dc.description.abstract
The versatility of lithography-based 3D-printing technologies led to its establishment in today's
industry. Complex and highly individualized products are possible, though they also hold some
disadvantages. The yielded polymers lack toughness and suffer from overall bad mechanical
performance.
We decided to tackle this problem by utilizing an epoxide-alcohol system within a methacrylate
matrix. The epoxide-alcohol system provides good mechanical performance, while the methacrylate
acts as a scaffold for the 3D-printing process. Combined an IPN is yielded with good printability as
well as good mechanical properties like high toughness.
Each network is optimized separately. For the epoxy-alcohol system, the twist is that we have a
polyaddition reaction, with low reaction speed but good mechanical properties. These properties are
achieved by the high network homogeneity. The low curing speed of the epoxide alcohol system is
circumvented by introducing a radical system that acts as a scaffold and enables printing.
The networks were tested with respect to their (thermo)mechanic behaviour. For this purpose, tensile
tests as well as DMTA measurements were performed. The polymers that seemed most promising
were combined into one IPN and again tested on these properties to yield the best-performing IPN.
For additive manufacturing as a possible application, a dual cure approach was chosen wherein
sequential, semi-orthogonal light-curing was applied. This way fast printing can be combined with
the slowly curing alcohol epoxide system and its benefits for the mechanical properties.
