How Fused Deposition Modeling (FDM) Printing Works
FDM is a 3D printing technique that uses thermoplastic filament as its material source. The filament is unwound from a spool and pushed into a heated print head, where it melts. The softened material is then extruded through a fine nozzle, forming a thin, continuous bead that creates each layer of the object. After cooling and solidifying, the build platform lowers incrementally to allow the next layer to be printed, repeating the cycle until the final part is complete.
In addition to the main build material, a secondary filament can be deposited simultaneously to create temporary support structures. These supports are later removed either by dissolution or mechanical means once the printing is finished.
FDM parts are recognized for their strength, durability, and dimensional accuracy. At KingStar Mold, we also offer a range of professional post-processing services to tailor the final parts to your specific application needs.

About the Process
Fused Deposition Modeling (FDM) 3D printing is an additive manufacturing process that builds parts layer by layer from a thermoplastic filament. The filament is fed into a heated print head, where it melts and is extruded through a fine nozzle onto the build platform. As each layer is deposited, the material cools and solidifies, forming a strong bond with the previous layer. The build platform gradually moves to accommodate new layers until the complete part is formed. FDM is widely valued for its ability to produce durable, functional prototypes and end-use parts across a range of industries.
Design Guidelines
When designing for FDM 3D printing, it’s important to account for the process’s specific characteristics to ensure successful, high-quality parts. Key considerations include optimizing wall thickness, adding proper draft angles, minimizing unsupported overhangs, and designing with material shrinkage and layer adhesion in mind. By following proven FDM design guidelines, engineers can enhance part strength, dimensional accuracy, and surface quality while reducing the risk of print failures.

Advantages of FDM 3D Printing

Frequently Asked Questions
While FDM 3D printing is highly effective for prototyping and low-volume production, it is typically not used for large-scale mass production due to speed limitations compared to traditional manufacturing methods. However, it is ideal for producing customized parts or small batches.
The duration of the FDM 3D printing process varies depending on the size and complexity of the part. Generally, FDM prints are completed in a matter of hours to days. Larger parts with intricate geometries may take longer to print, while simpler parts can be printed quickly.
We combine industrial-grade equipment, extensive material options, large-format capabilities, and rapid turnaround to deliver high-quality FDM parts tailored to your project needs.
FDM (Fused Deposition Modeling) is a widely used 3D printing technology that builds parts layer by layer by extruding a thermoplastic filament through a heated nozzle. Compared to other additive manufacturing methods like SLA (stereolithography) or SLS (selective laser sintering), FDM is known for its material versatility, cost-effectiveness, and ability to create durable, functional prototypes and end-use parts. Unlike resin-based processes that cure liquid photopolymer or powder-based processes that fuse fine powders, FDM directly melts solid filament, making it cleaner, easier to handle, and ideal for producing larger parts with industrial-grade materials. This process supports a broad range of engineering thermoplastics and is favored for its scalability, strength, and rapid prototyping capabilities across various industries.
