<p>Dear experts and 3D printer users;</p>

<p>I am a beginner in 3D printing field. I read couple of answers in forums and i cannot find exact answer to my problem. </p>

<p>Printing quality dropped when i try to write vertical axis (i mean, columns). There is no problem in horizontal axis. </p>

<p>My column width must be 0.5 mm, and printer nozzle diameter is 0.4 mm. I think I should write 0.5 mm column with 0.4 mm nozzle with ease. </p>

<p>I added messy structure to this post and you can find writing details below. <a href="https://i.stack.imgur.com/VbBo0.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VbBo0.jpg" alt="Printed Structure"></a>
What do you think? What is your suggestion to overcome this problem? </p>

Basically, you are asking the printer to lay down tiny blobs of filament, one of top of another. You have two options:</p>\n\n<ol>\n<li><p>Use a finer nozzle (e.g. 0.1mm). However, such nozzles are reported as being very difficult to use.</p></li>\n<li><p>Switch to a different printing technology (e.g. SLA).

It is simply too big to accurately print a structure that tiny.  An integral part of the filament deposition is the "smearing" of the molted plastic, that clearly can\'t happen if the structure is about the same size of the nozzle bore.  Also the printed structure is too flimsy to resist the "suction" of such a big nozzle moving away.</p>\n\n<p><strong>I would suggest to use a smaller nozzle and/or increase the size of your pillars</strong>.  A good combo would be 0.2mm nozzle with 0.6mm or 0.8mm pillars.  For these small details, it would be best to have a pillar size that is a perfect multiple of your nozzle diameter.</p>\n\n<p>Other settings that will help you:</p>\n\n<ul>\n<li>reduce the print dramatically (try 20 or 30 mm/s)</li>\n<li>use retraction (or increase its amount/speed)</li>\n<li>make sure your cooling fan is 100%</li>\n<li>use a sensible "minimum layer time" (try 10 seconds for a start)</li>\n</ul>\n\n<p>The first two settings should reduce the force/impulse applied by the nozzle on the pillar.</p>\n\n<p>The latter two should make sure your pillar is "solid" when extruding a new layer on top of it.</p>\n'}]
