I'm sure you're right about the Top Layer Don - but if we combine with a few other comments here - then one solution (not to perfect - just much better), would be to set the Slicer to have a 0.1mm Top, Bottom and Outside Layers and the rest much coarser ....I'm sure the Slicer I can't remember the name of could all this automatically in the latest version - giving a much better surface on all sides, faster printing time and consume less material and keeping strength of Print. The Tester said it was a very big leap in Slicing Tech .... I just wish my memory could take such a leap forward (or should I say back to before my accident ).No matter, as others has given a few clues here - it can be improved one way or another.Per
George:With an FDM printer a part is ALWAYS going to look like it's made out of Lincoln Logs, it's just the nature of the beast.If you print with ABS, you can solvent bond or vapor smooth using acetone. PLA needs some NASTY solvents for a solvent bond, and vapor smoothing is not recommended. Well maybe if you stay upwind in the middle of an open field you could do it. Your only viable option with an FDM printer is decreasing your layer height. You still get the Lincoln Log look, they're just harder to see. I was amazed at the difference in surface finish between a 0.2mm layer height, and a 0.1 layer height. Of course your print time increases proportionally. If you want a really smooth sidewall with an FDM printer using PLA, about your only option is filling and sanding. Unless it's something I REALLY care about, I just tolerate the Lincoln Log look.Don
