3D printing mysteries that need to be solved in 2024

this year is about to end but for me there's still too many loose ends here are the 3D printing Mysteries that we need to solve in [Music] [Music] 2024 normally at this time of year I make a Q&A video to celebrate the anniversary of the channel but this year it's different I have some questions of my own and I'd like your help in answering them some of these are serious some of these are not some of these are Technical and others just relate to the community they're all worth pondering so let's begin we're going to start with something that perplexes me whatever happened to non-planar 3D printing you may remember in 2019 I made this video let me give a brief recap regular 3D printing is just a series of XY movements stacked on top of each other as individual layers more like 2 and 1/2 D printing on shallow surfaces the stair stepping from this is quite obvious and what non-plan AR 3 printing offered was true threedimensional movement using x y and Zed all at the same time not only was this mesmerizing to watch but on shallow surfaces print quality was greatly improved with the layer line stair stepping 100% eliminated obviously this process suited some geometry more than others but the results were great so why hasn't it taken off well one problem is that most already printed don't really have the required clearance around the nozzle for these three-dimensional extrusions to take place without a collision in fact in that video I had to remove a bunch of parts to tidy up the print head and give the required clearance this is a hassle but it's also completely doable no doubt the community would find a way the other problem is that the software I tested was an experimental Fork of slick 3r and for me to run it I needed to set up a virtual Linux machine and compile everything over command line to unlock the non-plan our 3D printing settings for me the surprising part was based on the popularity of my video and all of the feedback at the time this was something the community was very interested in yet it's never really taken off shout out to Stefan from CNC kitchen for making a series of videos on non-plan r 3D printing but the catch is as with my video the process is not available without a certain level of tinkering you can't just download a normal slicer and use it there are still some other options around and some of them like this one you're seeing here look incredibly promising but if we click through to the shop we can see that it's mainly modified nozzles to give the required clearance and if we weigh far enough into the shop Pages we'll see that there is a software option but once we open that and read the description we can see that it's an add-on for Rhino modeling software so again not useful to the majority of people considering that me and many of you would like to do more non-plan out 3D printing the question is when will it be available in a regular slicer prer slicer team if you're watching this I'm hoping you will be the chosen ones given your track record of innovation and also that the version I tested was based on slick 3r just like your slicer if you also want nonplanar let the developers know in the comment section below recently I was wondering does filament flow differently in each hemisphere let me explain this image here depicts a hurricane and this image here depicts a cyclone maybe you think they're the same thing just with a different name but there is one important difference if you examine the Sr you'll notice that hurricanes Spin anticlockwise and Cyclones spin clockwise and that's related to what part of the globe they form thanks to the rotation of the earth and the Coriolis force a common idea that you'll hear is that toilets and sinks will drain in either a clockwise or anticlockwise Direction depending on whether they're located in the Northern or Southern Hemisphere unfortunately that seems to be proven as incorrect a myth that's been perpetuated for decades thanks to popular culture and probably social media too too recently I was purging some filament through a 3D printer hot end and noticed that it was coming out in a clockwise formation and that is exactly the same as the Cyclones found in the southern hemisphere where I live thinking this must be a coincidence I then extruded in fre a on a number of my other printers and guess what every single one without fail extruded in a clockwise spiral I don't want to get too excited but it's possible I've stumbled on one of the greatest scientific discoveries of our time coincidence almost definitely but I won't know for sure until you test this as well try it out and answer the comments what direction it goes and what hemisphere you're in this next question is more serious and I wish I didn't have to ask it and that is why is the maker Community becoming more toxic fdm 3D printing since its early R rap days has been about Community back then 3D printing wasn't convenient or easy so people work together collaborating to improve the results I started my 3D printing Journey in 2012 with a make aot replicator 1 it's a fossil by today's standards but I remember it being reliable and actually pretty good however that one was owned by my school and my first personal 3D printer was the solid oodle 2 its feature list was pretty sparse and I was part of a group that collaborated to bring advancements such as LCD displays this amazing Community was on solo Forum where everyone was respectful and enthusiastic about working together for the greater good fast forward to five or so years ago and companies like reality flooded the market with products like the Ender 3 which overall were fairly capable but still had enough shortcomings that the community could work together developing mods and upgrades fast forward again and more and more manufacturers have entered the 3D printing market and many of the new ones have not focused on a cheaper price but instead adding smart features and ensuring their printer just works with common problems eliminated people tend to become more negative obviously the problem's not in everyone so let me explain with this standard distribution graph the majority of people fall into the middle they're normal or average 3D printing enthusiasts they enjoy the Hobby and they're open to lots of different products and ideas then we have