Where an inventor can go to request, specify, and pay for a unique 3D printed part. Just kidding---you didn't actually mention that, though it would be very, very helpful if you did. Cheers,

@@johnstrawb3521 I think it's called shapeways

@@johnstrawb3521 Are you looking for someone to design a new object? or do you want to 3D print an existing object? You can hire CAD designers on upWork.com or you can have prototypes made by Xometry.com

The hinge was my favorite. awesome video love the concept

Chain 🤯

Actually the video is just an advert for his fusion 360 course

I have been in that same situation for years. Only Tinkercad. Onshape is another alternative btw. That works even on my iPad, and I love it. BUT.. there is quite a treshold to transfer from Tinkercad… propably also for F360…. I have done it! And I am cheering you on! 😊 Still in love with Tinkercad btw 😊 It is SO simple and intuitive 🥰 (although limited) Oh.. btw #3: The youtuber "Teaching Tech" (who I like) has made a good set of videos where he teaches Onshape "from scratch".. (just in case 🙏) Watch his 5 min video "7 reasons why Onshape is the best…" to get a taste of him…

@@oljobo Good to know, I've been looking for something with more features than tinkercad

fusion 360 is flipping incredible.

I use the student version of F360 but I'm gonna learn blender soon, as a Linux user I really dislike having to boot into an external hd or run a VM just to 3D modeling, so it makes all sense break free of windows/mac specific software.

@@renatod.o.2930 I started learning Blender after years with F360. To me, if Fusion is drafting, then Blender is painting. There's just not enough precision for me. Blender is fun and you can achieve neat results - for me it's not a great tool for 3d printing.

Yes, like on a DVD case. That is just a print-in-place hinge...

haha that's why learning both is great. Each has its own pros/cons

How did you learn blender???? I'd have less trouble building falcon xix for musk than learning blender

Blender Guru has a 17 part playlist on KZfaq that explains the foundations of organic (non-CAD) 3D modeling. You can check it out.

SAME, I thought you had to pay for fusion 360?

OnShape is also a nice alternative, don't even need to download anything as it is cloud-hosted.

CURA 'per-part printer settings'. Divide your model into functional parts; each part is assigned different printer settings. The only 'catch' is needing to use the same layer height and hot-end temp for all parts of the model. It will print as a single model. Example: a long tube with end-closures printed as a single thing. Print it vertically: The first closure is printed in 'detailed mode, two perimeters with dense infill, on a raft, support everywhere, default thickness'. The tubular section is printed in 'vase mode, no infill, single perimeter, 0.7mm wall thickness'. The second closure is printed in detailed mode, two perimeters with dense infill, no support, default thickness' There are at least two ways to divide the model: 1) Cut it up in CAD, export each piece, load them into CURA, position the parts, assign print settings to each part. Tedious, but it works. 2) Load the complete model into CURA, then use the 'box selection tool' to assign print settings to each part of the model. A little less accurate, but a lot easier. CURA preview after slicing verifies the correct settings are applied in the right places.

Those kinds of settings will only be helpful if yo u use them yourself. Most people take only the stl from Printables/Thingiverse/Thangs and slice them themselves (because they have a different Slicer, Material, Printer, Nozzle Diameter, ...) and tricks like this will just automatically be picked up by any slicer without extra configuration.

Yes, this "expert tip" is really bad advise....

​@@emielessink3191 No it isn't, both methods have their place.

​@@andrewholdaway813Do i need to prove it scientific? 😂 Look up moment of inertia.

It's kind of true only for a sub section of cases. For example if your part is under simple compression or tension forces it doesn't matter where the material is, only matters how much material is in cross-sectional area. If the part is under bending then it is sort of true, but what you are referring is moment of inertia. Also center of gravity also is only half true, the moment of inertia is defined over geometric center (geometric center of a area not center of mass ). So the geometric center is in same location with center of gravity if the volume of the part is uniform density 3D prints may be uniform but mostly are not due to wall layering and infill etc. So having more perimeters doesn't always make things better, it does only in some cases. One kind of needs to understand how the forces are acting on part to make it stronger. There's also a difference between making part just stronger of making it stronger while retaining original weight.

@@koitk Don't forget buckling though

Exactly. With the pinhole, he's just basically trying to create more infill, but the problem is that it's only centralized, so unless you know exactly the stress load is exactly in that pinhole area, you are much better off with thicker shell, and/or simply more infill %

Wow! Hey Creative Mindstorms! Love your videos! ;)

@@danielsaenz5570 Hey Andrew! Thank you for commenting under this video and thank you for your kind message!

