A talk on disruptive technology, market figures, technologies in additive manufacturing and UV=LED in additive manufacturing. As well as details on various testing results.

The 3D UV additive production system employs a photopolymerization to build up thin layers of a part of 3D-object.  We developed a one-dimensional mathematical model of the photopolymerization kinetics to elucidate the conversion of monomer and shrinkage.  The photopolymerization is likely inhibited by the oxygen from air.  An un-rea

The process of two-photon induced polymerization (2PP) enables free-form stereolithography with a resolution in the sub-micrometre range. Thus the production of 3D-printed parts containing arbitrary microscopic features, like photonic crystals, optical waveguides and microelectronic components, is possible. Since aqueous media and biological specim

In just the past few years, advances in UV LED technology has been able to provide peak output powers commensurate with and greatly exceeding microwave lamps. Thus, the well-known benefits of an LED-based UV curing system (instant on-off, Hg free, longer life, lower cost of ownership, etc…) may be fully realized. However, the proper combination of

Formulation modification has enabled the use of an increasing number of UV LED curable adhesives, inks, and coatings for commercial applications.  Among the available formulations, the variation in curing performance is quite large and surface cure remains the biggest challenge to overcome with LED curing.  The curing performance, specifi
