Hi

I have some trouble with objects in smaller size (scale reduce with FlashPrint). First picture looks like good, but picture two shows some "errors". I don' know what the problem could be.
Any ideas?

Ok..

Yes, your problem is easy to fix, you are not using a raft or supports.

#1 you need to use supports to print that frog. Trust me.. I have printed literally hundreds now for people.





And if you want to go super small... as in...




You print at 0.15mm layer height and about 30ms feed rate, and a lower heatbed temp, if you usually use 110c, drop it down to 106-107c, the smaller prints cant handle the heat and make edges rise easily, and thats all due to heat. The bigger the item, the hotter you go, but dont exceed 115c

Hi Geoff

Yes, I didn't use raft or supports. I thought this is only necessary when I print difficult objects, like a bridge or so. I'll test it with supports (I hope I will not print hundreds of frogs... ;-) )

Thanks.

It's all down to angles on the frogs chin for that one, the arms could get away with none but the chin just has too much of an angle.

If you use makerware try the preview function, it shows you all the supports and things that will be printed at runtime and you can also check out each layer of the print with a nice slider bar, so before you print you can see if there will be areas that are printed in the air, they will be a different colour in your preview.

Hi Geoff

Left picture (orange) is printed with support, right picture (blue) is printed without support. Left one PLA is from another than the right one. So I think this could be also the problem. Next one I'll be test with other temps. My problem is also that I'm testing with different PLA's from different
companies and every company has another coil (correct word?).

Wow that Blue PLA looks excellent, and you said without supports?

I might go and try the Green PLA I have and see if I can do it, I'm impressed the blue layers came out so well underneath, there is no visible overhangs at all.

Yes, I know and I think the pla from FF is not the best quality. I have ordered new pla (not from FF, excellent quality...they say...) and will try it.


The pain is, that I must always change the filament from the new role to the FF role! I need a machine which can do this for me!

I printed another thingiverse object, the first one comes out great, the other one very bad with the same settings! (it's nearly the same object). After replace the 3M blue tape it cames
out better.
