- In my recent 3D Printer build I employed a lot of tricks to avoid support material!
While they can be extremely useful, enabling support increase print time, material use and clean up for 3D Prints. Using these design tweaks you can avoid the need for it altogether.

'Designing complicated models using separate components and groups' should be the next topic, mostly so you would start using them as well. They save quite a lot of time when you make and edit larger designs consisting of multiple separate parts.
Is possible to move steps in timeline to and from group without cancelling the group already?
@Daniel Jack definitely, have been watching on InstaFlixxer for since december myself :)
@Daniel Jack Yup, I've been using instaflixxer for since december myself =)
@Daniel Jack Yea, have been watching on InstaFlixxer for years myself :)

The multipart and self-designed supports was something I've been using, but those sacrificial bridges! Genius! So obvious now I see, just never thought of it! Brilliant!
Angus, i have been designing my models like this for years, but its good to see it being acknowledge more
Awesome! I suspect a lot of these tips and more are a little like convergent evolution - designers face the same hurdles and overcome them in similar ways. Back in the day we didn't have this new fanged 'support generation' tool in slicers! :)
Maker's Muse not only that, I just hated removing support material is a pain to remove if your using PETG
Sacrificial bridging and manually designed-in supports were very much a thing in the "i2 Prusa Mendel" days, if not earlier.
@@JeffDM I haven't seen any of these techniques in any thingiverse model so far. Or perhaps I haven't downloaded enough of them. lol
Too often we have to fix the thingiverse models ourselves anyway....
I love the rain, especially Australian rain because for it is falling ground to sky because I am in the Northern hemisphere 💝
Huuuh???
I just wanted to say thank you. Your videos have helped me figure out ways to design parts around printing limitations, and has allowed me to take on much more daunting tasks.
Thank you so much. I was making a design where I was thinking I was going to have to make it in two parts and connect them together but hated the idea so I was waiting until inspiration struck. And putting in a temporary support that allowed a bridge was the perfect answer. Awesome. Thanks
This video is pure gold! You made an oblique reference to this video in your "ELITES don't want you to know" video, and I had to find it to see how you design out the need for supports. I still need to go into Fusion 360 and try creating the sacrificial bridging, but I have saved this video in my favorites so I can always go back to it. Every once in a while you come across videos that stand out as exceptional, and this is one of them. Thank you!
I am designing Parts for my 3D printers for over 5 years now. In this video I really learned something new! Thank you!
Again, what awesome content! You're clearly back at it even better than before since your well deserved break. Keep it up Angus!
Angus! I love that you are covering this topic. My work with resin printing and adding manual support with various orientations to minimize supports has been definitely a learning experience in developing an “eye”. It’s not something that comes naturally.
Creating my own supports was something I learned from you a long time ago & it's worked every time. It does take some thinking of "how do I want this to work" Great tutorial as always.
I have been designing 3D printable parts for a few years. I already knew all the tricks you mentioned, but I still appreciate your videos.
You are the best teacher about 3d printing, I have ever seen on youtube. Thanx Man.
Thanks for the bridging tip. I tried it today, and it really makes a difference to printing with supports.
Nice! This is exactly what I needed today; I recently bought a small printer and I was just this morning thinking about supports, material use, multiple parts, etc, and this really cleared things up and set me in the right direction. Thanks much, you're awesome!
I've broke things down sometimes to print better but this really highlights a lot of great design tips. Can't wait for the next video.
Have used the sacrificial bridging technique in a model today and it works brilliantly. Also used the 0.3mm super fast method you explain in another video. Many thanks!
Excellent video. Definitely could have used that tip about the sacrificial bridge in the past. Thank you for your high quality tutorials!
As I'm working on a huge engineering class project with a majority of the parts 3d printed and having just bought an ender 3 i really needed this
Fantastic video series Angus! This and the hole design video are all great advice.
I actually used this technique when designing my first Benchy. After hollowing the cabin I was left with a other large unsupported ceiling. I added ceiling beams inside the cab on the under-surface of the ceiling. They did not print very we'll, but the resulting mess of an attempt ended up supporting the ceiling of the boat cabin. Glad my first hair-brained design attempt is actually confirmed by watching your video. Thank you!
