3D printing material as a new technology industry, has developed rapidly in recent years and has become the focus of the world to promote the development of the industry.

At present, the total amount of 3D printing materials more than 200 kinds, every period of time there will be material born, however, for the development of 3D printing, these materials are far from enough.

3d printer printing products

In recent years, plastics, ceramics, metals, LayWood and wax materials have been used as 3D printing materials.

And 3D printing material according to the 3D printing forming technology is different, the type is not the same, the following diagram is different molding technology using 3D printing material.

SLA/DLP is the light curing machine models, we often say that the general used for resin materials, such models often used to cure materials by irradiation method is focused, so the general resin material for liquid state.

Other forming technologies, such as selective laser sintering (SLS), direct metal laser sintering (DMLS) and electron beam melting (SHS), are usually made of metal.

In the view of alunar 3D printing technology really has the advantage of printing materials, 3D printing materials is an important material foundation for the development of 3D printing technology, to a certain extent, the development of materials determines whether 3D printing more widely used.

3D printing can well imitate the mechanical or thermal properties of plastic and metal materials, but this is also a major technical reason for restricting the development of 3D printing.

1. 3D Printed Polymer Material




3D Printed Polymer Material

The most widely used is polymer acrylonitrile. Although 3D materials begin to shift to metal, polymers will become market dominant materials for a period of time.

2. Engineering Plastics




Engineering Plastics

Engineering plastics, plastic refers to is used as shell material or industrial parts industry, has the advantages of high strength, impact resistance, heat resistance, high hardness and anti aging properties, the normal deformation temperature can exceed 90 DEG C, for machining, painting and plating.

Engineering plastics are the most widely used 3D printing materials, such as acrylonitrile butadiene styrene copolymer (ABS), polyamide (PA), polycarbonate (PC), poly (PPSF) and PEEK.

3. Biomaterials




Biomaterials

Some of the future 3D printing biomaterials include hot chrome, polylactic acid, nylon 11, flexible polylactic acid or soft poly lactic acid, bio rubber, straw based and bamboo based biomaterials, and laybrick.

The color changes of the hot chromium polylactic acid filament under temperature change; flexible polylactic acid or soft polylactic acid and nylon 11 have high flexibility; straw based and bamboo based biomaterials have low cost advantages.

4. Metal Materials




Metal Materials

Metal materials are more used in the dental industry, mainly titanium, aluminum, chromium, cobalt and so on. According to the income, the market share is below 30%. Aviation will be the main field for driving the growth of metal materials usage.

5. Polymer Gel




Polymer Gel Good with intelligent polymer gel, sodium alginate, cellulose, vegetable gum, peptone, polyacrylic acid gel polymer materials for 3D printing, polymerization at certain temperature and initiator, cross-linking of polymer gel, forming a network of special products.

If the ionic strength, temperature, electric field and chemical changes, the volume of the gel will change accordingly, used for shape memory materials. The volume change of gel swelling or contraction is used for sensing materials, and the controllability of gel mesh can be used for intelligent drug delivery materials.

6. Ceramic Materials




Ceramic Materials

Ceramic materials with high strength, high hardness, high temperature resistance, low density, good chemical stability, corrosion resistance and other excellent characteristics, in aviation, aerospace, automotive, biological and other industries have a wide range of applications.

However, due to the hard and brittle characteristics of ceramic materials, it is difficult to process. Especially complicated ceramic parts need to be formed by moulds. Mold processing costs high, long development cycle, it is difficult to meet the needs of constantly updated products.

7. Other 3D Printing Materials




In addition to the above 3D printing materials, there are also color gypsum materials, artificial bone meal, cell biological raw materials and sugar and other materials.

Color gypsum material is a full color 3D printing material, which is based on plaster and is fragile, firm and clear color.

The forming principle of layer printed on the powder medium based on 3D in the finished print after the treatment, the surface may appear fine particle effects, much like the appearance of the rock on the curved surface may appear slight ring texture, therefore, more and more used in fields such as cartoon dolls.

3D printing technology, combined with medicine and tissue engineering, can produce drugs, artificial organs and so on for the treatment of diseases. Canada is currently developing "bone printers", using inkjet printer technology to convert artificial bone powder into sophisticated bone tissue. The printer sprays the acid film on the bone meal to make the film harder.
