Design Tips for Support Free 3D Printing Models (FDM)

Can 5° bridges work? Thanks :)

Is there a program similar to fusion 360 that is more priced toward a humble hobbyist and not at sky high professional prices?

Great video as always Angus! If you're looking for another topic in a similar space I have a suggestion! Design Tips for fast & efficient 3D Printing Models (FDM); Using less material or shapes/featured that go well with how the layers build up.

Thanks for your amazing content!

Maybe run a bridge for the overhangs, it's making a step on your test sample if you designed single thread behind then backstep and start the angle?

It is possible to print with an overhang of 60 degrees.
At least, with PETG, I was able to print a spring, with an overhang
of 65 degrees. I just needed to give it time to cool down,
so I printed a column on the side, which did not do anything, except
allowing the very small cross section of the spring, to cool down.
Sometimes, you might want to incorporate support material in the design itself.
I also noticed, Fusion360 can generate support.
And it looks like it's doing that pretty well, compared to other slicers.
If you have experience with this, let me know what you think about Fusion360

I have the mechanical/electrical side of 3d printers down now, but I thank you for your ideas, information, and input concerning the printing side of the equation. I get more hard, usable information from your channel than another other two channels combined.

Question. I have an FLSUN QQ-S and I replaced the nozzle and somehow adjusted the zed axis and now one side of the print is fine yet the other side has striation and poor print quality. I use Simplify 3d as the slicer. What could be wrong?

speak louder i printing wife 3 week still going going. soon she make coffe :)

So can you get further overhanging via a larger nozzle?

hello angus i just started whit 3d printing and i thingk i just got the hang of it but is is stil a little slow on my cr 10 s i saw your video of 5 cool things to print and the time it take s u to print it is 2 to 3 times faster then i do it could u pleas tel me your setting of your slicer i use ideamaker greets from holland

Has any manufacturer made nozzles with opening shapes? Ovals or rectangles. Over laying an oval shape and hardens faster could increase angles? Just a thought.

Thank you sir

I think 3d printer could print non-horizontal bridges, but I don't know any software which can generate needed gcode.

Was the single layer added to support the holes added in the slicing processor or was the part itself 3D modeled with an extremely thing layer of material there?

Another great tips video, thanks!

hello im still new to 3d printing, Currently i am printing costumes in tpu just wondering about using supports on tpu and looking for advice i have a small 220x220 x250 longer printer and a cr10 s4. also any tips for printing large items such as full torso piece on the cr10 s4 in tpu . i started to print a chest piece which said time was 3 days day one it was great then day 2 it went all wonky

really good information presented very well. congratulations for your channel!

I kinda want to know what will happen if you 3D printed in space

I designed a model that's 9 spheres inside one another with very minimum support and all spheres can rotate independently in all axis. And the idea here is that, for PLA at least, printing bottomless is very viable as long as the first layer layout size is large enough to make the model not tip

Can someone design a "chamfer support" add-on for cura?

I bought an creality ender 3 Pro last week and without touching any settings I got to 80 degrees.

have you ever tried mounting a 3d printer upside down and printing with out supports?

Thanks! A perfect video to ease my head; currently printing some parts that really ask a lot of FDM in general let alone my little limpy printer! (The Z axis bearing housings are cracking up: my only options are to either wait a month for replacements, or forcefully print some insane geometry [holes in X,Y and Z directions! W/ extra overhangs and slots!] and hope my printer handles making it's replacement parts...)
At least now I know how I can get through this with less headaches, and more serviceable parts!

Anything I print takes 15+ hours if I use supports my printer must be generally slower than most

What a coincidence. I was printing several different face masks to sell and lowered the perimeter to 1 to make the mask as thin and light weight as I could for comfortableness. The 1st layer height to .15, layer height to .2. extrusion width to .45 except for a couple individual ext widths that were .42 and .45. Well the print turned out very smooth except for when the layers started to angle and a few layers were all unraveled but then after that beautiful layers. I don't know what happened either I walked into the room and a gust of cool air from the AC must have reached the printer (corner of my room) and caused the plastic to cool. I keep my windows open for air circulation which (desert heat) and doesn't affect the plastic cooling. It was as if my Prusa Mk3 was saying i screwed up a few layers but got back on track and check it out. I couldn't believe how the layers regained their foundation and didn't become uneven post the messed up layers. That was the first time I had a print that had a hiccup but regained its footing and came out nice. I cannot use the print to sell even though I blow dried the print and was able to press the layers against the clean layers to make it somewhat decent. Anyhow, how I see how lowering layer height and increasing extruder width helped. I am going to see if I can code some gcode to slow the printer speed down for those messed up layers, because I have my speeds kicked up for fast print. And it could have been the extruder. Maybe there was a catch in the spool filament that may have slowed down the extruder of trying to extrude filament. I do not know until I exhaust my tweaks. Any suggestions would be helpful. Thanks again for the great video.

I dont like the LETS GET STARTED part

your videos are very informative thank you for the work you do.

Thanks Angus! It really helped me!!!

The world is a better place with people like you around. Thanks for sharing this super useful tips.

As a beginner I add automatic supports and brim to every printed model, unless it is said in a description, that the model is printed without supports. Did print one without supports, as it was said, and it worked. But if you have to tinker with slicer settings to avoid using supports, then you better not say 'no supports required' in the description of the model.

How do you deal with, the gravity affect the sizing? I use 45°for a long time, and noticed that the gravity still make messes with the shape, like make it curves, wrong angle, wrong cross X sizes, etc. otherwise, a lot of times when I need the side stiffness , the tilting would be limited. This time I use different material method, nylon is not stick good with pla, so when I make this type of support, it’s easier to remove.

Not always doable, but designing parts that won't require support is always my goal, once you get into the mind set it starts to become a more organic process.

Thank you Angus I am 59 and new to this 3d printing milarky and I have watched many of your videos they have always been enlightening and informative, I thank you for that. To me the hardest decision is when to and when not to use support material this video has helped me a lot you are indeed a 3d printing GURU once again many thanks.

Thanks

I ordered my Ender 3 v2 this week and I had design for additive manufacturing at university. It baffles me, how many things on thingiverse are obviously not designed with additive manufacturing in mind. Obviously most people cant cope with the idea of building up parts from nothing and stick to subtractive manufacturing when desinging stuff.

Hi, Im having issues printing a model which uses Boole - i connect and flatten the object in C4d , Cura sees the holes (windows in a building) , but the printer ignores the holes

ive got it print in space and you dont need suports

Man the background music sounds like my ringtone, thought someone was calling me all the time

Can i have the parameters to print?

280 k views but 7 k likes, thats unfair

My problem is that I want supports but the slicer (Cura) puts supports where they are not needed and though this is usually not a big issue it really bugs me.

Aww, you look like such a baby. Only 5 short years ago. You have really grown up bud!

Great info. Thanks!
