Fused Deposition Modeling (FDM)

 Fused Deposition Modeling (FDM) is a prevalent 3D printing method, employing melted thermoplastic filaments to create precise layered objects, offering versatility across industries for producing prototypes and functional parts due to its affordability and customization options with various materials.

Stereolithography (SLA) is a precise 3D printing technique using lasers to solidify liquid resin layer by layer, perfect for intricate designs and prototypes, albeit limited by slower printing for larger objects, higher costs, and the need for post-processing to remove supports and refine surfaces.

 Selective Laser Sintering (SLS) is an additive manufacturing technique that uses a laser to fuse powdered materials, crafting complex 3D objects. It produces durable, intricate parts without support structures. Though costly with surface roughness, SLS serves diverse industries like automotive and aerospace, excelling in intricate prototypes and end-use parts.
