Improve 3D printer adhesion

3D Printing Help Centre

3D PRINTING HELP CENTRE

In the 123-3D help centre, we answer all your questions about 3D software and printer settings, problems you may experience during or after 3D printing and other 3D-related topics.

How do I improve the adhesion of my 3D printer?

Good adhesion of the filament to the print bed is essential. When the first layer does not adhere well to the print bed, various printing problems can arise. Many printers have a heated print bed so that the filament does not cool down too quickly after it comes on the print bed. Too great a temperature difference can lead to bonding problems. Of course, there can also be problems with the printer settings, but you may also need tools to optimise the adhesion on your print bed.

What is Kapton tape?

One way to improve adhesion on a heated print bed is Kapton tape. This is very thin, transparent tape that can withstand the high temperatures required during 3D printing. You stick this tape over the print bed, it is important that no air remains under the tape. You can use the Kapton tape for several 3D prints before you have to replace it.

What is 3DLAC adhesvive spray?

An alternative to Kapton tape is 3DLAC adhesive spray. You spray the heated print bed with this spray before you start printing. At a temperature of 100-110 degrees, the spray is extremely sticky, so that your printed object perfectly adheres in place. When the plate has cooled completely, your 3D-printed object can be easily removed. The spray is water-soluble, making it easy to clean your print surface after printing.

Can I use ammonia to make my 3D print adhere better?

Another way to make your print adhere better is to use ammonia. You do this by cleaning the print bed with it, so that the filament can adhere well to the degreased surface. Use gloves during application to protect your skin. Due to the ammonia, the 3D print is printed on a smooth surface, which gives a glossy result to the bottom of your printed object. The downside of ammonia is the smell. We recommend that you only use this in a well-ventilated area.

The distance between the print head and the print bed is too large

It is also possible that the distance between the print head and the print bed is too large. The distance does not have to be great to be able to print. If, for example, a business card or A4 paper fits with difficulty, the distance is already good enough. If the distance is too great, the pressed filament will not adhere well to the printed circuit board.
