Occupational Safety Training for the 3D Printing Industry

1. Overview of the 3D Printing Industry

a. What is the 3D printing industry?

The 3D printing industry, also known as three-dimensional printing, is an emerging technical field in which objects are created by stacking layers of material one by one using 3D printing technologies. Instead of using traditional methods to produce products from molds or cutting from large materials, 3D printing allows the creation of complex objects by printing successive layers of material according to digital designs.

3D printing technology typically uses 3D printers to create objects from 3D model files generated by design software or scanned from an existing object. The 3D printing process starts by dividing the object into thin layers, and then the 3D printer creates the object by printing each layer until completion.

The 3D printing industry has wide-ranging applications across various fields, including manufacturing, healthcare, art, architecture, and education. It enables the production of customized products, prototypes, machine parts, and many other applications that were previously difficult or time-consuming to achieve with traditional methods.

b. Types of machinery in the 3D printing industry

The 3D printing industry uses a range of machines to carry out the printing process and create 3D objects. Here are some common types of machinery used in 3D printing:

• FDM 3D printers (Fused Deposition Modeling): This is the most common 3D printing technology, often used for home and office applications. FDM printers use a thermoplastic filament that is melted and deposited layer by layer to create a 3D object.
• SLA 3D printers (Stereolithography): SLA technology uses light to harden a special liquid, usually photopolymer resin. SLA printers use a light-blocking window to create each layer of a 3D object by projecting light onto the liquid.
• SLS 3D printers (Selective Laser Sintering): SLS technology uses a laser to melt and fuse material particles, usually plastic or metal powder. SLS printers create 3D objects by melting and bonding layers of powder or particle material.
• DLP 3D printers (Digital Light Processing): DLP technology is similar to SLA, but uses a projector to shine light through a layer of photopolymer resin, curing the layer and forming each layer of the 3D object.

c. Typical 3D printing companies in Vietnam

b. Training duration

Initial occupational safety training:

• Total training time is at least 24 hours, including testing time.
• 8 hours of theory on policies and laws on occupational safety and hygiene
• 8 hours of theory on basic knowledge of occupational safety and hygiene
• 4 hours of theory on specialized training content
• 2 hours of practical exercises on specialized training content
• 2 hours of theoretical examination at the end of the course

The training center will divide the schedule into multiple sessions depending on the availability of workers. Typically, there will be 6 sessions over 3 days, provided the company can arrange continuous learning time.

Periodic occupational safety training:

• Before the occupational safety card expires, workers must undergo periodic occupational safety training with a duration of at least 50% of the initial training time.

Explanation: the total time for periodic occupational safety training is at least 12 hours, including testing. After completing the course and passing the exam, workers will have their occupational safety card renewed.

d. Occupational safety card

After completing the occupational safety training and passing the test, workers will be issued a safety card (commonly called a group 3 occupational safety certificate).

The group 3 safety card shows details such as name, date of birth, specific job and work environment, training duration, official stamp, and signature confirming course completion.

According to regulations on issuing safety cards stated in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must stamp and endorse the safety card for the group 3 worker after completing training at the occupational safety training unit and passing the exam.
• If the worker is freelance or temporary and does not have a labor contract, the training unit must stamp and endorse the safety card for the worker after completing the occupational safety training and passing the exam.

3. Identifying Hazards for Workers in the 3D Printing Industry

The 3D printing industry presents several potential hazards for workers. Here are some common hazards that need to be identified and managed in 3D printing:

• Printing materials: Some 3D printing materials, such as thermoplastics (PLA, ABS) or other harmful plastics, may release toxic or allergenic gases when melted or used. Prolonged exposure to these materials can harm the respiratory system and skin. It is essential to use safe materials and ensure proper ventilation during printing.
• Dust and fumes: The 3D printing process can generate dust and fumes from the printing materials, especially during cutting, sanding, or finishing 3D printed products. These dust and fumes can irritate the respiratory system and eyes. Using protective equipment such as masks, safety goggles, and effective ventilation systems is necessary to protect workers’ health.
• Temperature and electrical safety: During 3D printing, printers can generate high temperatures and involve electrical components. Workers must ensure safe operation and supervision of the printing process to avoid burns or electrical hazards.
• Noise: Some 3D printers produce noise during operation, especially when printing large products or moving parts. Noise can cause stress and affect workers’ hearing. Ear protection and compliance with workplace noise regulations are required.
• Work safety and risk management: The 3D printing industry must comply with occupational safety regulations and risk management practices, such as maintaining a safe workspace, arranging materials and machinery safely, and training workers on safety procedures and appropriate personal protective equipment (PPE).

4. Safety Measures for Workers in the 3D Printing Industry

Safety measures are crucial to protect the health and safety of workers in 3D printing. The following safety measures should be implemented:

• Occupational safety training: Provide training for all employees involved in the 3D printing process. Ensure that workers understand potential hazards, safety procedures, use of PPE, and response measures in case of incidents.
• Use of personal protective equipment (PPE): Ensure that workers are fully equipped and properly use PPE such as masks, safety goggles, gloves, ear protection, and protective clothing. Proper PPE helps protect against dust, fumes, noise, and other physical hazards.
• Material management: Use safe 3D printing materials that do not harm health. Read and follow manufacturer safety instructions for material use and handling. Limit exposure to hazardous materials and ensure proper ventilation in the workspace.
• Printing process management: Conduct 3D printing in a safe environment. Ensure printers and related equipment are installed correctly and operate safely. Regularly inspect and maintain machinery to prevent fire hazards or electrical shocks.
• Auxiliary material management: Manage auxiliary materials such as solvents, adhesives, or chemicals used during 3D product finishing. Ensure proper use, safe storage, and compliance with handling and disposal instructions.
• Noise risk management: Assess and control noise levels in the workspace. Ensure workers use appropriate ear protection and implement noise control measures, such as sound isolation or noise reduction devices.
• Safe workspace organization: Arrange the workspace to be clean, organized, and safe. Remove unnecessary materials, ensure safe walkways, provide adequate working and movement space, and follow safety rules for the work area.
• Periodically organize occupational environment monitoring in factories, collect and analyze harmful factors for workers, and adjust measures to reduce risks and prevent occupational diseases.
