builds.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"understanding-the-challenge\">Understanding the challenge<\/h2>\n\n\n<p>A common issue for users who print parts with MPBF is the buildup&nbsp;of&nbsp;thermal&nbsp;energy in certain areas of the part.&nbsp;The predominant&nbsp;area where this&nbsp;occurs&nbsp;is in&nbsp;overhangs, but&nbsp;it&nbsp;can also occur in parts with small layer scan&nbsp;areas.&nbsp;In both cases, there is a&nbsp;higher-than-normal&nbsp;energy density&nbsp;and a&nbsp;restriction in its dissipation.&nbsp;<\/p>\n\n\n\n<p>This&nbsp;causes visible defects like oxidation and&nbsp;discolouration, but&nbsp;can also&nbsp;cause&nbsp;physical ones like increased&nbsp;porosity&nbsp;and&nbsp;feature distortion.&nbsp;This is particularly the case with stainless&nbsp;steel, which has a&nbsp;relatively high&nbsp;melting point and a lower thermal conductivity.&nbsp;A great example&nbsp;of this&nbsp;is in the part below,&nbsp;where you can see the&nbsp;darker colours showing the oxidation&nbsp;and even some&nbsp;distortion on the corners of the rings.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\"

resulting&nbsp;laser powers&nbsp;on a per-voxel basis&nbsp;to not exceed this threshold.&nbsp;The image below shows&nbsp;how the laser power&nbsp;is scaled&nbsp;relative&nbsp;to the peak

The results showed substantial porosity in the builds that had a power reduction of up to 45% and 60% from the nominal value. However, no porosity was seen in the test builds for the 30% power reduction from the nominal value.
