- Free-standing cabinet with stronger built-in exhaust than desktop models
- Rapid Reconfiguration™ tool-free laser source swaps
- Same compact 24"×12" work area as the Desktop Series for shops with limited floor space
Watch out for
- Quote-only pricing through authorized resellers
- Same 24"×12" work area as the much smaller/cheaper Desktop Series — no size advantage

Watch out for

- Same 75W power ceiling as the smaller, cheaper VLS3.75 — the upgrade is size, not power
