Purpose – The paper's aim is to show the development of materials and methods which allow freeform fabrication of macroscopic Zn‐air electrochemical batteries. Freedom of geometric design may allow for new possibilities in performance optimization. Design/methodology/approach – The authors...
Purpose – Particle velocity is a critical factor that can affect the deposition quality in manufacturing processes involving the use of a laser source and a powder‐particle delivery nozzle. The purpose of this paper is to propose a method to detect the speed and trajectory of particles during...
Purpose – This paper seeks to present the results of a study carried out within rapid manufacturing (RM) service providers and engineering centres in Northern Spain. By disclosing strategies for their everyday operation, it is intended to show how the internal expertise acquired overtime copes...
Purpose – The purpose of this paper is to propose to overcome the limitations of polygonization of point clouds for rapid prototyping purposes, by using a direct slicing approach, based on a hybrid local‐genetic algorithm to achieve a robust direct slicing system. Design/methodology/approach...
Purpose – The paper aims to evaluate mechanisms for silicon overfilling including volume expansion of silicon on solidification for composite silicon/silicon carbide (SiC) objects generated using post‐process infiltration of selective laser sintered (SLS) SiC preforms....
Purpose – To investigate the effects of the infra‐red power level on sintering behaviour in the high speed sintering (HSS) process. Design/methodology/approach – Single‐layer parts were produced using the HSS process, in order to determine the effect of the infra‐red power level on the...
Purpose – This paper aims to verify a new method for accurate part manufacturing using a 3D printer. In particular, the direction and position dependence of the printed results are to be verified within the building area. The results of the accomplished experiments are to be used for the...
