## History and founding

restor3d was spun out of a [Duke University](https://www.edgepedia.org/duke-university) laboratory about eight years before 2025 reporting, founded by Ken Gall, a Duke mechanical engineering and materials science professor. Gall licensed additive-manufacturing technology from Duke in the late 2010s; the company's printers are now at least five times faster than the machine he originally used<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>.

Growth came partly through acquisition. Since 2021 restor3d has bought three off-the-shelf joint manufacturers: one making ankles, one making hips and knees, and one making shoulders<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>. A major step was the 2023 acquisition of Conformis, a personalized knee company (see below).

## Technology and products

The company combines AI-driven design software, digital surgical planning, and vertically integrated additive manufacturing to produce implants tailored to both patient anatomy and surgeon preference<sup>[5](https://www.businesswire.com/news/home/20250822868539/en/restor3d-Announces-Strategic-Investment-Partnership-with-Partners-Group-to-Accelerate-Growth-in-Personalized-Orthopedic-Solutions)</sup>. In practice, a patient's imaging scans are matched to a porous, custom-fit implant design in titanium or cobalt-chrome alloy<sup>[3](https://www.fiercebiotech.com/medtech/3d-printed-orthopedic-implant-maker-restor3d-raises-104m)</sup>.

Manufacturing begins with titanium and cobalt chrome powders (cobalt melts at 2,723°F, titanium at 3,135°F). Engineers upload designs that dictate the printers' movements, and implants are built layer by layer using laser powder-bed fusion. Planning a single implant may take weeks or months, but the printing itself can be done overnight; printers run 24/7, and a polyethylene bearing surface is added for joint movement<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>.

Cleared and launched products include:

- **iTotal Identity 3DP Porous Cementless Total Knee**: FDA 510(k) clearance in early April 2025, described by the company as the first fully cementless, patient-specific knee system<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup>.
- **Kinos Modular Stem Total Ankle System**: 510(k) clearance in late 2024<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup>.
- **Ossera AFX ankle fusion system**: after a limited release, expanded to standardized Cylinder, Dome, and Pill geometries derived from the company's patient case data, offered in standard and made-to-order options. The system uses 3D-printed titanium alloy implants with TIDAL Technology, restor3d's proprietary porous architecture designed to support osseointegration (bone growth into the implant surface)<sup>[7](https://orthotw.com/press-releases/restor3d-announces-full-commercial-launch-of-ossera-afx-ankle-fusion-cage-system-immediately-available-in-both-standard-and-made-to-order-options)</sup>.
- **Veritas Reverse Total Shoulder and Velora acetabular systems**: pending 510(k) as of April 2025, alongside plans for four fully 3D-printed product lines launching in 2025 and 2026<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup><sup> • </sup><sup>[3](https://www.fiercebiotech.com/medtech/3d-printed-orthopedic-implant-maker-restor3d-raises-104m)</sup>.

## Funding (by the numbers)

The financing record contains discrepancies between SEC filings and press figures, and both are reported here.

- **2024**: The company and press describe a $70 million Series A<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>.
- **January 2025**: A $40 million convertible-notes offering with $28,386,246 sold and 127 investors, per a Form D/A filed April 7, 2025; minimum investment $25,000<sup>[4](https://www.sec.gov/Archives/edgar/data/1723907/000172390725000005/0001723907-25-000005.txt)</sup>. Greg Anglum is named as chief financial officer in that filing<sup>[4](https://www.sec.gov/Archives/edgar/data/1723907/000172390725000005/0001723907-25-000005.txt)</sup>.
- **April 2025**: Completed capital raising totaling $38 million from existing and new private investors, including Summers Value Partners<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup>.
- **August 2025**: A total of $104 million, including $65 million of new equity from [Partners Group](https://www.edgepedia.org/partners-group), which took a significant minority stake, a board seat, and the distinction of the company's first institutional investment; $39 million came from existing shareholders, per the company's announcement<sup>[5](https://www.businesswire.com/news/home/20250822868539/en/restor3d-Announces-Strategic-Investment-Partnership-with-Partners-Group-to-Accelerate-Growth-in-Personalized-Orthopedic-Solutions)</sup><sup> • </sup><sup>[3](https://www.fiercebiotech.com/medtech/3d-printed-orthopedic-implant-maker-restor3d-raises-104m)</sup>.

The company's press figures and its regulatory filings give differing totals.

## Business and traction

restor3d operates a hybrid model: fully patient-specific implants alongside standardized devices from its acquired joint lines, which broadens the customer base beyond fully customized cases<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>. The company said it partnered with more than 520 surgeons across 740 hospitals nationwide in 2024 alone<sup>[5](https://www.businesswire.com/news/home/20250822868539/en/restor3d-Announces-Strategic-Investment-Partnership-with-Partners-Group-to-Accelerate-Growth-in-Personalized-Orthopedic-Solutions)</sup>. CEO Ken Gall told The News & Observer that its printed implants had touched more than 150 bones and been used by more than 650 surgeons<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>.

Annual revenue was approaching $90 million, with several hundred employees split between the Morrisville/RTP headquarters and a Boston office, according to 2025 reporting<sup>[2](https://www.newsobserver.com/news/business/article312145752.html)</sup>. In April 2025 the company said it was rapidly approaching positive operating cash flow, a self-reported figure without independent verification<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup>.

## The Conformis acquisition

Under a June 2023 merger agreement, Conformis shareholders were to receive $2.27 per share in cash, with Conformis becoming a wholly owned restor3d subsidiary<sup>[1](https://www.sec.gov/Archives/edgar/data/1305773/000114036123035753/ny20009601x4_defm14a.htm)</sup>. The deal brought Conformis's patient-specific knee business in-house and enabled restor3d's first cementless patient-specific knee, iTotal Identity, cleared by FDA in 2025<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup><sup> • </sup><sup>[3](https://www.fiercebiotech.com/medtech/3d-printed-orthopedic-implant-maker-restor3d-raises-104m)</sup>.

## Recent developments

The 2023 Conformis closing was followed by a rapid run of financing and product news: three off-the-shelf joint acquisitions integrated into a hybrid portfolio; 510(k) clearances for the Kinos total ankle (late 2024) and the iTotal Identity cementless knee (April 2025); full commercial launch of the Ossera AFX system in standard and made-to-order options<sup>[7](https://orthotw.com/press-releases/restor3d-announces-full-commercial-launch-of-ossera-afx-ankle-fusion-cage-system-immediately-available-in-both-standard-and-made-to-order-options)</sup>; $38 million of growth capital in April 2025<sup>[6](https://www.businesswire.com/news/home/20250404455551/en/restor3d-Secures-%2438-Million-in-Growth-Capital-to-Drive-Expansion-and-Innovation-in-Personalized-Orthopedic-Solutions)</sup>; and the $104 million August 2025 round anchored by Partners Group<sup>[5](https://www.businesswire.com/news/home/20250822868539/en/restor3d-Announces-Strategic-Investment-Partnership-with-Partners-Group-to-Accelerate-Growth-in-Personalized-Orthopedic-Solutions)</sup>. The company plans four new 3D-printed product lines by the end of 2026<sup>[3](https://www.fiercebiotech.com/medtech/3d-printed-orthopedic-implant-maker-restor3d-raises-104m)</sup>.
