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 an open technical corpus: 50 technical white papers, 49 engineering reviews, an open 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, now open access
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 open corpus on Zenodo, the operational documentation for every product, and the rebuilt engineering resource hubs.
Everything is open access under a CC BY 4.0 licence in the 3Dresyns Engineering & Technical Publications community on Zenodo, with permanent concept DOIs that always resolve to the current version. No account, no contact form and no permission request is required. You may reuse it with attribution.
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 open 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 — 49 in-depth technical reviews
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-49, all with permanent DOIs.
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.
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 open dataset for comparative work and cite the concept DOI of any paper you draw on. Everything is CC BY 4.0, so you may reuse it with attribution and without asking us first. 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.
