# How should I go about printing easily removable rafts?

I have had a 3d printer for a while now, and I have a lot of the quality settings dialed in pretty well, but one thing that constantly bugs me is removing the raft from my finished prints. I am using Repetier and I have set the air gap to 0.2 mm. That led to much better results than the default 0, which were impossible to remove at all, but it is still not great. Are there any settings I should look at changing to get easier to remove rafts? Does the filament affect this? I am printing in Hatchbox PLA at high temps. I have a heated bed, and reducing the temp on that did seem to help. Maybe it keeps the layers on the raft from fusing with the layers on the part? Any help is greatly appreciated. Thanks.

• Not an answer, but: Why do you use a raft at all? Most people don't. Sep 27 '17 at 22:08
• I thought that was what everyone did to make sure the print stuck to the bed. I am a newb, there wasn't a whole lot of thought behind it. lol Sep 28 '17 at 1:47
• Probably the raft density is too high. This rafts should be like supports 40 or 50%, I had the same problem when I started to print but I never use this parameter due the part gets sticky on masking tape. Sep 28 '17 at 5:28

• MatthewFegan as TvdZ said - using raft is not so common. Try paper glue or hairspray, personally i use paper glue and it's just incredible, it's also clean (as hairspray spreads itself everywhere) and it's also cheap nad easy to cleanup (i use warm water). i would use raft only for object with very very small footprint.

• Is letting the nozzle cool and heat up again just a hack to get the printer to pause? In that case, you could just use G4 Sxx where xx is a number in seconds, instructing the printer to wait. Oct 23 '17 at 6:23
