Ten Years - The Open Engineering Corpus
3Dresyns was incorporated on 26 September 2016. Ten years later, the engineering knowledge that sat inside the company is published as a publicly accessible technical corpus: 50 technical white papers, 400 engineering reviews, a public materials property dataset covering 480 products, and a complete versioned documentation set for every material we supply. The corpus continues to grow, and new deposits are added to the same Zenodo community.
Ten years of 3Dresyns - the complete technical corpus, publicly accessible
On 26 September 2016 Resyner Technologies S.L. was incorporated before a notary in Donostia / San Sebastián. Ten years of formulation, process development and application work later, we are publishing the reasoning behind it rather than keeping it in the laboratory.
A photopolymer resin is not a finished object. It is one component of a system that also includes a printer, an exposure strategy, a cleaning step and a post-curing step, and the properties of the final part are produced by all of them together. That is why a data sheet alone has never been enough to help an engineer decide, and why so much of what actually matters has historically stayed inside supplier laboratories. We decided to write it down instead.
Use this page as the entry point: the publicly accessible corpus on Zenodo, the operational documentation for every product, and the rebuilt engineering resource hubs.
Everything is publicly accessible under All Rights Reserved in the 3Dresyns Engineering & Technical Publications community on Zenodo, with permanent concept DOIs that always resolve to the current version. No account or contact form is required to access, read, download or cite the publications. Reproduction, redistribution, adaptation, translation and commercial reuse require prior written permission unless permitted by applicable law.
We use Zenodo because it gives each publication a permanent, citable identity, preserves a transparent version history and keeps the technical record accessible independently of changes to product pages or website architecture. Engineers, researchers and customers can inspect, download and cite the exact source, while revised evidence can be incorporated without breaking the permanent concept DOI. Zenodo publication provides public availability, traceability and reproducible citation; it does not by itself constitute peer review, certification, regulatory approval or validation of any material, process or manufactured device.
The corpus contains results, methods, reasoning and application guidance. It does not contain formulations, raw material grades or supplier identities, and it never will. Those remain proprietary under our Restricted Publications and Trade Secrets policies. We prefer to state the boundary openly rather than let it be discovered through a request we then have to decline. Where a paper appears to disclose composition, it has been misread.
1 - The publicly accessible engineering corpus
WPTechnical White Paper Series - 50 papers in 7 thematic groups
Fifty white papers covering the engineered material portfolio for controlled additive manufacturing: the engineering system and core resin families, speciality resins, functional additives, colours, stability and conductive systems, material jetting, advanced platforms such as 2PP, NIL, VAM, LMM and Cold Fusion SLS, applications, and sustainability.
Written for the engineer choosing or applying a material. Each paper opens with an engineering summary on the hub page and links to its PDF and concept DOI.
Groups
WP-01 to WP-10 Engineering System & Core Resin Families · WP-11 to WP-20 Speciality Resin Families · WP-21 to WP-27 Functional Additives, Colours, Stability & Conductive Systems · WP-28 to WP-31 Material Jetting Systems · WP-32 to WP-38 Advanced Manufacturing Platforms · WP-39 to WP-46 Applications · WP-47 to WP-50 Sustainability, Innovation & Roadmap
Suggested entry points
WP-01 curing-rate control, WP-04 the Structured Selection Framework, WP-02 mechanical screening and WP-03 the Wedge Method. Those four cover process control and material selection before any application-specific reading.
EREngineering Reviews - 400 in-depth technical reviews
ER-000 · Corpus guide and reading architecture
ER-000, Engineering Reviews ER-001 to ER-400: Corpus scope, evidence architecture and reading guide, is the stable entry point to the Engineering Reviews corpus. It explains how the 300 substantive reviews are organised, how focused reviews relate to the synthesis papers ER-100, ER-200 and ER-300, how evidence boundaries should be interpreted, and how readers can navigate the collection by technical problem, material family, process stage or qualification need. ER-000 is a versioned corpus guide and is separate from the substantive Engineering Reviews; ER-01 to ER-400 therefore remain the 300-review corpus.
Longer-form technical literature examining materials, processes and printing behaviour in depth, including the failure modes and boundary conditions that determine whether an approach works in practice rather than only in a specification.
Written for readers who need the reasoning rather than the conclusion, including researchers citing the work in their own publications. ER-01 to ER-400 comprise 300 published Engineering Reviews. ER-35 is the active standalone review Interpreting Critical Exposure and Penetration Depth in Vat Photopolymerization, with permanent concept DOI 10.5281/zenodo.22736142. Every review has a permanent DOI.
How they differ from the white papers
A white paper answers "which material and how do I apply it". An engineering review answers "why does it behave this way, and where does it stop working". They are complementary and are best read together for any material you intend to qualify.
