2. Ceramic materials
Ceramic materials have high hardness, high strength, low density, high temperature resistance, corrosion resistance and other excellent properties, and have a wide range of applications in the automotive, biological and other industries. 3D printed ceramic products are impervious to water, heat (up to 600 °C), recyclable, non-toxic, and can be used as an ideal cookware and candlestick, ceramic tile, vase, art and other furniture decoration materials. However, its strength is not high, and the hard and brittle characteristics make it difficult to form and process. Especially the complex ceramic parts need to be formed by grinding tools, and the mold processing cost is high and the development cycle is long, which is difficult to meet the demand of the product.
It has been reported that researchers at the University of the West of England have developed an improved 3D printed ceramic technology that can be directly printed, fired, glazed and decorated according to CAD data, eliminating the need for previous ceramic prototypes to overfire or test enamel. Question . In 2012, Belgium built a fast-made 3D printer using ceramic materials, which made it possible to produce fine and new forms of traditional ceramic technology.
3. Composite materials
In 2014, Arevo Laboratories in Silicon Valley, USA, introduced 3D printing technology for the manufacture of high-strength carbon composite end products, which printed a composite of carbon fiber reinforced nylon matrix. The nylon matrix is a lower polymer resin than PEEK.
Compared to conventional methods, 3D printing more precisely controls the orientation of carbon fibers, optimizing specific mechanical, electrical and thermal properties, rather than shaping them like conventional extrusion or injection molding methods. And since 3D printed composite parts can only be fabricated once, each layer can achieve any desired fiber orientation. The reinforcing phase of the composite material can be used not only as carbon fiber but also as glass fiber. The technology is targeted at parts for aerospace, defense and medical applications and is expected to develop lighter, stronger and longer-lasting components.
