Abstract: The present device has been designed as a 3D printer for semi-industrial applications by using fused deposition modeling (FDM). The fixed-bed configuration allows for reducing vibration errors on workpiece caused by moving beds while the specially designed mounting brackets facilitate changing all stepper motors on every axis. In addition, multiple stepper motors have been included along each axis to reduce step-out errors, and each component has been connected to a separate power supply in order to attenuate noise and improve production time. All these factors together allow for easily removing its mixed heat bed from the head to use the device simultaneously in 3D printing, CNC turning, and laser cutting.

Abstract: In one example, a three-dimensional (3D) printing method is disclosed. The 3D printing method may partition an entirety of a powder bed into a plurality of portions including a first portion and a second portion. The method may position an energy source over first portion of the powder bed, apply irradiation to the first portion until an irradiation dose is reached, and turn off irradiation to the first portion of the powder bed. The 3D printing method may rearrange the energy source and the powder bed to position the energy source over a second portion of the powder bed, apply irradiation to the second portion until the irradiation dose is reached, and turn off irradiation to the second portion of the powder bed.

Abstract: In some examples, an apparatus includes a spreader, and a support to which the spreader is mounted. The support carries the spreader that is moveable along a first direction to spread a powdered build material over a build bed. The support includes a base to contain the powdered build material within a boundary of the build bed, and a wing attached to the base, where a bottom surface of the wing is elevated by a distance from a bottom surface of the base, and the wing is to maintain a height of a portion of the powdered build material outside the boundary below a specified height.
