Fused Deposition Modeling (FDM) 3D Printing Services

Our industrial FDM 3D printing machines offer improved repeatability for industrial, aerospace, and medical prototyping and production. Today, there are hundreds of FDM and FFF printers available in different sizes, materials, and application capabilities.

Like many additive manufacturing technologies, fused deposition modeling machines can operate continuously, allowing efficient production and quick turnarounds—often in as little as one to two days.

FDM 3D Printing Process

The FDM 3D printing process builds a component from a 3D CAD model using thermoplastic filament. The filament is loaded into the machine, which reads the sliced layers from the CAD model.

The system heats the thermoplastic and support material, then deposits them through a nozzle using a 3-axis motion system. Material is deposited layer by layer until the part is fully formed.

This method allows engineers to create durable parts with complex geometries using real thermoplastic materials.

These printers can produce parts at varying layer heights depending on material selection and performance requirements, such as surface finish, cost, and structural strength.

Industrial FDM additive manufacturing systems are ideal for building large parts or batches of smaller components that require consistent, repeatable production and reliable tolerances.

Very large parts can be printed in sections and assembled during post-processing.

Desktop 3D printers typically have smaller build volumes around 11” × 7” × 6” (280 × 175 × 150 mm) and are widely used by designers, engineers, educators, and makers.

FDM Design & Build Guidelines

Each additive manufacturing process has its own design considerations. Below are common guidelines for fused deposition modeling 3D printing:

• FDM Build Layers
  • 0.007” layers: Best surface finish, accuracy, detail, and strength, but increases cost and build time (Ultem not available).
  • 0.010” layers: Best balance of surface finish, detail, strength, and cost.
  • 0.013” layers: Best for fast, low-cost parts, but reduced finish and accuracy.

• Additional Design Guidelines
• Minimum Wall Thickness & Features: 0.71–1.32 mm (0.028”–0.052”) depending on layers
• Standard Finish: Level 1 support removal finish
• Standard Lead Time: 1–3 days
• Tolerances: ±0.005” for the first inch, then ±0.002” per inch thereafter
• Inserts: Installed during post-processing with heat stake or adhesives
• Holes: Drill, ream, and tap after printing

Frequently Asked Questions

Q: What are FDM 3D printing services?
A: FDM (Fused Deposition Modeling) 3D printing services use a thermoplastic filament that is heated and extruded layer by layer to build parts. This additive manufacturing method is widely used for producing functional prototypes, concept models, and durable components with good material strength.

Q: How does FDM additive manufacturing differ from other 3D printing technologies?
A: FDM differs from other 3D printing methods like stereolithography or HP Multi Jet Fusion by using melted thermoplastic filament instead of resin or powder.

Q: What types of parts can be made with fused deposition modeling?
A: FDM can produce a variety of parts including functional prototypes, fit‑form testing models, jigs and fixtures, housings, and low‑volume production components. It is especially useful when strong, durable parts are needed quickly and economically.
