We have tested out many different solutions to stopping warpage when 3D printing and they have all come in the form of adhesives so far. This latest product is decisively different. The Coro pad is a new attempt at stopping warpage and keeping those prints sticking to the bed. The claim is to stick the coropad to your print bed and then print directly onto the pad. The prints will then stick to the pad and then at the end of the print you remove the print form the pad. The pad stays on the print bed and you just keep printing over and over again.
We have tested out the pad and found some promising results. It does work well in that your prints will stick to the bed. You need to ensure that you have a completely flat printer bed e.g. glass or acrylic and that you have offset the Z height to accommodate for the thickness of the pad. Once you have got this right then it’s all systems go. If you have automatic levelling of the print bed then you need to ensure that the pad you use fits your print bed right to the edges. If it doesn’t then as your printer levels itself, the Z height won’t be right. Checking the Coropad website, it comes in many different sizes so we recommend getting a pad that is exactly the same size as your print bed or even bigger and then trim it down.
To apply the Coropad was easy, you just peel back the adhesive sticker on the back of the pad and then place it onto the print bed. Be sure to do this accurately and carefully so you don’t trap any air bubbles under the pad as this defeats the object as your bed won’t be completely flat. Once stuck onto the prin tbed the Coropad is extremely versatile. We found that we could print multiple prints one after each other and remove them with relative ease. We used the typical paint scraper to get the prints off and found this worked well. Small prints with a small surface area were extremely successful and we even completed a nest of prints. This came out a success.
We then tried to print a stacking box by creative tools that had a large surface area and pretty much filled the print bed size. Again, this stuck great to the Coropad, however we did find that it was hard to remove from the bed and the part became damaged it was so well adhered. Coropad advised us to slightly offset the Z height to ensure that the first layer is not so close to the pad. This is the key, getting the Z height just right. It’s worth spending bit of time doing this to ensure that you get the most out of the Coropad.
Our overall thoughts of the Coropad are very positive, it does what it says on the package and is a different clean alternative to adhesives. Some adhesives can get messy and then you have the dreaded issue of running out and having to re-order. With the Coropad you don’t have this issue. Also there is the safety aspect as well. Many adhesives have a flammable warning on it, when with the Coropad you don’t have that issue. This is a win win situation when using in environments such as education.
We’re happy to say that this is a product that we wold use again. If you would like to find out more then visit their website here https://www.corotechnology.com/english/c-stick/
