תצוגה לדוגמה
חומרי עיבוד:
- Metal: 316L Stainless Steel, Ni-Ti Alloys, L605, Iron (Fe), Magnesium (Mg), Zinc (Zn)
- נירוסטה 316L is a medical-grade austenitic chromium-nickel alloy renowned for its excellent corrosion resistance and biocompatibility. With a tensile strength of approximately 485–550 MPa and elongation up to 40%, it offers durability and flexibility without brittleness. Its low carbon content enhances weldability and resistance to intergranular corrosion, making it ideal for medical implants and instruments. Laser-machined for smooth, burr-free surfaces, it minimizes tissue irritation in sensitive applications.
- Nitinol (NiTi), a nickel-titanium alloy, is renowned for its superelasticity and shape memory, making it a game-changer in medical applications. With a tensile strength of up to 1200 MPa and elastic modulus of 40–75 GPa, nitinol excels in demanding environments.
- Cobalt-Chromium Alloys (L605) are medical-grade materials valued for their exceptional strength, corrosion resistance, and biocompatibility. With tensile strength ranging from 800–1500 MPa and hardness of 300–550 HV, they ensure durability in demanding medical applications. Ideal for implants and surgical tools, they support direct tissue contact with minimal reaction. Laser-machined surfaces provide smooth, burr-free finishes, enhancing performance in sensitive procedures.
- Iron (Fe): A strong, durable metal used in some surgical instruments and structural components. Its high strength and cost-effectiveness make it suitable for non-implantable medical tools.
- Magnesium alloy: Magnesium, a lightweight (1.74 g/cm³) and biodegradable metal, is ideal for temporary medical implants like stents and orthopedic screws. Alloys such as WE43 or JDBM offer tensile strength (200–420 MPa) and controlled degradation (6–24 months), safely dissolving into non-toxic byproducts (Mg²⁺ ions). Its biocompatibility (ISO 10993) and ability to support tissue regeneration make it suitable for cardiovascular and bone repair applications. Magnesium’s elastic modulus closely matches bone, minimizing stress shielding in orthopedic uses.
- Zinc (Zn) Zinc is a promising bioresorbable metal with excellent biocompatibility and corrosion control. In medical applications, zinc-based alloys are used for stents and implants, providing mechanical strength while gradually resorbing in the body without toxic effects.
- Non-Metal: PLA, PLLA, PI, Nylon, Glass
- PLA (Polylactic Acid) A biocompatible and biodegradable polymer derived from lactic acid. Commonly used for resorbable medical implants and stents.
- PLLA (Poly-L-Lactic Acid) A biodegradable medical polymer with high mechanical strength and predictable degradation. Applied in bioresorbable vascular stents and surgical sutures.
- PI (Polyimide) A heat-resistant and durable polymer with excellent chemical and mechanical stability. Used in catheters, micro-instruments, and insulation of medical devices.
- Nylon (Polyamide): Nylon (Polyamide) is a strong, flexible material with high wear resistance and chemical stability. Ideal for precision laser cutting, it delivers smooth edges and intricate designs for medical and engineering components.
- Glass An inert, transparent, and biocompatible material. Utilized for micro-tubes, capillaries, and precision medical components requiring chemical resistance.
