Must Have 3D Printing Tips and Tricks! Episode 1 - Design Stage

[@unrealed]

I think "Replacing STL by 3MF" is worth it's own video. You could make a better case for potential current and future uses of the format. But most importantly, it will help the message spread better and it's pretty important that that message gets spread as much as possible. Also, from now on if you ever mention "the STL file" in a video, also mention 3MF (and maybe that 3MF is better. Gotta repeat the message so people get it)

[@cupbowlspoonforkknif]

Well at least it's the same number of syllables or else it would never catch on.

[@DarrenC_1024]

by comparing an ASCII file size to a Binary file's, yeah, I guess it's best to end the series here. If his point of comparison is ASCII size vs Binary size, that'd be a valid point, as in how to save space when saving model files.

[@albertvillalobos1377]

Angus, I appreciate your approach to 3d printing. It’s so annoying when others insist on keeping it in the realm of toys

[@joepie221]

Greetings. you have presented some good points here, but I'd like to add a few. I ran the 3-D modeling lab at Sulzer Orthopedics for many years and have a lot of experience here. I hate lists, but they sometimes help. So forgive me. 1. If geometric accuracy is more important that cosmetic, position your part to allow the machine to assist you. If the layer thickness exceeds your desired accuracy for a hole or round, don't lay it down for printing. There is a very good chance your machine will print cylinders and rounds better positioned vertically. 2. Strength, Lets use a roll of dimes for this example. It can be easily displaced/cracked if standing vertically, but if it were printed horizontally, each laminate layer has much greater strength due to the cross section. 3. STL stands for 'Standard Template Library'. It simply implies that the model geometry has been broken down into triangles. A digital approach that I have to believe most printer files use. When converting any digital model to an .STL file, you are give a resolution option and can reduce the massive file size if the triangles and resolution are bigger. 4. Clearance. I like the fit gage you made. Very nice. On certain laser machines, ( may be applicable to nozzle size) beam offset and diameter are available. you can use these values to lie to your machine and have it adjust your model size accordingly. The push/pull option you show is simply a nozzle/cutter comp like G code offset for CNC, just made simple. Thanks. I enjoy your presentations and video composition.

[@welbot]

+1 for clearance parameters! Always do this, especially when I release my fusion files for others to use :) Also 3d builder! It's my final step for confirming that files are error free before release! I will say though, with the 3MF file format, you do need to be careful, especially if you repair your model in 3d builder, as it will also store the original non-printable model in the same file, and you could inadvertently end up printing that if you're not careful. To check it, you need to ungroup and or unhide stuff using the controls on the right side, and you will be able to see if there's any other parts stored in the file.

[@tdumnxy]

As someone who is new to 3D printing but ready to move on from the 'basics' tutorials, I found this tips round up very useful. More content like this please.

[@kendallemory8455]

I also suggest starting with a very rough pencil sketch with your dimensions drawn on. The sketch doesn't have to be accurate but it really speeds up the modeling process when you have the rough shape somewhere other than your head.

[@thomasheisler]

3mf, I never heard of that before, I will have to look into it, thanks

[@Dust599]

Created by committee of rich companies... just say no.

[@0LoneTech]

The comparison was intentionally unfair; why use ascii stl instead of binary? Based on that the 3MF should have been uncompressed. Also, there are others like AMF and glTF. STL is lowest common denominator, like PNM.. or indeed ASCII.

[@derekchamberlain545]

Like you I use Fusion 360 to draw all of my 3D projects. Your final tip was to use .3MF as the preferred format for transferring files to various slicing engines but as many of your fans will be aware .3MF is not easy to find as a format on Fusion 360. I found the app in the Autocad store, downloaded it but have no idea as to how to use it to save files. The Autocad site is next to useless when it comes to advice for laymen using their products and your latest video has left many of us hanging. Please help me and I am sure many others out and explain how to save .3MF files in Fusion 360 so we can all progress to the future of 3D printing!!

[@nickosnachos6624]

love your channle! thanks to you and joel (from ed printing nerd) i am about to buy my first 3d printer!

[@blackredroll]

Tip 2: Use clearances but as early as possible if design depends on that. Incorporate clearances in sketches and/or e.g. extrud distance/offset

[@RyanKhoo]

Awesome work Angus, great tips that haven’t really been spammed across the internet before, thanks, look forward to the next one!

[@keeperofthekeys84]

Just a note on the Microsoft 3d builder tip: it is really convenient and free, but it also will crash and freeze, or just sit there and do nothing, if your model happens to be really big or have a large number of triangles. It can help to simply and remove faces in something like meshlab first, and then 3d builder becomes perfectly viable to repair models. It's actually a known bug with the program that it can't handle larger triangle counts, but for free software, it's not all that surprising, just good to know before you wait for hours for it to repair something, when actually it's just crashed.

[@AdrianMagni]

One thing it took me a while to figure out is that if you minimise the window, 3d builder will pause whatever it's doing. So if you start repairing a model and it's taking a long time you can switch windows and leave it in the background but don't minimise it!

[@luckysolve]

This series is just what I needed, and right as i pulled my printer out of storage too!

[@droko9]

You should have compared against a binary STL instead of an ASCII one, that would have been a more accurate comparison in file size

[@Arterexius]

Can confirm on making sure you have something to measure with next to you when doing CAD. It helps a ton. I always keep a measuring tape close and a caliper in the drawer. I'm planning to get a digital caliper soon, to make it easier to perfectly replicate existing parts and hopefully get rid of a lot of the trial and error phase

[@KieranShort]

The sectional analysis was something I knew, but forgot about. Always get in a hurry and forget to cross check the build-ability within the design phase. Thanks for the reminder! That .3MF format is going to help with an Abe Lincoln bust from the Smithsonian I was having trouble with. It has a huge number of polygons that just make it unprintable on my little machine. I dumbed down the mesh a lot but felt I lost some details in the process.

