CEO

Lattice Medical is a French company whose main mission is to design resorbable tissue reconstruction implants using 3D printing. The company’s first application is for breast reconstruction following breast cancer.

Innovating for health through 3D printing

With its expertise in the development of medical devices, Lattice Medical created its Lattice Services brand in 2020, with the aim of making 3D printing more accessible and suitable for the healthcare sector.
Specialising in the marketing of medical-grade biomaterials, the brand also offers tailor-made support to effectively integrate additive manufacturing into R&D projects, from formulation to industrialisation.
With its in-depth knowledge of regulatory requirements and technical expertise in medical polymers, Lattice Services is positioned as a preferred partner for healthcare players seeking to innovate in full compliance.
His ambition: to accelerate medical innovation through biomaterials and 3D printing.
Lattice Services began by developing resorbable and implantable filaments to meet the internal needs of Lattice Medical, gradually creating several products in this range.
Today, Lattice Services also offers filaments suitable for skin contact, filaments loaded for advanced technical applications, and customised solutions through custom extrusion. All filaments are produced in our laboratories in northern France.
Each filament is designed to combine quality, traceability, safety and compatibility with the R&D projects of players in the medical sector.


Lattice Services also benefits from solid in-house expertise in the development of medical devices.
This experience enables it to offer healthcare industry players comprehensive support for the design and production of 3D-printed medical devices. Services include formulation, prototyping, production and industrialisation. In-house laboratories also enable the mechanical performance and biological compatibility of materials to be tested, ensuring reliability and safety at every stage of development.
Commercialisation of medical-grade biomaterials
Support for healthcare companies wishing to integrate 3D printing
Material characterisation
The alliance between the teams at Lattice Medical, experts in implant development, and Lattice Services, specialists in materials for medical 3D printing, has led to the creation of MATTISSE. MATTISSE is a bioresorbable, 3D-printed tissue engineering chamber (TEC) designed for women who have undergone a mastectomy following breast cancer.
This bioprosthesis consists of two parts:
A porous base for attaching autologous tissue
A dome that allows you to create the desired volume and shape
This bioprosthesis aims to offer a less invasive and simplified breast reconstruction procedure. During the operation, a flap of the patient’s own fat tissue is removed and attached to the base. Thanks to the mechanical protection provided by the dome, the fat can regenerate and grow within the TEC, thereby recreating breast volume. MATTISSE is currently undergoing clinical trials to assess its safety and performance.
A truly emblematic use case, this project illustrates Lattice’s ability to support healthcare professionals in the manufacture of innovative devices, from raw materials to the final implant.

LATTICE SERVICES is above all a team of multidisciplinary experts who are determined and passionate about applying their expertise to meet the challenges of tomorrow. Our varied experiences and profiles have enabled us to develop a keen sense of listening, allowing us to turn every future project into a concrete product.
