The MF Biocompatible VPP Framework — Monomer-Free Formulation as a Regulatory Engineering Strategy

This white paper presents the MF Biocompatible VPP Framework, positioning monomer-free formulation as an engineering strategy for reducing regulatory, toxicological and extractables-related risk in professional manufacturing workflows. Biocompatibility is not only a material labe...

Bio-Scaffolds Portfolio for SLA, DLP and LCD

This white paper covers the Bio-Scaffolds portfolio for tissue-engineering and research workflows using SLA, DLP and LCD photopolymerisation. Bio-scaffold materials must be assessed through scaffold architecture, pore geometry, print fidelity, mechanical compliance, cleaning, ste...

Innovation Timeline — 3Dresyns® Photopolymer and Powder Platform 2017–2025

This white paper documents the 3Dresyns® photopolymer and powder platform innovation timeline from 2017 to 2025. The timeline frames platform development as a sequence of material-system innovations, including monomer-free biocompatible systems, advanced photopolymer families, po...

Water-Soluble Sacrificial Portfolio (IM-WS) for SLA, DLP and LCD

Indirect additive manufacturing addresses a structural limitation of direct 3D printing: enclosed channels, undercuts and intertwined cavities cannot be deposited directly. The 3Dresyns® IM-WS family of water-removable sacrificial photopolymers prints a temporary tool by SLA, DLP...

UHV Bio Portfolio for Viscous Lithography Manufacturing and Hot Lithography

This white paper covers the UHV Bio portfolio for Viscous Lithography Manufacturing and Hot Lithography, including high-viscosity professional manufacturing materials with high thermal resistance. High-viscosity and heated-photopolymer workflows expand the material design space b...

Inkjet supports and auxiliaries — removal-route engineering for material jetting workflows

This white paper covers inkjet supports and auxiliaries for material jetting, including water-soluble, meltable and breakaway support-removal routes. Support material performance is defined by print compatibility, adhesion, removability, residue, thermal behaviour, cleaning route...

Silicone-like and PDMS-like VPP Photopolymers

This white paper covers silicone-like and PDMS-like VPP photopolymers for flexible, compliant and microfabrication-oriented workflows where elastic response, surface behaviour and soft-material handling are central. Silicone-like and PDMS-like VPP materials are selected when comp...

Optical Selection System (OSS)

The OSS white paper presents the Optical Selection System for refractive-index-tuned optical VPP grades, including transparent, translucent and optical-function photopolymers. Optical material selection requires matching refractive index, transparency, colour, haze, curing behavi...

Biodegradable VPP Photopolymers — BioDeg Corn Series

This white paper covers the BioDeg Corn series of biodegradable VPP photopolymers, including biodegradation framing, end-of-life considerations and validation methodology. Biodegradability is not equivalent to general environmental disappearance. It must be evaluated under define...

Engineering & Functional VPP Portfolio for SLA, DLP and LCD

This white paper maps the engineering and functional VPP resin portfolio for SLA, DLP and LCD platforms, from rigid and tough grades to elastic, high-temperature, optical, conductive and application-specific material systems. The portfolio is organised by real structural and func...

The 3Dresyns Structured Selection Framework (SSF)

The SSF white paper organises material selection as a structured workflow based on application, mechanical profile, process platform, post-processing route, regulatory context and final part requirements. The correct resin is not selected by technology alone. The SSF links use ca...

3Dresyn PEEK-like — Polyetheretherketone-like VPP Photopolymer with Ultra-High Flexural Strength 120–140 MPa

This white paper covers 3Dresyn PEEK-like, a high-performance VPP photopolymer designed to approximate a PEEK-like engineering positioning with ultra-high flexural strength in the 120–140 MPa range. The material is positioned for applications requiring high stiffness, high flexur...

Cold Fusion SLS Powder Binders for CMF, CCF, CPF and CEPF - the 3Dresyns Powder-Binder Family

This white paper covers the 3Dresyns Cold Fusion SLS powder-binder family for CMF, CCF, CPF and CEPF routes: a binder-assisted, mould-free indirect sintering route on standard SLS hardware, where the laser fuses a co-binder — or, with the self-sufficient CF3, the binder itself —...

Electrically Functional Photopolymer Resins for Vat Photopolymerization

Problem. Additive manufacturing of electrically functional parts has progressed from filament-based conductive thermoplastics into vat photopolymerisation (VPP) systems capable of micron-scale resolution, enabling printed electronics, electrostatic-control fixtures, bioelectronic...

HELM - Topology-Adaptive Geometric Routing with Non-Equilibrium Path Estimation and Orthogonal Channel Encoding

HELM (Hyperbolic Embedding with Langevin Manifolds) is a layered routing architecture for networks where topology and traffic both change faster than conventional protocols comfortably assume. It combines three separable layers: a geometric forwarding layer that selects between h...

Biocompatibility in Dental Photopolymer Additive Manufacturing: A Material–Process–Workflow Perspective

Direct-printed orthodontic aligners, denture bases and dental prostheses are scaling in clinical use, but the published dental literature has predominantly approached photopolymer biocompatibility from a chemistry-centred perspective. The 2023 REACH SVHC listing of TPO and the su...

Help-seeking and accessing treatment for eating disorders: a systematic review of qualitative studies with a focus on ethnic differences

Abstract Background Eating disorders (ED) are serious mental health conditions characterised by disordered eating behaviour and associated emotional distress. EDs are associated with high rates of mortality and morbidity, yet rates of help-seeking remain low. There is a misconcep...

The Pelletier Concentric Brane Hypothesis

This document proposes a speculative cosmology hypothesis combining higher-dimensional braneworld theory with a curvature-dependent mechanism for energy exchange between our observable universe (a "brane") and a higher-dimensional bulk. The central proposal is that extreme locali...
