Building the Future: An Overview of Fused Deposition Modeling (FDM) in 3D Printing Technology

Fused deposition modeling is a versatile additive manufacturing technology that can build parts with complex geometries with support structures for overhanging features. FDM 3D printing extrudes a plastic filament through a nozzle and lays it down the build chamber layer by layer to create your custom part. The process can involve a wide range of materials, allowing you to use FDM for low-volume end-use production or quick prototyping.

The reasonable cost, vast material selection, and accuracy make fused deposition modeling among the widely used additive manufacturing methods. Keep reading to learn more about FDM.

How it works

FDM 3D printing uses liquefied thermoplastic filaments, which are then re-solidified to a custom shape based on your CAD model. The printer consists of two spools: one for the support structures and the other for the build material. Here is a quick look at the process:

• Step 1: After inputting the CAD data, the solid build material filament is heated to become molten liquid.
• Step 2: The material goes to the foam build platform as a layer via an extrusion nozzle, which moves in the directions defined by the CAD. The process is repeated until the part is complete. Support structures are provided for any overhangs to prevent bending and warping. The supports can be similar to your part’s material, or you may pick another.
• Step 3: Any supports used during printing are removed after completing the part.

Materials for FDM

FDM 3D printing typically uses rigid plastics, such as nylon, ABS, and polycarbonate. Some service providers also offer performance plastics like Ultem. Most materials are ideal for custom functional bits, enclosures, and housings. Fused deposition modeling ensures high accuracy, allowing you to build detailed end-use parts with robust materials.

Why FDM?

Certain factors make FDM 3D printing popular and widely used, even in the near future. It is cost-effective, can print in color, reduces material waste, and ensures quick turnaround. Just be sure to work with a reputable service provider to experience these advantages.
