FDM 3D Printing (Fused Deposition Modeling)

How it works

1. Filament is fed through a heated nozzle that deposits beads along slice paths.
2. The build plate or toolpath strategy supports overhangs with soluble or breakaway structures.
3. Layers fuse together as they cool; chamber heating improves ABS and nylon performance.
4. Supports are removed and parts can be sanded, tapped, or bonded.

Key advantages

• Lowest cost entry for large, simple geometry and proof-of-concept models
• Wide material choice from PLA to ABS, PETG, PC, and carbon-filled blends
• Quick iteration cycles for jigs and one-off factory aids
• Easy to combine with inserts, threads, and adhesive assembly

Typical applications

• Early form-and-fit prototypes
• Manufacturing aids, brackets, and sensor mounts
• Large architectural or exhibition models
• Educational and maker projects requiring fast turnaround

Design tips

• Orient cosmetic surfaces away from support interfaces when possible.
• Use fillets to reduce stress concentrations on load-bearing FDM parts.
• Specify infill density and wall count when mechanical load is critical.
