WHAT IS TOPOLOGICAL OPTIMIZATION?<\/span><\/h2>\r\n

Topological optimization<\/b> allows us to<\/span> automatically<\/span> lighten<\/b> parts using the finite element method. Topological optimization allows us to automatically lighten parts using the finite element method. The topology study starts from basic data of a part (design volume, loads, fixtures, manufacturing controls and study objectives) and executes <\/span>an iterative algorithm<\/b> that provides a<\/span> structurally optimal par<\/b>t.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Finite element-based topological optimization is a process of finding the<\/span> optimal distribution of material <\/b>and<\/span> voids <\/b>in a given design space, according to loading and boundary conditions, so that the resulting structure meets<\/span> prescribed performance objectives<\/b>.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Topological optimization of parts where no manufacturing constraints are applied will result in products with<\/span> an organic appearance. <\/b>This is because the material will choose <\/span>the shortest path <\/b>from load to constraint<\/b>, resulting in the most mathematically efficient shape.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

This methodology was developed as an advanced structural design technique to generate<\/span> innovative<\/b>, lightweight<\/span>, high<\/b>–performance <\/span>configurations<\/b>.that are difficult to obtain using conventional ideas. As a result, it has become a <\/span>leading<\/b> structural design <\/span>technique<\/b> for <\/span>high-performance<\/b>, <\/span>lightweight,<\/b> multifunctional structures, <\/span>and <\/b>has been widely used <\/span>in aerospace, <\/b>automotive, <\/span>architecture, <\/b>etc.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

TOPOLOGICAL OPTIMIZATION AND ADDITIVE MANUFACTURING<\/span><\/h2>\r\n

As we already know<\/span>, additive manufacturing <\/b>is an advanced manufacturing technique that builds<\/span> structures according to a design <\/b>by joining material layer by layer. This achieves alternative patterns for complex components.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

The<\/span> combination<\/b> of<\/span> topological optimization <\/b>and<\/span> additive manufacturing <\/b>makes it possible to take full advantage of their benefits and strengths, with broad<\/span> prospects for application<\/b> in modern manufacturing.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Although topological optimization as a design tool has been available for several decades, the constraints imposed by traditional manufacturing techniques have greatly limited its usefulness. This is now changing with the continued <\/span>development and increasing use of FA in the industry. <\/b>With FA it is possible to print almost any geometry. Unlike size and shape optimization, <\/span>structures optimized by topological optimization can achieve any shape within the design space<\/b>.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/mizaradditive.com\/wp-content\/uploads\/2021\/11\/30-11-21-Optimizacion-topologica-900-x-600-px.jpg” alt=”Topological optimization and additive manufacturing” title_text=”Topologically optimized part” _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Thus, thanks to additive manufacturing the possibilities are almost endless; even more so since additive manufacturing places no restrictions on the shape of the part, the only restriction with additive manufacturing being the minimum wall thickness.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

TOPOLOGICAL OPTIMIZATION AND PRODUCT DESIGN<\/span><\/h2>\r\n

Topological<\/span> optimization <\/b>is<\/span> the<\/b> most<\/span> complicated<\/b> task in<\/span> structural design optimization problems <\/b>because the general layout of the structure is not known; however, its application at the conceptual design stage has been shown<\/span> to reduce cost and development time<\/b>.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Although topological optimization has a wide range of applications in engineering product design, it is currently used primarily<\/span> in the design phase<\/b> to optimize part size and shape.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

Topological optimization allows designers<\/span> to optimize a component or mechanical part<\/b>,usually by reducing material. Topological optimization allows designers to optimize a component or mechanical part, usually by reducing material. It is actually a form of generative design, which refers to the combination of three different disciplines: design, simulation and optimization.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

APPLICATIONS OF TOPOLOGICAL OPTIMIZATION AND ADDITIVE MANUFACTURING<\/span><\/h2>\r\n

Without the need for additional tooling, moulds or complicated procedures<\/span>, additive manufacturing<\/b> is<\/span> suitable<\/b> for the fabrication of<\/span> complex structures<\/b> which, in addition to<\/span> saving<\/b> production <\/b>costs<\/span>,<\/b> shortens<\/span> the manufacturing cycle <\/b>(especially in rapid prototyping and small-batch production).<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

In addition, additive manufacturing facilitates the<\/span> design of integral structures<\/b> that reduce the number of parts and assembly processes. Over the past few decades, various additive manufacturing techniques have emerged, such as Selective Laser Sintering <\/span>(SLS<\/b>)<\/a>, Selective Laser Melting (SLM<\/strong>)<\/span> and Fused Deposition Modelling<\/span>(FDM),<\/b> among others.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

The <\/span>materials<\/b> used include metal, polymer, composite, biomaterial, etc. FA fabricated parts range from micro-nano components to large structures. With its powerful <\/span>customized manufacturing capabilities<\/b>, AF has broken away from conventional manufacturing techniques and has played an important role in the advanced manufacturing industry, which has <\/span>wide application <\/b>prospects in <\/span>aerospace<\/b>, <\/span>mechatronics<\/b>, <\/span>medicine<\/b> and<\/span> civil engineering.<\/b><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

AF<\/span> enables<\/b> engineers to work without the limitations of conventional manufacturing techniques and to pay attention to<\/span> the design of lightweight<\/b>, high-performance<\/span> structures<\/b>. In turn, <\/span>topological optimization<\/b> is an effective approach for additive manufacturing products that require<\/span> lightweight and innovative configurations<\/b>.<\/span><\/p>\r\n

The integration of topological optimization and AM is an important way to achieve<\/span> correspondence between structural <\/b>design and manufacturing.<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

CONCLUSION<\/span><\/h2>\r\n

Additive manufacturing has made it possible<\/span> for the organic shapes <\/b>characteristic of topological optimization to be<\/span> manufacturable<\/b> and become a symbol of <\/span>innovation<\/b>. Its breakthrough in the field of industrial design is remarkable: it brings a great advantage over traditional technologies thanks to <\/span>the freedom of design <\/b>(resulting from the possibility of printing any geometric shape).<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.14.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

The generative design allows the creation of new geometric shapes through algorithms and <\/span>the topological optimization software<\/b> allows <\/span>materials<\/b> to be placed<\/span> only where necessary<\/b>, thus reducing the weight and cost of the parts.<\/span><\/p>\r\n
