Safety

CAUTION: IMPORTANT SAFETY INSTRUCTIONS – READ AND FOLLOW THESE INSTRUCTIONS BEFORE OPERATING THE FIGURE 4 UV CURING UNIT 350.

Introduction

You must be properly trained and have read this manual before operating the Figure 4 UV Curing Unit 350. Also, anyone assisting you must be properly trained. After you are trained, always follow the safety guidelines and procedures in this section before operating the Figure 4 UV Curing Unit 350.

Customer Safety Program

Before using the Figure 4 UV Curing Unit 350, customers must have a safety program in place. The safety program should do the following:

  • Label and point out hazardous equipment, materials, and procedures.
  • Explain what to do in an emergency situation.
  • Provide information about the hazards of equipment and resins in the form of Safety Data Sheets (SDSs). The SDSs are provided with all resins supplied by 3D Systems.

The information in this chapter supplements the customer’s existing safety program. It points out safety considerations that specifically concern the Figure 4 UV Curing Unit 350.

Levels of User

WARNING: DO NOT ATTEMPT TO PERFORM ANY PROCEDURES DESCRIBED IN THIS MANUAL UNLESS YOU HAVE READ THROUGH THE ENTIRE MANUAL FIRST.

 

There are two levels of users of the Figure 4 UV Curing Unit 350, based on the amount and type of training the user has received. The two levels of users (operators and certified service personnel), are described below.

Operator

Operators are trained to operate the system and perform all the necessary tasks to post-cure a part and perform basic preventative maintenance as outlined in this manual.

Certified Service Personnel

Certified service personnel are those who have completed the 3D Systems service training package and are certified to perform service tasks on the machine. Certification may occur at various levels, and certified service personnel should only perform tasks they are authorized and certified to complete.

Safety Design Features in the Figure 4 UV Curing Unit 350

The following design features are provided to reduce potentially hazardous operating conditions:

WARNING: If any of the following safety features fails, your actions may be all that will prevent potentially hazardous operating conditions.

WARNING: if the UV Curing Unit 350 is used in a manner not specified by 3D Systems in this manual, the protection provided by the equipment may be impaired.

 

  • Safety switches behind the Figure 4 UV Curing Unit 350 process-chamber lid is intended to prevent accidental exposure of the user to the UV light. The UV lamps will shut off if the lid is opened during operation.
  • The design of the curing chamber is intended to prevent the UV light from being aimed outside the area of the chamber. Only the metal case surrounding the chamber emits UV radiation.
  • A carbon filter and a fan aid in controlling potential odors that result from the curing process.
  • The Figure 4 UV Curing Unit 350 is currently under UL evaluation for UV exposure.

Safety Symbols and Definitions

The following are safety symbols that are common to 3D Systems guides. Some or all of these symbols may appear in this guide and/or in other Figure 4 UV Curing Unit 350 documentation.

CAUTION: Indicates the possibility of loss of data or damage to equipment.

WARNING: Indicates the possibility of injury or death to personnel.

ELECTRICAL SHOCK HAZARD: High voltage electricity is accessible in the vicinity of this sign or behind the access panel. High voltage can cause severe burns or death, as well as fires. Access panels are for service only and should be opened only by certified service personnel or trained maintenance personnel.

UV RADIATION HAZARD: Invisible UV radiation is accessible in the vicinity of this sign or behind the panel. Radiation can cause eye injury or blindness, burn injury and/or fire. Access panels are for service only and should be opened only by certified service personnel.

HARMFUL IRRITANT WARNING: Indicates that skin or eye irritation could result while exposed to a chemical composition

EYE PROTECTION: Indicates the need for eye protection.

WEAR GLOVES: Wear the appropriate gloves when required. For example, when touching surfaces that may contain or have been exposed to materials, wear nitrile gloves. Heat gloves are necessary when touching surfaces that may be hot to ensure burns don’t occur.

PINCH POINT: Indicates a pinch point hazard that could cause personal injury.
