Design and optimization of a Holweck pump via linear kinetic theory
(2012)The Holweck pump is widely used in the vacuum pumping industry. It can be a self standing apparatus or it can be part of a more advanced pumping system. It is composed by an inner rotating cylinder (rotor) and an outer ... -
Material extrusion 3D printing and friction stir welding: an insight into the weldability of polylactic acid plates based on a full factorial design
(2022)In this work, material extrusion (MEX) 3D-printed polylactic acid (PLA) thin workpieces were joined via the friction stir welding (FSW) process to evaluate the feasibility and the key features of the process. To ensure the ...
