Cure for The Common Curling: "The Brim" June 04, 2012 06:36PM |
Here is a way to defeat curling/warping in your prints.
The term might be taken, but I call it a "Brim." If anyone wants to coin a new term for this, make a suggestion
Using the program Slic3r I add a "skirt" of 5 to 15 loops at a "zero" millimeter distance from the object I am printing.
[slic3r.org]
This adds a brim (like a cowboy hat ) that keeps the object "spot welded" to the plate and absolutely stops all warping and curling.
The additional surface area, combined with the rounding of sharp points on the bottom layer denies any possibility of curling or warping from the bed.
To remove the brim, you need simply fold the plastic back and forth, and it snaps off
I hope to see this method implemented in the various slicing programs; as its own unique feature.
Try printing with a Brim today, and see if it helps the quality of your prints
-Happy Printing

Good idea to automate the process, I'll definitely give it a try next time I print something huge (mario shell i'm looking at you)

Glad you gents found it useful!
I have been using cheap Chinese filament (it lifts terribly even on hot glass) I needed to defeat some big lift/warp/curling troubles.
So after two weeks of frustration, I reverted from a glass plate back to a blue tape surface and came up with "the brim"
The adhesion is VERY strong with this method.
It was the use of cheap filament that drove me to this; but I now know this is a viable option to defeat curling in "tricky" prints, even with expensive/high quality faberdashery filament
I am happy to announce that I can now print with cheap filament with impunity!

@banthafodder Very cool. Glad it helped your print! I would love to see a pic when your object is ready for public consumption

This is a very good idea which I've also used in the past. But does't this have a name already? It's called a skirt in both slic3r and skeinforge.

I look at this as an "off-label" use of the Slic3r skirt function. I do indeed use the skirt function to make the brim.
The skirt function has been used primarily as a means to prime the nozzle; Most people do not use the skirt function to fight warping. Most people do not use a skirt 15 loops thick attached to to the object
I stumbled upon this by trial and error; and it looks like you and I are probably not the only people who have experimented with this.
I am happy to get the word out though! When I figured this out, I was able to use it to solve many wonky curling, lifting, warping problems.
I hope to see the slicing programs adopt a "brim" function as a standalone feature, so that we can have a "skirt" to prime the nozzle, and a "brim" to defeat curling, warping and lifting.
Happy Printing

I used the 'Brim' setting in my number counter, 150mm x 150mm single print, did the job perfectly, thanks!

Does it still work with a glass covered heated bed? After some great warp-free prints past few weeks, I finally did a large plate and had some lifting, I'm in love with how easy the prints are to remove from the glass after it cools but I'd rather not spend another 15 continuous hours only to find out it's only suitable for printing on tape.

Yup, it still works wonders on glass. I reverted back to blue tape because the cheap Chinese filament I was using would not stick to glass at all.
The brim will defeat warping on glass and smooth surfaces as well.
I now put brims on just about all my prints; even when printing easy objects with high-quality filament.
Why waste my time with warped prints anymore?

Wow,
I am flattered to hear I had anything to contribute to RichRap
That's great!
@RichRap I am actually going through your whole blog right now; picking up all the lessons learned I can! Thanks for your great Blog!

Ok, let's take a reality check here. Yes, "the brim" will offer some extra adhesion for the object's first layer. SOME. Not infinite. The reality has not changed, as soon as the warping forces exceed the grip, the object will rip the brim off the build plate and warp. Like this:
The claims put forth in the first message, like absolutely stops all warping and curling are not true. Don't take me wrong, I wish they were! And even in the pictured object, the brim delayed the warping for so long that I ended up with an usable object, unlike on my first try without the brim. But warping is still here with us and requires consideration of what can be printed from what.
