DFAM Standards
Design for Manufacturing
Technical constraints and best practices to ensure your parts are printed with maximum strength and accuracy.
These guidelines primarily apply to FDM (Filament) printing. Resin (SLA) prints allow for significantly tighter tolerances.
Wall Thickness
Minimum thickness for structural integrity
Minimum (FDM)1.0 mm
Recommended1.5 - 2.0 mm
Structural3.0+ mm
* Walls thinner than 1mm may warp or fail. Use ribs for thin features.
Feature Size
Smallest resolvable details
Vertical Holes2.0 mm Ø
Embossed Text3.0 mm H
Engraved Text1.0 mm D
Infill & Strength
Balancing weight vs. durability
10-20% Infill
Prototypes, visual models
30-50% Infill
Functional parts, moderate stress
70-100% Infill
High-stress, structural parts
Orientation
Anisotropy and layer lines
- Z-Axis Weakness: Parts are weakest along the vertical axis (layer adhesion).
- Support Reduction: Orient parts to minimize overhangs and supports.
- Surface Quality: Top-facing surfaces will have the smoothest finish.
