Kapton tape (a registered trademark of DuPont) is a polyimide film. Created for the aerospace industry in the 1960s, Kapton tape as a flexible adhesive tape that is stable over a wide range of temperature, from -269C to +400C. The film was used for many awesome projects like the Apollo Lunar Module.
The tape was then discovered and utilized widely in the Electronics manufacturing industry for its electrical isolation properties in addition to the thermal stability. 3D printing, in particular the RepRap Community, discovered a new use for the robust material as a bed surface.
Kapton tape comes in large rolls which allow you to cover the entire bed with a single sheet. Unfortunately, applying the tape is tricky since it is easy to trap air bubbles underneath or make creases. In this guide we will show you an easy way to apply Kapton without trouble.
Step 1- Create Soapy Water Mixture
Step 2- Remove Glass Bed
Step 3- Spray Bed With Soapy Water
Things are going to get messy at this point. Either lay down some towels or do this some place where you don't mind getting water everywhere.
Spray the entire surface of your glass plate with the soapy water. Do not be afraid to use too much.
Spread the soap around and make sure that the entire plate is covered. If you miss a spot, the tape will get stuck there and you will have a problem.
Step 4- Lay Down Tape
Step 5- Squeegee Water Out
Step 6- Cut Tape to Size
Step 7- Bake Moisture Out
Step 8- Apply Hair Spray or ABS Juice
Step 9- Print
And that's it! It is really that easy. Now, get that Kapton tape on your printer and enjoy!
