In this video, I'll guide you through every setting in Ultimaker Cura's infill settings, so you can understand how to optimize your 3D prints' strength, weight, and print time. Infill is the internal structure of a 3D print, and it plays a critical role in determining its strength and durability.
First, I'll show you how to choose the infill pattern, such as grid, lines, or triangles, and how to adjust the infill density, which controls the percentage of the interior that is filled.
Next, I'll explain the advanced settings, including infill layer thickness, which lets you adjust the thickness of the infill layers independently of the outer walls, and infill orientation, which can affect the print's strength in different directions.
Finally, I'll share some tips on how to choose the right infill settings for your specific 3D print, depending on its shape, size, and function. By the end of this video, you'll be able to confidently tweak Ultimaker Cura's infill settings to achieve the best possible results for your 3D prints.

Dude i impulsively bought a 3d printer and all your videos have been a lifesaver

[@ItsMeaDMaDe]

HA HA! Welcome to the hobby! i'm glad i could help you out. Best of luck

[@LAKXx]

@@ItsMeaDMaDe 2 months later and i am looking at 30kg of tpu pla petg and abs on a custom made damping table. This hobby really took me by the balls

[@StudioCreations]

This is a "must watch" video for newbies. They have so many problems with infill in the beginning of their 3D printing journey and you quickly and concisely give the info they need. For me, the INFILL LINE MULPTIPLIER info is exactly what I was looking for. Thank you so much. (thumbs up!)

[@WarrenPenner]

Great tips that'll doubtless save hours of printing time and tons of wasted filament. Thanks so much, Chris!

[@ItsMeaDMaDe]

That’s my goal saving you filament and time. 😁

[@DavidThomas-ke7ih]

Have been looking around for decent and clear instructional procedures on using cura and starting up 3d printing for 1st time, and well so far you have nailed it so you have picked up another sub. Congrats to an excellent tutorial series

[@ItsMeaDMaDe]

Wow thanks. I’m glad I could meet expectations! I’m glad your liking the series. Im still in the middle of it. There are still 4 or 5 more videos coming out over the next few weeks.

[@badatgames4127]

Was wondering why the views were so low on this tip video, it's relatively new. Good content.

[@ItsMeaDMaDe]

Thanks so much. Hopefully it will reach more people 😅. If not it at least helped the few that have seen it.

[@badatgames4127]

@@ItsMeaDMaDe I only started printing a few months ago, and painting just a couple of weeks ago, so it's always helpful to see these kinds of videos in case there's additional tricks squirreled away in them. While printing is a time-consuming and aggravating pasttime, when it produces results, they're usually great. I look forward to maybe doing some minis of my own in the future.

[@ItsMeaDMaDe]

@@badatgames4127 Ha I can't agree more about the time-consuming and aggravating pasttime. If you just started painting I have quite a few tutorials but in my playlists i have a beginner series on painting 3D prints that might help you!

[@badatgames4127]

@@ItsMeaDMaDe That one's next on my watch list, for sure. Thanks for the content, have a sub.

Any time! Hope it helped!

[@andyb7754]

Love the information but I feel I'm way too old to remember all this (will have to watch all of your informative videos over and over to get it to sink in. I'll probably be dead before that!! LOL! I send all the people I meet that's just gtting started in 3D printing to your channel because of the excellent information and how you present it. Thank you.

[@ItsMeaDMaDe]

Wow. Thank you so much for the comment. I’m truly happy to hear I’m able to help you and break it down for you. I appreciate the referrals as well. 😁

[@Cferg]

I enjoy these. Thank you for making it so simple. Do you do Blender or 3D Builder?

[@ItsMeaDMaDe]

Glad your liking them. It’s taken a lot of testing to break it down to make it easy to understand. Ive messed with blender but I’m not great at it. Never touched 3D builder.

[@paulsanguinetti2905]

This is a great tutorial series and has helped me overcome problems with my extruder. I've done the extruder calibration, temperature tree, flow calibration, bed leveling, and a few cube tests. I'm wondering since the results of these tests were incorporated into the slice on subsequent test, is there a particular order they should have been run? I expect the test results from ealier effect those of later tests, but should I go back and rerun them (in a particular order) to fine tune the results? I have to believe that had I run the flow test before the temperature test I would have had different results.

[@Digital_Jedi]

Let's go!!!! 💯🤘🤙👍

[@ItsMeaDMaDe]

😁

[@greatmarin673]

Thanks for this most impartant information. Could you let me know if a model using honeycomb structure, is infill density matters and consider in percentence ?

