including microscopic air bubbles sprayed from a nozzle in an interior of the first cleaning tank, after which hydrophilic oil is removed by ultrasonic cleaning in the second cleaning tank.

The present invention relates to a method for removing a foreign material from the surface of an article comprising the following steps: i) providing an article having a surface covered at least partly with a foreign material; ii) contacting the article provided in step i) with a cleaning medium being an acid having a pKa in the range from −10 to 7 having a minimum concentration of 1 wt.-% and with a carrier medium having a density different from the density of the cleaning medium to obtain a mixture comprising the foreign material solved and/or dispersed in the cleaning medium, the carrier medium and the article free from the foreign material; iii) allowing the mixture obtained in step ii) to separate to obtain a heterophasic emulsion comprising at least a first phase comprising the carrier medium and the article free from the foreign material and a second phase comprising the cleaning medium and the foreign material solved and/or dispersed therein; iv) separating the phases obtained in step iii); and v) separating the article free from the foreign material from the carrier medium. Furthermore, the present invention relates to an installation for carrying out the inventive process.

A method of removing polyvinyl alcohol (PVA)-based scaffold from a 3D printed part formed by a 3D printing process that renders a finished product for immediate use. The method principally involves preparing an acidic-aqueous cleansing solution comprising a mixture of carboxylic acid and water; immersing the 3D printed part conventionally bonded with PVA-based scaffold into the acidic-aqueous cleansing solution for a select amount of time to break down and remove the PVA-based scaffold from the 3D printed part; and adding to the acidic-aqueous cleansing solution a select quantity of polymeric carbohydrate to crosslink and bond with the PVA-based scaffold to effect dissolution thereof into the acidic-aqueous cleansing solution.

A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).

The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a system for washing off residual printing material from a surface of a 3D-printed. In an exemplary embodiment, a chamber is adapted to receive the 3D-printed object and a printing material disruption module is adapted to disrupt a composition of residual printing material on a surface of the 3D-printed object. Additionally, a washing force module may be adapted to apply a washing force field to the 3D-printed object and wash off the residual printing material.

An apparatus for removing powder from a powder-based additively manufactured part includes a chamber for locating a powder-based additively manufactured part therein, a support mesh for supporting a powder cake that includes one or more parts therein, an inlet for introducing a gas into the chamber to flow throughout the powder cake and fluidise the powder to disengage from the part, and an outlet to allow the gas to exit the chamber. The apparatus further includes a cryogenic blasting system for spraying a mixture of liquid CO.sub.2 and compressed air at the powder-based additively manufactured part to remove powder therefrom.

An example method to clean a continuous substrate involves applying a high pressure, low flow spray of a first cleaning fluid at the continuous substrate from one or more nozzles to remove particulate matter from the continuous substrate; transporting the continuous substrate from a first volume having the high pressure, low volume spray, to a second volume having an agitation bath; vacuuming moisture from the continuous substrate during transporting of the continuous substrate from the first volume to the second volume; directing energy at the continuous substrate in the agitation bath using at least one of a megasonic transducer or an ultrasonic transducer; and drying the continuous substrate.

A system and method for cleaning and/or post-exposure of a body manufactured by using an additive manufacturing method from a substance curable by radiation, the system including a cleaning tank for cleaning the body and/or an exposure chamber for post-exposure of the body, the system further including a transport device having a drive for moving a build platform relative to the cleaning tank and/or to the exposure chamber. The transport device includes a force sensor, the force sensor captures a force acting on the build platform and provides a force signal, and is connected to a processing unit for controlling the drive and/or for outputting process parameters based on the force signal.
