Validated workflow
The 3Dresyns® Structured Selection Framework (SSF) is an integrated methodology designed to reduce uncertainty in photopolymer additive manufacturing.
Instead of relying on isolated datasheet values, SSF combines mechanical logic, curing behaviour and empirical validation into a reproducible engineering workflow.
Why SSF
Photopolymer performance depends on multiple coupled variables:
- Printer irradiance and optical system
- Exposure strategy and layer thickness
- Post-curing conditions
- Geometry and minimum feature size
- Load mode and application context
SSF structures these variables into a controlled engineering process.
Core pillars
Engineering selection
Based on structural mechanics logic:
Rigidity ∝ E × t³
- Links modulus with geometry
- Prevents brittle overdesign
- Aligns material with real function
Comparative material positioning
Selection across functional resin families using thermoplastic-like behaviour mapping.
- Stiffness range
- Deformation tolerance
- Thermal positioning
- Functional behaviour
Exposure calibration (CRT)
- Exposure reproducibility
- Layer thickness control
- Dimensional predictability
- Cross-printer transferability
Mechanical validation (SMSP)
- Rigidity threshold
- Break thickness
- Printer-specific behaviour
Implementation sequence
- Define application intent
- Select stiffness window
- Position material family
- Calibrate exposure (CRT)
- Verify dimensions
- Diagnose failures if needed
- Validate mechanically (SMSP)
- Implement controlled workflow
Engineering positioning
Design → Material → Process → Validation
SSF transforms photopolymer printing from trial-and-error into a structured engineering system.
Scientific foundations
- Beam mechanics (E × t³)
- Photopolymer cure kinetics
- Dimensional calibration methodologies
- Failure morphology analysis
- Comparative mechanical screening
SSF is a pre-selection and process-control framework. Final performance must always be validated under real application conditions.
