Why Choose SLS 3D Printing Over FDM 3D Printing

Selective laser sintering (SLS) and fused deposition modeling (FDM) are two types of additive manufacturing (AM), otherwise known as 3D printing. Both are regularly employed for rapid prototyping and low-to-medium-volume production. SLS machines methodically fire a laser to sinter the particles of a polymer-based powder to build parts layer-by-layer. On the other hand, FDM machines melt and extrude a polymer filament through a nozzle, depositing it along a prescribed path to form parts layer by layer. While the two types of AM have many similarities, their differences will determine whether SLS vs. FDM is better for you. The primary distinctions between SLS and FDM lie in their operational processes, post-processing requirements, and accessibility in terms of machine ownership. SLS machines operate by selectively fusing layers from a powder bed, obviating the necessity for dedicated support structures. This unique feature is attributed to the powder base, which also functions as suppor...
