Evonik will launch three new photosensitive polymers for 3D printing

Evonik launched three new INFINAM photosensitive polymers for industrial 3D printing, expanding the photosensitive resin product line launched last year. These products are used in common UV curing 3D printing processes, such as SLA or DLP. Evonik said that in less than two years, the company had launched a total of seven new formulations of photosensitive polymers, "making the materials in the additive manufacturing field more diversified".

Three new photosensitive polymers are:

● INFINAM RG 2000L
● INFINAM RG 7100L
● INFINAM TI 5400L

INFINAM RG 2000 L is a photosensitive resin used in the eyewear industry. Evonik said that this transparent liquid can be quickly solidified and easily processed. The company said that its low yellowing index is not only attractive for spectacle frames made of additives, but also suitable for applications such as microfluidic reactors or transparent high-end models to observe the internal work of complex components, even under long-term ultraviolet radiation.

RG 2000 L's light transmission also opens up further applications, such as lenses, light guides and lampshades.

INFINAM RG 7100 L is specially developed for DLP printers and can be used to produce parts with isotropy and low moisture absorption. Evonik said that its mechanical properties are equivalent to ABS materials, and the black formula can be used in high-throughput printer systems.

Evonik said that the RG 7100 L has fine characteristics, such as smooth and shiny surfaces, making it an ideal choice for highly demanding visual design. It can also be applied to unmanned aerial vehicles, buckles or automotive parts that require high ductility and high impact strength. The company said that these parts can be machined to maintain fracture resistance even when subjected to large forces.

INFINAM TI 5400 L is an example focusing on product development. Evonik said that it was responding to the requirements of customers, especially those in Asia, to provide limited edition designers in the toy market with resins similar to PVC.

Evonik said that white materials are very suitable for objects with high details and excellent surface quality. According to the company, the surface quality of this material is almost the same as that of similar injection molded parts. It combines "excellent" impact strength and high elongation at break, and shows lasting thermal mechanical properties.
The director of Evonik R&D and innovative additive manufacturing said: "As one of Evonik's six major innovation growth areas, our investment in developing new formulas or further developing existing products is higher than the industry average. The broad material prospect is the basis for permanently establishing 3D printing as a large-scale industrial manufacturing technology."

Evonik will show its new products at the Formnext 2022 exhibition in Frankfurt later this month.

Evonik also recently introduced a new class of INFINAM polyamide 12 material, which can significantly reduce carbon dioxide emissions
