The paper concerns the definition and estimation of uncertainty elements. This topic is matched with Direct Metal Selective Laser Sintering used for manufacturing the samples. The UNI ENV ISO 14253-2: 2003 standard deals with uncertainty sources in dimensional measurement. This paper treats just those ones regarding measurement procedure, measurement equipment and workpiece. The aim of this paper is estimating combined standard uncertainty. Measurement repeatability, workpiece fixing and number of points for the definition of geometric elements arise from measurement procedure. Measurement equipment uncertainty is connected with Maximum Permissible Error. As far as workpiece uncertainty components, surface roughness, form error and temperature are checked.

Abstract
The paper concerns the definition and estimation of uncertainty elements. This topic is matched with Direct Metal Selective Laser Sintering used for manufacturing the samples. The UNI ENV ISO 14253-2: 2003 standard deals with uncertainty sources in dimensional measurement. This paper treats just those ones regarding measurement procedure, measurement equipment and workpiece. The aim of this paper is estimating combined standard uncertainty. Measurement repeatability, workpiece fixing and number of points for the definition of geometric elements arise from measurement procedure. Measurement equipment uncertainty is connected with Maximum Permissible Error. As far as workpiece uncertainty components, surface roughness, form error and temperature are checked.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
