As a rule, ceramics are first formed as green bodies from raw mass, before this \u201cgreen body\u201d is then treated and fired in a special way (so-called sintering) to harden it and bring it into its final form.<\/p><p>Depending on the industry, this can be simple tableware, decoration or sanitary ware, but also technical ceramics such as prostheses, or various technical components. A ceramic workpiece is usually fired in a kiln after initial mechanical processing. It is exposed to temperatures of between 900 \u00b0C and 1400 \u00b0C.<\/p><p>This is done by heating in a defined time interval at a steadily increasing temperature, but also at precisely defined isothermal intervals to control chemical reactions during firing of the ceramic and to control the degassing of water vapor, carbon dioxide and other admixtures. After the initial firing, a glaze is often added to the ceramic and then the piece is fired again to fully cure it.<\/p><p>The entire process takes several hours and is therefore not inconsiderably time-consuming. In addition, it cannot be guaranteed that the workpiece will come out of the kiln undamaged after firing; various errors (lack of material, incorrect firing process, etc.) can occur, which can lead to breakage or cracks in the ceramic.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4dbc798 elementor-widget elementor-widget-spacer\" data-id=\"4dbc798\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d6d557b elementor-widget elementor-widget-spacer\" data-id=\"d6d557b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-93f86bf elementor-widget elementor-widget-spacer\" data-id=\"93f86bf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-104c7f5 elementor-widget elementor-widget-text-editor\" data-id=\"104c7f5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>A more modern and simpler solution for firing a wide variety of ceramic components is additive manufacturing. In the case of ceramics, this is often referred to as 3D printing. This is a manufacturing process in which material is applied layer by layer to create three-dimensional objects.<\/p><p>The build-up is usually computer-aided design (CAD) and one or more liquid or solid materials are used as the starting material according to specified dimensions and shapes. During the build-up by means of printing process, chemical <a href=\"https:\/\/www.linseis.com\/en\/wiki\/phase-transition-of-a-substance-melting\/\"><strong>curing or melting processes<\/strong><\/a> take place, often controlled by means of temperature or laser. It is even possible to use a 3D scanner for a model.<\/p><p>The advantage of the method over conventional firing processes is clear: By applying the ceramics in layers, it is possible to produce filigree and complex structures for which the risk of breakage during the firing process would be particularly high. In addition, enormous time savings are achieved, as an additively sintered or 3D-printed workpiece can be manufactured much more quickly due to the fact that the firing process in the furnace is not necessary.<\/p><p>Compared to all material-removing processes such as cutting, turning and drilling, 3D printing has the advantage of eliminating the additional machining step after the original mold. In most cases, the process is also more energy efficient, especially if the material only needs to be built up once in the required size and mass. It is also advantageous that different materials can be processed in a single machine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-df9d090 elementor-widget elementor-widget-spacer\" data-id=\"df9d090\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5c4ab62 elementor-widget elementor-widget-spacer\" data-id=\"5c4ab62\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-967fcf7 elementor-widget elementor-widget-spacer\" data-id=\"967fcf7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7165763 e-con-full e-flex e-con e-child\" data-id=\"7165763\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-9cd3e6a e-con-full e-flex e-con e-child\" data-id=\"9cd3e6a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d6967c7 elementor-widget elementor-widget-text-editor\" data-id=\"d6967c7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Originally, the process of 3D printing was first applied and developed in the <a href=\"https:\/\/www.linseis.com\/en\/applications\/polymers\/\"><strong>polymer industry<\/strong><\/a>, as plastics are easy to melt and handle and do not require sintering or curing.

Materials in general: metal, ceramic, plastic.<\/p><p>The main field of application of additive manufacturing technology is still research and, above all, product development or prototype construction in industry. It is ideally suited for the production of models, prototypes, tools or specific products, as no special tools are required and the conversion from drawing to model can be realized very quickly.<\/p><p>Other areas of application are primarily <a href=\"https:\/\/www.linseis.com\/en\/applications\/cosmetics-pharmaceuticals-food\/\"><strong>medical technology<\/strong><\/a>, where specially adapted prostheses and implants (especially also in dentistry) have to be made, often individually customized. But more unusual fields of application, such as sculpture and art, also use additive manufacturing to produce sculptures. Meanwhile, 3D printers can also be used in private use, as the processes and printers have now reached production maturity and are available to the public at relatively low cost. In the household, plastic products in particular, such as toys, spare parts or small holders, can be produced easily and without much prior knowledge.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b869321 elementor-widget elementor-widget-heading\" data-id=\"b869321\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"> For ceramics, the following methods are used for 3D printing:<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-03bc60f elementor-widget elementor-widget-text-editor\" data-id=\"03bc60f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul>\n<li>Powder bed fusion processes, such as selective laser sintering (SLS).

A thin layer of the powder is placed on a tray using a nozzle. A laser then begins to sinter the powder locally, creating the first layer. A variation of this is 3D inkjet printing. Here, a binder is printed onto a layer of powder (plaster or resin) in the cross-section of the part using an inkjet-like process.
