Systems and CollPlant Enter into Co-development Agreement to Deliver Bioprinted Solutions for Improved Breast Reconstruction Treatments

HILL, South Carolina and REHOVOT, Israel, June 22, 2021 - Today, 3D Systems (NYSE:DDD) and CollPlant Biotechnologies (NASDAQ:CLGN)

announced they have signed a co-development agreement for a 3D bioprinted regenerative soft tissue matrix for use in breast reconstruction

procedures in combination with an implant. The soft tissue matrix is intended to support the lower portion of the breast while expanding

the implant pocket and providing increased coverage of the implant. Using 3D bioprinting, these matrices can be designed to match the

patient's anatomy to support the breast implant.

to the World Health Organization, 2.3 million women were diagnosed with breast cancer globally in 2020, of which, a large majority required

partial or full removal of breast tissue. Survival probabilities are 90% or greater due to highly effective treatments which is increasing

the focus on delivering improved options for reconstruction. The majority of breast reconstruction procedures use soft tissue matrices

derived from human cadavers or animals. These sources are associated with supply shortages and batch-to-batch variability, as well as

the possibility for eliciting immune response which impacts healing.

this co-development agreement, 3D Systems and CollPlant - with combined expertise in 3D printing, healthcare, bioprinting and bioinks

- will develop 3D bioprinted soft tissue matrices using rhCollagen. The 3D bioprinted soft tissue matrix product in development

is designed to meet the required physical and mechanical properties while promoting cell infiltration and proliferation by using bioink

formulations based on rhCollagen that promote tissue regeneration. The companies believe their efforts will result in tissue matrices

that offer superior performance, consistency and safety due to their plant origin and identical match with natural human collagen which

does not elicit an adverse immune response in humans.

January of this year, we announced our intention to increase the investment in regenerative medicine and focus on developing and commercializing

solutions to change how healthcare is delivered and bring substantial benefits to patients," said Dr. Jeffrey Graves, president

& chief executive officer, 3D Systems. "Through this project we're embarking on with CollPlant, we're exploring

a novel application that could offer a new reconstruction treatment for breast cancer survivors. It's inspiring to be involved

in a project that has the potential to have such a positive impact on the human condition."

joined forces with 3D Systems to offer a regenerative soft tissue matrix that may significantly increase the addressable market for soft

tissue reinforcement in breast implant procedures. A regenerative solution can increase safety, eliminate product variability, and enhance

results by promoting new tissue growth," stated Yehiel Tal, chief executive officer, CollPlant. "We are pleased to deepen

our collaboration with 3D Systems as part of CollPlant's strategy as a leader in regenerative medicine."
