Safety Instructions
The V650 Flex utilizes a 355-nm laser with a maximum output of maximum output of 1.25 kW
@ 30khz at source. Typical usage is at 100khz. Repetition range is single shot to 300khz.
Pulse duration is <35ns. Laser duty cycle is dependent on repetition rate. When the build
chamber access doors are open and the interlocks defeated, Class IV-High Power Laser
visible and invisible radiation exposure is possible. Only authorized personnel should access
the Laser Enclosure, and must be equipped with necessary eye protection.
A Guarding System employs an electromechanical laser shutter that prevents the emission of
laser light. Opening any of the chamber doors, or engaging the E-Stop, blocks the output of the
beam. With the Guarding System enabled, the product qualifies as a Class 1 Laser Product.
This safety feature can be defeated by turning the "Guarding" key switch to the Bypass
position. In this position, all safety features are disabled and exposure to the laser beam is
possible. Anyone operating the machine in the bypassed state should be familiar with Class IV-
High Power Laser safe practices, and take the appropriate precautions.
The laser beam is a fire and safety hazard. Precautions must be taken to prevent accidental
exposure to direct or reflected laser beam. Both diffuse and specula reflections can cause
severe skin or immediate and permanent eye damage. Proper eyewear must be worn at all
times.
A Class 4 high-powered laser system:
•
Is a hazard to the eye or skin from the direct beam
•
May pose a diffuse reflection risk or fire hazard
•
May also produce laser-generated air contaminants (LGAC) and hazardous plasma
radiation
A laser is also used to monitor resin level while building. It is a class II laser (FDA CDRH
21CFR PART1040.10) with a maximum output of 0.95mW. It has a wavelength of 650 nm
visible light.
Resin
Wear Nitrile gloves when handling any system component that has been contaminated with
resin. Prolonged or repeated contact with certain resins can result in allergic reactions.
Caution:
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Note:
By engineering design no laser radiation exceeding Class 1 accessible emission
limits are present or accessible during operation of this laser-based 3D printing
system.
