Farsoon, Huaxiang & LEHVOSS Group: A joint effort to manufacture safety goggles to fight COVID-19

With a solid background in medical 3D printing, Huaxiang experts have been able to quickly develop, optimize and validate safety goggles within 10 days, and produce thousands of pairs of products using the Farsoon 403P production polymer systems. The main goggle frames are produced with Farsoon FS3300PA material, which offers good strength and durability; the sealing rings are made with LUVOSINT TPU material from LEHVOSS, with excellent elongation and flexibility, which ensure a better fit and improved sealing protection compared to traditional PC material.

On March 18th, the first batch of 1000 sets of 3D printed medical safety goggles were donated to the Red Cross Society of China. At the end of March, a second batch was produced and donated to domestic and overseas countries. Last week, Farsoon was contacted by an Italian hospital requiring safety goggles and, with the help of Italian service bureau Prosilas Rapid Prototyping, they will be produced locally with LUVOSINT TPU material from LEHVOSS.

Thanks to Huaxiang Group, the goggle design files can be downloaded and produced globally. The design is available in two sizes for a better fit. The goggle frame and sealing ring can be printable with Laser Sintering (SLS), Fused Deposition Modelling (FDM) and Stereolithography (SLA) technologies. The protective lens outline is also included to simplify production.

Covid-19 is a high infective virus, mainly transmitted through droplets released into the air by coughing or sneezing. To prevent infection in highly contaminated hospital environments, medical workers who are in close contact with patients must wear personal protective equipment (PPE) including masks, gloves, and respiratory systems to prevent infections transmitted through the nose and mouth.

In addition to the safety PPE equipment listed above, safety goggles are another important protection. The conjunctiva membrane, located inside the eyelid, lubricates the eyeballs and it is the only exposed mucous membrane of the body. When the eyes are open the conjunctiva membrane is also exposed, and becomes an important, but often overlooked entrance for viruses. This is why effective safety goggles provide an import aid to protect the eye area, blocking hazardous flying particles and liquid splatter from every direction to get in contact with the eye.
