Which 3D resin should I use?
Most users do not fail because of the resin itself, but because they choose the wrong material for the real application, process window or performance target.
This page is designed as a fast decision route to help users identify the most relevant 3Dresyns® material family before moving into deeper product comparison, documentation or calibration.
If your application combines several constraints such as mechanics, thermal resistance, safety, resolution or process compatibility, use the structured tools below.
Start from your application
Low-cost models and visual prototyping
Choose this route if the main objective is affordable model making, visual prototyping or non-demanding general use.
General-purpose functional parts
Choose this route if you need standard photopolymer materials for broad functional applications, general engineering use and routine printing workflows.
Next-generation 3D resins organized across rigid, tough, foldable, flexible and elastic functional photopolymers
Choose this route if the application requires stronger mechanical positioning, advanced functionality, better thermal performance or more demanding engineering targets.
High-performance thermoplastic-like engineering and functional materials
Choose this route if the target is to print thermoplastic-like photopolymer resins similar in performnce to PEEK, ABS, POM, HDPE, HIPS, LDPE, Nylon, PC, TPU, PET, PMMA and PP.
Biocompatible workflows
Choose this route if the material must align with biocompatibility-oriented applications or if safer formulation logic is required in regulated or sensitive environments.
Dental and orthodontic applications
Choose this route for dental models, orthodontic workflows and related precision applications requiring dedicated material families.
Castable applications
Choose this route for jewelry casting, investment casting and workflows where clean burnout or sacrificial behavior is a key material requirement.
Sacrificial, support, mold-making and indirect manufacturing routes
Choose this route if the printed material is not the final functional part, but part of a support, mold, pattern or sacrificial workflow.
If you are not sure which family fits
Use this logic:
- Price-sensitive prototypes: start with low-cost basic resins
- General functional printing: start with standard resins
- Higher mechanical or functional demand: move to next-generation functional resins
- Soft or flexible behavior: use flexible and elastic families
- Biocompatibility-oriented need: use biocompatible families
- Dental workflow: use dental-specific resins
- Casting or burnout: use castable resins
- Molds, supports or sacrificial logic: use sacrificial and mold-making resins
Important technical note
Final performance depends on the interaction between resin formulation, printer technology, light power, layer thickness, post-processing and calibration strategy.
For controlled and reproducible printing, 3Dresyns® recommends calibration through the CRT framework rather than relying on fixed assumptions or generic settings.
Need a more precise recommendation?
If your application combines several constraints such as resolution, toughness, HDT, safety profile, chemical resistance or indirect manufacturing requirements, use the guided routes instead of selecting only by product family.
