Durable Material Selection in Industrial 3D Printing

With the advancement of manufacturing technologies, 3D printing has expanded its use across industrial applications—from rapid prototyping to end-product manufacturing. However, the success of this technology depends not only on the printer’s specifications but also on the durability and performance of the materials used. In this article, we focus on the scientific and practical criteria for selecting the most suitable and durable materials for industrial 3D printing.

What Is 3D Printing?

3D printing is an additive manufacturing technology that transforms a digital model into a physical object by building it layer by layer. It is widely used in industries such as automotive, aerospace, healthcare, and defense. The ability to produce complex and low-volume parts with cost efficiency and speed has significantly increased the appeal of this technology. However, material selection plays a crucial role in ensuring the functionality and durability of the final product.

What Are Common 3D Printing Materials?

Materials used in industrial 3D printing must withstand high temperatures, chemicals, and mechanical loads. When selecting a material, the following criteria should be considered:

• Tensile and impact strength
  
• Thermal resistance
  
• Chemical durability
  
• Wear and friction performance
  
• Surface quality and post-processing compatibility
  

Here are some of the most commonly used materials:

• ABS (Acrylonitrile Butadiene Styrene): Suitable for parts requiring high impact resistance and mechanical strength.
  
• Nylon (PA): Known for its flexibility, wear resistance, and low friction coefficient.
  
• PETG: Popular due to its chemical resistance and ease of processing.
  
• PEEK: An advanced engineering plastic used in aerospace and medical fields with high temperature and radiation resistance.
  
• Polycarbonate: Ideal for applications requiring both durability and transparency.
  

How to Select 3D Printer Materials for Industrial Use

When selecting 3D printer materials, it’s not enough to rely solely on technical datasheets. Variables such as application area, environmental conditions, and usage frequency must also be analyzed. For example:

• For high-temperature parts, PEEK or ULTEM polymers are ideal.
  
• For moving parts exposed to friction, nylon or carbon fiber-filled filaments are recommended.
  
• For food-contact parts, FDA-approved PETG is suitable (source: FDA.gov).
  

Some engineering materials may require post-processing such as heat treatment or coating. Therefore, compatibility with post-production processes must be considered during the design stage.

How to Compare 3D Printing Materials in Terms of Durability

Choosing the right material for industrial 3D printing requires engineering-level analysis. Key comparison metrics include:

• Tensile Strength
  
• Young’s Modulus (Elasticity)
  
• Glass Transition Temperature
  
• Density and Specific Gravity
  
• Layer Adhesion Strength
  

For instance, PEEK has a tensile strength of approximately 90–100 MPa, while ABS averages around 40 MPa. PEEK can operate at temperatures up to 250°C, whereas PLA may deform at just 60°C (source: MatWeb.com).

Hence, regardless of the product’s purpose, mechanical and thermal performance comparisons must be made based on scientific data.

Which Industries Use 3D Printing Materials?

3D printer materials are utilized across multiple industries in the following ways:

1. Automotive Industry

• Prototyping
  
• Functional testing components
  
• Lightweight and heat-resistant parts
  

2. Aerospace & Defense

• High-strength structural parts
