Resin Selection by Application Severity
This quick engineering map helps position your application according to real performance demand and select the appropriate material level without over-specifying or under-specifying the resin system.
Use this page as a fast routing tool. For the complete methodology, use the full Material Selection & Ordering Guide.
Move from standard to thermoplastic-like as application severity increases. Each level represents a different reliability threshold based on load, durability, service life and failure tolerance.
Low application severity
Appropriate for visual models, concept validation and simple parts where mechanical demand is limited.
- Low load
- Short service life
- Cost-sensitive use
- Basic handling requirements
Only required if improved toughness, handling resistance or early functional testing is needed.
- Enhanced prototypes
- Better handling resistance
- Moderate functional validation
Usually not required for low-demand applications unless the project is expected to scale into higher performance requirements.
- Future scalability
- Early qualification for demanding workflows
Medium application severity
Standard materials may start to fail when exposed to repeated handling, assembly stress, moderate load or longer service conditions.
- Assembly stress
- Moderate load
- Limited durability
- Repeated handling
Balanced option for functional parts requiring improved toughness, stability and a broader performance window.
- Higher toughness
- Improved thermal resistance
- More stable behaviour
- Functional prototyping
Recommended when the cost of failure is higher or when the user wants to minimize the risk of brittle behaviour.
- Extended durability
- Improved reliability margin
- More demanding functional use
High application severity
High risk of brittle failure, instability or insufficient functional lifetime under demanding service conditions.
Useful as an intermediate route, but may still be insufficient for critical or long-duration functional applications.
Designed for real engineering performance where toughness, durability and functional reliability are central selection criteria.
- High toughness
- Durability
- Functional reliability
- Lower tolerance for failure
Quick rule
Visual or low-load use → Standard materials
Functional use → Next-generation materials
Critical or demanding use → Thermoplastic-like materials
Material families
Use these material family routes after identifying the severity level of your application.
Use the full selection guide when you need to connect application requirements, printer technology, material platform, calibration, validation and ordering.
Final insight
The correct resin is not defined by price or speed alone, but by the severity of the real application.
Performance requirements define the material level, not the other way around.
