Ultra adhesive build plate coating recipe

thingiverse

Here's a recipe for an ultra adhesive build plate coating. The coating provides perfect adhesion for ABS, PLA, and PETG. First layer heights of 0.1mm are possible for ABS, PLA, and PETG. The printed objects can be removed when the build plate has cooled down to about 25°C. The coating takes only 15 minutes to prepare, with 10 minutes idle time. To make it, you'll need a bowl, a spoon, one sheet of gelatin (1.5 gramm), and about 50 mm of water (mildly warm, hand friendly - not warm or hot). Here's how to do it: Put the sheet of gelatin in the water and let it sit there for 10 minutes. It won't dissolve right away. Then, squeeze that sheet of gelatin with the spoon here and there, just a little (5 seconds). Now coat the build plate with a small amount of that jelly water, creating a thin film. You can optionally heat up the build plate to dry it faster, or just wait until it's dry. Once it's ready, you're good to print. Print with a heated bed at typical temperatures for PLA (65°C), PETG (90°C), and ABS (110°C). What to do with the remaining water? You can make jelly now and use it again when you need to re-apply, or store it in the fridge to re-apply later. When all the water is used up, you can dissolve the gelatin in hot water and apply that solution to the build plate. I designed this build plate coating with IceSL, and I've included the design source (mortar.lua) if you want to make one yourself. There's no need to print it, though - it's mainly just an eye-catcher to remind you to prepare the coating before printing. I found out about this recipe on reprap.org/wiki/Bed_material, which mentions a Jello solution. I had never heard of it before and couldn't find any forum posts on it, so I decided to try it myself using gelatin instead of Jello. It worked out great, even though I messed up the original recipe by not dissolving the gelatin in hot water first. My print plate is a 0.5mm carbon sheet without any special treatment or coating. It has good adhesion for ABS and PLA, but not for PETG. With this coating applied to the carbon sheet, I don't need any kind of support for ABS, PLA, and PETG. I've printed with 0.1mm layer height including the first layer height, even for PETG, and it stuck perfectly to the heated build plate. I print at typical temperatures for PLA (65°C), PETG (90°C), and ABS (110°C), and switch off the heating only when the print is completed.
