FDM 3D Printing Basics
What Is FDM 3D Printing?
FDM (Fused Deposition Modeling) is an additive manufacturing process that creates parts by extruding heated thermoplastic filament through a nozzle. Material is deposited layer by layer onto a build platform, gradually forming a three-dimensional component directly from a CAD model.
As the most widely used 3D printing technology, FDM offers low production costs, large build volumes, and access to a broad range of engineering-grade thermoplastics. Professional FDM services provide industrial equipment, certified materials, and engineering support for consistent production quality.

FDM 3D Printing
How FDM Works
From sliced CAD files to heated extrusion nozzles, FDM builds parts layer by layer. We offer engineering-grade materials and support removal services for functional prototypes.
Additive Process
The FDM Process
The process starts by slicing a CAD file into thin layers. The printer heats thermoplastic filament to 200–400°C and extrudes it through a precision nozzle. The build plate lowers after each layer, fusing the plastic into a solid object.
- Starts with: Sliced CAD files (STL/STEP)
- Temperature: 200–400°C extrusion
- Mechanism: Layer-by-layer deposition
Support Structures
Handling Complexity
For overhangs steeper than 45 degrees, the printer deposits temporary support material. This includes breakaway supports or dissolvable materials like PVA. Supports are removed manually or in a solvent bath after printing.
- Use case: Overhangs > 45 degrees
- Types: Breakaway or dissolvable (PVA)
- Finishing: Removed by hand or solvent bath
Part Quality
Mechanical Properties
The result is a solid thermoplastic part with properties matching injection-molded equivalents. Engineering materials like ABS, Nylon, or Polycarbonate yield high-strength parts on enclosed, heated-chamber systems.
- Strength: Matches injection-molded parts
- Materials: ABS, Nylon, Polycarbonate
- Equipment: Enclosed heated-chamber systems

FDM Materials
Materials We Print
Unlike SLA or SLS, FDM prints with dozens of engineering filaments. We offer standard and engineering-grade materials to match performance to your application without overspending.
Standard Thermoplastics
PLA (Polylactic Acid): The easiest material to print. Biodegradable, low odor, and available in the widest color range. Best for visual models, packaging prototypes, and low-stress parts. Not heat-resistant (deforms above 55°C).
PETG: Combines the ease of PLA with the durability of ABS. Chemical-resistant, food-safe, and prints with minimal warping. Ideal for functional prototypes, enclosures, and parts that need some flexibility.
ABS (Acrylonitrile Butadiene Styrene): The workhorse of engineering FDM. Strong, impact-resistant, and heat-tolerant up to 100°C. Requires a heated build chamber to prevent warping. Perfect for functional prototypes, automotive interior parts, and snap-fit assemblies.
ASA (Acrylonitrile Styrene Acrylate): Similar to ABS but with superior UV resistance. Does not yellow or degrade in sunlight, making it the best choice for outdoor applications, marine components, and exterior automotive parts.
Engineering Thermoplastics
Nylon (PA6, PA12): Exceptional toughness, wear resistance, and low friction. Nylon absorbs moisture, which increases flexibility but requires dry storage. Best for gears, bushings, living hinges, and mechanical components.
PC (Polycarbonate): High impact strength, heat resistance up to 138°C, and transparent options available. Ideal for housings, light guides, and parts that must survive drops or impacts.
PC-ABS: A blend that combines PC’s strength with ABS’s processability and print reliability. Common in automotive interiors and consumer electronics.
TPU (Thermoplastic Polyurethane): Flexible and rubber-like, with Shore hardness from 85A to 95A. Prints durable seals, gaskets, grips, and ergonomic components.

FDM Specifications
Build Size & Tolerances
Understanding what FDM can and cannot do helps you design parts that print successfully the first time. Here are the specifications and capabilities for Baetro’s FDM 3D printing service.
Standard vs. Large-Format
| Specification | Standard FDM | Large-Format FDM |
|---|---|---|
| Maximum build size | 350 × 350 × 350 mm | 1,000 × 800 × 500 mm |
| Layer thickness options | 100 μm, 200 μm, 300 μm | 200 μm, 300 μm |
| Standard tolerance | ±0.5% (±0.5 mm) | ±0.5% (±0.5 mm) |
| Minimum wall thickness | 0.8 mm | 1.0 mm |
| Minimum feature size | 0.5 mm | 0.8 mm |
| Max overhang without supports | 45° | 45° |
Tolerance notes: FDM tolerances are percentage-based because thermal expansion and shrinkage scale with part size. For parts under 100 mm, expect dimensional accuracy within ±0.5 mm. Holes tend to print slightly smaller than modeled (typically 0.2–0.5 mm undersized).
Surface Finish & Post-Processing
As-printed FDM parts show visible layer lines with a surface roughness of approximately Ra 250–900 μin. When a smoother finish is required, several post-processing options are available:
- Support removal: Breakaway supports are removed manually. Dissolvable supports (PVA, BASS) are dissolved in water or solvent baths, leaving cleaner surfaces.
- Vapor smoothing: Acetone vapor smoothing for ABS and ASA produces a glossy, injection-molded appearance by slightly melting the outer surface. Reduces roughness by up to 80%.
- Sanding and filling: Progressive sanding from 220 to 600 grit, followed by primer and paint, achieves a smooth, cosmetic finish suitable for presentation models.
- Painting and coating: Acrylic, enamel, or automotive paints adhere well to sanded FDM surfaces. UV-resistant clear coats protect ASA parts from long-term sun exposure.
