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. Its value alone has an unlimited market. 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 three-dimensional modelling based on CT or MRI images of the patient before the operation. You then print out the model using a 3-D printer. The 3D printed model allows the doctor to visualize the three dimensional structure of surgical site in advance of the operation. It helps plan the surgery. 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 stage. 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 appropriate 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. The layer-by-layer method of printing allows for the tight combination of different coatings so that the maximum dosage of a substance can be packed into a small tablet that can be swallowed by the patient. 3D-printing technology can be used to create various shapes that are appealing to children who do not like taking medicine.

What is 3D Printing Metal Powder?

Metal 3D Printing is a 3D technology that uses metal powders to directly print metal parts. This is also called Selective Laser Melting. 3D printed metal powders need to have good plasticity.
Metal powders are used in 3D printers for stainless steel, aluminum, cobalt chromium alloys, copper alloys, titanium alloys, and nickel alloys. Iron base alloy is the largest and most important metal material in engineering technology. It is widely used for the creation of complex structures.
The performance of the final product will depend on the type of metal powder and 3D printing method used.

Stainless-steel powder
Low-cost metal printing materials can be quickly and economically used for small batches of complex industrial components manufacturing.

Aluminium alloy powder
AlSi12Mg is the most commonly used aluminum alloy in metal 3D printers. Aluminosilicate 12 (lightweight additive) is used to create metal powders with excellent thermal properties. Combining silicon and magnesium gives aluminum alloys greater strength and stiffness. They are suitable for thin walls, complex geometry, and applications with high thermal properties. Aluminum alloy is an industry staple due to its low density, high specific strengths, close to or greater than high-quality steel and good plasticity. 3D printing of aluminum alloy has been shown to produce compact parts with small structures, similar to casting, or better than casting molding parts. The cost of 3D printing is also reduced by as much as 30% compared to traditional process parts.

Cobalt chrome alloy powder
It is used for printing all kinds of artificial joints, plastic surgery implants and other dental procedures.

Copper alloy Powder
Copper has excellent thermal conductivity as well as electrical conductivity. It can be used in thermal management applications to combine design degrees for complex internal structures and conformal cool channels.

Titanium alloy powder
It is widely used within the aerospace industry. 3D printing offers many benefits. One example is the ability to replace a solid body with a complex, reasonable structure. The result is a product that is lighter and has better mechanical properties. This will not only reduce costs but also allow for lighter production.

Nickel alloy pulver
Nickel alloy's oxidation and corrosion resistance make it ideal for harsh environments such as high temperature and high stress. To protect the internal nickel alloy from corrosion, the alloy's surface will passivate when it is heated. Nickel alloys have good mechanical properties across a wide range temperature ranges.

Can powdered materials be used in 3D printing?
3D data can be used to control laser beams of high energy to melt metal matrix locally and then sinter it to form solid parts.

How do you make 3D printing metal powder?
Solid-state reduction, electrolysis and chemical are the most common methods to produce metal powders.
Many manufacturers use electrolysis or reduction methods to make elemental metal particles. However, they are not suitable in making alloy powders.
Alloy powder can be made using the atomization method.
Another way to make powdered metals is by electrolysis. Different metals can either be made spongy, or powdered by selecting the right electrolyte composition and temperature, concentration, as well as current density. These can then be washed or dried and reduced to a powdered form. This process is used to make extremely pure metal powder. This method is used to make highly conductive copper powder.
Atomization is a mechanical method of pulverizing the molten steel into pieces smaller than 150mm. According to the classification for crushing metal melt, the atomization process includes the second flow, centrifugal and ultrasonic atomizations, as well as vacuum atomization. Each of these atomization techniques has their own unique characteristics, and they have been used successfully in industrial production. Water-gas atomization is one of the most preferred industrial methods for making metal powder. It has simple equipment and processes, as well as low energy consumption.

Performance requirements of metal powder for 3D printing
1. Purity
Ceramic inclusions can adversely affect the performance of final products. They also have a high melting points, which makes it difficult to sinter. Powders must not contain ceramic inclusions. You must also control the nitrogen and oxygen levels. Powder preparation is done mainly using the atomization method. Powder with a large surface area is easy to oxidize. This index is required by customers for special applications such as aerospace. The superalloy and titanium alloy powder oxygen contents are 0.006%-0.018%, 0.007%-0.013%, and the powder oxygen content of stainless steel is 0.010%-0.025%.

2. Powder fluidity, loose density
The powder's fluidity directly influences the uniformity of powder spreading as well as the stability of powder feeding. Powder morphology, bulk density and particle size distribution are all factors that affect the fluidity. The fluidity of powder is determined by how regular and small the particles are. Fluidity increases with increasing relative density and increased particle density. The fluidity of powder is also reduced by the adsorption gas and water on its surface.

3. Powder particle size distribution
Different 3D printing equipments and forming processes have different requirements for powder size distribution. The most commonly used powder particle sizes in metal 3D printing are between 15-53mm (fine) and 53-105mm ("coarse"). There are several energy sources that can be used to select the metal powder size for 3D printing. Because of the fine focal spot and ease of melting fine powder, printers using laser energy are suitable to print 15-53mm-sized powder. A powder-laying printer that uses electron beam as an energy source has a slightly larger focal spot which makes it more suitable for melting powdery materials. It can be used for coarse powder sizes 53 to 105mm. As consumables for coaxial powder feeders, powders with particle sizes between 105 to 150mm are possible.

4. Powder morphology
The powder preparation method has a direct impact on the morphology. The shape of powder particles when metal gas or liquid is turned into powder is spherical. Powder particles that are made by aqueous electrolysis are dendritic. Generally speaking, higher sphericity means better fluidity for powder particles. This makes it easier to feed and lay powder during 3D printing.
