At the National Technical Institute for the Deaf, a student wears the BEclear mask with two other staff who smile to each other.

To meet the immediate needs of the COVID-19 pandemic, academics and industrialists from Buffalo, NY joined forces with the international e-NABLE movement to create reusable open source emergency personal protection equipment.

We hope to accelerate universal adoption of masks during public health emergencies.

Models & Versions

We have created four reusable designs with innovative features, including several transparent masks with filtration positioned under the chin to enhance communication for the Deaf community as well as professionals who rely on facial communication. We have also documented production processes that can be used for localized fabrication and distribution.

User Guide

For each design, we have collected resources to support users regarding assembly, care, sanitization, use, and fit.

Production and Distribution

Each of our mask designs utilizes a different production process. BEmask 1.6 is 3D-printed. The Harbec Mask is Injection molded. The BEclear Mask is produced by vacuum forming. The BEclear mask is hand-crafted from a recycled beverage bottle. We are locally fabricating some of these devices ourselves and we encourage fabricators to adopt and develop these designs to suit their own purposes and capabilities.

Recycling / Reuse


There are many things to consider with personal protective equipment that influence efficiency and safety. We have researched materials and filter media, the correct fit on an individual’s face to make a good seal, and the sanitization practices. BE masks have undergone clinical fit tests in local hospitals and comparative pre-NIOSH filtration tests with N95 masks. Our masks have been shared on the NIH 3D Print Exchange, managed by the VHA

The BE team includes biomedical engineers, health and safety administrators, 3D print specialists, filtration experts, and doctors who are committed to researching sanitization guidelines and testing the use and reuse of masks and filters.

Different designs have undergone different levels of testing. For details, check the mask pages below:

The 3D printed mask information presented here is intended to assist the general public during the current global pandemic related to COVID-19 and the related nationwide shortage of personal protective equipment. Please be aware that this mask design is not intended to replace standard protective equipment such as N95 masks or surgical masks when that equipment is available. The use of these 3D printed masks has not been fully tested and has not been approved by federal or state authorities. The individuals associated with developing and producing this mask design assume no liability and make no representations, warranties, or guarantees regarding the safety, efficacy, or appropriate use of these masks in any particular situation. Each facility should test each batch of masks prior to relying on them for protection. Use of this information for any purpose is at the maker’s and user’s own risk.
