CAD Design
From idea to a production-ready 3D model
From concept to precise 3D models engineered for manufacturability. You bring the idea; we engineer the design and hand over files ready for 3D printing, vacuum casting or production tooling.

Design considerations
Accuracy, functionality, manufacturability
Precise 3D models engineered for manufacturability.
Geometry
06- Overall dimensions and complex shapes
- Contours, drafts, fillets and chamfers
- Wall thickness, ribs, bosses and gussets
- 3D surfaces and freeform geometry
- Parametric and editable models
- Optimized for weight and performance
Functional requirements
06- Component interfaces and assembly clearances
- Moving parts and kinematic constraints
- Fasteners, mounting points and fixtures
- Load, stress and durability requirements
- Ergonomics and user interaction
- Environmental conditions: temperature, chemical, outdoor
Material & process
06- Material selection for FDM, SLA, SLS, MJF, vacuum casting or injection molding
- Process-specific design guidelines
- Minimum and maximum wall thickness
- Draft angles, undercuts and parting lines
- Shrinkage and dimensional accuracy
- Surface finish and post-processing needs
Validation & optimization
05- Design review and tolerance analysis
- Interference and collision checks
- Motion simulation and assembly fit
- Structural analysis (FEA) where needed
- Iteration to optimize cost, weight and performance
