3Dresyns biocompatible resins are custom designed and personalized for different types of 3D printed medical devices, such as implantable, durable and non-durable, biodegradable and bioabsorbable, medical devices.

3Dresyns biomaterials are custom designed to meet specific and the most demanding mechanical and biocompatibility* requirements for different types and classes of medical devices, including bioprinted implants and in situ 3D printed tissues, without the typical in vivo cytotoxicity problems caused by the existing biocompatible raw materials.

About biocompatibility 
3Dresyns biocompatible and ultra safe Monomer Free MF bioresins are unique and the first, and only "monomer free" resin system in the marketplace, for printing a broad range of non-cytotoxic* durable and non-durable, biodegradable and absorbable, biomedical devices.
3Dresyns has the necessary skills and experience to design and customise 3D printing resins and processing protocols for different biomedical applications and printing specifications, including 3D printed implantable devices for controlled drug release, and other specialty durable and non-durable, biodegradable and bioabsorbable, biomedical applications.
3Dresyns also custom designs 3D printable biocompatible materials for bone regeneration in dentistry, providing excellent protection from gum overgrowth, and safe bone resorption. These bioresins can be designed to have certain flexibility and elastic memory, to confer excellent protection during bone regeneration.

3D resins for implantable medical devices

The development of ultra safe 3D printed implantable medical devices is now a reality with our bioresins, which have been designed to diagnose, treat, repair, and even replace tissues and organs in the body or enhance their functions. They can be bio-based, synthetic, monomer free, or monomer based, or a combination of them.

3Dresyns bioresins used in 3D printing implantable medical devices can be divided by application:
  • Biomedical 3D bioresins
    • Biomedical 3D printed bioresins are biocompatible photopolymers based on bio-based or synthetic, or combinations of both, which are durable, non- biodegradable, or non-durable or biodegradable. Durable, non-degradable, 3D bioresins are designed to have good physical and mechanical properties for a long time in a biological environment. On the other hand, non-durable, biodegradable, 3D printed bioresins degrade in the biological environment, where the implant is absorbed and/or eliminated with the normal metabolism of the human body. Biomedical 3D printed bioresins are being used for repairing cardiovascular stents, soft and hard tissues
  • Biomedical 3D printed metals via Direct or Indirect Additive Manufacturing
    • Biomedical 3D printed metals refer to metals, such as stainless steel, titanium, titanium alloys, cobalt-chromium-molybdenum alloys, and other exotic metals. They are typically used for surgical implants, for bone and joint substitutes, spinal implants, cardiovascular implants, etc. They exhibit high mechanical properties and chemical resistance. Its usage and design requires maximum control since they are prone to cause metallosis
  • Biomedical 3D printed ceramics via Direct or Indirect Additive Manufacturing
    • Biomedical 3D printed ceramics are biologically inert "bioinert", such as alumina, zirconia, and carbon, or biodegradable "bioactive", such as tricalcium phosphate. Bioinert ceramics are stable and inert, whilst bioactive ceramics form strong chemical bonds with tissues through chemical reactions in the body. Biodegradable bioactive ceramics can be absorbed by the body and promote bone regeneration, such as tricalcium phosphate ceramics. Biomedical ceramics can be used to make artificial hip joints, artificial bones, valves, etc. The main limitation of biomedical ceramics is their intrinsic fragility
  • Biomedical 3D printed composites
    • Biomedical 3D printed composites include coatings, bone and teeth cements. Biomedical composites are used for repairing and replacing human tissues, organs, and for enhancing their functionality for the manufacturing of artificial organs
  • Biorenewable 3D printed resins
    • Biorenewable materials are used for preserving the maintenance and as replacement of human dynamic processes. They are used in artificial heart valves, skin masks, bone restorations, vascular restorations, etc. They are made from natural biological tissues through special processing. 3Dresyns achievements in medical 3D printing materials, include a full range of especially resins for printing scaffolds for bioprinting and tissue engineering. Metamaterials with tough and elastic properties can be custom designed for bone, skin, tissue & cartilage tissue engineering applications. Implants can also be custom designed with control biodegradability, bioabsorption and porosity; these include biomimetic materials created from bio-based sources and building blocks, metamaterials used for functional tissue scaffolds in bone tissue regeneration, orthopedic implants, intelligent 4D printed materials with shape memory for bone regeneration, and other biomedical applications

Typical 3D Printed Implantable Medical Devices
3D printed implantable medical devices  can be used in different regions of the human body. Typical products include orthopedic implants, artificial joint prostheses, vascular stents, heart valve prostheses, and human organs:
  • Orthopedic Implants
    • Biocompatible 3D resins for artificial bone scaffolds based on tricalcium phosphate can be custom designed for printing prosthesis and orthopedics.
  • Artificial Joint Prostheses
    • Biocompatible 3D resins for joint replacement surgery can be personalized and custom designed to meet the overall biocompatiblity and quality requirements of each sort of phostheses 
  • Vascular Stents
    • Vascular stent interventional therapy is used for the treatment of cardiovascular diseases. Photocurable bioresins can be custom designed for printing durable and bioabsorbable vascular stents. As example, 3D printable composites based on biocompatible bioresins and graphene can be designed for printing vascular bio scaffolds with controlled drug release
  • Heart valve Prostheses
    • Biocompatible 3D resins can be customised for printing heart aortic valves, including mechanical, intervention, biological, and tissue valves
  • Human Organs
    • 3D printing technology has a wide range of biomedical applications, such as the printing of tissues, including livers, kidneys, skin, etc

3Dresyns experticise include the development of biomaterials for the most demanding applications, including 3D printed dental biocomposite implants, cardiovascular devices (heart implants), in vivo direct printing, and orthopedic implant devices.

*Note: biocompatibility depends on the polymer conversion and removal of residuals and byproducts from the prints, which need to be properly post processed to ensure their biocompatibility. For more info read:
