In addition to potential applications in the production of structural components and works of art, the material is particularly suitable for 3D printing of highly complex molds and cores for metal casting.[\/vc_column_text][vc_column_text]Friedberg near Augsburg, Germany, June 2021 &#8211; To develop the new high-performance ceramic material set Brightorb<sup>TM<\/sup> for 3D printing, AGC Ceramics Co., Ltd. has entered into a cooperation with voxeljet AG from Friedberg in Bavaria, Germany. Brightorb was developed on a <a href=\"https:\/\/www.voxeljet.com\/industrial-3d-printer\/prototyping\/vx1000\/\"><strong>VX1000<\/strong><\/a> with a build volume of 1000 x 600 x 500 mm. The 3D printing system works layer-based and bonds the ceramic particles with an inorganic binder. Targeted applications for the new, ceramic material set include high-performance cores for sand and investment casting, ceramic filters, structural components, as well as art and product design.[\/vc_column_text][vc_column_text]The ceramics material with its brand name Brightorb is composed of spherical sand with the main components Aluminum Oxide (Al2O3) 80%, Zirconium Oxide (ZrO2) 10%, Silicon Oxide (SiO2) 9%, the minerals Corundum, Baddeleyite and kinds of cement. During 3D printing, Brightorb is applied to the build platform with average grain sizes of 50 \u00b5m and layer thicknesses of 100 \u00b5m and selectively bonded with an inorganic binder. The inorganic binder is characterized by its high environmental compatibility as only water vapor is produced during molding. This greatly improves environmental and working conditions in foundries. To subsequently prepare the printed ceramic for the final application, the printed components get impregnated by a silica-based liquid and have to be fired in a sintering furnace for their final strength. Most of the unprinted powder can be reprocessed, recycled and fed back into the printing process.[\/vc_column_text][vc_column_text]&#8221;We have been noticing a growing demand for increasingly complex component geometries among our customers for a long time,&#8221; explains Dr. Ingo Ederer, CEO at voxeljet. &#8220;The great advantage of the geometric freedom of 3D printing is, that geometric adjustments can significantly optimize the efficiency and effectiveness of, for example, engines or turbine wheels. It is rare that such complex components can still be produced using conventional molding processes. Together with AGCC, we have been able to optimize a VX1000 for ceramic powder in close cooperation, so that it is ideally suited for the challenging demands of metal casting. Both in terms of strength and surface quality&#8221;, says Dr. Ederer.[\/vc_column_text][vc_column_text]The <strong><a href=\"https:\/\/www.voxeljet.com\/3d-printing-solution\/technical-ceramics\/\">3D-printed ceramics<\/a><\/strong> are used, for example, as cores for the investment casting process in order to reproduce complex and filigree cavities within castings. In this process, the filigree cores are combined with conventional wax patterns. These are coated with a ceramic slurry and burned out before casting. What remains is a hollow ceramic mold in which the printed core is still inserted. Molten metal is then poured into the mold. After cooling, both the mold and the core are removed.[\/vc_column_text][vc_column_text uncode_shortcode_id=&#8221;167260&#8243;]This process makes it possible, for example, to integrate internal cooling channels in turbine blades, thus increasing turbine efficiency and reducing downtimes to a minimum. Mr. Ushimaru, Additive Manufacturing Director from AGCC is also satisfied: &#8220;Brightorb is a high-performance ceramic that is extremely well suited for metal casting due to its high-chemical stability, heat resistance, thermal conductivity and low thermal expansion. We were able to optimize the material set in such a way that the shrinkage factor of the printed components during the downstream sintering process at 1,400\u00b0C is less than 1%. This means that the components are also suitable for filigree core designs. Thanks to the high-fire resistance, it is possible to cast alloys with melting points beyond 1,600\u00b0C. Overall, ceramics will continue to gain importance as a material in the future, and the same applies to <strong><a href=\"https:\/\/www.voxeljet.com\/additive-manufacturing\/3d-printing-processes\/binder-jetting-technology\/\">3D printing as a manufacturing technology<\/a><\/strong>. We are pleased to have embarked on this path together with voxeljet and look forward to further close cooperation.&#8221;[\/vc_column_text][\/vc_column][\/vc_row][vc_row unlock_row_content=&#8221;yes&#8221; row_height_percent=&#8221;50&#8243; override_padding=&#8221;yes&#8221; h_padding=&#8221;0&#8243; top_padding=&#8221;0&#8243; bottom_padding=&#8221;3&#8243; overlay_alpha=&#8221;50&#8243; equal_height=&#8221;yes&#8221; gutter_size=&#8221;0&#8243; column_width_percent=&#8221;100&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243;][vc_column column_width_percent=&#8221;100&#8243; position_vertical=&#8221;middle&#8221; gutter_size=&#8221;3&#8243; override_padding=&#8221;yes&#8221; column_padding=&#8221;4&#8243; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; shift_y_down=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; mobile_width=&#8221;0&#8243; width=&#8221;1\/2&#8243; mobile_height=&#8221;300&#8243;][vc_row_inner row_inner_height_percent=&#8221;50&#8243; overlay_alpha=&#8221;50&#8243; gutter_size=&#8221;3&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; css=&#8221;.vc_custom_1589292226437{padding-right: 0px !important;}&#8221;][vc_column_inner column_width_use_pixel=&#8221;yes&#8221; position_horizontal=&#8221;right&#8221; position_vertical=&#8221;middle&#8221; gutter_size=&#8221;3&#8243; override_padding=&#8221;yes&#8221; column_padding=&#8221;5&#8243; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; shift_y_down=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; mobile_width=&#8221;0&#8243; width=&#8221;1\/1&#8243; column_width_pixel=&#8221;455&#8243; css=&#8221;.vc_custom_1589292348537{padding-right: 0px !important;}&#8221;][vc_column_text uncode_shortcode_id=&#8221;340985&#8243;]Brightorb was qualified in voxeljet&#8217;s Material Certification Lab in Friedberg, Bavaria, Germany.
