In an example implementation, a method of operating a three-dimensional (3D) printing system includes forming a fused 3D object in the printing tray of a 3D printer and vibrating the tray to separate unfused material from the fused 3D object.

Three-dimensional (3D) printing

A fan includes: a housing; and an impeller with an axis and a plurality of blades, the impeller mounted inside the housing; and a plurality of outlets from the housing, each outlet including a cutoff with a top and a bottom. A line between the top and bottom of each cutoff is not parallel to the axis of the impeller.

Fan housing for reduced noise

An apparatus for mitigating noise in a printer can include a plate having a plurality of holes distributed across the plate and extending through the plate. A portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across a given frequency band and another portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across another frequency band in a media path of a printer. The apparatus further can include an acoustic baffling material to cover the plate and that can be configured to dampen the acoustic noise across the given frequency band and the other frequency band.

Noise reduction in printers

An apparatus for mitigating noise in a printer can include a plate having a plurality of holes distributed across the plate and extending through the plate, the holes being dimensioned and configured to mitigate acoustic noise in a printer. A mesh material can cover the plurality of holes, wherein the mesh material can increase air flow resistance through the holes and thereby facilitate removal of acoustic noise from a media path in the printer.

A vibration isolation system, including a housing and a first isolation member which further includes a receptacle to receive an outer body of a motor, a first plurality of compliant arms, and a second plurality of compliant arms. Each compliant arm of the first isolation member has a first end and a second end. The first end of each of the compliant arms is coupled to the receptacle, and the second end of each of the compliant arms is coupled to the housing.

Vibration isolation system

Improved beam-interruption type pest detection devices adaptable to mounting on known pest traps utilizing a focused reflective optical sensor providing reduced clogging risk, increased sensitivity, increased sensing consistency and reduced energy consumption, and which can be electronically networked providing improved pest detection, analysis, and management.

Beetle sensing device and method of use

An imaging pest detection device, adaptable to mounting on known pest traps, utilizing a camera module and LED light providing daily gathering of images of the catch-can interior, thereby providing a remote real-time awareness of trap contents with reduced labor and increased accuracy and immediacy of trap condition.
