Laser engravers often advertise top speeds like 1,000 mm/s or 2,000 mm/s, but those values rarely reflect real engraving performance. This article explains the difference between advertised maximum speed, raster speed, vector speed, and real-time acceleration.
Maximum speed is a theoretical number — the laser head’s top motion speed without engraving complexity. In real applications, precision and material response reduce that value significantly.
Raster engraving scans the head back and forth like a printer. Actual speed depends on how fast the head can accelerate and decelerate at the start and end of each line. Acceleration, not just speed, determines output efficiency.
Vector engraving follows defined paths and slows down at every curve or corner to maintain accuracy. A circle cuts faster than a square at the same speed because it has fewer sharp turns.
Acceleration defines how quickly the head reaches working speed. Higher acceleration = faster completion and better precision, avoiding overburns at corners.
Machines with higher acceleration outperform those with only high top speeds in most real engraving jobs. Look for acceleration rate (mm/s²), review real test results, and check engraving consistency.
