When most people think of 3D printing, they picture a process akin to fused deposition modeling (FDM), which is known for its widespread use. Despite its popularity, there's a common misconception that FDM 3D printing is suitable only for creating simple prototypes, proof-of-concept models, and basic prototyping projects, largely due to its affordable materials and lower cost. In reality, this technology is capable of more demanding applications, including producing parts for the automotive and aerospace industries.
It’s easier to understand FDM's capabilities when it’s comparedto other 3D printing technologies. Continue reading to learn how FDM 3D printing stands up to other methods in additive manufacturing.
An in-depth look at the process
Fused deposition modeling, also known as fused filament fabrication (FFF), creates parts by melting and extruding a thermoplastic filament, such as PLA or ABS. The printer's nozzle deposits the melted filament layer by layer in the build chamber until the part is fully formed.
Historically, FDM was considered the least accurate and had the lowest resolution among 3D printing technologies, especially when compared to selective laser sintering (SLS) and stereolithography (SLA). This resulted in parts with visible layer lines and inaccuracies in complex features, leading some engineers to opt against using FDM for intricate or complex designs.
However, advancements have been made to improve the finish of FDM 3D-printed parts. Mechanical and chemical post-processing techniques can now smooth out these parts, enhancing their appearance and feel. Additionally, modern industrial-grade FDM 3D printers support the use of soluble supports, which helps overcome previous limitations by allowing for more complex designs with improved accuracy.
Materials
FDM 3D printing can create prototypes and end-use parts from a wide range of thermoplastic filaments, such as:
Generic resin: Dichromatic or monochrome PLARigid resin: White ABS or PCToughness Resin 95A: White TPUAnti-UV: White ASA
Why choose FDM over other technologies?
Fused deposition modeling technology has greatly improved since it was first invented. Today, the availability of high-performance plastics makes it possible to use FDM for parts that have to stand up to the elements. Moreover, FDM can accommodate large build volumes without compromising turnaround times and complex geometries.