Good video as per usual matey. Me personally, I’m not fussed about producing models and items all in one piece, I’d sooner split things rather than faff and waste time on something that may not work, and maybe look poo. On a side note, I appreciate all the hard work you put in to these videos, Angus. Yours is the only 3D printing channel I watch, as your content covers pretty much everything and you have a unique way of getting your point across. Keep rocking dude, you’re doing a great job with it all. Cheers, Lee (UK)
Really useful, thanks! I can't believe I've been printing for a year now, and a couple of tbese ideas are new to me!
Good information! Started using bridging very recently after having a part turn out poorly. I was to the point of trying anything. I still need to tweak my settings for bridging but it was definitely the answer. I wish I’d seen or thought of this earlier. Keep up the videos. So much helpful info.
never heard of sacrificial bridging. great idea. thank you!!
Great job Angus, really. I remember one of yours videos saying "i don´t want make "beta tester" and lost my time, i don´t want to be a reviewer. I want to help de 3d comunity" (or something like that) well.... you really make it.
Thanks!!!!
Thankyou Angus! Your last two videos have taught me so much about optimising print performance/quality! I never would've figured these techniques out, especially the cylindrical holes with expansion gaps, I can't tell you how many PLA holes I've had to drill/ream out to get that perfect bearing fit! :-D Really appreciate your content.
Great video as always! I picked up a few tips for sure
I'm loving this series! Can you do a video on splitting a model, specifically .STL files, and adding tabs/pins and holes for joining them post pint.
Great video! I am just getting back to 3d Printing again -- and Definitely some tips I'll be using! Thank you!!
now this is what im talking about, great job!
I was thinking of designing my own as well and now I know its possible this particular way. great job!!!
Another great video! Will definitely be implementing these into my future designs
You can also "split" certain overhanging parts to be completely separate, and then add an assembly feature like a groove/tongue or an interlock for adhesive fixturing.
My little Markforged Onyx one machine has a small print volume, and I find myself splitting parts into 2, 3,4,5, or 6 sections and doing cluster prints to save time.
Thanks for another very well thought out and informative video.
Perfect video. Even better than the hole design last time.
Great video as always. Thanks for your shared information. Still my No.1 3D printing channel.
I could not hear the rain at l.
Enjoy it and rejoice.
We in Cape Town South Africa are facing our second year of a majour drought. We are thankfull for every drop when it rains.
Thanks for the kind words! We have just started to come out of a fairly major drought here and hope you see more rain soon.
Looking forward to trying out the sacrificial bridging. Another great video Angus!
As a huge fan of ALL the Fallout series - I applaud you and admire your ingenuity. Well Done! (insert Vault Boy Thumbs Up HERE!)
Love your work, as always great to watch and learn! Bang on, less is more with great quality like this who cares for pushing x vids per week/month. Totally on the right track mate, keep up the amazing work!
It is raining here in Ca. USA also. The hard part about your videos is remembering ALL the good info. Thanks. 🖖🔥⌛️
Sometimes it might be possible to join two parts without bolts using similar principle to lego blocks. Square holes and matched square pins. Interesting video! Thankyou for sharing.
Nicely explained as always. Although this little project of yours has got me rethinking the printer I was designing...
One of your best Videos Ang, will try to put this into practice at the weekend..
Like your meshmixer videos, this series has been super helpful for me. great content. thanks
These design tips are gold 😃 much appreciated !
These are great techniques. I’m totally going to apply these!
Cool video. You are one of the reasons I got my ender 3 and these kind of videos kind of motivate me to make a costume printer myself
Good tips, I have sort of started to do this with my designs making separate parts part anyways. The built-in support thing I will have to try on my current design but I think I can fix it with just putting some chamfers in the problem areas. They are not going to be visible to anyone so I think that would be ok. But I have been looking at trying to minimize the need for support material as much as possible over the last few projects. and your tips will help for sure, never thought of making my own supports, clever.
Thanks for more tips and trick on cad design. 3D printing is like any other manufacturing process, with some things they can and can't do. Know process limitation and how to bypass it is far more interesting than just download and print. Some more tips you can take a look on: You can create parameters in fusion360 with extrusion width and layer height and use it in some critical dimensions (home made support structure for example, or to be sure that you have at least x complete perimeter around an hole), printing direction have some influence to design strength. Best regards,
no sounds of the rain that I could hear.Nice video curious to see the end results of this printerLove your videos as always glad your back from break
hope you recharged
Thanks Angus... these are things I'll definitely consider next time when designing something. I've got a an i3 mk3 MM2 on order, and now have some PVA, so was thinking of using soluble support interfaces in the future where needed. But this might be easier.
thank's a lot for our teardrop shaped holes tip !!!!!!! i used it in my job and spread it to my collegues an boss. Even if I said that it's your invention but I got felicitations so I give you felicitations back !! ;)
Awesome! Thanks for watching :)
Maker's Muse i used it on a markforged tow and i Will try asap on most standard printer
Hey Angus. Great Vid as usual.
