Liqcreate Creates Flame Retardant Polymer for High Temperature Applications

Dutch independent 3D printing material manufacturer Liqcreate has developed an engineering 3D printing resin called Liqcreate Flame Retardant HDT, which features high temperature resistance in combination with a UL94 V0 flammability rating. This rating is essential for a wide range of engineering, mobility, consumer goods and electronics applications.

The resin is an extremely rigid off-white photopolymer that can be processed on most resin-based 3D printers. The resin is compatible with digital light processing (DLP), liquid crystal display (LCD) and laser-based 3D printing systems operating in the range 385-420 nm. The 3D printing parameters for multiple printers can be found on the Liqcreate website.

Parts made with this resin can withstand high temperatures without posing a fire hazard due to its self-extinguishing capabilities. With an HDT-B value of 257°C / 495°F, it is well suite for high-temperature applications. Also, with its UL94 V0 rating, it is suitable for applications like interior parts in cars, airplanes, trains and electronic devices. In addition, it can be excellent for tooling manufacturing aids, connector housings and covers.

Flame Retardant HDT Resin for Aviation and Mobility Applications

Liqcreate Flame Retardant HDT resin was tested by the UL94 organization and confirmed in their report that the product has the following flammability rating: UL94 V0 at 3mm. In addition, Liqcreate conducted an internal test method guided by the FAR 25.853 (Appendix F, Part I (a) (1) (ii)12 seconds Vertical Burn) testing methods which resulted in a pass at 1.5 mm thickness. These tests are a good basis for further development of applications within the aviation and mobility sector. Additional tests might be required to fully comply with the FAR 25.853 in aviation or the EN-45545 for train parts.

OEM Possibilities for Flame retardant 3D-Printing Resin

For OEM partners, the resin can be rebranded and optimized for different use cases and 3D printers. Alongside its branded resin range, Liqcreate also provides a custom development service, offering nonstandard formulas for specific applications. Through this service, customers can request the development of a polymer possessing precise characteristics, which impact its printing speed, as well as the properties of the resulting part.

As an independent resin manufacturer with R&D facilities, Liqcreate says it is capable of rapidly scaling its production of custom-made resins where needed. Moreover, the standalone nature of the company ensures there is minimal competition or conflict when working with 3D printer hardware manufacturers. This is said to ensure that the firm can work quickly, and get resins to market in quantity, avoiding any issues or delays that would keep clients waiting.
