<p>I have a printer with a 0.1 mm typical layer thickness. Of course I can choose some different sizes in Cura or other slicing software, but most prints on this machine will be .1mm. In my (admittedly limited) experience thus far, the 0.1 mm seems typical for other printers, too.</p>

<p>I want to get a sense of just how thick this is. I know about the paper trick for leveling the print bed, but my understanding is the first layer pushes into the bed a little, meaning it's less than 0.1 mm and so paper isn't a good example for the typical layer. </p>

<p>Is there a similar item with close to 0.1 mm thickness I can use to visualize this?</p>

However, <strong>an average sheet of 80gsm paper, the most commonly used weight, measures approximately 0.1mm in thickness</strong>, which means that <em>10 sheets would measure 1mm</em>. By comparison, <em>10 sheets of 120gsm paper would be 1.5mm thick</em>, assuming the paper composition was the same.</p>\n</blockquote>\n\n<p>So, given that:</p>\n\n<ul>\n<li>80&nbsp;gsm => 0.1&nbsp;mm</li>\n<li>120&nbsp;gsm => 0.15&nbsp;mm</li>\n</ul>\n\n<p>Then </p>\n\n<ul>\n<li>40&nbsp;gsm => 0.05&nbsp;mm</li>\n<li>60&nbsp;gsm => 0.075&nbsp;mm</li>\n</ul>\n\n<p>From <a href="http://www.officexpress.co.uk/paper-guide/" rel="nofollow noreferrer">A Guide to Paper Types and Sizes</a></p>\n\n<pre><code>Paper Weight Descriptions\n\nWeight        Feels Similar to:\n\n35-55 gsm     Most newspapers\n90 gsm        Mid-market magazine inner pages\n130-250 gsm   A good quality promotional poster\n180-250 gsm   Mid-market magazine cover\n350 gsm       Most reasonable quality business cards\n</code></pre>\n\n<p>So, it would appear that you could use a newspaper sheet (or two) to test for layers of less than 0.1&nbsp;mm.  Obviously this would depend upon where in the world you are, and the (physical) quality of your newspapers. Here in the UK, or rather Europe, the <em>exported version</em> of the Guardian used to be printed on some extremely lightweight paper (almost transparent tissue thin), in order to keep the costs of transport down to a minimum. So a folded sheet of that would certainly be in the range of 0.75 - 0.99&nbsp;mm (which seems to be the range that you are looking for). However, given that the printed media (as opposed to the online version) is currently in decline, I am not entirely sure if it is still available.</p>\n\n<p>Or, how about grease proof paper? From the <a href="https://en.wikipedia.org/wiki/Greaseproof_paper" rel="nofollow noreferrer">Wikipedia entry</a>:</p>\n\n<blockquote>\n  <p>Basis weights are usually 30–50 g/m²</p>\n</blockquote>\n\n<p>Although, this paper has been processed (<a href="https://en.wikipedia.org/wiki/Supercalendered" rel="nofollow noreferrer">supercalandered</a>) and treated with starch, which will increase the density, so the thickness will not correlate to the table above (i.e. it will be thinner).</p>\n\n<p>Giftwrap paper (not the really thick stuff) could be another option.</p>\n\n<p>After having doing some long winded googling, I guess that the best bet would be to get hold of a micrometer and measure whatever paper yourself, as the specifications of paper are generally given in <code>gsm</code> and not <code>mm</code> (which is a bit annoying), and so it is somewhat difficult to provide you with a definitive answer (without physically measuring it).</p>\n'}, {'answer_id': 6617, 'author': 'Sean Houlihane', 'author_id': 4927, 'author_profile': 'https://3dprinting.stackexchange.com/users/4927', 'pm_score': 2, 'selected': False, 'text': '<p>Maybe a better way to visualise 0.1mm is to explain that it only becomes really visible on a shallow slope.
