Topic: Different printing results with different slicer settings

Hi, everyone. This passage is mainly written for  those who uses 3D printer for the first time.
I want to share some printing results with different slicer settings. Hope this will help some of you.
 
Printer: Geeetech Acrylic Prusa i3
Filament:  PLA 1.75mm (also fits for 1.75mm ABS)
Nozzle diameter: 0.3mm
 
1. Infill density
     15% vs 30%
http://www.soliforum.com/misc.php?actio … mp;preview

As you can see in the picture, there are still many holes unfilled with 15% infill density. But the model is full filled with 30% infill density.

2. Skirt loops
      0 vs 3
http://www.soliforum.com/misc.php?actio … mp;preview
  Obvious difference as you can see in the pictures above. Personally, I suggust you'd best print at least 3 loops of skirt, because the filament may not come out from the nozzle immediately. The printer will print the skirt first.

3. Brim width
     0 vs 1
http://www.soliforum.com/misc.php?actio … mp;preview
  If the brim width is 0, printer will print 100% as same as the stl file. if the brim width is 1, printer will printer another brim, as you can see in  the right side of picture.

4. Extrusion of first layer
    100% vs 200% vs 400%
http://www.soliforum.com/misc.php?actio … mp;preview

5. Vertical shells:perimeters(minimum)
     2 vs 4
http://www.soliforum.com/misc.php?actio … mp;preview

Look at the edge of these 2 models. If perimeter is 2, there are 2 loops of brim on each layer, and the model has a better look.

If you think there's something worth sharing,  I will be glad if you leave your advice.

Re: Different printing results with different slicer settings

1 / something is wrong with the calibration of your printer... 30 % is waaaayyy too much, even 15% is too much (if strength is not your main goal)...

my models are printed with infill between 10 and 12% and no holes...

2 / 3 loops of skirt is too much.. only one loop is necessary as this function is only to fill your extruder nose before the start of the print of the main model ... if you need more than one loop, again there is a problem somewhere (or your model is REALLLY small) ...

3/ Brim is a function for the problems of 'warping" to "stick" the model to the bed... the number is for the number of mm (width , use only one layer in general) of the band that will be add to the base of the model  .. 4 or 5 mm is good if your model use sharp angles (like a cube).. you can use even more for a really big sharp angle model...

1. It depends on the character of the printer, maybe 10% infill is good enough for some printers but some need 20% infill. That I raise the infill to 30% does not mean my printer really need 30% infill to have a high quality printing. I just want people to know what will change if I change a parameter.

2. For my printer, I don't even need a skirt. Just for an obvious difference.

3. Thank you for your prompt, because I don't know what the brim is used for.

And thank you again for your suggestions. smile

In theory and even practice if your printer is calibrated correctly it should perform the same as other printers in its class. The only deciding factor would be the quality of your hot end. A well tuned type "A" printer should print the same as another model next to it with same settings.

Re: Different printing results with different slicer settings

Holy crap, so if I used the 40% default infill for slicer is too much ? But I tought that the 2 succesfull printing so far looks stragely strong.

Re: Different printing results with different slicer settings

if you need a strong piece (like a printed wrench), you can go with an infill of 50% and up.. (even 100% if you need a really strong piece) but if you need only an infill for an 'art model' just to support the outer surface (and to not waste plastic) , 10-15% infill is enough...

if your printer NEED 40 % infill to make good pieces, some of your other parameters are way off ... (like the calibration of your extruder or parameters related too..)

Thanks for making this - I don't have any experience with PLA and many people can benefit from actually seeing different options put into practice.

However, I do agree that most prints only really need 15-20% infill and the infill should have holes.  The idea is to only use enough plastic to support the top sections of the object and make the object rigid but not solid.

Many of your prints do look good to me but others more experienced with PLA may offer different advice.

In a way,I agree with you. A bad hot end may cause clogging during printing.

If you just want to print a model, I suggust below 25% infill. If you want to print something strong, then a higher infill is considerable.

In my own experience, I think the diffrence between PLA and ABS is temperature setting. I change nothing but temperature in slicer settings when I change filament with ABS. If you see the bottom of the model bent, you can raise the temperature of bed. If necessary, you can smear a layer of glue.

Re: Different printing results with different slicer settings

Being new to 3d printing I found this useful regardless of the exact % settings. I see this post as a great point of reference of what each of the settings actually do. Thank you.

Re: Different printing results with different slicer settings

Agreed with your statement. As a beginner it is a great place where anyone can easily learn about the 3D printer.
I'm going to apply them on myself.
