Open-source 3D-printed portable MRI machine built for under $70,000 — DIY medical equipment costs less than 7% of a full-sized MRI machine’s $1.1 million starting price

The OSI2 ONE MRI scanner.

MRI machines are life-saving medical devices that can let doctors and radiologists diagnose various critical conditions, but they’re also insanely expensive. Brand-new models start at $1.1 million and could go as high as $3 million per unit or more. The Open Source Imaging Initiative recognized this limitation and has been working on the open-source OSI2 ONE MRI scanner, which had already been replicated multiple times globally. However, this portable device, which has a 3D-printed core, has a limited field strength of just 50mT (compared to the 1.5T to 3T used by full-sized units). This gave them lower spatial resolution and lower signal-to-noise ratio, but tech analyst Brian Roemmele said on X that AI can overcome this and make it usable for medical diagnoses.

BOOM! OPEN SOURCE MRI!You can now 3D-print the core of an MRI scanner.A machine that hospitals pay $1.1 million to $3.4 million for has been broken open. The OSI² ONE and its educational siblings deliver real images of heads and limbs for a fraction of the cost, using a… pic.twitter.com/BeONbIyX5oJuly 25, 2026
