Scientific Director

Profile

Dr. Juan Segurola is the founder and Scientific Director of 3Dresyns by Resyner Technologies S.L. He holds a BS in Chemistry, specialized in Polymer Science, from the University of the Basque Country (Spain), and a PhD in Photochemistry of Polymers from Manchester Metropolitan University (MMU, UK).

Scientific career fields

Materials science, polymer chemistry and photochemistry. Synthesis, analysis, design and production of synthetic and bio-based resin systems in water-based, solvent-based and 100% solids photopolymer formats for 2D and 3D printing and additive manufacturing.

Academic institutions

Doctoral supervisor

Professor Norman Allen, Manchester Metropolitan University (MMU).

Academic background

Dr. Segurola graduated in Chemistry in 1994 from the University of the Basque Country, with a five-year degree specialized in Polymer Science. He completed his final undergraduate year at Manchester Metropolitan University on an Erasmus scholarship, where he conducted research on the synthesis of novel anthraquinone and benzophenone photoinitiator derivatives under the supervision of Professor Norman Allen.

He obtained his PhD in Photochemistry of Polymers from Manchester Metropolitan University in 1999. The doctoral research was undertaken within an industrial-academic framework between Swale Process, Manchester, UK, and the Department of Chemistry and Materials at Manchester Metropolitan University. He was already employed by Swale Process as an R&D scientist before commencing the PhD and carried out the doctoral research while working as a salaried industrial researcher.

DOI-indexed publication record

226 public records with permanent DOIs, all publicly accessible: 192 3Dresyns technical papers and reports, 3 public datasets and controlled documentation corpora, and 31 science communication works. The three groups are listed separately below and are not interchangeable: they differ in field, audience and evidence standard.

3Dresyns technical and engineering publications

The 3Dresyns paper-level publication programme comprises 192 papers and reports: 137 Engineering Reviews across the ER-01–ER-138 identifier range, 50 Technical White Papers, 3 Engineering-Led Photopolymer Additive Manufacturing perspective papers, and 2 Research/Review Papers (RP-01 and RP-02). Author of record: Juan Segurola, 3Dresyns by Resyner Technologies S.L.

The corpus is published as the tenth-anniversary programme of Resyner Technologies S.L., constituted on 26 September 2016: the company’s engineering review and technical white paper output consolidated into a single citable, versioned and permanently archived public record. The complete record is maintained in the 3Dresyns Engineering & Technical Publications community on Zenodo.

ER-35 was consolidated into ER-36 during the Route A scientific remediation programme and was therefore not issued as a separate publication. The identifier is retained so that the numbering remains transparent and auditable, which is why the ER-01–ER-138 range contains 137 published records rather than 138.

Every DOI on this page is a concept DOI. A concept DOI always resolves to the current version of its record, so these citations stay correct as papers are revised. Cite a version DOI only when you need to reference one specific revision.

On 21 August 2026, the coordinated publication programme completed and verified a 96-paper controlled release: 76 existing Zenodo records were updated as new versions and 20 new Route A records were created. The publication workflow preserved existing concept DOIs where applicable and verified the released records after publication.

Engineering perspectives and qualification frameworks

The first three papers form the 2026 Engineering-Led Photopolymer Additive Manufacturing Biocompatibility perspective trilogy: framework, industrial implementation and wavelength-matched audit methodology. RP-01 develops the electrically functional photopolymer framework; RP-02 defines the common evidence-to-decision qualification architecture used by the Route A Engineering Qualification Notes.

  1. Paper I · Biocompatibility in Dental Photopolymer Additive Manufacturing: A Material–Process–Workflow Perspective
    DOI: 10.5281/zenodo.21969972
  2. Paper II · Industrial Implementation of a Material–Process–Workflow Framework in Dental and Hearing-Device Photopolymer Additive Manufacturing
    DOI: 10.5281/zenodo.21973421
  3. Paper III · Wavelength-Matched Process Control as a Prerequisite for the Post-TPO Photopolymer Transition
    DOI: 10.5281/zenodo.21973553
  4. RP-01 · Electrically Functional Photopolymer Resins for Vat Photopolymerization

The complete series pages carry the abstracts and publication status for every record: 3Dresyns Engineering Reviews and the Technical White Paper Series.

Public technical datasets and controlled documentation corpora

In addition to the paper-level publication programme, 3Dresyns maintains open, citable technical datasets and controlled documentation corpora to support provenance, reproducibility and long-term access to public technical information.

  • 3Dresyns Additive Manufacturing Materials Property Dataset — Version 1.0. A provenance-preserving dataset derived from 480 public Technical Data Sheets, representing 480 products and 3,957 structured material-property records across mechanical, physical, thermal, electrical, optical and process-related domains.
    DOI: 10.5281/zenodo.22015609
  • 3Dresyns Additive Manufacturing Instructions for Use (IFU) Corpus — Version 1.0. A controlled collection of 38 public Instructions for Use documents covering general and printer-specific additive-manufacturing workflows, calibration, curing, cleaning, post-processing and specialised manufacturing routes.
    DOI: 10.5281/zenodo.22016929
  • 3Dresyns Technical Web Publications and Engineering Documentation Corpus — Version 1.0. A controlled archival snapshot of 38 technical web publications, with archival PDFs, corresponding HTML source snapshots, structured provenance and checksum information.
    DOI: 10.5281/zenodo.22018151

These engineering perspectives, reviews, white papers, datasets and technical corpora are maintained separately from the conventional peer-reviewed journal publication record. Zenodo provides persistent DOI-based access, version control and archival traceability; repository publication does not itself imply external journal peer review unless explicitly stated for the individual work.

The Universe and Its Observers / El universo y sus observadores

A long-form science communication programme for curious readers with no scientific training, written in parallel English and Spanish editions of the same conceptual work. Its flagship series is From Quarks to Consciousness — Science, Nature and the Universe Explained for Everyone — which follows two intertwined narratives: the cosmic history that leads from a simple universe to observers within it, and the human progression from perception and myth to mathematics and the scientific method.

The programme applies the same evidence discipline as the engineering corpus. Every article carries an explicit epistemic classification, so that established knowledge, current interpretation, active hypotheses, open problems and philosophical interpretation are never presented as the same kind of statement. Article numbering is permanent and never reused, and the English and Spanish texts are editions of one work rather than translations of a primary language.

31 records published with permanent concept DOIs: 27 numbered articles of the first season, together with 4 collected volumes and the canonical index. Maintained in the The Universe and Its Observers community on Zenodo. This programme is a separate authorial body of work and is not part of the 3Dresyns technical publication record above.
