Give feedback on prototype demo splitter. Join FB live session on Saturday 11am IST: URL for event tomorrow

Doctors & Hospitals: Given upcoming Covid surge, some doctors are expanding their ventilator capacity via 3D printing valves and splitters. See pics and videos of such tests below. Please fill out the short form below if you want to print such items with local help (you don’t need to be in India, as long as we find 3D printing facilities in your city, we will connect you).

We already have names of 3D printers interested in helping in some cities in India: Ahmedabad, Bangalore, Chennai, Coimbatore, Gurgaon, Indore, Kolkata, Mumbai, North Goa, Pune, Surat, Udaipur, Unnav, Vadodara and Vishakapatnam. We will add more everyday.

3D Printing companies: If you have access to a 3D printer and can help print valves and ventilator splitters for your local hospital, then please fill out the form below. We will contact you when there is a hospital looking for help in your city.

Types of 3D Printed Materials to help with Covid Surge


3D printing a missing or broken valve can might allow you to use ventilators that you could not use otherwise. With supply chains broken this is an easy way to make sure you can use all your ventilators.

Ventilator Splitter Design & Reference
This design is for a four way splitter for a ventilator. You can download CAD files here.

The team at Aster CMI Hospital Bangalore has been 3d printing and testing splitters for ventilators. See the pictures and videos from their tests below

Two way splitter in action:


  1. What kind of materials have you been printing on?
    We have been printing on medical grade plastic so far. But it should be possible to print on regular plastic as well.
  2. Can these be sterilized?
    Yes, with ETO.
  3. How long will these last?
    We don’t know. We have not used it enough to know this.