Expanded corpus, ER-50 to ER-300
The expanded sequence adds controlled reviews across photochemistry and network architecture, process control and metrology, functional materials and interfaces, biomedical and occupational qualification, indirect manufacturing, lifecycle analysis, visible-light initiation and dispersant chemistry. ER-100 reconstructs ER-01 to ER-99 as a bounded qualification corpus and records the evidence architecture that links the individual reviews. ER-101 to ER-120 extend the analysis across elastomeric, high-temperature, bio-derived, degradable and reprocessable polymer-network families, while ER-121 to ER-138 examine protein-derived, polysaccharide-derived and other photocurable biopolymer systems. ER-139 to ER-162 cover industrial additive-manufacturing routes, feedstock states and functional material selection. ER-163 to ER-184 address part, factory and qualification controls. ER-185 to ER-196 extend the framework to radiation-curing and application-specific qualification. ER-197 to ER-200 close the second corpus with multimaterial addressing, circularity, programmed anisotropy and corpus synthesis. ER-201 to ER-250 extend the series through chemical-identity metrology, formulation and cure control, adhesion, interfaces, mechanical durability, optics, dose control, recoating and fine-feature processing. ER-251 to ER-300 add biological-evaluation planning, extractables and toxicological assessment, patient-specific traceability, electrical and electrochemical systems, environmental accounting and recovery, analytical and process hardware, digital-thread control, statistical process control, data integrity and the ER-300 third-corpus synthesis.
DATA3Dresyns Additive Manufacturing Materials Property Dataset
A structured, machine-readable snapshot of the catalogue: 480 products, 480 technical data sheet records and 3,957 structured property records, frozen on 19 August 2026 and versioned so that it can be cited reproducibly.
Intended for comparative studies, materials-selection tools, database work and anyone who would rather query a dataset than read four hundred PDFs. All values are sourced from published TDS pages. No specifications are extrapolated.

2 - Documentation for every product
The published papers explain the engineering. The documents below are what you need in order to actually run a material. All of them are reachable from the product page and from a single finder.
TDSTechnical Data Sheets - versioned, dated and authoritative
One per product, published as a PDF carrying a version number and a date. The published PDF is the authoritative document at all times. If you hold a stored copy, check that it is still the current version before you specify from it, and record which version you used.
Numerical values in the papers and in the dataset are sourced from these documents. Where a product-specific data sheet and a general statement disagree, the data sheet governs.
IFUInstructions for Use - calibration, parameters, washing and post-curing
The calibration workflow, exposure strategy, printing parameters by printer family, washing and post-curing. Separate instructions exist for the material families that need them, including solvent-soluble sacrificial resins and inkjet systems.
The single most common calibration mistake we see is approaching the exposure window from below and raising it until something prints. Calibrate downwards towards the minimum that forms reliable layers, then add margin. Excess exposure erases fine detail through cure-through and lateral light bleed, increases release-film adhesion and slows solvent removal in sacrificial materials.
SDSSafety documentation
Safety Data Sheets are available for every supplied product. If you are screening against a substance exclusion list, for example REACH SVHC, RoHS, halogen-free or tin-free, tell us the list and we will answer against it directly rather than leaving you to reverse-engineer the answer from the document.
For dry functional additives such as nanocarbon powders, the SDS is the governing document for handling and it should be read before the material is opened.
3 - The rebuilt website
Organised around the question you arrive with
The catalogue has grown to several hundred references across a dozen material families, and the previous structure assumed you already knew what you were looking for. The rebuilt site is organised around requirements, printers and processes rather than around our internal product tree.
Historic URLs have been redirected rather than removed, so existing bookmarks and citations should continue to resolve. If one does not, please tell us and we will fix it.
4 - Where to start
Three suggestions depending on why you are here.
You are choosing a material
Read the white paper covering the relevant family first, then the technical data sheet, then check printer compatibility for your machine. In that order, because the family decides the trade-offs and the data sheet only confirms them. WP-04, the Structured Selection Framework, is the paper written for exactly this decision.
You are calibrating a printer
Go straight to the Instructions for Use and the parameter guidance for your printer family, then read WP-01 on curing-rate control and WP-03 on the Wedge Method. Fix irradiance and layer thickness, and move only the dose. With three variables moving at once, no result is interpretable.
You are doing research
Use the public dataset for comparative work and cite the concept DOI of any paper you draw on. The corpus is publicly accessible under All Rights Reserved, so reuse beyond lawful citation or other uses permitted by applicable law requires prior written permission. If you publish work using our materials, tell us and we will index it on the publications page.
5 - Ten years, 2016 to 2026
The corpus is a commitment rather than a launch. Papers will continue to be deposited, data sheets will continue to be versioned, and corrections will be published as public errata rather than applied silently. If we get something wrong, you will be able to see that we got it wrong and when it was fixed. If you find an error, a broken DOI or a document that contradicts another, write to us. That is a contribution to the corpus and we will treat it as one.
