AMT is supplying material to help manufacture medical PPE during COVID-19 pandemic
We are proud to announce that we will be open for business for those clients or personnel who are interested in aiding the government and medical practices with the shortage of PPE during the period of this global pandemic.
In this DIY tutorial video, Milo shows how to create a ‘gang mold’ using Ecoflex™ 00-35 silicone to cast multiple TASK™ 8 resin respirators. The result are multiple respirators which are durable and long lasting. TASK™ 8 is a high-temp resin which can be cleaned using an autoclave.
The original model file for the respirator body can be found here: https://www.thingiverse.com/thing:425…
The model file for the gasket mold can be found here: https://www.thingiverse.com/thing:425…
A mold is made of 3D printed respiratore using Ecoflex 00-35 fast setting silicone. Ecoflex 00-35 is an extremely soft and stretchable silicone rubber. After demolding, TASK 8 liquid plastic resin is poured into the mold. TASK 8 has a higher heat resistance than other urethane resins, making it suitable to be disinfected at temperatures up to 130°C.
A gasket of Ecoflex 00-35 silicone is poured into a 3D printed mold. The gasket is adhered to the resin respirator using Sil-Poxy silicone adhesive to create a proper seal onto the face. Straps are created using a rubber band or other elastic band.
These are attached to the respirator. A piece of HEPA fabric is inserted into the front of the respirator to complete the respirator.
