Показать описание
Retraction is a super useful setting you can use within your slicer to greatly improve the quality of your 3D Prints, but it's very misunderstood! In this 3D Printing 101 we'll go through the basics of what retraction settings are and how you can tweak them.

You'll be amazed by how much of a difference correct retraction can make!

Travel Speed is the second most important setting for preventing Stringing. The Faster you get from A to B on a travel, the less time there is for filament to ooze out.

I just got my first 3D printer last week, and I'm taking things really slowly, just printing a small thing every now and again before I move on to big stuff.
But one of my favourite things so far is the amount of good info that's out there, like this video.
I pick up one or two good tips from every video and they always make total sense.. It's a really fun journey!

Thank you !!! After I changed my nozzle from 0.4mm to 0.5mm I was plagued with stringing, spent countless hours troubleshooting with no luck.. I also use Flexion extruder. I just copied your Simplify 3D settings and my stringing is gone completely. You are the most useful YouTuber by far, very useful video! Keep doing the good work.

Incredibly well done! I learned from this, keep it up!

lets be honest Angus, Simplify 3D is probably not the software used by the most users, due to its high cost.

most of the users will be using the free solutions available, like slicer and cura, in which the settings that you showed will be a little more hidden and difficult to change.

so i think that a video for that free options would be appreciated by many of the viewers.

other than that good job, and great video.

You should also consider lower temparature setting if you have excessive stringing. Also fan speed can affect stringing but not as much. Another thing to take into consideration is to determine your max retraction distance. If you have all metal heatbreak AVOID PULLING FILAMENT INTO COLD END! This can cause clogging or heat creep and ruining your print, especially when printing with PLA. Measure the max distance between cold end and hot end. Also you can try speeding up travel moves.

Just started my 3D printing journey and came across your channel. Really like the straight to the point and easy to understand explanations (unlike other channels that love to brag about their millions of upgrades and never get to the point lol). Anyways thanks, you've helped me a lot finding some of the problems I was having!

I know this is an older video, but I just wanted to tell you that it has helped more than recent videos have about the same thing. Thank you for sharing your knowledge with the world!

WOW! I followed this info, using a similar test print on my Longer LK5 and went from strings to almost NOTHING on the final! Awesome!! Thank you!!!!

I got my Neptune 3 Pro last October and never knew about these settings or why my prints were turning increasingly 'hairy.' Thank you so much!

When using coast at end for 0.2mm what can happen on many small retracts on detailed small prints is that it when the extruded plastic amount is almost (or getting close) the same as the coast distance, it will majorly under extrude. This is really easy to notice as you change layer heights from 0.2mm to 0.1mm as less filament is extruded and you notice this effect much quicker. It is a solution, but it needs to be calibrated and set for each layer height.

has anybody ever tried to deliberately "grow" those ooze-tree structures? they're kinda intriguing in theyr own right.

Lots of videos refer to 'getting your printer dialled in', but none of them go into a step by step process to say which settings will make what sort of change or a sequence of which settings to tinker with and by how much. A series of tutorials in a separate playlist? And print the same thing on the same printer to illustrate changes. I imagine that is what your maker coin was for initially.

Fusion 360 is a magic program. Getting to grips with it slowly. Can't believe how powerful it is overall; CAD is just the tip of the iceberg (and the only bit I will ever really use I think).

Sooo happy to have da vinci mini... out of the box, no calibration - perfect print quality... And retraction is very noticeable in it :) it makes a "squeek", each time, while retracting to a new position.

Awesome to know what the theory behind the "Squeek" is.

These fine calibration details - that's worth paying for. Seriously - you take a machine out of the box, and it simply works. A professional had already calibrated it to perfection. It would takes hours to get things straight on my own. Perhaps days...

Iv'e just finished building my second 3D printer, and went through your video to help me fix my really bad stringing issue, printing like a boss now!
And for the Naysayers about Simplift 3D being too expensive, I have a mate that wishes he had S3D like I do, he absolutely loves the supports that S3D has compared to the latest Cura he uses.
I tried a number of the free Slicers, but S3D is the best for configurability I have found so far. Also you have to consider I built my printer, it's not standard, but hundreds have made similar machines to mine (Hypercube). It is definately not a cheap printer, but it's far from expensive.

This is awesome, thank you! I really appreciate the detail for flexible material. I will be looking into those settings for Cura.

Hey Angus, great video as always. I really love your work and presentation style. I think you're doing a freaking fantastic job and all your videos have undoubtedly helped thousands (even millions) of people get into 3D printing successfully! Thank you again!

Most excellent episode of Printing 101! These settings helped improve my prints 110% on the gMax 1.5XT+. Thanks for sharing this very valuable bit of information Angus!
