Materials characterization for stereolithography
| Nome: | Descrição: | Tamanho: | Formato: | |
|---|---|---|---|---|
| Stereolithography is an additive technology that allows the fabrication of three-dimensional macro and micro-parts for industrial and medical applications. By solidifying a liquid photo-sensitive monomer with a laser or UV-light source a polymeric part is built up layer by layer. The use of highly reinforced polymeric systems with metallic or ceramic particles also enables to transform this rapid prototyping technology into a rapid manufacturing one. The quality and fabrication speed of stereolithographic parts strongly depends on the curing kinetics. Therefore it is crucial to optimize the polymeric mixture for a specific application. This research work investigates the curing kinetics of reinforced and non-reinforced unsaturated polyester resins with different photo-initiator concentrations. Two types of particles were considered: tungsten carbide and hydroxyapatite (concentrations of 30 wt%). | 1.73 MB | Adobe PDF |

Stereolithography is an additive technology that allows the fabrication of three-dimensional macro and micro-parts for industrial and medical applications.

The use of highly reinforced polymeric systems with metallic or ceramic particles also enables to transform this rapid prototyping technology into a rapid manufacturing one. The quality and fabrication speed of stereolithographic parts strongly depends on the curing kinetics. Therefore it is crucial to optimize the polymeric mixture for a specific application. This research work investigates the curing kinetics of reinforced and non-reinforced unsaturated polyester resins with different photo-initiator concentrations.