[@IrocZIV]

Super good video. Lots of info I didn't know. One question, Isn't infill area just dealing with XY, hence the mm^2? I think it would mm^3 if it was considering Z, and would be volume.

[@ImaNoobatStuffs]

yea i think he forgot that squared (^2) is different than cubed (^3)

[@stevekutny9695]

Good job Chris, thank you for your great work. I am using 5.3.1 and in the infill I cannot find connect infill lines, what am I missing?

[@peaceorpieces8343]

Great video with fantastic tips. However the problem i have is my nozzle always grinds/scrapes on the infill when going over 30%. The z offset is perfect and the nozzle does not scrape on the walls or top and bottom layers only on the infill. Please could you help with this? I have enabled z hop, stripped assembled printer, reset slicer, checked extrusion and it still drags on the infill. There is a short video on my channel of the scraping in action

[@jaysoncummins8197]

CHEP showed me a while ago to lower it, but add infill multiplier to strengthen and also save time

[@markgoode6268]

Hey bud, do you do a 2 colour print instruction for cure / creality>

[@jimmybaggz5932]

Is it possible to have different infill settings for different parts of a print? I have a week point id like to strengthen. Thanks

[@aakashiyer4885]

for infill line distance, does cura calculate distance from the center of the line or from the edge? If i have an infill line 0.5mm thick and i set distance to 2mm then will the distance be calculated from the center of the line or from the edge of the line?

[@mohammedsalem3657]

how can you change the infill angle from 45 or 90 to 10 degree (for the lines pattern)?

[@darrell271]

I have a rather flat model with areas I want solid. I've tried several infill settings and none of them cap off the final layers. Lightning was the worst. Suggestions?

[@Sincharei]

im trying to set the infill offset for x and y axis, but it doesnt show up, even when selected from the setting list naither print setting or model setting. 😢

[@airsubzero]

What I got: Lighting: Creating lighting pattern that gives top layers enough structure to print over it, perfect for prototyping Lighting: Creating lighting pattern that gives top layers enough structure to print over it, perfect for prototyping . Connecting Infill Line Setting: continuous infill line, adds a bit strength and stability. Infill Line Direction Setting: adds strength or flexibility to a certain direction. Infill Offset Setting: changing center of infill is useful in low-density print. Infill Line Multiplier Setting: increasing the no of infill lines, huge boost for strength in expense of time & filament. - Connect Infill Polygons : saves times while using Multipliers. Extra Infill Wall Count Setting: creates an extra infill wall for the next layer same as wall but printed as infill. Infill Overlap Percentage Setting: alternate to extra wall. How much Infill overlaps with walls. Gradual Infill: works as an interface for the top layers to save Time & Print and ensure top layers printed perfectly. Gradual Infill Steps Height: Distance from top layers to the first infill density step. Infill Before Walls: great for model that have inner over-hangs. Minimum Infill Area : awesome setting that prints small area as sold to make it a lot stronger Infill Supports: creates infill only in the only areas that needs infill.

[@Reds3DPrinting]

Yo bro can you update the connect infill polygons part of the video at about 29:43 i think cura removed that setting i cannot find it. Or if i am wrong can you lead me in the direction to finding it?

[@kailecross2391]

My infill is gone and replaced with a inner orange shell, how can I change it back?

[@user-nd3uc4ul4l]

I have a problem with my anycubic kobra max not printing over infills on the top and not smooth print on the bottom of the area where the tree support connects. I know this is wordy but I've been trying to figure this out

[@user-nd3uc4ul4l]

Can anyone help me

[@radhabbit4784]

do you cut the video every time you slice or is it just that fast haha cause i want mine to slice like that haha

[@stuartblock8582]

When building an airplane , does each part get sliced?

[@ronlan1984]

Cura won't let me change infill settings. What am I missing

[@iaincampbell4422]

Suspect there may be times that high percentage infill is stronger than 100% as helps transmit force through the part. But nit picking

[@scottsound4711]

Kip = DangIt

[@petejansen8098]

You are a guru on unfill. But the travel on my infill is stupid waist of time. I can send you my Cura slicer file if you want to try to figure it out. PLEASE. It wouldn't reduce the print time without the extra travel a huge amount

[@douglass69]

Is it just me or does anyone else not feel comfortable with Cura not saving Print Settings without an account, where they want to be able to use your projects and change your products....ANYONE!

[@hentaimonster]

Tutorials are great, but I really want to shave your face. Less face screen time, more project screen time please.
