Abstract: Printers and associated printer maintenance methods and apparatus are disclosed. A printer including a work area; a temperature sensor to measure a first temperature value at a first region of the work area and a second temperature value at a second region of the work area; and a recoater to distribute a first amount of build material onto the first region and a second amount of the build material onto the second region in response to the first temperature value being a threshold different than the second temperature value.

Abstract: A build material dispensing device may include a material spreader to spread an amount of build material along a build platform, and at least one hopper for dispensing the build material. The at least one hopper dispenses a plurality of doses of the build material in front of the progression of the material spreader as the material spreader is moved over the build platform.
