3D printing materials
Materials for demanding tasks
At Formnext, Lehvoss will be showcasing 3D printing materials for demanding tasks. For example, Luvocom 3F PEI 50236 GY, which meets the EN45545-2 standard, which is particularly popular in the railroad industry. The material, based on polyetherimide (PEI), already fulfills the EN45545-2 R1 HL3 certification for 3D-printed samples that are only 2 mm thick. According to the company, the test specimens made from Luvocom 3F PEI 50236 GY achieved unprecedented test values, positioning the material as one of the best in its class for web applications. This enables the use of 3D-printed parts in sensitive applications in rail vehicles. The material is gray in color. This eliminates the need for a base coat of paint on components and improves weather resistance and UV resistance.
The production of mechanically resilient, temperature- and chemical-resistant molds for laminated components made of GFRP and CFRP plastics using 3D printing processes is becoming increasingly popular. The tools produced in this way for laminating prototypes, batch size 1 or small series represent a technically high-quality and economical alternative to conventional mold making, as complex and time-consuming roughing processes are replaced by near-net-shape 3D printing and the directly downstream fine finishing process. Lehvoss will be presenting a wide range of customized 3D printing materials for this area. These also enable the use of sophisticated resin systems, such as polyester or epoxy resin, which are used for sophisticated carbon fiber laminates. In particular, the resin systems differ in their chemical reactivity and the required consolidation temperatures and pressures.
