Small (almost round) objects get to much material

Posted · Small (almost round) objects get to much material

Hello All,

Just resently upgraded to th Olsson block head with changable nozzle and trying to print smaller prints with the 0.15 mm nozzle.

I tried to print a small version 4 cm height of a full body scan.

The whole print goes well like legs and arms but with the head the print goes wrong. It seams that at the head it flows to much material in the round going movement so it looks like the person is waring a scarf and beany instead of the shape of a head.

Print settings 0.15 mm nozzle, 0,3 mm wall, 0.1 layerheight printspeed 40 mm/ sec.

How co i tweak the settings around the head to get a better result.

Sorry no photo yet available, can add that later.

Hope to hear.

Mark Heiden

    I think 0.1mm layer height on a 0.15mm nozzle is a bit high, maybe try 0.05mm layer height? Print will take twice as long but it look better anyway. Too bad you can only see it at the end of your print (although you could print the head only to see whether there is improvement)...

    I am with Labern on this one :)

    If the nozzle stays on the same place all the time, the filament doesn't have time to cool down

    because the next hot layer is already being deployed, and the heath of the nozzle keeps melting whatever has cooled down already.

    If you don't want to print two, you could also print a small tower next to it.

    How small are we talking about?

    It's possible to print object that are 1cm tall with fair results even smaller it all depends on the model and the complexity

    The model in the picture. It has small holes from 0.5mm and is of a total size of 1 cm.

    The vertical holes - you need to exaggerate them by about .3 to .5mm to get the to be the right size.

    The walls may be too think to print. If they are close - just lie to Cura and tell it you have a .35 nozzle. In fact start with .3mm and if that shows walls in slice view then gradually increase until you find the moment where the walls disappear. .35 is pretty safe - the quality will be reasonable. But much smaller and the quality of the object will get quite bad so you could then buy a smaller nozzle. Stores for smaller nozzles very depending on country - what country are you in? Please update this in your profile.

    Thanks for the advice, i will give it a try and print two at the same time to see the differences.

    I have another test object i could try that is less heigh so i could see the results earlier.
