Partnering with K-Line adds a new dimension to our business including allowing for much more rapid global expansion without any Capex outlays.
Marina Domracheva
CEO & Founder - 3DPredict
In 2024, 3D Predict partnered with K Line as our OEM manufacturer. I was impressed by their business approach — within just three months, we successfully completed packaging, FDA documentation, and supplier validation. This allowed us to ensure that 3D Predict doctors received high-quality aligners on time. Now, in 2025, we’re excited to announce a deeper partnership: K Line will provide 3D Predict aligners directly to doctors. This pivotal step allows us to focus fully on what we do best: developing innovative software for aligners. We look forward to bringing you even more advanced solutions for better patient care!
