Combined First Layer + Adhesion Test

prusaprinters

<h3>The Ultimate First Layer and Adhesion Calibration</h3><p><strong>I designed this model to test several calibration and adhesion aspects like for example:</strong><br><br><strong>Nozzle Offset</strong><br><strong>Adhesion</strong><br><strong>Roundness</strong><br><strong>Small-feature performance</strong><br><br>Also it <strong>gives you an indication</strong> for <strong>retraction- and extrusion-multiplier</strong> settings.</p><p>Designed for <strong>Original Prusa Mk3 </strong>but scaling to any other build plate (e.g. <strong>Original Prusa Mini</strong>) is of course possible.</p><p><strong>I hope this model helps you as much as it helped me on the way to fast and successful, trouble free printing.</strong><br><br>Please see below for more Details.<br><br><strong>Happy Printing!</strong></p><p>&nbsp;</p><h3><strong>Features:</strong></h3><p><strong>1.) Print-bed orientation markers for easy allocation:</strong></p><figure class="image image-style-align-center image_resized" style="width:79.21%;"><img src="https://media.prusaprinters.org/media/prints/108863/rich_content/e6d5475a-c0b5-4e06-be8e-3a32f1722772/foto-281221-12-07-37.jpg#%7B%22uuid%22%3A%223cd9ceb5-45ad-45f4-9e78-74482e72ebfe%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><figure class="image image-style-align-center image_resized" style="width:79.08%;"><img src="https://media.prusaprinters.org/media/prints/108863/rich_content/820d187f-a64d-4fd0-bb59-799a97b47e81/foto-281221-12-07-42.jpg#%7B%22uuid%22%3A%229dff670b-3e4f-4621-ac28-dfb24c4fc5b8%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p>&nbsp;</p><p><strong>2.) Most common shapes you will find in regular models to help with evaluation of important parameters.</strong></p><p><strong>Circle: </strong>Somethimes when printing circular patterns, they keep coming out as an oval shape. This test print will help you to reveal that issue and speed up trouble-shooting.</p><figure class="image image-style-align-center image_resized" style="width:53.74%;"><img src="https://media.prusaprinters.org/media/prints/108863/rich_content/9932aab0-5651-4110-a42b-9cb999f21156/30-12-_2021_15-19-29.jpg#%7B%22uuid%22%3A%22fac076d9-7b5b-4200-a1fe-f2502161bd8f%22%2C%22w%22%3A370%2C%22h%22%3A360%7D"></figure><p>&nbsp;</p><p><strong>Triangle:</strong> Cornes with an angle below 90° are sometimes hard to print at the tip of the corner.<br>While a rectangular shape won't show this issue (cause all cornes are 90°), the triangle with corners at 60° will.</p><figure class="image image-style-align-center image_resized" style="width:60.56%;"><img src="https://media.prusaprinters.org/media/prints/108863/rich_content/432de3e3-ab1e-4a86-9992-76c2d440b014/30-12-_2021_15-24-18.jpg#%7B%22uuid%22%3A%22a9fd779c-72f8-4155-8db2-84c9bf5d7aab%22%2C%22w%22%3A458%2C%22h%22%3A374%7D"></figure><p>&nbsp;</p><p><strong>A finely jagged pattern: </strong>This part of the test print will most likely trigger some retractions as the print head needs to move arount to fill the small gaps in the corners.&nbsp;<br>Obersving the results will help you to judge the flow (extrusion multiplier) and retraction settings.<br>(Plus: In case you struggle with local or evenly distributed bed adhesion-issues, the small details in the middle of the print bed will show them too.)</p><p>&nbsp;</p><figure class="image image-style-align-center image_resized" style="width:61.28%;"><img src="https://media.prusaprinters.org/media/prints/108863/rich_content/40a48492-588f-4dc0-927b-3e3a2e7f115c/foto-281221-12-07-49.jpg#%7B%22uuid%22%3A%22fecbbbbe-4c59-4a3c-acef-260a405b96bb%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p><br><strong>3.)
