Introduction to the Two-Step Process in 3D Printing
At its core, FDM 3D printing has traditionally been limited by the use of single-filament extrusion. This constraint means that while you can print complex shapes, the material properties remain uniform throughout the part. However, researchers from Seoul National University have broken these boundaries by developing a two-step process that integrates multiple materials, enabling the creation of parts with gradient material properties.
A New Era in Multi-Material FDM 3D Printing
The innovative process, known as blended FDM (b-FDM), uses digital material (DM) filaments. These filaments are created by depositing different base materials layer by layer. This technique offers an unprecedented level of control over material composition and distribution within a filament, making it possible to tailor properties such as strength, conductivity, and color in specific sections of a printed part.
Understanding Blended FDM (b-FDM) Technology
b-FDM technology essentially transforms the way we think about material properties in FDM 3D printing.
What is Blended FDM?
Blended FDM (b-FDM) stands for “blended Fused Deposition Modeling.” It’s a method that overcomes the traditional limitations of single-filament extrusion by creating digital material (DM) filaments composed of various base materials deposited layer by layer.
The Magic of Digital Material Filaments
Digital material filaments are at the heart of b-FDM technology. By layering different base materials, you can achieve precise control over the material composition within the filament. This enables you to create printed parts with significant variations in properties, including:
- Strength: Tailor the mechanical strength where it’s most needed.
- Conductivity: Integrate electrically conductive paths.
- Color: Create intricate, multi-colored designs with fewer filaments.

How b-FDM Technology Works
The two-step process developed by the researchers is key to understanding b-FDM.
Step 1: Creating Digital Material Filaments
The first step involves the creation of digital material filaments. Different base materials are precisely deposited layer by layer, forming a composite filament that can exhibit varied properties in specific sections.
Step 2: FDM 3D Printing
The second step is the actual FDM 3D printing process. The digital material filaments are fed into a standard FDM printer, which extrudes them according to the design specifications, ensuring that each printed layer benefits from the specific material properties integrated within the filament.
| Step | Description |
|---|---|
| Step 1: Filament Creation | Layering different base materials to form digital material (DM) filaments. |
| Step 2: 3D Printing | Using FDM 3D printing to extrude the composite filaments into the desired shape and functionality. |
