Whenever I finish a print, the raft sticks to the print so hard that I have to file or sand it off. This is very time consuming and does not leave a smooth surface. Is there a way to prevent this?

Which slicing package are you using? In Cura there is setting for Raft Air Gap which you can increase, there may be a similar option in whatever you are using. Alternatively, you may be over extruding but you would probably see some other print issues at the same time. -
May be extruder is too close to the bed? , post a picture that would help to determine whats wrongComment

Extruder is at correct height. I replaced the bed with a new manufacturer’s sheet and releveled the bed. It seems to make no difference, and I literally have to chip the print from the bed and the raft from the print.Comment

Did altering the raft air gap in your slicer have any effect?Comment

Yeah, the Flashprint rafts are too dense on the top layer. I found this a bloody pain too.
You can download Cura for free & set the density of the upper raft layers to say 85% which makes then very easy to peel off.
The Flash-Print rafts are best removed by using a Big Craft-Knife & teasing the raft off, but I often cut myself however careful I am with the Flash-Print rafts. Unfortunately, they have no settings adjustment, so suggest Cura as a freebie.Comment

I’m using ReplicatorG, and there is no adjustment. I think I’m going to try Cura.Comment

Have you tried printing without a raft? If the surface is small use a brim instead. I have yet to do a print that needs a raft.Comment

What sort of bed do you use? Pretty much everything I try to print without a raft goes wrong.Originally posted by bernbout View Post
I am having a similar problem to OP (though not quite as bad). I'm doubly puzzled because when I first discovered the raft feature, it worked perfectly and I've no idea what I've changed to change it. :?
I'm using Mattercontrol.Comment

If one part of the raft goes off easily and other side to strong it means your bed isn't leveled correctly

Auto bed leveling is amazing once you have it working properly, it's a bit fiddly to adjust offsets to start with but it made the world of difference to my prints. I always use a raft as well.Comment

I use a borosilicate glass bed with a glue stick.Originally posted by Hairyloon View Post
Nothing else. I NEVER print with a raft. They always stick and will certainly spoil your bottom surface - guaranteed. Rafts along with tape were used when Reprap started. With today's surfaces these 2 are not needed any more.
I wash the glass under warm water and dishwasher liquid and drip dry. After an application of cheap gluestick I print about 5 models before a clean up with water. No Rafts. No brim.
If the model is such that only a small surface touches the bed, I use a single layer brim diameter of 10 mm at most.
To remove the model after printing, I use a paint scraper, place it at the base and give it a sharp tap with a small hammer to dislodge the model.
I use the Cura slicer provided with Repetier-host and always print from sd card.Comment

bern bout have you tried aquanet? I use a glass bed and after i wash give it about threee good coats of aquanet. then after every print give it another good coat. I wash it about every 20 coats or so.Comment
