Safety

CAUTION: IMPORTANT SAFETY INSTRUCTIONS – READ AND FOLLOW THESE INSTRUCTIONS BEFORE OPERATING THE FIGURE 4 MODULAR SYSTEM.

Introduction

You must be properly trained and have read this manual before operating the Figure 4 Modular system. 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 Modular.

Customer Safety Program

Before using the Figure 4 Modular, 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 Modular system.

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 Modular, 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 build 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. 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 Modular

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 Figure 4 modular IS USED IN A MANNER NOT SPECIFIED BY 3D SYSTEMS IN THIS MANUAL, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.

  • Safety switches on the Figure 4 Modular upper-chamber door, print platform, resin-tray, and catch tray are intended to prevent accidental exposure of the user to the optical radiation.
  • The design of the projection-based radiation-delivery system is intended to prevent the optical radiation from being aimed outside the area of the process chamber.
  • The orange-acrylic door in front of the process chamber prevents operator exposure to optical radiation emission while observing operation.
  • The Figure 4 Modular system has been evaluated to IEC 62471 and the internal optical radiation source classified as ‘Risk Group 2,’ and does not pose a hazard due to aversion response to bright light or thermal discomfort. Optical radiation is emitted from this product. Eye irritation may result from exposure. Use appropriate shielding.

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 Modular 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.

CAUTION: Possible hazardous optical radiation emitted from the product. Do not stare at operating lamp. May be harmful to the eyes.

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.

Personal Injury Warning: Failure to avoid the pneumatic tension arms may result in personal injury. Avoid the tension arm areas at all times.

HOT SURFACE HAZARD: A hot surface is accessible in the vicinity of this sign or behind the access panel. Avoid contact. Hot surfaces can cause burn injury or fire. Allow surface to cool before touching. Access panels are for service only and should be opened only by certified service personnel or trained maintenance personnel.

NOTE: A note signifies important information but not information of a critical content.

 

Alarms and Warnings

  • If you hear an alarm, or if you see an error, alarm, or warning message on either the Figure 4 Modular Controller or Printer display: clear the alarm, error, or warning message before resuming operation.
  • Displayed error, alarm, or warning messages can result from unsafe practices, such as defeating a safety switch.
