Option 1

WIPE WITH RUBBING ALCOHOL

Wiping the build platform with 91% isopropyl alcohol (available from any grocery store) before a print can help improve print adhesion. Put a small amount of rubbing alcohol on a paper towel and wipe down the entire print surface. Wait for the alcohol to dry and start your print. The alcohol cleans the build surface of any dirt, grease, and/or residue that may not have been visible.

Try printing. Is the print adhesion better?

Option 2

SLOW DOWN FIRST LAYER SPEED

Slowing down the speed on the first layer in the slicing software helps prints stick better. To do this, follow the steps below:

1. Click the "Edit Process Settings" button on the bottom left-hand corner of Simplfy3D®

2. In the Process Window click "Show Advanced"

3. Click on the "Layer" tab

4. On the right-hand side, change the "First Layer Speed" to a value between 25% to 50%

5. Finally, click "Update Profile" at the top of the window and re-slice your object

Try printing. Does the first layer adhere to the build surface?

Option 3

CLEAN PRINT SURFACE

Using a sheet of 220 grit sandpaper, very gently wipe in one direction working your way across the build platform. Only light pressure is needed on the sandpaper as you wipe. The goal here is not to remove material, but to create striations that help your print stick. Always work in one direction, either side-to-side or back-and-forth but not both ways. Sanding in this unidirectional motion improves print adhesion.
