Application of 3D printing technology in the medical industry

The 3D printing industry has been a leading high-tech in the last few years. As well as being widely used to protect ancient cultural relics in aerospace, manufacturing and other fields, the 3D-printing technology is continuously released in medical industry. The value of the technology is limitless. Here are the details:
Medical models and surgical guides can be customized using 3D printed medical models

To create a medical model, you can perform a three-dimensional model based on CT or MRI images of the patient before the operation. You then print it using a 3-D printer. The main purpose of a 3D printed model is for the doctor to be able to visualize the three dimensional structure of the surgery site before the procedure. This allows the doctor to plan the surgical plan. This is especially useful for complex surgery. It reduces the risks of surgery and increases the success rate.

Applications of 3D Printing in Dentistry

Dental clinics, laboratories and dentists need to take into consideration the cost of dental restorations and treatments. To improve efficiency and lower costs, many forward-thinking dental clinics have adopted digital dental technology. Recently, software-based dental restorations have gained popularity. Digital dental technology coupled with 3D printing offers high precision and efficiency at a low cost.

Applications of 3D Printing in Medical Device Manufacturing

The manufacturing of medical devices is similar to other products. For the verification of design, prototypes must be produced during the product development phase. The metal 3D-printing technology has expanded beyond prototypes in the medical device field to handle complex manufacturing tasks. In order to repair an anterior cruciate knee ligament injury, the doctor first has to remove any remaining anterior ligament and then precisely replace the graft. In order to achieve accuracy and minimize invasiveness, doctors must use a sophisticated and specialized surgical tool. The nickel-chromium alloy that is used to make this surgical tool is difficult to work with. Traditional machining is expensive and takes a lot of time. In this situation, metal 3D-printing technology is more suitable for manufacturing.

Use of 3D printing for manufacturing medicines

Three-dimensional printing has an impact on pharmaceuticals in four ways: first, it allows for personalized customization of active ingredients; second, it allows patients to have personalized treatment plans. This layer by layer printing method allows the different coatings to tightly combine with each other, so that a patient can swallow only a few tablets or smaller ones. The third aspect is the ability to customize the shape. 3D-printing technology can be used to create various shapes that are appealing to children who do not like taking medicine.

The Main Preparation Methods of 3D Printing Metal Powder

3D printing represents a new form of printing technology. 3D printing metal powder, the most important material for 3D-printing metal parts, is 3D printing. The main 3D powder materials currently available are nickel-titanium alloy powder Steel, stainless, industrial, steel, bronze, titanium, nickel-aluminum, and cobalt-chromium allision, etc.
3D printing of metal powder requires good plasticity.

Three types of preparation for 3D printing metal powder are available: reduction method, electrolysis, grinding method, and atomization method. The two most common pulverizing techniques in China today are the argon-atomization method or plasma rotating electrode.
1. Argon atomization
The argon atomization method uses the fast-flowing argon gases flow to impact the metallic liquid, then break it into small particles and finally condense into a solid powder.

2. Method using a plasma rotating electrode
Plasma state is also known as the fourth state. The process of plasma rotating electro atomization (prep) is simple: The metal or alloy is made into a consumable electrode. The end of the consumable electrode melts in coaxial plasma heating source to create liquid film. The liquid film is then thrown out at high speeds to form droplets. Under the action shear stress, the molten liquid droplet is broken down further and cools to become spherical powder.

The following are some of the benefits of plasma rotating electrode metal powder:

High sphericity with a smooth surface and high loose densities, which means that the uniformity of powder spread is excellent and printing products have a high density.

What are the commonly used materials for 3D printing?

The rapid advances in science and technology, as well as the widespread application of 3D printer technology, are slowly changing our lives and working lives. It is not easy to ignore the issue of 3D printing materials. This topic is also very popular with many people.
FDM 3D Printing Materials
FDM technology uses the same stable and strong thermoplastics as injection molding and CNC machining. FDM thermoplastics may be used in applications that require high fit tightness, toughness, and environmental resistance. They also have special properties such as biocompatibility and VO flammability.
PolyJet 3D Printing Materials
PolyJet 3D printers make use of a photosensitive material that mimics a wide variety material properties. This includes transparent and rubber-like materials, as well as high toughness. Digital Materials increases material options by mixing multiple base resins to make hundreds of material combinations. Get greater product fidelity through full color capabilities, Shore values and other properties.

SAF 3D printing materials
SAF technology uses an HAF (High Absorbent fluid) that is infrared-sensitive to fuse polymer particles together and build the part layer after layer. It employs Big Wave’s proprietary powder management technology to evenly distribute the powder over the entire surface of the printer. A piezoelectric industrial printhead then jets liquid into each area to create each layer. The part is printed by heating it with infrared light.
