Insufficient melting temperatures can result in incomplete fusion, while excessive laser power can cause keyholing. This leads to increased porosity and reduced part quality.<\/p>\n\n\n\n<p>Autodesk Fusion, equipped with the industry\u2019s most validated FEA process simulation solver, provides an ideal platform to address these challenges. This setup enables simulation-driven, upfront adjustments to laser power across the entire volume, ensuring consistent thermal performance and improved process reliability.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/sma-motor-v10b1.mp4\"><\/video><figcaption class=\"wp-element-caption\">Left: Build process temperature with constant laser power.

For example, local defects like corner hotspots and overhang surface quality are expensive or impossible to resolve. <\/p>\n\n\n\n<p>Emerging developments in <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/amug-2024-autodesk-fusion-amaize-collaboration\/\">physics-based AI surrogate modeling for process simulation<\/a> are moving those limitations quite a magnitude. However, this is also where an in situ, closed-loop approach to power control becomes highly complementary.

The stored data can be extracted at any time to generate detailed heatmaps and plots, offering enhanced visualization and actionable process insights.<\/p>\n\n\n\n<p>The resulting temperature control system effectively mitigates heat accumulation during layer exposure and stabilizes process temperatures across individual exposure vectors. Control plots generated from the system demonstrate its precision and reliability. The amount of detail and process insight is really remarkable.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1184\" height=\"958\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording1.jpg\" alt=\"\" class=\"wp-image-73644\" style=\"width:709px;height:auto\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording1.jpg 1184w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording1-300x243.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording1-1024x829.jpg 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording1-768x621.jpg 768w\" sizes=\"auto, (max-width: 1184px) 100vw, 1184px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1201\" height=\"976\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording2.jpg\" alt=\"\" class=\"wp-image-73649\" style=\"width:706px;height:auto\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording2.jpg 1201w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording2-300x244.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording2-1024x832.jpg 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/recording2-768x624.jpg 768w\" sizes=\"auto, (max-width: 1201px) 100vw, 1201px\" \/><\/figure>\n\n\n<h4 class=\"wp-block-heading\" id=\"bremer-institute-fur-angewandte-strahltechnik-bias\">Bremer Institute f\u00fcr Angewandte Strahltechnik (BIAS)<\/h4>\n\n\n<p>The BIAS in Bremen is one of Germany\u2019s leading laser research institutions. Unlike real-time process adjustment, BIAS researchers have explored a discretized approach, modulating laser power based on data from the previously recorded layer.<\/p>\n\n\n\n<p>In this method, the scan field is divided into thousands of small PID control elements, each independently adjusting the laser power for its specific region. This stepped approach effectively mitigates larger heat buildups, ensuring more consistent thermal management.<\/p>\n\n\n\n<p>Preliminary results from test prints indicate promising reductions in keyholes and porosity. Thus demonstrating the potential of this technique to enhance part quality.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"556\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/image-4-14.jpg\" alt=\"\" class=\"wp-image-73604\" style=\"width:710px;height:auto\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/image-4-14.jpg 576w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2024\/11\/image-4-14-300x290.jpg 300w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><figcaption class=\"wp-element-caption\">Project schematic: The power modulation of a certain field is determined by the layer below.<\/figcaption><\/figure>\n\n\n\n<p class=\"is-style-default\">Even more intriguing are the adjacent measurements conducted as part of this project.
