The Thirteenth Hour Podcast #579: Making a Mold and Resin Casting the New Aurora Minifigure for Dare

<p>In this week&#39;s episode, I&#39;m making the silicone mold for the new Aurora minifigure and then testing to see if it worked by doing the first few resin casts.</p><p>Here she is, in a paper cup, about to get siliconed.</p><p> I added these sticks to parts I was concerned would not fill.  These sticks will serve as airvents, allowing the air to escape and the resin to replace the air.</p><p> I glued the sprues that serve as the vents at the points on the figure that are protruding the most.</p><p> To the left you can see a batch of Smooth On Mold Star 30, the epoxy silicone I&#39;m using.</p><p>There is no way to avoid all the bubbles, but when I pout the silicone over Aurora, I will let it pour from a high height so the air has some time to escape.</p><p> Here is the mold after it has cured.</p><p>Flipped over, the mold will have Aurora&#39;s feet in the air - those serve as the pour spouts of the liquid resin, which has a cure time of about 60-90 seconds.  You can see the foot on the right has just cured (solid white) and the one of the left is in the process of curing.</p><p>Two different resins - on the left, Smooth Cast 57D as semi rigid (flexible) resin that cures translucent and on the right, Smooth Cast 300, a harder, more brittle resin that cures solid and shows details better.</p><p>Pretty happy with how the fine details came out! </p><p>All pictures are here: <a href="https://13thhr.wordpress.com/2026/09/14/the-thirteenth-hour-podcast-579-making-a-mold-and-resin-casting-the-new-aurora-minifigure-for-dare/" target="_blank" rel="noopener noreferer">https://13thhr.wordpress.com/2026/09/14/the-thirteenth-hour-podcast-579-making-a-mold-and-resin-casting-the-new-aurora-minifigure-for-dare/</a></p><p>More next week!</p><p>∞∞∞∞∞∞∞∞</p><p><br></p><p><em>Once Upon a Dream</em>, the second <em>Thirteenth Hour</em> soundtrack, is now out in digital form!  </p><p> <br>It is out on most major streaming services such as <a href="https://wordpress.us10.list-manage.com/track/click?u=3ca280fd186ff5792e73845e5&id=44c870efa6&e=0ac5f1a816" target="_blank" rel="noreferrer noopener">Bandcamp</a>, <a href="https://wordpress.us10.list-manage.com/track/click?u=3ca280fd186ff5792e73845e5&id=7fc1504305&e=0ac5f1a816" target="_blank" rel="noreferrer noopener">Spotify</a>, and <a href="https://wordpress.us10.list-manage.com/track/click?u=3ca280fd186ff5792e73845e5&id=830234d55c&e=0ac5f1a816" target="_blank" rel="noreferrer noopener">YouTube Music</a>.  (If you have no pre
