DFM (Design for Manufacturing)
Design for Manufacturing (DFM) is the engineering practice of designing parts and products so they can be efficiently and cost-effectively manufactured at scale, minimising production issues before tooling or production begins.
In Practice
In 3D printing and rapid prototyping, DFM means designing parts with appropriate wall thicknesses, draft angles, support-free geometries, and material-appropriate tolerances. A part that prints beautifully as a prototype may be impossible to injection-mould without redesign. Applying DFM principles during the prototyping phase — not after — saves hardware startups $10,000–50,000 in tooling revisions. FindNStart's design audit service evaluates your STL/STEP files for DFM readiness before production commitment.

The build plate (also called print bed or build platform) is the flat, heated surface on which a 3D printer deposits material layer by layer to construct a part.
Layer adhesion is the bond strength between consecutive deposited layers in a 3D printed part, determining the part's structural integrity in the Z-axis (vertical) direction.
Fused Deposition Modeling (FDM), also called Fused Filament Fabrication (FFF), is a 3D printing process that builds parts by extruding melted thermoplastic filament through a heated nozzle, depositing it layer by layer.