We use Brass inserts instead of nuts. No slots necessary. Just design in the appropriate sized hole and then heat / melt them in with a soldering iron. Once in they ain't gonna come out. And they're cheap.
Good tips; I did the same things, but there is one I missed:
I have some prints, where I drew the object in a 30 or 45 degree angle, from the bed.
So I added some smal support construction at the bottom, which also
helped to add surface area. One more thing: These nut inserts...
People tend to design an opening next to the screw hole, but you could
scew it a bit, so that the opening is offset in relation to the crew hole.
I use all of these in my models. I tend to use polygonal shapes if I need to index parts together as they tend to print better than circular indexes and these have allowed me to make parts that exceed the build volume using the least amount of support material.
Great tips. If you ever get to the Netherlands to give a workshop on 3D printing, I certainly would attend it! Keep going Angus.
Impressive, very good designs, wow
Thanks for sharing 😀👍
That is great job, mate. Keep on. Hi from Istanbul.
I love this series!
Thanks, Angus, for the tips!
genius in simplicity.
Thankyou for all your hard work! The information you provide is just great! I've learned so much from your videos. Please consider doing one on bridging for people who know nothing about it. Please please please. And thanks again!
Very clever Angus!
Awesome tips, thank you.
Holy crap just about to hit 1M subs! Congratulations on the major accomplishment.
many thanks, great ideas.
Thanks Angus, another great video.
Very good video. Helped me a lot
Great tips. It would be wonderful if you could make a video about printing multiple part components but without the need for screws and glue. How to design joints that just fit together and will work for different types of things. I see so many designs with screws that just would not need them. Love your vids!
Angus thanks for doing this. I'm struggling with design that has a lot of helix curves. Tried building supports horizontally, but I think I should build them vertically or try no supports what so ever.
Great tips on these video series. Thanks for sharing. : )
Very useful tips and solutions
I too had to design a two piece hotend carriage. It had to mount an E3D v6, 2 noctua fans for cooling the part and E3D, a direct extruder, and also be able to support a cable chain so all the wires don't go down into the printing area. I used gussets and thick walls so I could tap threads into the screw holes.
That Vault tech printer is so cool 👌🏻
Great tips, started modeling myself and didn’t yet realize I could totally design it like that. Haha Only thing that has to be said, all of these things do require a well tuned printer ofcourse.
Huh, I had no idea you could actually print over open air like that in the sacrificial bridging bit. Obviously something that's either floating or attached on only one point is impossible, but I didn't think you could even really do it across two points like that since the filament doesn't have anything to adhere to as it goes and it'd just sag. I guess the cooling fan really does good enough of a job for that beyond the first layer droop? Thanks for this series by the way, I have my first 3D printer coming in a week or two and I haven't touched cad since Solidworks in high school and this has been a perfect refresher. Detailed but concise and efficient, just what I needed to de-rust the memories while also understanding the new software and modern parametric style
Thank you for this video. People want to print everything in one go FAR to much. There are reasons that manufacturers make things in more than one part other than production technology. Too often I hear "they don't because they can't." I call BS on that. Why do some people think we have manufacturing technology that Toyota, Ford, GM, Bowing, GE, and EVERY OTHER manufacturer on the planet does not? There are cost, speed of production, reliability, assembly, repair, maintenance, environmental, and material type reasons behind the decision. I probably missed a few reasons, but these are key. I was taught to design the part on paper to work correctly first, then choose the material that is best suited, THEN change that material for the one that is best suited with cost in mind, THEN choose the best production process, THEN AND ONLY THEN do you go to CAD. People in 3D printing are pigeonholed into a few materials so they usually skip that step. I don't think most people realize how limited 3D printing can be. It has such amazing potential that to often the down side gets over looked. Thank you for setting things straight. Also couldn't hear rain...
