Additive manufacturing with vat polymerization method for precision polymer micro components production

Applications of dimensional micro metrology to the product and process quality control in manufacturing of precision polymer micro components

Precision manufacturing of micro injection moulded (mIM) components presents challenges in terms of quality control due to the miniaturization of product dimensions and tolerances. This paper addresses product compliance with specifications, focusing on tolerances of dimensions and position on mIM components selected from industrial production. Two systems were analysed: a tactile coordinate me...

Manufacturing of Devices for the Parallel Precision Alignment of Multiple Micro Components

Micro components are available in a variety of shapes typically sizing from 1 mm down to 0.01 mm. Their mass production is quite common using state of the art production technology. Micro spheres for example, are on the one hand available in lot sizes up to some thousands in a constant quality within micron accuracy [1]. On the other hand they are quite commonly provided as bulk material with d...

Deformation Post-processing of Additive Manufacturing Components

Parts produced by additive manufacturing (AM) often require post processing to improve surface finish and mechanical properties. However, little attention has been given to including deformation in the post processing. Deformation post-processing can address some part size, manufacturing cost, and geometry limitations of 3D printing. Additionally, it could be used to create 3D surfaces using pl...

Ultra-Precision Metal Additive Manufacturing for Thermal Management of Microelectronics

Thermal management of microelectronic devices is an ongoing technological challenge that directly affects device-level and system-level performance and reliability [1]. The fundamental process of electron transport in a transistor device results in dissipation of heat. This causes temperature rise, which in turn limits device performance. For most semiconductor devices, performance goes down wi...
