Disclosed is a 3D printer 10 having a coater 30 and a coater cleaning device 50. The coater 30 has a container 32 defining an inner cavity 34 for receiving particulate construction material and an output region 36 for outputting the particulate construction material. The coater cleaning device 50 has a cleaning web 52. The coater cleaning device 50 and the coater 30 are configured to move the output region 36 and/or the cleaning web 52 relative to each other for wiping the output region 36 by means of the cleaning web 52.

This new application collects data from indoor and outdoor environments and with that data compiles databases, analyzes that data and finds relationships between pollutants, microbes, matter and diseases in humans, plants and animals. This new application is called the Artificial Intelligence Doctor. The application utilizes artificial intelligence, machine learning and parallel conveyor belts with imbedded microscope slides for the identification and analysis of microbes and matter. The application identifies microbes and matter using static electricity applied to microscope slides imbedded in conveyor belts using light microscopes, electron microscopes, polarized light microscopes, x ray machines, artificial intelligence and machine learning algorithms. The easy transfer conveyor belt system utilizes migration of microbes and microbes from drones and robots for easier identification.

A method includes cleaning a wafer with a brush element where the brush element collects particles from the wafer during the cleaning process. The brush element is immersed in a first cleaning liquid. An ultrasonic or megasonic vibration is applied to the first cleaning liquid. The ultrasonic or megasonic vibration causes the particles to dislodge from the brush element into the first cleaning liquid. The particles contaminate the first cleaning liquid.

A method for controlling damages in cleaning a semiconductor wafer comprising features of patterned structures, the method comprising: delivering a cleaning liquid over a surface of a semiconductor wafer during a cleaning process; and imparting sonic energy to the cleaning liquid from a sonic transducer during the cleaning process, wherein power is alternately supplied to the sonic transducer at a first frequency and a first power level for a first predetermined period of time and at a second frequency and a second power level for a second predetermined period of time, the first predetermined period of time and the second predetermined period of time consecutively following one another, wherein at least one of the cleaning parameters is determined such that a percentage of damaged features as a result of the imparting sonic energy is lower than a predetermined threshold.

Various embodiments of the present disclosure provide a multi-stage system and process for removing debris from plastic sheets (such as tier sheets or any other suitable sheets formed from any suitable material). Certain embodiments of the sheet-cleaning system (10) include a drive assembly comprising a drive roller (211, 212) driven by a drive actuator, an electrostatic-discharge device (220) operable to discharge static electricity, and a cleaning roller assembly (230) comprising a cleaning roller (231, 232) driven by a cleaning roller actuator, the cleaning roller (231, 232) comprising a cleaning implement on at least part of its outer surface.

Described are methods for removing abrasive particles from a polymeric surface, such as from a polymeric surface of a cleaning brush used in a post chemical-mechanical processing cleaning step, as well as related cleaning solutions.

Embodiments of the present disclosure are directed to additive manufacturing apparatuses, cleaning stations incorporated therein, and methods of cleaning using the cleaning stations.

Exemplary embodiments of cleaning buckets are shown and described herein. An exemplary cleaning bucket includes a housing that has a cleaning solution reservoir, a dirty water reservoir and an insert for inserting into the housing. The housing has a first surface. The first surface covers the cleaning solution reservoir. The first surface is configured to allow water to flow into the dirty water reservoir through one or more openings allowing fluid to flow into the dirty water reservoir. The insert further includes a cleaning solution dispensing member located on the first surface, a pump for drawing cleaning solution out of the cleaning solution reservoir; and an activation device for causing the pump to pump fluid from the cleaning solution reservoir to the cleaning solution dispensing member.

A system for moulding three-dimensional products from a mass of one or more food starting materials which are suitable for consumption, in particular human consumption, has a production device having a frame, a mould member provided with at least one mould cavity, the frame supporting the mould member, mass feed means for feeding the mass to the one or more mould cavities of the mould member. The system also has at least one cleaning device for cleaning one or more parts of the production device which come into contact with the mass. The mould member is removable from the frame. The system has a storage device for storing a plurality of mould members, which may be provided with an identification, has recognition means for recognizing the identification of a mould member, and may have a memory for storing at least one history of a mould member.

In one embodiment of the present invention, a cleaning member 90 is attached to the surface of a cleaning member attaching part 10. The cleaning member attaching part 10 has a main body 20, a cleaning liquid introduction part 30 extending inside the main body 20, and a plurality of cleaning liquid supply holes 40 communicating with the cleaning liquid introduction part 30. The cleaning liquid introduction part 30 is configured such that cleaning liquid flows in from a first end part 11 side, and an area proportion of the cleaning liquid supply holes 40 in a second region located on a second end part 12 side opposite to the first end part 11 to a surface of the main body 20 is larger than the area proportion of the cleaning liquid supply holes 40 in a first region located on the first end part 11 side to the surface of the main body 20.
