Photocurable Putties and UV Adhesives — the 3Dresyns Non-Printed Functional Family

This white paper covers photocurable putties and UV adhesives as the non-printed functional family of 3Dresyns materials. Not all photopolymer technologies are printed. UV-curable putties, fillers, sealants and adhesives provide bonding, repair, filling, sealing, fixation and man...

Fine Tuners

This white paper documents the Fine Tuner portfolio at system level, including FT family photoaccelerants and LB family light-blocking routes for process and resolution adjustment. Fine Tuners allow users to adjust photoreactivity, cure depth, speed, resolution, optical behaviour...

Wavelength-Matched Process Control as a Prerequisite for the Post-TPO Photopolymer Transition

TPO was added to the REACH Candidate List on 14 June 2023 because of its reproductive-toxicity properties. Commission Delegated Regulation (EU) 2024/197, adopted on 19 October 2023 and published in 2024, introduced the corresponding harmonised classification under the CLP framewo...

ESD-dissipative VPP photopolymers — the 3Dresyns electronics portfolio

This white paper covers ESD-dissipative VPP photopolymers for electronics manufacturing, fixtures, handling tools and electrostatic-control workflows. ESD performance must be evaluated as a surface-resistivity range under defined cure, post-cure and environmental conditions. Mech...

Processing Auxiliaries

This white paper covers processing auxiliaries used to support cleaning, smoothing, sacrificial printing, purification and workflow adaptation. Auxiliaries are part of the manufacturing system. Their function is to adapt the process environment around the resin: cleaning, smoothi...

Radiopaque and Radio-Transparent VPP Photopolymers

This white paper covers radiopaque and radio-transparent VPP photopolymers for diagnostic, imaging, shielding and device-development workflows where interaction with X-rays or other radiation-relevant modalities is part of the material function. Radiopacity and radio-transparency...

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...

The 3Dresyns Fine Tuner system

The Fine Tuner white paper describes modular in-resin process adjustment for photoreactivity, resolution, light penetration, surface definition, cure depth and platform adaptation. Fine Tuners allow controlled adjustment of a base resin without redesigning the full formulation. T...

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...

Industrial Implementation of a Material–Process–Workflow Framework in Dental and Hearing-Device Photopolymer Additive Manufacturing

The Material–Process–Workflow framework developed in the first paper of this trilogy proposes that device-level biological performance in photopolymer additive manufacturing is determined by the coupled interaction of material chemistry, cure kinetics and post-processing workflow...

Aerospace and Space Manufacturing

This white paper covers aerospace and space manufacturing applications using high-performance 3Dresyns materials, including structural, high-HDT, ESD and indirect-manufacturing routes. Aerospace material selection requires high mechanical performance, thermal stability, dimension...

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 —...
