Print improvement Hello, I have been 3D print for some time now. By no mean I am an expert. I have just printed this object (in pics) I have never printed something this big and odd in shape, it took a wooly 10 hours!!!! And I wasn't sure it will come out ok, as a result, it didn't come out too badly but messy, tho need a lot of cleaning tho! I am seeking for advice in how to shorten the print time without reduce the rigidity and how to reduce the messiness and any suggestion on how to make it better in general. Thank you vin advance https://reprap.org/forum/read.php?262,597034,597034#msg-597034 Thu, 13 Aug 2026 05:53:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,597034,600593#msg-600593 Re: Print improvement https://reprap.org/forum/read.php?262,597034,600593#msg-600593
It also looks like you might be over extruding a bit. Try setting your extrusion multiplier to .90 instead of 1.0]]> tmorris9 Printing Thu, 24 Dec 2015 19:29:53 -0500 https://reprap.org/forum/read.php?262,597034,600432#msg-600432 Re: Print improvement https://reprap.org/forum/read.php?262,597034,600432#msg-600432 Also keep in mind that if the retraction is too fast you only stress the filament and extruder.
And, if using longer retractions you can suck in air through the nozzle - that is to be avoided...]]> Downunder35m Printing Thu, 24 Dec 2015 09:01:10 -0500 https://reprap.org/forum/read.php?262,597034,600289#msg-600289 Re: Print improvement https://reprap.org/forum/read.php?262,597034,600289#msg-600289

The retraction speed should be close to the fasted your exruder can handle to keep the time losses short.]]> Downunder35m Printing Wed, 16 Dec 2015 20:22:21 -0500 https://reprap.org/forum/read.php?262,597034,597472#msg-597472 Re: Print improvement https://reprap.org/forum/read.php?262,597034,597472#msg-597472

Once you got some experience it often comes down to look and feel.
You see the print and you know what should be done to correct it.
Play around with the temp and retraction to get rid of the last spider webs.

Would you mind telling me more about the retraction? Did you mean the retraction on the extruder motor? And what can I do to fine tune it?

Thanks again.]]> rich1812 Printing Wed, 16 Dec 2015 09:46:53 -0500 https://reprap.org/forum/read.php?262,597034,597462#msg-597462 Re: Print improvement https://reprap.org/forum/read.php?262,597034,597462#msg-597462 You see the print and you know what should be done to correct it.

Well, if there is one thing working then it would be bridging LOL
The surface looks quite rough, might be too high in temp.
And the strings are a result of the retraction not being set properly.
With the settings correctly the part should come out clean and with little to no need of cleaning up.

Thank you for the reply.

Considering initially I didn't think it could be done at all, I thought the whole thing would collapse and cave in during printing. LOL.
You are probably right about the temperature. I just printed the second half of the helmet in a lower temp. It has much fewer "spider
web" ]]> rich1812 Printing Wed, 16 Dec 2015 07:47:56 -0500 https://reprap.org/forum/read.php?262,597034,597145#msg-597145 Re: Print improvement https://reprap.org/forum/read.php?262,597034,597145#msg-597145 The surface looks quite rough, might be too high in temp.
