PBF-LB apparatus and process for the additive manufacturing of single- and multi-material objects<\/h1>\n

[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column width=”2\/3″][vc_empty_space][vc_column_text]The proposed technology aims to use PBF-LB metal powder bed additive manufacturing technology to create objects composed of multiple materials by exploiting the growth direction of the components, layer by layer, while overcoming the technical problems essentially related to: i) contamination of metal powders from different materials, ii) poor geometric resolution, and iii) post-operations that are actually applicable to the objects produced.[\/vc_column_text][vc_empty_space][vc_single_image image=”4796″ img_size=”full” qode_css_animation=””][vc_empty_space][vc_column_text]<\/p>\n

How does it work?<\/span><\/h3>\n

[\/vc_column_text][vc_empty_space][vc_column_text]The technical core of the technology is the possibility of breaking free from the different types of powder deposition systems on the construction platform and focusing on the possibility of spatial orientation of the latter, exploiting the simple direction of growth. This approach allows the possibility of combining PBF-LB technology with traditional production methods, thus combining parts produced with subtractive methods with parts produced with additive methods. <\/p>\n

The technology therefore focuses on the creation of a construction platform that can be rotated in space around three main directions, in order to make the surfaces of the components on which the transition between two different materials is to be made flat and perpendicular to the direction of growth.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n

Applications<\/span><\/h3>\n

[\/vc_column_text][vc_column_text]The proposed solution can be integrated into existing PBF-LB systems, as a possible upgrade to be sold to the machine owner, or directly integrated into newly manufactured and\/or designed systems.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n
