LaserSafe Workshop Entrance Sign (Multi-Color PLA)

Need a clear warning sign for your workshop entrance? This 3D-printed laser safety sign is designed for use with diode, CO₂, and fiber lasers to alert anyone entering that a laser is in operation.

xTool Class 4 lasers are the highest risk, with output power above 500 mW or 10 J/cm² for pulsed lasers. They can seriously harm eyes and skin from direct, reflected, or scattered beams, and may start fires. Safe use requires protective eyewear, controlled areas, operator training, and written SOPs to prevent injury and environmental hazards.

This warning sign is suitable for both professional and private workshop environments where preventing eye and skin exposure to hazardous laser radiation is essential.

• Designed as a multipart model, so you can easily assign different colors to each element directly in your slicer for maximum contrast and readability.
• Recommended print material: PLA for easy, clean results; PETG also works very well if you prefer a tougher, more temperature-resistant sign with higher durability.

The sample in the photos was printed in PLA and delivers a crisp, professional-looking finish that stands up to everyday workshop conditions.