[@tristunalekzander5608]

Cura has an expansion offset that seems to work great (I used it for the first time yesterday). This is by far the better way to go, say, in CAD, you have a part with two holes, shrinking the object will solve the expansion problem, but now your holes are closer together. So it's better to make everything as precise as possible in CAD, but then tweak the expansion offset for the entire print.

[@Inventorsquare]

I take my calipers and zoom out my model to see it at its appropriate size on the screen for my reality check. I’ll start using.3mf, I never knew.

I ran into the "tiny" problem just yesterday. I added blind screw mount holes to the back of a known-good safety razor bracket. Eyeballed it in CAD, printed out. Holes came out tiny, took #4 flatheads-not something everyone has lying around. Gotta re-do with bigger holes before I upload to Thingiverse.

That rubiks cube core piece can be printed if you rotated 2 of the axes 45 degrees so it sits on three of the arms rather than 1. Then every part would print at 45 degree angles rather than 0 or 90.

[@GertGybels]

1:30 even harder when you are also designing for SLA and FDM. There I can see details of .1 very easely and on FDM they vanish. So I have to keep that constantly in mind when I switch between projects that have a specific purpose of print target. (Not to mention where to place a campher to aid with bridging, sagging of holes or easy support when FDM/SLA)

The STL filesize thing is a little bit dishonest... A quick look through my 3d models folder didn't find a single ASCII STL file - they're all the (much more compact) binary format. Obviously the other benefits (colour data, compression etc) are still real.

[@hanelyp1]

Some of the software I use to produce geometry only produces ASCII STL. But the software I use to verify the results (meshlab) can produce ASCII or binary STL, and I favor the latter.

Is it possible to use a ruler in cross-sectional analysis? I was trying to measure an internal dimenssion in cross section and couldn't find any way to do so

[@belladonnaRoot]

*cringes at press-pull* As an engineer, I've had several issues caused by past people press-pulling a feature, and then modeling over it later, or not using a sensible value. I'm not saying it can't be done, or that it always causes issues; just that it can create an unintended pitfall for your future self. It's probably more of an issue in AutoCAD and older CAD systems, but I'd say that best-practice probably is to factor in the clearance other ways. My preferred method (if your CAD supports it) is to set the main extrusion at say "10mm - Clearance", or pattern it at "10mm + Clearance" spacing. I've found that my printer undersizes interior holes but prints outer surfaces accurately. So a washer would have an accurate +-.05mm OD (minus whatever first layer artifacts), but a 0.3mm undersized ID.

[@dadsfriendlyrobotcompany]

Also, 3D builder is an excellent tool for checking alignment of objects before you print them if you are customizing someone else's design or adding a part to it. The measure function is fantastic for reverse engineering parts where you only have an STL

[@aaronramly1705]

TIPS FOR BETTER PRINT - print everything in vase mode in s3d. it will be 3x more accurate than with normal printing. you can even see the polygon on the printed model. try a calibration cube in vase mode vs regular print with infill. the printer itself act differently. it will be quieter than normal. no more shaking,no ghosting & ringing. the corner will be sharper. no matter your resolution the top layer must be 0.5mm height. if u are printing 0.12,top layer must be 5. dont believe me. TRY IT ! note on some print, u may need to readjust extrusion multiplier higher than normal.

[@NiyaKouya]

Sorry for nitpicking, but @1:19 6,977mm is NOT 6mm... That's not how rounding works :P

[@JeffDM]

It would have been nice if you mention the size of the binary STL for the same file, since that's an option in a lot of software. Unfortunately my CAD doesn't export 3MF yet and file size really isn't a huge problem for me.

The only thing you have to watch is when sharing 3mf files online. They can contain meta data (depending on how you made them) which can pose a privacy concern. That's why I still only upload/share stls

Binary STL is much smaller than typical ASCII STL. So it needs to be included for a fair comparison. On the other hand, STL stores each vertex repeated for each face, so an indexed vertex format might save substantial file space.

Would love to see some projects and Tutorials how to go from a 3D scan, clean it up with mesh mixer while retaining resolution and critical geometry, and making it compatible to work with add and modify in f360 utilizing and converting to quads and brep so scams can be modified like a parametric solid.

Clearance = -0.3 mm is wrong approach! I would prefer to have clear parameter equal to 0.6 mm and then to use in the design "-clearance/2". In this case "clearance" will have physical meaning as distance between cubes. If later some other objects will be added with some other approach to add distance between them, "clearance" parameter could be used over and over again without surprise that it is negative and actually half of required clearance!

[@brynyard]

Well, an obj and stl is a very simple txt file with one line for each point and vertex index, its very trivial to parse and can easily be done sequentially without loading the entire file. A 3MF file on the other hand, is a zipped XML file that can have a dynamic structure for both vertex format and position format, so not only do you have to load the entire file first to decompress it (to a significantly larger file than both obj and stl), but you have to parse the xml structure (did I mention it is dynamic?). So from a software developers standpoint it is just a complete nightmare in comparison, the only reason a loader would be able to run faster on a 3mf file would be because the obj loader is really bad. Why they've created this format is beyond my comprehension, it is utterly useless for large files, and there's lots of better formats if you need the extensibility. I suspect this happened: xkcd.com/927/