I generally don't watch these sort of top 5 videos because there's so much filler content in between each point. But this one got straight to it and I had the same thought after watching it. Super informative!

I actually doubt this. Because for bending stress the extra material at the center does not make a great difference. Thats why H-shaped bar is used alot in construction: it is much lighter than solid bar but hadle compareble load. Same here. If you want stronger part you need extra material at perimeters (extra perimeters) bot not in the center.

@@dmitrynuzhdin the tip is generalizable to being able to add additional strength and support (via perimeter generation vs infill) anywhere in a model. The youtube clip confused the issue by showing the support being add to the center of a cylinder, a place that typically doesn't need additional support, but the Voron Stealthburner uses this trick in it's design to add additional reinforcement/rigidity in key structural places.

How do you do that? I print the inner thread at 95% scale in X and Y direction (thead standing in Z direction) but the downside is that then the whole model gets scaled, not only the thread.

I also add a fillet to the thread edges. I find threads work better when that is done.

​@@Djeez2 use press/pull on every surface of the thread. When you make it on both, a normal screw and a nut will fit.

I often feel very restricted by Fusion 360. I wonder if Blender has this tool. Have you done threads on Blender? Is it better than in Fusion?

@@andreojuegosyestrategia1266 Onshape has a decent thread tool, better than Fusion, and there is a good Fusion plugin to do threads, but none of them are really full featured. Honestly what I have resorted to is downloading CAD files from McMaster-Carr with the threads I need and chopping them up for use in Fusion. I do not believe Blender or even Maya have built in tools to do true manufacturing style threads.

Blender have plugins for threads, I have heard it from more skilled person, who also used Blender. But I never used one. For nuts and bolts I use OpenSCAD customizer from thingeverse. And when I need threads, yes I would create one in openSCAD, then chop it in Blender = )) I tried Onshape, saw some videos about how it is easy to use and such. Actually I did not understand a thing there. And later they banned me, a month later, after I forgot that I registered there. So yeah. I prefer offline tools anyway. Just like in the old days, you know.

Why not

@@Bigsativa sloppy

On my P1S I can get away with 0.1-0.2mm tolerance easily. 0.4mm would feel noticeably loose.

You can export your solid bodies as mesh and then upload to slicer

@@combinacijus wow didn’t even notice. Thanks!

It depends. I do not know about stock printers. But custom heads have no trouble with retraction distance of 1mm or even less. I have not very good custom direct, which I 'temporary' using for two years, it handles 2mm with no trouble.

@@enosunim printing tree supports introduces underextrusion into the model. 3d printers ASSUME that 3d printing is linear. But flow pressure is not linear. So when the extruder moves linear, the filament at the nozzle doesnt. So the more you retract, the more damage is done to the print quality.

@@tazanteflight8670 there are different techniques to take into account pressure change like Linear/Pressure Advance. Also it really depends in what order what is printed(if supports printed before model layer or after it is just like normal retract on layer change). And heatblock chamber volume. It depends. I do not see much difference between tree supports or printing multiple objects at the same time. If retraction distance is short, then pressure change is also small.

I have the same question

They made the free version very restrictive and lost many customers because of that, FreeCAD and other CAD programs have gained a lot of new users in the process.

@@htpkey Fusion 360 was free for non-commercialuse. They changed the rules later on and made it more restrective at some point

@@tomaszworoch True. They still offer a free "stripped-down" version of the program. But I would rather use something else.

STL works fine in Fusion 360.

@@DisorderedArray Then I do not know why did I leave this program xD

I prefer FreeCAD for most things. For one, it's open source, for two it runs native in your comp. It is quite powerful, in fact it has some functionality that Fusion doesn't (and vice versa of course).

Yeah, I agree. Recent events show that not all cloud services are 'free'. They change their mind from time to time. Opensource never fails. It may be not optimal and have trouble. But at least it is permanent.

Thanks! We have free lessons as well on our tutorial channel: www.youtube.com/@3DPrinterAcademyTutorials

@@3DPrinterAcademy Thanks, I will check it out. I actually also just downloaded the lock print. Really cool.

Still free but as I get it they removed tons of stuff from the free version.

@@johnpekkala6941 they removed a few features like running simulations and generative (automated) design. That’s stuff most hobbyist users will never need and the free version of fusion still has more features than most of us will ever use.
