Fused Deposition Modeling

FDM is a popular 3D printing technology that works by extruding thermoplastic filament through a heated nozzle. The filament is melted and deposited layer by layer to create the desired object. FDM printers typically use materials like PLA (polylactic acid) and is known for their ease of use, affordability, and accessibility.

Resin-based 3D printing, also known stereolithography (SLA) or digital light processing (DLP), utilizes liquid photopolymer resins. This technology employs a light source, such as a laser or a projector, to selectively cure the liquid resin layer by layer. The cured resin solidifies to form the final object. Resin-based printers offer high resolution, intricate details, and smooth surface finishes, making them suitable for producing highly detailed and visually appealing objects. However, resin-based printers can be more expensive and require additional post-processing steps like washing and UV curing to achieve the desired final result.

Selective Laser Sintering 3D printing:

SLS is an additive manufacturing technology that uses a high-powered laser to selectively fuse powdered materials, typically nylon or other polymers. The laser scans and fuses the powdered layers together, creating a solid object. SLS printers do not require support structures since the unused powder acts as a self-supporting material during the printing process. SLS offers excellent mechanical properties, good accuracy, and the ability to create complex geometries and functional prototypes. It is commonly used in industrial applications where durability and strength are crucial.
