Fused deposition modeling, or FDM, is a filament-based thermoplastic 3D printing technology that melts and extrudes material layer by layer onto a build plate to create a part.
FDM is the most common 3D printing process, offering efficiency, precision, cost benefits, and durable materials. It also offers the largest variety of materials and colors of any thermoplastic 3D printing process and a large build volume, making it a popular choice for rapid prototyping, production parts, tooling, fixtures, gauges, and much more.
FDM technology was developed by Scott Crump in the 1980s and was later commercialized by his company, Stratasys. It quickly gained popularity in the early 2010s due to its accessibility and low cost compared to other 3D printing technologies.
FDM 3D printing has a diverse range of applications across many industries.
