Reusable Face Shield

Additively manufacturing nasopharyngeal swabs, face masks and respirator components.

Our face shield/visors are a vital piece of personal protective equipment (PPE) for dental professional safety. When the face shield/visor is used on its own, dentists, hygienists, and office staff can easily communicate with clients without visual or auditory obstruction.

When worn with a face mask, both items work together to help protect individuals from contamination of viruses like COVID-19.

Our Face Shield is a great addition to your infection control procedures.

Two-piece face shield frame made using LEXAN material.


  • Made using LEXAN material which protects against airborne droplets and aerosols
  • Comfortable to wear & breathing is easy
  • Easily cleaned with soap and water
  • Easy to attach & prevents face touching
  • Lip reading, facial recognition & social interaction
  • Reusable & longer lasting
  • Protects against the suns dangerous UV rays

There is a shortage of Face Shields at hospitals for medical responders who are testing and treating COVID-19 patients.

Medical responders need to be protected from respiratory droplets from coughing and sneezing. Even though many individuals and groups are designing and manufacturing face shield frames for these responders, many of the designs are not optimized for high-density optimized additive manufacturing and cannot be accessed locally.

The Solution

We have designed a face shield frame that is:

  • A downloadable file to enable local production using any Selective Laser Sintering (SLS) or Stereolithography (SLA) printer
  • Optimized for high-density nesting
  • Reusable design made of medical-grade nylon that is autoclavable and compatible with disinfectant cleaners
  • Comfortable due to its flexible, non-rigid, form-fitting design
  • Compatible with bonnets and bouffants for protection of the forehead and eyes due to the retention tabs


The Outcome

This face shield frame has been manufactured using medical grade nylon on our SLS ProX 6100 machine. The design is a two-part flat pack design that will clip into each other to provide structure while minimizing material usage and maximizing the density of parts that can be manufactured on an SLS machine. They can be disassembled for cleaning.

The SLA face shield design was optimized and manufactured using medical grade Accura ABS White (SL 7810) on our SLA ProX 500 machine. It was designed for flexibility, robustness, comfort, field of view and efficiency while printing. 216 frames were printed in about 70 hours, the frames were cleaned and post-processed in two days.


The company is producing face shields in two sizes: one for adults and another for youth. The shield fits most 3-10-year-olds. Both sizes of face coverings are available in a retail pack of four shields. Schools can order bulk packs in quantities of 50 units for teachers and staff and also for elementary students.

Without a vaccine or known treatment for COVID 19, a system of good classroom hygiene, frequent hand-washing and use of a face shield is the most responsible approach to safely reopening schools this fall.

We are proud and grateful for the opportunity to be the premier solution for school districts as they reopen their doors with our PPE protecting children across the country. The modern design and high-end LEXAN™ shatterproof material is the perfect solution for education staff and students to comfortably wear an effective face cover for hours without being distracted.


Ventilator Splitters

The COVID-19 Pandemic is pushing the world’s availability of ventilators to the limit.

In response, our team of doctors designed this FDA approved for emergency use 3D printed ventilator circuit splitter in case we run out of ventilators.


The rapid spread of SARS-CoV2 throughout the world has put an unimaginable strain on the healthcare system. Patients are at risk of facing the consequences of not enough ventilators, which in dealing with respiratory failure is fatal. This is a last resort, emergency-only device for use if ever faced with a critical shortage of ventilators.

The concept of ventilator sharing to our knowledge was first written by Dr. Neyman and Dr. Irvin in 2006 (Ac Emergency Medicine 2006). They demonstrated that by using T-tubes and adapters, a ventilator circuit could be divided such that four simulated patients could share a single ventilator in emergency circumstances. Although only simulated in the original article, this technique was successfully used by Dr. Menes in the 2017 Las Vegas shooting mass casualty incident. This technique saved the lives of patients, buying time until more ventilators could arrive.

Some hospitals do not have the T-tubes or other parts readily available to setup a ventilator for multiple patients. This free 3D printed part can be used in such situations.

Our goal is to have an easily printed 3D part so that anyone in the world, who may need it in dire circumstances, can use it to save live.



2-4% of all COVID-19 patients will require mechanical ventilation.



The USA has approximately 160,000+ ventilators. Some projections suggest we will need 600,000+ at the peak of the COVID-19 outbreak.


The Need

A ventilator splitter is a device that allows a single ventilator to support two or more patients during this crisis. Approximately 2.4% of all COVID-19 patients in this pandemic will require mechanical ventilation.


The Solution

The ventilator sharing concept was first written by Dr. Neyman and Dr. Irvin in 2006 (Ac Emergency Medicine 2006). By using T-tubes and adapters, a circuit could be divided so four patients can share a single ventilator in an emergency. One group, has released an open-source file for emergency POC uses along with flow limiters when pairing different patients (body weight, lung compliance, etc).



The Outcome

Additive manufacturing presents the opportunity to rapidly produce splitters for hospitals. We have several sterilizable and biocompatible materials available on all of our systems that can be used to print these parts along with several ISO 13485 certified facilities that can produce medical parts.
