To make PLA plastic at home using corn or potato starch, you will need the following ingredients:
<h3>Ingredients:</h3><ul><li><strong>Starch Source</strong>: Corn or Potato Starch</li><li><strong>Catalyst</strong>: Sulfuric Acid</li><li><strong>Solvent</strong>: Ethanol</li><li><strong>Plasticizer</strong>: Glycerol
### Equipment:</li><li>Mixing Bowl</li><li>Stove</li><li>Double Boiler</li><li>Molds</li><li>Stirring Rod</li><li>Measuring Spoons
<h3>Steps to Make PLA Plastic:</h3>
1. <strong>Prepare the Starch</strong>:
<ul><li>In a mixing bowl, mix the corn or potato starch with a small amount of ethanol to form a slurry.</li></ul>
2. <strong>Add the Catalyst</strong>:
<ul><li>Slowly add sulfuric acid to the starch mixture while stirring continuously. Be cautious as sulfuric acid is corrosive.</li></ul>
3. <strong>Cook the Mixture</strong>:
<ul><li>Place the mixing bowl in a double boiler on the stove. Heat the mixture while stirring until it thickens.</li></ul>
4. <strong>Add Plasticizer</strong>:
<ul><li>Once the mixture thickens, add glycerol as a plasticizer to improve the flexibility and durability of the PLA.</li></ul>
5. <strong>Mold the Plastic</strong>:
<ul><li>Pour the mixture into molds before it cools and solidifies. Allow it to cool and harden.</li></ul>
6. <strong>Finalize the PLA</strong>:
<ul><li>Once the plastic has hardened in the mold, carefully remove it and let it dry completely. Your homemade PLA plastic is now ready for use.</li></ul>
Please note that working with chemicals and heat sources can be dangerous. Always wear appropriate protective gear and work in a well-ventilated area when conducting experiments of this nature.</li></ul></span></div></div></div></div><div id=chatlog__message-container-1219981590784901120 class=chatlog__message-container data-message-id=1219981590784901120><div class=chatlog__message><div class=chatlog__message-aside><div class=chatlog__short-timestamp title="Wednesday, March 20, 2024 1:11 PM">1:11 PM</div></div><div class=chatlog__message-primary><div class="chatlog__content chatlog__markdown"><span class=chatlog__markdown-preserve>Let us know how it goes, and feel free to add this to the wiki</span></div></div></div></div></div>
