Abstract: A build unit for a three-dimensional printer, comprising a housing comprising sidewalls and a build platform movable within the housing. The housing and the build platform form a build chamber. The build unit further comprises a lateral heater mounted on the housing. The lateral heater is operable to apply a uniform housing temperature across all the section of the build unit by delivering variable power density along the housing.
