  1. What is Direct Metal Laser Sintering (DMLS) used for in product development?

    Answer: Fusing metal powder with a laser to create fully dense metal parts used in aerospace and medical devices

    DMLS sinters metal powder layer by layer to create fully dense, production-grade metal components with complex internal geometries.

  2. What is 'slicing software' in the 3D printing workflow?

    Answer: Software that converts a 3D model into printer instructions (G-code) by slicing it into layers

    Slicing software like Cura or PrusaSlicer translates a 3D model into machine-readable G-code by defining layer-by-layer toolpaths, settings, and support structures.

  3. What is 'warping' in FDM 3D printing and how is it prevented?

    Answer: Warping is when corners lift from the build plate due to cooling shrinkage; it is prevented with a heated bed and proper bed adhesion

    Warping occurs when differential cooling causes printed material to contract and pull away from the build surface, prevented by heated beds, enclosures, and adhesives.

  4. What does 'overhanging geometry' mean in the context of 3D printing design for manufacturability?

    Answer: Surfaces that extend outward at angles greater than about 45 degrees from vertical, requiring support structures or redesign

    Overhangs beyond roughly 45 degrees from vertical lack underlying material to print on, requiring either redesigning the geometry or adding support material.

  5. What is the purpose of a 'raft' in 3D printing?

    Answer: A flat, horizontal structure printed beneath the object to improve bed adhesion and reduce warping

    A raft is a thick, multi-layer base printed under the object that provides a stable, flat surface for adhesion and helps prevent warping on difficult materials.

  6. What is 'Z-offset' calibration in FDM 3D printing?

    Answer: Adjusting the nozzle's distance from the build plate to ensure the first layer is properly squished for adhesion

    Z-offset calibration sets the precise gap between the nozzle and build surface so the first layer adheres properly — too high causes poor adhesion, too low causes clogs.
