Instructions for Use & Printing Parameters
3Dresyns® Instructions for Use (IFU) & Printing Parameters define qualified reference workflows and recommended parameter windows for using 3Dresyns® multivariable material systems across different printing technologies, advanced manufacturing routes, applications and material configurations.
3Dresyns® materials are process-dependent systems. Final performance depends on the full material–printer–process–post-processing chain, including formulation version, printer or process technology, exposure or energy-delivery strategy, processing parameters, curing or consolidation behavior, downstream manufacturing steps and post-processing workflow.
IFU defines the validated operational workflow, while engineering-control documents, calibration logic and process-validation methods provide the technical control tools required to implement it reproducibly where such methodologies are available.
Use IFU together with the relevant engineering-control, calibration and validation documents to implement 3Dresyns® materials as controlled engineering systems rather than fixed “one-setting” products.
Defines qualified workflows for printing, processing, washing, debinding, curing, consolidation or downstream use depending on the selected technology.
Defines the calibration logic, process-control tools and optimization framework available for the selected technology.
Verifies dimensional accuracy, process stability, handling behavior or downstream manufacturability under controlled test conditions.
Validates final material behavior under controlled conditions when mechanical qualification is relevant.
Start with IFU, add the relevant engineering-control and calibration framework where available, verify process stability and dimensional fidelity, and use SMSP when final mechanical validation is required.
How IFU, engineering control and process validation work together
3Dresyns® processing methodology is not based on isolated settings but on a structured implementation logic:
- IFU: defines the qualified operational workflow for the selected material and technology
- Engineering control: defines calibration logic, process windows and optimization methods where available
- Process validation: verifies dimensional stability, process reproducibility, handling behavior and workflow robustness
Together, these layers connect operating procedure, process control and technical validation into a reproducible engineering workflow.
Engineering implementation logic
- Step 1 — Follow the core technology IFU: establish the qualified reference workflow for the selected material and manufacturing platform
- Step 2 — Use the relevant engineering-control tools: understand and adjust curing, jetting, writing, thermal, powder or volumetric process behavior where such methodologies are available
- Step 3 — Apply process validation: verify dimensional fidelity, process stability and downstream manufacturability
- Step 4 — Validate final performance: confirm the full workflow under the intended application conditions

Structure of Instructions for Use (IFU)
IFU documentation is organized in four practical layers: a general IFU framework, engineering control, calibration and process validation, printing technologies and cross-platform process tools, and specialized manufacturing and application workflows.
Level 1 — General IFU framework
This document defines the general implementation philosophy used across 3Dresyns® materials and workflows.
Level 2 — Engineering control, calibration and process validation
These documents define the engineering control tools, calibration logic and process-validation methods used to improve reproducibility, dimensional accuracy, process stability and technical interpretation where such methodologies are available.

Level 3 — Printing technologies and cross-platform process tools
These IFUs define the main technology-specific processing rules and supporting process tools used across 3Dresyns® materials.

Level 4 — Specialized manufacturing and application workflows
These IFUs extend the core technology framework with downstream manufacturing logic, specialized processing routes and end-use application guidance.
Lithography-based routes for debinding and sintering
- Direct printing of sintering ceramics, metals and exotic materials
- Binders for Lithography-based Metal Manufacturing (LMM)
These two documents define the main implementation logic for 3Dresyns® routes designed for direct printing of sintering ceramics, metals and exotic materials, where the printed object is an intermediate green body that must subsequently undergo debinding and final thermal conversion or sintering.
Defines the full workflow logic, formulation route, powder-selection and dispersion requirements, fine tuning, green-part handling, debinding logic, sintering logic, repeatability and failure interpretation.
Provides a rapid starting route for first implementation, fast exposure selection, platform adhesion logic, early formulation tuning and structured first validation.
Recommended sequence: start with the Fast IFU for rapid first implementation, then move to the Full IFU for full formulation logic, debinding strategy, sintering logic and repeatable process qualification.

How to use this IFU structure
- Start with the core technology IFU that matches the printing or manufacturing platform.
- Add the relevant process-specific or application-specific IFU when the intended use requires extra workflow logic, downstream process guidance or end-use validation.
- Use the relevant engineering-control tools whenever calibration, curing control, dimensional verification or process optimization are available for the selected technology.
- Validate the final workflow under real conditions for the intended application, substrate, geometry, post-processing route or downstream manufacturing sequence.
IFU system architecture
Biocompatibility, safety and performance in photopolymer 3D printing cannot be defined by a single document. They are the result of a structured, multi-level documentation system.
Governing principle
3Dresyns® materials are multivariable polymer and process systems. IFU defines validated workflows, engineering-control documents define calibration and process-validation logic where available, and technology-specific IFUs define implementation rules for each manufacturing platform. Final performance depends on formulation version, printer or process technology, processing parameters, post-processing conditions and the intended application workflow, and must be validated by the user for the intended use.
