Lantek Expert v43 is the latest iteration of Lantek’s flagship CAD/CAM nesting software, released in September 2023 as part of the broader Lantek Global Release v43. Developed by Lantek (a leading provider of software solutions for the sheet metal and metal cutting industry), it automates CNC programming for cutting and punching machines, optimizing material usage and production efficiency. This version introduces over 80 enhancements across Lantek’s product suite (including Expert, Flex3D, Bend, MES, and Integra), with a strong emphasis on process automation, traceability, flexibility, and digital transformation. It’s designed for manufacturers using technologies like laser, plasma, oxy-fuel, water jet, and punching, supporting machines from brands such as Amada, Bystronic, Trumpf, and many others.
Lantek Expert v43 is trusted by over 30,000 customers worldwide and is particularly valued for its advanced nesting algorithms, which reduce waste and shorten machining times. As of October 2025, v43 remains the current major release, with ongoing minor updates available to users with active maintenance contracts.
