As with any 3D printing, resin printing is based on printing one layer after another. For this, the model needs to stay perfectly in place on the print plate and critically needs to stick to it. If you’re having issues with your resin prints coming unstuck, it can be a pain to diagnose why. To help you out, we’ve drawn up some troubleshooting tips for why your resin prints aren’t sticking to the print plate.
How to Make Your Prints Stick to the Print Plate
One of the key factors in print plate adhesion is texture. A textured print plate has a larger surface area than a smooth one. A fine texture can make a big difference. Still, a rough texture can make even more and is recommended for bigger, heavier prints.
To add some texture to your print plate, try sanding it with medium-grit sandpaper. Just make sure to thoroughly clean it afterward; otherwise, you will introduce many specks of dust and other unwanted particles into your resin.
Resin needs to be warm to properly react to the UV light and harden. If your resin is just a little too cool, it might not react enough to set properly. Similarly, if your print speed is too high, it might not have enough time to react and set. And if the power is too low, the same thing can happen to result in collapsed prints.
Over time using the same resin will leave small amounts of set resin in the vat. These can interfere with the structure of your print and with the setting process. To get rid of these, you need to filter your resin. Especially if you’ve left the resin sat in the vat for a few days, some of the pigment and other components can separate. This results in inconsistent quality in prints; however, it can be resolved by remixing your resin.
Hopefully, these troubleshooting tips give you a good starting point to resolve issues where your resin prints struggle to stick to your print plate. If you’re got any other tips to share to resolve this issue, let us know below.
