EnvisionTEC launches seven new 3D printing materials

E-Poxy engineering-grade material

EnvisionTEC—a USA-based manufacturer of professional-grade 3D printers and materials—has launched seven new 3D printing materials, namely: three engineering-grade materials for its Desktop, Perfactory and 3SP printers; and four medical-grade materials for its 3D-Bioplotter printers. These bring the company's total materials offering to more than 170.

Engineering-grade materials
The new engineering-grade materials have been developed for EnvisionTEC’s industrial customers. They are E-CE, E-Poxy and E-Model Flex.

E-CE is a stiff, heat-resistant material that offers chemical resistance and is comparable to other cyan-type ester materials in the 3D printing market. It has a heat deflection temperature of 170°C and is therefore suitable for applications that require thermal stability such as electronics encasements and under-the-hood parts.

E-Poxy is a partially biosourced, tough, dual-cure material that delivers strong, thin-walled final products. It affords a good relationship between flexibility, hardness and heat resistance, making it suitable for connectors.

E-Model Flex is a highly accurate modeling material that provides excellent elongation at break. It is to be made available in both green and black.

Medical-grade materials
The new medical-grade materials are the first to be produced by EnvisionTEC for its 3D-Bioplotter printers. They are Silicone TG, PCL 45K RG, LT Support RG and HT Support RG.

Silicone TG is a technical grade silicone material for building soft implant surgical models, such as noses and breasts, at room temperature. It displays low shrinkage, a medium hardness of about 20 Shore and has no smell.

PCL 45K RG is a research grade (RG) polycaprolactone (PCL) material for tissue engineering applications. It is especially suitable for bone and cartilage regeneration as well as drug delivery. The surface erosion of the material allows for controlled release of additives during the one to three-year degradation period of the objects.

LT Support RG is a low-temperature RG saccharide material that is used for sacrificial supports. It is biocompatible and cell friendly, so does not negatively affect objects' biological properties. Furthermore, it can be processed as a hydrogel and is dissolvable in distilled water once the supports are no longer required. The processing temperature is 23°C (73.4°F).

HT Support RG is a high-temperature research grade sugar derivative material that is also used for sacrificial supports. It too is biocompatible and can be dissolved in distilled water. The processing temperature is 150°C (302°F).

EnvisionTEC is presenting the materials at RAPID + TCT, in Pittsburgh, USA, on May 8-12, 2017.

Al Siblani, chief executive officer (CEO) of EnvisionTEC, said: ‘These new offerings showcase our commitment to material development as well as our close relationships with customers, who have asked us to develop specific materials for our highly accurate and reliable machines.’