Hi Angus, amazing tip here, loved it, as I often design parts that are sort of inverted staircase shape of thing. However, I've run into an issue, with longer pars having the infill pattern aligned with the perimeter. I'm using Slic3r prusa, and I've noticied that on the 1st layer, the infill pattern always sort-of bridges between shortest distance, but with latter layers it's not the case. Would be very grateful for an advice. Cheers
Great food for thought.
Is this printer that you printer out available on thingiverse?
I've been learning things lie this to some extent. I remember years ago 3D printer users (local anyhow) being like "some things won't print well", and now I'm like "things *designed* to print well do*. It's not a technology that does magic, it has to be skilfully used. :)
PS I used your teardrop hole solution in a build recently! :D
What do you think of Panamount PLA filament? I bought the British racing green specifically. BTW I bought my first 3d printer today, the CR10!!!
Thanks Angus, great content as always. Cheers, JAYTEE
Great tips Angus. Couldn't hear the rain at all.
Wow! Top notch content and building on the previous release. I've tried the sacrificial bridge for holes and am pleased with the result. Looking forward to integrating some of the othe suggestions. Are there circumstances where a dual head extruder with soluble support material has a clear advantage?
I made a ring to join two pieces together, and for that, I found the support material extremely difficult to remove, but I heard about sacrificial bridging 3DPN's video, and I ended up designing in some posts on the outside and inside of the ring to bridge to those so I could print it without support material. They actually broke up pretty well, though I did end up cleaning them up with a knife.
Thank you for the tips! Extremely valuable for a newbie in 3D modeling and printing! Are you still planning on making a next video in this series?
this is brilliant !!!
Thanks for these tips; they are great. I will start using them.
May I offer one of my own? Use threaded inserts instead of captive nuts. It's better for all parties.
Your last video helped me out on some M2 screw holes (ignoring that I measured them wrong... Should have been M3...). And I have been trying to apply this when I can. Still need to learn how to split existing models, but am doing it on my own designs at least!
Hi Angus. I think it's a good idea to generate a test piece for the "hole support" bridging rather than get into a long print ( like your base) only to find out halfway your bridging settings need more work. The Nema stepper feature you showed, with it central large and 4 bolts holes, would be a good example.
Nice video Angus, since you started to optimize your design for non-support style (which is the right thing to do), you may start thinking about removing infill where it is possible because it's importance is overestimated.
Used to do this with Meshmixer I think. But use Sketchup more often than not as I work mostly in straight lines...haha. and it is dead simple to use for quick prototyping.
I had never really taken the extra time to throw supports in though and usually let repetierHost/Cura just do it's thing - Which is really annoying when you have Holes on the X plane that Cura might orient in a way that is easy to remove. But any openings you have then in the Y axis it basically Fills in! So I used the later method on the weekend - in a 60mm wide by 15mm opening I placed half a dozen 0.6mm wide/thick posts that printed with No walls, very little material, was sufficient to hold up the 60mm space at the top of the opening, but was Dead simple to remove.
Wish I could post a pic - because the resulting "lattice" looks good too, due to stringing between the posts due to no retraction...
What you could also do is set the overland needed to print supports to 90 degrees so that it won't mess with holes or curves and won't droop the overhangs
Hi Angus, What filament did you use for the hot-end part? Cheers.
Interesting video, was wondering if you could let us know the pros and cons of small diameter nozzles. As I switched from 0.4 to 0.3 and been having issues with simplyf3d settings. Would appreciate your in sight.
Nope, didn't hear the rain at all on my monitors. But those are all good idea's on how to avoid support materials, I'll keep it in the back of my mind as I start to get into modeling.
Yeah noise gate did a WAY better job than expected :)
Angus, maybe in 7:36 you should choose bridge settings to a perpenticular angle... this should make a better bridge for that part, less cleaning and more precision/ less falling layers on that @maker’s muse
Thanks for the desing tips, awesome stuffs in your channel.. I watch it for a loong time, since the beggining. Cheers!
@maker’smuse
I'm nearly 60 I fall asleep to rain 😂 😂 new to 3d printing, actually teach it as an ad on, point my class to your videos, I'm honest enough to tell them I'm a chancer at this game still, but hopefully I'll get there soon, great simple ideas in this one
I just wanted to point out that in some slicers have to enable printing thin walls when printing built in supports. Good video just wanted to point that out. It may be that I used .4mm supports. In yours you mentioned larger
