  1. What does FDM stand for in 3D printing?

    Answer: Fused Deposition Modeling

    FDM (Fused Deposition Modeling) is an additive manufacturing process that extrudes melted thermoplastic filament layer by layer to build a 3D object.

  2. What is stereolithography (SLA) 3D printing?

    Answer: A resin-based process that uses UV laser light to cure photopolymer resin layer by layer

    SLA 3D printing uses a UV laser to selectively cure liquid photopolymer resin, producing parts with very high detail and smooth surface finish.

  3. What is 'support material' in 3D printing and why is it needed?

    Answer: Temporary structures printed beneath overhanging geometry to prevent collapse during printing

    Support material holds up overhanging features that would otherwise sag or collapse since 3D printing builds layer by layer without instantaneous structural support.

  4. What does 'layer resolution' mean in 3D printing?

    Answer: The thickness of each printed layer, which determines vertical detail and surface smoothness

    Layer resolution (layer height) determines how thin each layer is — smaller values produce smoother, more detailed prints but take longer to complete.

  5. What is Selective Laser Sintering (SLS) used for in product development?

    Answer: To fuse powdered nylon or other materials with a laser for strong, functional parts without support structures

    SLS uses a laser to sinter powdered material (typically nylon), producing durable, functional parts with complex geometries and no support structures needed.

  6. What is 'infill' in FDM 3D printing?

    Answer: The internal structure printed inside a solid-looking object to add strength while saving material

    Infill is the internal lattice or pattern printed inside an object, with adjustable density (typically 10-100%) that balances strength and material usage.
