Verne Additive Manufacturing Labs is presenting a new SLS 3D printer at Formnext 2024 that can process high-temperature plastics such as PEKK. The STROM printer reaches temperatures of up to 380 degrees Celsius.
Processing PEKK was previously considered a technical challenge in the SLS process. Standard systems usually work at around 200 degrees Celsius. The new system aims to make material processing more cost-effective and at the same time meet the high temperature requirements.
The printer has an installation space of 220 x 250 x 400 millimeters. The system uses either a 40-watt CO2 laser or a fiber laser configuration. An infrared camera and AI-supported image analysis, which monitors each print layer, are used for process monitoring.
PEKK is particularly suitable as a metal substitute as it has a favorable strength-to-weight ratio. The material is also characterized by its chemical and temperature resistance. The printer also processes standard SLS powders such as PA12 and PA11.
In addition to the STROM system, Spengler, the parent company of Verne AM, is also presenting the Super VibroBlast. This post-processing system has a capacity of 120 liters and automatically removes powder residues from SLS, MJF or SLM parts.
Both systems are part of an end-to-end production chain. In addition to the 3D printer, this also includes an automatic powder management system (SM-1), a transport system (trolley) and surface treatment solutions (SurfPro).
