Omschrijving
Evonik INFINAM® RG 7100 L
INFINAM® RG 7100 L was specially developed for DLP printers and enables the production of parts with isotropic properties and low moisture absorption. The mechanical properties are comparable to those of an ABS material and the black colored formulation can also be used on high throughput printer systems. The printed parts exhibit fine features such as smooth and glossy surfaces making the new photopolymer ideal for demanding design visualizations.
Unique Properties:
- High impact resistance
- High temperature resistance
- High mechanical resistance
- Very good processability
Applications:
INFINAM® RG 7100 L can also be used in applications such as drones, buckles or automotive parts that require high ductility combined with high impact strength. The printed parts can be machined and remain fracture resistant even when subjected to high forces.
