Thick Lacquering for PLA Models

thingiverse

Human: Seal the remaining grooves on the PLA models and build a thick coat to further protect it.\r\nThis method is suitable for models with simple shapes, but it's not suitable for models with complex shapes.\r\n\r\n##&#x1f6d1;Precautions\r\n- Ventilate the room during painting/drying/vaporing\r\n- Don't place the painted PLA models near the fire\r\n\r\n##&#x1f3a9;Requirements\r\n###&#x1f4aa;For Lacquering\r\n- 1 x <font color="DeepPink">Sanding sealer</font>\r\n - Choose a sanding sealer containing nitrocellulose as the base ingredient\r\n - Opt for a sanding sealer with a high ratio of ethyl acetate or butyl acetate as solvents\r\n - Use it as the top coat on the third layer\r\n - If you're concerned about patterns appearing on the painted surface, use the <font color="DeepPink">nail top coat</font>\r\n - For added safety, consider using paint that doesn't contain nitrocellulose as the top coat (However, smoothing with acetone vapor becomes impossible)\r\n - Mix with starch or ink respectively to create an under/middle coat for the second/third layer\r\n - When mixing, slowly rotate the container\r\n - Bubbles appear when using ice cream sticks\r\n- 1 x <font color="DeepPink">Starch</font> (corn or potato etc...)\r\n - Mix with the sanding sealer and use it for sealing the first layer\r\n - Use ice cream sticks when mixing\r\n - When starch is mixed with sealer, bubbles rarely appear\r\n- \* x <font color="DeepPink">Refill inks for permanent marker</font>\r\n - Choose your favorite ink color\r\n - Mix with the sanding sealer and use it for painting the second layer\r\n - When mixing, slowly rotate the container\r\n - Bubbles appear when using ice cream sticks\r\n- \* x <font color="DeepPink">Jam jars</font>\r\n - Use as a container for paint mixed with sanding sealer and starch/ink\r\n- \* x <font color="DeepPink">Ice cream sticks</font>\r\n - Use for mixing the paint of first layer\r\n - Use to substitute for brush\r\n- \* x <font color="DeepPink">Wet sandpapers</font> (400-1000 grit)\r\n - Use to sand each layers\r\n\r\n###&#x1F6BE;For Acetone Vaporing\r\n- 1 x <font color="DeepPink">Acetone</font>\r\n - Exposure to acetone vapor for 5 minutes will smooth the coated surface\r\n- 1 x <font color="DeepPink">Big jar</font>\r\n - I used a PET jar and a polypropylene lid, but it worked well without dissolving in acetone\r\n - Use upside down\r\n- 1 x <font color="DeepPink">Paper towel</font>\r\n - Drop acetone on a paper towel and vaporize it\r\n- 1 x <font color="DeepPink">Aluminum foil</font>\r\n - Stick to the inside of the big jar\r\n- 1 x <font color="DeepPink">3D models</font>\r\n - Use Sweetheart Flowers by MakerBot, Toothbrush Holder for Tray (V2), M18x2.5 Nut Spinner, or diep.io Tank Set Tier 3
