3Dresyns materials named in Johnson Matthey patent applications
Patent-literature traceability.
3Dresyns materials are named as components in the worked examples of two Johnson Matthey patent applications. This page is documentary evidence of that naming, not an endorsement, a granted patent or a performance claim.
Evidence in numbers
What this page is (and is not)
This is not a peer-reviewed evidence page. It is a patent-literature traceability page. It documents that 3Dresyns materials, supplied by Resyner Technologies, are named as components in the worked examples of two patent applications filed by Johnson Matthey.
Each reference here was checked against the full text of the patent application itself, not against a secondary listing or the Press hub. The wording, the role of each material and the legal status are reported as they appear in the applications.
Both documents are patent applications, not granted patents. In each one the 3Dresyns materials are named as components in disclosed examples or formulations, while the claimed invention is something else (a carbon dioxide sorbent process in one case, a bittering agent in a printed object in the other). Naming a material in an example is not the same as that material being the claimed invention, and it is not an endorsement of 3Dresyns by Johnson Matthey.
A minor note on company name: the applications cite the supplier with different legal suffixes (Resyner Technologies S.L. in the US application, Resyner Technologies Ltd. in the CN application). These refer to the same company, 3Dresyns / Resyner Technologies; the page reproduces each wording as written.
The patent applications
US 2023/0390736 A1: light blocker LB1 in a CO2 sorbent example
This Johnson Matthey patent application (published December 2023) describes a process for removing carbon dioxide from a hydrogen-containing gas using a shaped sorbent made by vat photopolymerisation, that is layers of photopolymerised resin containing zeolite molecular-sieve particles, printed by digital light processing.
In the worked examples, the light blocker LB1, supplied by Resyner Technologies S.L., is named as a component (about 0.5 percent by weight) of one of the example sorbent formulations. LB1 limits over-penetration of light during printing to improve feature reproduction. In these examples the base photopolymer is a separate third-party product (a development resin from Tethon Corporation), so the only 3Dresyns material named is the LB1 light blocker.
LB1 is named as a component in a disclosed example, not as the claimed invention. The claims concern the carbon dioxide sorbent process and the shaped sorbent in general, and do not name LB1. The document is a published patent application, not a granted patent. Naming LB1 is not an endorsement of 3Dresyns by Johnson Matthey and does not validate LB1 performance; the carbon dioxide capture behaviour reported belongs to the zeolite sorbent and the printed structure, not to the light blocker.
CN 114096393 A: HDT1 and other 3Dresyns resins as printing feedstock
This Johnson Matthey patent application publication describes a build-up manufacturing method that distributes a bittering agent within a cured 3D-printed polymer, for example to make in-ear hearing-aid shells taste bitter and deter ingestion by children or pets. The claimed invention is the bittering agent in the printed object.
In the worked examples, several Resyner Technologies resins are named as the photopolymer feedstock used to print the parts: HDT1 (a complete vat-photopolymerisation resin made of FT1 photoaccelerant, LB1 light blocker and resin matrix), ENG1, and F blue, each described as supplied by Resyner Technologies. The Fine Tuners FT1 (photoaccelerant) and LB1 (light blocker) are named as components of those resins.
These resins are named as the printing feedstock in disclosed examples, not as the claimed invention. The claimed invention is the bittering agent distributed in the resin, not the 3Dresyns resins. The document is a patent application publication, not treated here as a granted patent, and the wider patent family has, according to public patent records, been withdrawn or abandoned in several jurisdictions. Naming the resins is not an endorsement of 3Dresyns by Johnson Matthey and does not validate their performance.
Which material is named where
Separating the named 3Dresyns materials from the claimed inventions
| Material | What it is | How it is named in the applications |
|---|---|---|
| LB1 (Fine Tuner) | Biocompatible light blocker for SLA, DLP and LCD printing | Named as a light-blocker component controlling light penetration in disclosed example formulations (US and CN) |
| FT1 (Fine Tuner) | General-purpose photoaccelerant and photoreactivity modifier | Named as the photoaccelerant component of the example resins (CN) |
| HDT1 | Ultra hard and rigid, high heat-deflection-temperature resin | Named as a complete example printing resin (FT1 plus LB1 plus matrix), supplied by Resyner Technologies (CN) |
| ENG1 | Tough engineering functional resin (monomer-free version available) | Named as an example printing resin, supplied by Resyner Technologies (CN) |
| F blue | Resyner Technologies development formulation (resin matrix plus FT1, blue) | Named as an example printing formulation, supplied by Resyner Technologies (CN). No dedicated catalogue page |
| Claim scope | The legal scope of each application | Belongs to the applicant, Johnson Matthey, not to 3Dresyns. The 3Dresyns materials are named components, not the claimed invention |

Patent scope and legal note
A patent application is not a granted patent, and a named material is not the claimed invention
The cited Johnson Matthey documents are patent applications, not granted patents unless otherwise stated. 3Dresyns materials are named as components in examples or formulations described in the applications. This does not mean that 3Dresyns materials are the claimed invention, that Johnson Matthey endorses 3Dresyns, or that the patent applications validate product performance. Patent citations are presented only as documentary evidence that the materials were named in disclosed technical examples.
A patent application is not a granted patent. A named material is not the claimed invention. A patent citation is not a license, an endorsement, a commercial relationship, a validation of performance or a statement of freedom to operate. Nothing on this page is legal advice.
3Dresyns materials and additives are supplied as professional manufacturing materials and are not marketed here as finished medical devices. The content, scope and legal status of any third-party patent or patent application remain the responsibility of the respective applicant or patent owner. Users are responsible for verifying the current status of any cited document.
