China3D printingNet, June 15th, in recent years, we have been paying attention to the technology of additive manufacturing. I used to think that ceramics are only used to make high-end pottery. Although this is true for many applications, hard non-metallic materials have strong compressibility and can withstand high temperatures and chemical corrosion. According to the SmarTech analysis report, the ceramic additive manufacturing market is expected to reach 48 in 2030. One hundred million U.S. dollars.

Dutch company Admatec focuses on advanced ceramics and metals3D printing, Now introduces bioabsorbable ceramics into its product portfolio. CAM Bioceramics is an ISO 13485:2016 certified supplier of medical-grade ceramics and is supporting Admatec to introduce new materials into the medical and dental fields through its Admaflex printer3D printingChance.
“As a supplier to the orthopedics and dental market, CAM Bioceramics recognizes3D printingWill play an increasingly important role in many patient treatment plans. C. Hogeboom, CEO of CAM Bioceramics, said that calcium phosphate-based bone reconstructions will play an important role in the next generation of medical device solutions due to their biocompatibility. “As one of the market leaders in this field, CAM Bioceramics actively cooperates with3D printingExperts collaborate and promote3D printingSolution development. “
Advanced ceramic materials have great utility in medical applications, especially in the manufacture of surgical instruments and implants.Depend on3D printingYes, patient-specific implants made of bioabsorbable and biocompatible ceramics are usually used in cranio-maxillofacial and semi-maxillary surgery because they can be absorbed by the body. Natural bone tissue will eventually replace the implant, so there is no need to remove it with autogenous bone (collected from the patient’s own body) in the future, which can cause pain for the patient.
Although tricalcium phosphate or bone ashes are commonly used in this application, biologically active hydroxyapatite (a mineral component that is chemically similar to bone) provides the body with more healing time because it takes longer for the body to absorb it. By cooperating with CAM Bioceramics, Admatec is now able to use its Admaflex DLP 3D printingThe machine uses commercially available hydroxyapatite slurry materials to make implants for patients.
Bioabsorbable implants can be made into very well-defined pore structures and geometries.In addition, through3D printing, Which means that the optimal geometry can be defined for the implant so that it fits the patient perfectly.By using both dense and porous structures in bone tissue engineering, it can promote the in-growth of bones in nearby tissues of the human body, and3D printingIt is very suitable for this bill because it can produce interconnected stents with clearly defined dimensions and geometries.
“Using hydroxyapatite, we can manufacture patient-specific, bioabsorbable implants that have a defined pore structure and geometry.” Admatec said in a press release, “With the help of light-based implants provided by Admatec Engraved additive manufacturing technology has successfully printed a combination of functionally graded ceramic materials, such as the dense and porous structure in a single semi-maxillary structure.”
Admatec suggested that its technology can effectively print complex channels, geometric shapes, lattice and honeycomb structures with wall thicknesses and features in the range of 100μm. Its batch-oriented process can print larger implants, and its multi-part printing software can help print different geometric shapes for smaller implants at the same time.

With its latest bioresorbable ceramics, Admatec can provide more customized solutions for medical device manufacturers. For example, the company is now working on multi-material DLP 3D printing, Where a combination of zirconia and hydroxyapatite is used to print a composite implant of the mandible.
A large bone defect caused by a tumor or severe trauma cannot be cured on its own without help. One possible solution is to use a 3D cage made of high-strength zirconia or another ceramic material that can support the area during healing. . The cage will be paired with the implant, which has the characteristics of an internal bioabsorbable ceramic (such as hydroxyapatite), and because they are biocompatible, both can stay in the body.
