excelMSCAN Series with SCANahead Technology Process Accelerators for Additive Manufacturing

SCANahead – Innovative Scanner Control High-End Systems for Additive Manufacturing Powder-based 3D printing offers maximum component-design flexibility. Additive manufacturing enables fabrication of modern, lightweight structures, such as used in the automotive and aerospace industries. Industrial laser processing systems for 3D printing have long relied on SCANLAB scan systems to guide the focused laser beam precisely and with high dynamics across a powder bed, thereby melting defined areas. SCANahead Control Boosts Productivity Faster 3D printing throughput is conventionally achieved by utilizing...

High Throughput Thanks to High Acceleration SCANahead control allows scan systems to deliver full acceleration independent of the scan speeds (i.e. with minimum acceleration duration t a ). The galvos‘ dynamic performance potential is optimally utilized. LASER-OFF LASER-ON The rapid accelerations sharply shorten acceleration periods and braking periods. This significantly reduces the time during which the laser remains switched off at each hatch line (see diagram 1). This cuts process time and also boosts productivity, without requiring changes to process parameters (process speed, laser power...
