Biocompatible photopolymer systems for advanced additive manufacturing workflows requiring controlled biological interaction, dimensional precision and mechanical reliability.
3Dresyns® biocompatible materials are engineered as workflow-dependent material systems whose final performance depends on validated processing, cleaning and post-curing conditions.
Navigate by: structural behaviour, hardness range and intended workflow logic.
Select a material route to identify the most relevant biocompatible family before validating the final workflow.
Biocompatibility framework
Biocompatibility-related testing may be performed under controlled laboratory conditions, including ISO 10993-based evaluations where applicable, depending on the formulation and version.
Reported results represent typical responses obtained under defined reference configurations and should not be interpreted as intrinsic or unconditional properties of the liquid resin alone.

How to choose the right biocompatible material
Select the most suitable material according to structural behaviour, hardness range and formulation profile.
Decision guide
-
Ultra rigid / high thermal resistance → Biorigid R190D90, Biorigid R140D90
-
Tough rigid materials → Biotough D90 / D80 / D70
-
Semi-rigid to flexible → Bioflex D60, A90, A80, A70
-
Soft flexible → Bioflex A60, A50, A20, A10
-
Elastic behaviour → BioElastic O50
Formulation preference
-
Prefer monomer-free workflow → choose MF grades where available
-
Standard monomer-based workflow acceptable → choose MB grades where available
Engineering rule
Decision tree summary
Use this simplified engineering logic before detailed workflow validation.
Decision steps
-
Need maximum rigidity / thermal resistance → Biorigid
-
Need tough rigid response → Biotough
-
Need flexible or soft behaviour → Bioflex
-
Need more elastic recovery → BioElastic
Then validate final suitability under the intended cleaning, post-curing and IFU-qualified workflow.

Workflow-dependent performance
Mechanical behaviour, surface characteristics, dimensional accuracy and biological interaction outcomes depend on multiple interacting variables, including formulation version, exposure conditions, printer calibration, washing procedure and post-curing protocol.
Successful implementation therefore requires alignment between material selection, equipment capability, process validation and strict adherence to qualified Instructions for Use.

3Dresyns biocompatible materials are supplied as professional manufacturing materials for additive manufacturing workflows. They are not marketed as finished medical devices unless explicitly stated for a specific product and jurisdiction.
The regulatory classification, conformity assessment, validation and compliance of any final medical device manufactured using these materials remain the sole responsibility of the legal manufacturer of that device in accordance with applicable regulations, including Regulation (EU) 2017/745.
3Dresyns biocompatible photopolymers should be understood as workflow-dependent material systems. Final performance and biological response are outcomes obtained under qualified processing conditions, not intrinsic constants independent of equipment, exposure strategy, cleaning and post-curing variables.
Biocompatible 3D Printing: System-Level Performance
Biocompatibility in vat photopolymerization is not defined by the liquid resin alone. Final safety and performance depend on formulation design, residual species control, printing conditions, post-processing and application-specific validation.
3Dresyns® biocompatible systems are engineered to support controlled manufacturing workflows where extractables, polymer conversion and surface chemistry are managed at system level.
Key technical principle
Photopolymer conversion is never complete. Residual species may remain within printed parts and can influence extractables and biological response depending on processing conditions.
Monomer Free (MF) formulation strategy
3Dresyns Monomer Free (MF) resin systems are designed to reduce the presence of reactive residual species at the formulation level, contributing to improved control of extractables when processed under validated workflows.
Why workflow control matters
- printing parameters influence polymer conversion and internal structure
- geometry affects light penetration and curing uniformity
- post-processing defines residual species removal
- application conditions determine extractable behavior
Final performance must always be evaluated as a material–printer–process–post-processing system, not as an isolated resin property.
