<p>I am new to 3D printing but have been in CNC Machining for a few years. I have a part I am trying to print that is a cylinder 1.000 in. in diameter and has a .200 in overhang starting at 1.300 in. In other words I am printing a 1.300 in. cylinder that is 1.500 in. tall that at 1.300 in. its diameter increases by .200 in. </p>

<p>When I first printed the part the overhang had sunk or fallen out. Not by much and is still usable but made a crappy finish. What would I need to do in order to have the overhang not drop as the base layer extended outward .200 in. at 1.300 in.?</p>

<p>I tried slowing the feed rate but that was worse. I also lowered the temp to 195&nbsp;°C.</p>

<p>I am using a Monoprice Select Mini running at 200&nbsp;°C and a 1.0 Speed (Not really sure what that feed rate is in terms of mm/s). Based on what I've seen so far I would increase the speed and keep the temp at 200&nbsp;°C.</p>

<p>Any suggestions, I hope I have explained my problem well enough.</p>

Furthermore, the bore of the item isn\'t supported either, it is bridging.</p>\n\n<p>To print overhangs and bridging without sagging, one should activate the generation of support material in the slicer.</p>\n\n<p>Generally speaking, PLA (judging from the print temperature) doesn\'t need to be printed with a raft and would be better served with a <code>brim</code> for bed adhesion, unless you have a perforated bed. If you have to print in the shown orientation, then you should activate support generation in your slicer.</p>\n\n<p>For this part, however, there is a better solution: it is of very simple geometry and it doesn\'t have to be printed as shown but equally could be printed "upside-down" by being rotated around the X-Axis by 180° in the slicer. This has two benefits: it removes all unsupported overhangs an avoids support structure, making the wasted material pretty much nonexistent.</p>\n\n<p>I strongly recommend taking a look at my <a href="https://3dprinting.stackexchange.com/questions/6726/what-special-considerations-must-be-taken-when-designing-parts-for-3d-printing/6830#6830">3D Design Primer</a> and the excellent question on <a href="https://3dprinting.stackexchange.com/questions/10636/how-to-decide-print-orientation">How to decide print orientation?</a> and then delve into further reading: </p>\n\n<ul>\n<li><a href="https://3dprinting.stackexchange.com/questions/250/how-to-print-an-overhanging-arc">How to print an overhanging arc</a></li>\n<li><a href="https://3dprinting.stackexchange.com/questions/686/how-can-i-improve-the-overhang-angles-my-printer-can-successfully-print">How can I improve the overhang angles my printer can successfully print?</a></li>\n<li><a href="https://3dprinting.stackexchange.com/questions/5529/is-there-any-setting-that-could-allow-me-to-print-this-overhang-without-support">Is there any setting that could allow me to print this overhang without support?</a></li>\n</ul>\n'}, {'answer_id': 11152, 'author': 'Peter', 'author_id': 18800, 'author_profile': 'https://3dprinting.stackexchange.com/users/18800', 'pm_score': 0, 'selected': False, 'text': "<p>It appears that your part could be printable upside down.
