3D printed chainmail has emerged as a modern reinterpretation of ancient flexible armor, leveraging advancements in additive manufacturing technologies. This historical overview explores its origins and technological progress.

Evolution from Traditional Chainmail

Traditional chainmail, made via manual linking of metal rings, dates back to ancient civilizations and was primarily used for protection in combat. The concept has been adapted and transformed by 3D printing, which allows for the creation of intricate, interlocking structures not possible with the manual method. This evolution began with the advent of 3D printing in the 1980s but gained significant traction in the early 21st century as printers became capable of producing finer resolutions and more complex designs.

Basics of 3D Printed Chainmail

3D printed chainmail combines modern manufacturing techniques with ancient armor design principles. It relies on precise engineering to create interlinking rings that form a flexible mesh.

Materials Used

Common Materials:

  • PLA (Polylactic Acid): Popular due to its ease of use and environmentally friendly properties.
  • ABS (Acrylonitrile Butadiene Styrene): Known for its strength and durability.
  • TPU (Thermoplastic Polyurethane): Flexible material, often used for chainmail to mimic the traditional metallic flexibility.

Note: The selection of material affects the chainmail’s properties, such as weight, flexibility, and durability.

Types of 3D Printers

Printer Technologies:

  1. Fused Deposition Modeling (FDM): Widely accessible and commonly used for printing chainmail.
  2. Stereolithography (SLA): Delivers higher resolution prints, beneficial for intricate chainmail designs.
  3. Selective Laser Sintering (SLS): Suitable for strong and flexible prints, but less common due to higher costs.

Each 3D printer type offers different benefits and limitations that should be considered when producing chainmail.

Design Considerations

When designing 3D printed chainmail, it is crucial to consider the configuration of chain link structures, balance flexibility with durability, and ensure the end product is comfortable and manageable in weight.

Chain Link Structures

In 3D printed chainmail, the structure of the chain links is fundamental. They must interlock effectively to mimic the behavior of traditional chainmail. Designers often use torus-shaped links, with a focus on the inner diameter (to ensure proper movement) and the cross-sectional diameter (for strength). For instance, a standard ring might feature:

  • Inner diameter: 5mm
  • Cross-sectional diameter: 1mm

Optimizing these proportions is necessary to maintain integrity.

Flexibility and Durability

Flexibility and durability are two characteristics that should work in tandem. The material choice—such as thermoplastic polyurethane (TPU) or acrylonitrile butadiene styrene (ABS)—affects both. Flexible materials may require thicker link cross-sections for durability, whereas rigid materials might need reduced thickness for flexibility. A common combination might be:

  • Flexible: TPU with 1.2mm thickness
  • Rigid: ABS with 0.8mm thickness

This ensures that the chainmail can withstand stress while remaining functional.

Weight and Comfort

The weight and comfort of the final chainmail product are significant, especially for wearable applications. The design must ensure that the chainmail is not overly heavy, which could impede movement or cause discomfort. For a balance, designers might use a configuration such as:

  • Link volume: 20mm³
  • Material density: 1.2g/cm³
  • Calculated weight per link: approximately 0.024g

Plus, the design’s surface finish and flexibility can contribute to increased comfort during use.

Manufacturing Process

The manufacturing process of 3D printed chainmail involves a series of steps from design to finishing. Each step is critical in producing functional and durable chainmail.

3D Modeling

The first step in creating 3D printed chainmail is to design the individual links using 3D modeling software. The designer must account for the link size, interlocking mechanisms, and overall flexibility. These designs are typically created in software such as Autodesk Fusion 360 or Blender.


After 3D modeling, the next step is slicing the model into thin horizontal layers that can be printed. This is done using a slicing software program, which also generates the G-code that will guide the 3D printer. Key parameters such as layer height, print speed, and fill density are determined at this stage.


3D printing the chainmail follows the slicing stage. Here, the 3D printer uses the G-code to print each link layer by layer. Material choice is important; thermoplastics like PLA, ABS, or TPU are commonly used for their properties that lend strength and flexibility to the chainmail.


Upon completion of printing, the chainmail requires post-processing. This may involve removing support structures, smoothing rough edges, and sometimes annealing the plastic for added strength. Each step ensures the final product meets quality standards and functions as intended.

When examining 3D printed chainmail, several challenges and limitations emerge that must be considered, which include its mechanical properties, production costs, and manufacturing duration.

Strength and Stability Concerns

3D printed chainmail faces skepticism regarding its strength and stability, especially when compared to traditionally forged chainmail. The material choice and layer adhesion are critical factors that affect the final product’s durability. For example, thermoplastic polymers often used in 3D printing may not withstand the same stress levels as metal, potentially leading to deformation or breakage under pressure.

Cost Efficiency

The cost of producing 3D printed chainmail can be higher than conventional methods due to several factors:

  • Material Expenses: High-performance polymers or metals suitable for printing can be expensive.
  • Machine Operation: The use of sophisticated printers and the electricity they consume increases costs.

Time Consumption

3D printing is a time-intensive process, particularly for objects with complex geometries like chainmail. Each link is printed layer by layer, which can extend production time significantly. This slow production speed can limit the feasibility of using 3D printed chainmail in large-scale or time-sensitive applications.
