Tungsten 3D Printing for Medical Devices

What is Spherical Tungsten Powder?

Spherical tungsten powder is a kind of tungsten which has been specifically made to print 3D. This powder is meticulously made to make up the model of a spherical for this reason each powder particle being extremely homogeneous and small in proportion, enabling excellent printing results.

Exactly what is Tungsten Powder?

Tungsten powder is a type of powdered metallic tungsten, utilized like a raw material for the preparation of tungsten-processed substances including alloys, tungsten products and. It really is a gray-black metal using a metallic Lustre (body-centred cubic crystal). Melting point 3400. Boiling points 5555. The tungsten’s hardness is regarded as the hard from the metals. The most challenging tungsten rod is 200250 and is particularly the most difficult tungsten rod that has been spun right after the spinning hammer spins is 350400. It is actually soluble inside the mix acid of nitric acid and also hydrofluoric acid. It melts inside the mixture of sodium hydroxide and carbonate. A little soluble in nitric acid and sulfuric acid as well as aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two varieties A and B. At normal temperature and atmospheric pressure, type A is really a solid cylindrical structure that is certainly body-centered. Type B tungsten is able to be found in the presence of oxygen. It is actually stable to 630degC, then transforms to your tungsten at temperatures above 630degC. This treatment is unreversible.

Distinction between tungsten powder and spherical tungsten powder

Tungsten powder and tungsten spherical powder are both powder types of tungsten, nevertheless they have obvious differences in morphology, particle size and application.

Morphology


Tungsten powder is usually in granular form, while spherical tungsten powder is actually a spherical powder after special processing. This spherical shape allows tungsten powder to circulate and fill better in applications including 3D printing, providing more uniform printing results.

Particle Size


While tungsten powders have relatively large particle sizes, spherical tungsten powders have very fine particle sizes, usually from the nanometer range. This fine particle size allows tungsten powder to fit better in to the nozzle from the 3D printer, providing finer print details. Concurrently, the fine particles may also be able to fill the print bed, boosting the density and strength of the printed part.

Applications


Tungsten powder has a variety of applications in many fields, such as bulb manufacturing, electronics, and mechanical parts. Within these applications, tungsten powder is normally used as being a filler or alloying element. Spherical tungsten powder, around the other hand, is particularly suitable for areas like 3D printing, where it can perform creating more complex, high-precision parts and devices for its excellent flowability, filling effect and printability.

How do you prepare tungsten powder?

It is actually made by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The entire process of making the tungsten powder through hydrogen reduction can be separated into two phases one stage inside the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the second phase, at 700-900°C at which point tungsten dioxide will likely be reduced to the tungsten powder. The reduction reaction is generally done by the form of a tube or rotary furnace.

The efficiency of tungsten reduced powder (for example quality in addition to particle size, composition, size, etc.) mostly depends inside the means of reduction. Along the way of reducing tungsten in a oven tube, the main factors that affect the velocity of reduction are temperatures of reduction, amount of tungsten oxide in the burner vessel as well as the speed of movement the vessel is at, along with the rate of flow of hydrogen, and the amount of moisture in hydrogen. Since the temperatures of reduction, measurements of tungsten powder gets more coarse.

Production of tungsten powder together with the way of hydrogen reduction, additionally there is a tungsten oxide carbon reduction methods employed at the beginning The reduction temperature is higher than 1050 degrees Celsius . The purity of the tungsten oxide powder that is produced using this way is poor. Furthermore, with the aid of calcium, aluminum zinc, and various other reduction processes of tungsten oxide research is currently underway. For specific applications which need ultra-fine, ultrapure particle size of tungsten powder the introduction of the tungsten chloride hydrogen reduction process The tungsten powder particle dimension is lower than .05mm.

Industrial production can be achieved with the reduction of tungsten trioxide by hydrogen, or ammonium partungstate is cured with acid and after that tungsten trioxide can be created by maturation decomposition and after that reduced using hydrogen.

Hydrogen reduction using tungsten trioxide hydrogen reduction can be carried out by two steps The initial stage occurs when tungsten trioxide heating to 550-800 , using hydrogen reduction. The following stage of reduction transpires between 650 and 850 the tungsten powder is completed.

Also, it is actually possible to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then reduce it back to tungsten by hydrogen. The size and style and content in the tungsten powder are a vital quality indicator from the tungsten powder. The reduction process is conducted via a tube or even the rotary furnace.

Spherical tungsten powder has got the following advantages:

Spherical shape: The spherical shape allows the tungsten powder to improve fill paper bed through the printing process, providing a much more uniform print result. In comparison with traditional granular tungsten powder, spherical tungsten powder can better adjust to the 3D printing head and offer a smoother printing process.

Fine particle size: The fine particle size allows the tungsten powder to higher squeeze into the nozzle of your 3D printer, providing finer print details. The fine particles also fill the print bed better, improving the density and strength of your printed part.

Uniform particle distribution: Uniform particle distribution reduces clogging and defects during the printing process and improves print success. In traditional granular tungsten powders, the particle distribution is generally not uniform enough, which can lead to clogging or defects during the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this issue.

High purity: High-purity tungsten powder can offer better print performance and higher print quality. In some applications, it really is necessary to use high-purity material for printing to ensure the quality and gratification of parts.

Spherical Tungsten Powder Application Areas

Spherical tungsten powder has an array of applications, including although not restricted to these areas:

Aerospace: Spherical tungsten powder may be used to manufacture high-performance parts like aircraft structural components and engine parts. Within these applications, our prime strength, high density and purity characteristics of tungsten powder provides better printing performance and quality.

It needs to be noted that using spherical tungsten powder for 3D printing needs a certain amount of skill and experience. When you are a newcomer, it is recommended to apply with some more accessible 3D printing materials first. As well, using tungsten powder for 3D printing also requires special focus on safety, as tungsten is a high-density metal that can easily cause harm to a persons body. When you are performing so, be sure to keep to the relevant safety regulations and operating procedures.
