What Is FDM 3D Printing?

Fused Deposition Modeling (FDM) Technology works with specialized 3D printers and production-grade thermoplastics to build strong, durable, and dimensionally stable parts with the best accuracy and repeatability of any 3D printing technology.

A typical FDM 3D printer uses polymer-based filament that is forced through a heated nozzle to melt the material and deposit it on the build platform in 2D layers. These layers combine while they are still hot to eventually form a three-dimensional part.

FDM Printing Process

How Does FDM Printing Works?

Layer by layer melted filament material is deposited onto a build platform by an FDM 3D printer until you have a finished part. FDM converts digital design files into physical dimensions by uploading them to the machine itself.

An initial 3D CAD (computer-aided design) model is used in the procedure. The digital model is divided into several slices (layers) using slicing software, which then produces a G-code file for the 3D printer. To create the 3D model, the solid plastic filament is heated, melted, and extruded from a nozzle onto a build plate in layers. Depending on the desired resolution, each layer can range in thickness from 0.1mm to 0.5mm.

Post-Processing for FDM 3D Printing

Several post-processing techniques, such as sanding and polishing, priming and painting, and vapor smoothing, can be used to finish FDM 3D printed objects to a high quality.
