Abstract
The mass production of micro and meso scale products made of polymers or metals is intimately related to the production of high quality microtooling in stable materials capable to provide an accurate and repetitive performance throughout the whole demanded production. As it is widely known, the WEDM process provides high accuracy but is conceptually limited to the production of ruled features. The SEDM process can be a complement to this aspect but the electrodes must be manufactured by other technologies like WEDM, micromilling, turning, etc. Given the importance of several parameters like dimensional accuracy, tooling material for the different replication processes or tooling production technology, the present paper introduces some tests performed by the 4M Metals Workgroup. The analysis of some components manufactured by members of the group is presented discussing the influence of the EDM process on the machined tooling components and the consequent influence on the replication process.
Feasibility study for microfluidic separation device for biological fluids
Imego AB

Denator AB
Yes
The study requested is a preparation for a possible research and development project of a product that can perform fast separation and inactivation of biological fluids. Proteins, peptides and metabolites are rapidly degraded after extraction, which causes large problems for both academic and industrial protein research. In this study, Imego will investigate the feasibility of fabricating low-cost glass and polymer chips that combine microfluidic separation with Denator’s proprietary preservation technology.
