EnvisionTEC, a leading global manufacturer of desktop and full-production 3D printers and materials, unveils line of research-grade materials for its 3D-Bioplotter Series printers as well as three new engineering-grade materials for industrial customers. In all, EnvisionTEC now offers more than 170 materials, which come in a range of functions and colors.
EnvisionTEC’s growing material R&D team is led by Dr. Vadim Nazarov, who studied photochemistry with renowned 3D printing expert Jean-Claude André of the French National Center for Scientific Research before joining EnvisionTEC in 2003.
The three new industrial materials are available for users of EnvisionTEC’s Desktop, Perfactory and 3SP printers. The company’s 3SP technology, first unveiled in 2013, offers a fast and unique vat photopolymerization method in large build envelopes up to 18 x 18 x 18 inches.
The new materials include:
E-CE, a stiff, heat-resistant material with chemical resistance. It is comparable to other cyan-type ester materials in the 3D printing market. With a heat deflection temperature of 170°C, E-CE suits industrial applications that require thermal stability such as electronics encasements and under-the-hood parts. Compatible machines: Desktop, Perfactory.
E-Poxy, a partially biosourced, tough, dual-cure material that delivers strong, thin-walled final products. E-Poxy offers a good relationship between flexibility, hardness and heat resistance that also suits connectors. Compatible machines: Desktop, Perfactory.
E-Model Flex, a highly accurate modeling material with improved elongation at break that will be offered in both green and black. Compatible machines: Desktop, Perfactory. 3SP.
New Bioprinter materials
Silicone TG, a technical grade silicone for building soft implant surgical models such as noses and breasts at room temperature. This RTV-1 silicone, available in transparent, black or in shades of gray, will cure by itself within a few hours under the influence of atmospheric moisture. It displays low shrinkage, a medium hardness of about 20 Shore and is odorless during printing. Suitable for relatively large parts made on the 3D-Bioplotter.
PCL 45K RG, a Research Grade (RG) polycaprolactone (PCL) for tissue engineering applications. Mechanical stability of PCL objects are controlled by the porosity design of the part. A candidate for bone and cartilage regeneration, as well as drug delivery. The surface erosion of the material allows controlled release of additives during the 1-3 year degradation period of the fabricated parts.
LT Support RG, a low-temperature research grade saccharide material derived from cellulose that is used for sacrificial supports. It can be processed as a hydrogel and dissolved in distilled water after the support for the 3D build project is no longer needed. Biocompatible and cell friendly, this material does not negatively affect final object’s biological properties. Processing temperature is 23°C.
HT Support RG, a high-temperature research grade sugar derivative material that is also used a sacrificial support material. This biocompatible material can be dissolved in distilled water at room temperature within a few minutes. Processing temperature is 150°C.
