Two-photon polymerization — sub-100 nm photopolymer 3D printing

This white paper covers two-photon polymerization for sub-100 nm photopolymer 3D printing using specialised resins and Fine Tuner systems for VIS-NIR and 1035 nm femtosecond laser platforms. 2PP requires a different formulation logic from standard VPP: two-photon absorption effic...

4D Shape-Memory VPP Photopolymers

This white paper describes 4D shape-memory VPP photopolymers, where printed parts can be programmed to change shape or recover geometry under controlled stimulus after printing. 4D shape-memory behaviour requires coupling between polymer network architecture, transition temperatu...

Bio-based VPP photopolymers

This white paper covers bio-based VPP photopolymers with high bio-carbon content, framing renewable-carbon formulation as one pathway toward lower-impact additive manufacturing materials. Bio-based content must be treated as a measurable material attribute rather than a vague sus...

Forward Directions 2025–2030 — Five 3Dresyns® Innovation Tracks Already in Public Development

This white paper covers forward directions for 2025–2030, organised around five innovation tracks already in public development. The roadmap frames future material systems around circular and depolymerisable chemistries, self-healing and reprocessable matrices, conductive electro...

LMM Reactive Solid Binders and Castable Solid Photopolymers — RSB1 WD, RSB1 SD, LMM Perfect Cast PC1, PC2 and PC3

This white paper covers lithography-based metal manufacturing materials, including reactive solid binders and castable solid photopolymers for LMM workflows. LMM requires binder systems compatible with highly loaded metal or ceramic feedstocks, green-part handling, debinding, sin...

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...

Biological response in photopolymer additive manufacturing: a review of formulation chemistry, workflow variables and qualification constraints in dental and biomedical applications

Photopolymer vat photopolymerisation has expanded from prototyping into manufacturing and research workflows for dental and biomedical devices, including direct-printed clear orthodontic aligners, denture bases, surgical guides and research platforms. The regulatory environment h...

Color Stability and Light Fastness

This white paper covers colour stability and light fastness across the colour portfolio, addressing photochemical durability, ageing, exposure and visual performance retention. Colour stability depends on pigment chemistry, UV exposure, post-cure, thermal history, matrix formulat...

Conductive and Electronics 3D Resins

This white paper covers conductive and electronics 3D resins, including ESD-dissipative engineering grades and conductive matrices with CNT, graphene, silver and PEDOT:PSS payload routes. Electrical performance is system-dependent. Conductivity, ESD behaviour, semiconductive resp...

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...

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...

The 3Dresyns Wedge Method

The Wedge Method white paper presents a fast practical fingerprint for evaluating curing behaviour, optical penetration, printability and overcure tendency using a compact geometry and a short validation sequence. The wedge is useful when a full CRT package is not yet available o...