people with what I call a reasonable preference or bias this might be brand loyalty to one particular company they might recommend this brand to others but they don't try and force it down their throat the problem comes from the extreme minorities on either side those people who have fallen victim to tribalism if you don't agree with them then you must be the enemy and you must be attacked Let me Give an example on my channel I've built a couple of Premium corxy printers a rat RI Vore 3 and a second SK tank the majority of people enjoyed watching along as I built the printers but then there were these folks and I'm sure some of them were just asking an innocent question in good faith but they get lost amongst the chorus of build a voron build a voron build a voron aoron would be better this would be better on a voron have you heard of voron build a voron I'm sure you get the idea and I couldn't even fit all the of these on one screen you wouldn't think it would be possible but both of these printers I've built are actually fantastic they were fun to build I got to customize them how I liked and they're both very fast and still have very high quality prints I'm happy with my decision and I know that my patrons who chose to build borons are happy with theirs as well almost as if there's more than one good option available but you'd never know it based on these comments polluting my channel but unfortunately the hardcore people are sometimes the loudest despite being the minority currently however the toxicity has found a new home once again it's not your average 3D printing Enthusiast it's the people who are either obsessed with bamboo lab or prusia on my prusia XL video there were people there with an irrationally large ax to grind and when I tested the bamboo lab A1 there was plenty of irrational vitriol towards them too of course the truth is that each of these printers has strengths and weaknesses currently the multicolor prints from my EXL aren't quite on par with those from bamboo lab but the prints are relatively f fast and don't waste that much filament the same model in filament using a bamboo lab AMS is pretty close to Flawless but it takes around 6 or seven times longer and waste all of this filament but the people on the fringes of each of these groups won't accept that there's an engineering compromise made and each approach pays off in different ways but worse than that they'll cherry pick any argument that makes their side look better and if that fails they'll just simply make things up and honestly it just ruins it for the rest of us it's an underappreciated skill to accept and acknowledge differences in opinion without causing conflict and I hope this is something the community practices more moving forward I lighten the mood by asking why does my filament snap like this I think most people have noticed that as filament gets quite old it deteriorates in quality and can become quite brittle but my situation well it was different what you're seeing here is the reverse bden tube of my rat rig and this is the piece of filament that came out of it well eventually because it was really stuck it looks like it snapped once but if we we look closer we can see it's actually snapped in multiple places along the length of course every time it snaps that portion is a little bit wider and it likes to jam inside the tube so my question is what did I do to deserve this what's a 3D printing equivalent of smashing a mirror walking under a ladder or crossing a black cat if you've got the answer please save me in the comments what is the 3D Beni secret and I imagine for most people they don't even know that it has one if you do 3D printing it's probably impossible to not know what this is the humble threy Beni is immensely popular as a benchmarking tool the designers at creative tools included a range of geometry in the Beni that allows you to test for accuracy details and test the performance in other ways such as overhangs and part cooling it's actually quite a useful tool more than you might think which is why I previously made a video explaining how to use the Beni as a diagnostic tool but there is something mysterious missing from this list and I believe it was the real s Apprentice that revealed this shocking development when we were both guests in a live stream if you have two benches you can turn one upside down and they actually slot together try not to have your mind blown when you test this for yourself as soon as the proof became undeniable my mind was racing is this another print quality test are we testing clearances and tolerances no that can't be right or it will be mentioned on the website so that begs the question do the designers of the ready Beni even know that this is a thing what are the chances that dimensionally this is just a complete coincidence how did Sam Prentice know about this is he the Mastermind behind the whole thing is he trying to indoctrinate this poor person he's pretending to interview am I now in too deep is it still safe okay I'm probably overreacting but I would like to know whether this was an intentional design choice or just a happy accident again share your knowledge and get your theories into the comments one more and it's the most technical and serious of the lot our final question is what creates the surface artifact I'll demonstrate this with a very simple example here is a rectangular prism printed on the prusia XL and as you would hope it looks pretty much Flawless but look what happens to it when we print a single cylinder alongside can you see it here it is highlighted and it's clearly a flaw compared to the original it seems clear to me that the artifact on the tower is on the same plane as the top of the cylinder so even though these are two separate objects one of them can affect the other this artifact was brought to my attention by Patron Nova Plus plus and they pointed out it doesn't only happen when you have separate models it can occur when there's only one model in the print where features such as holes start and finish they even created a test model to determine how any particular combination of hardware and software suffers from the artifact I did print this and at first glance the artifact is not that obvious however when we change the lighting and turn the model sideways all of a sudden it seems really clear given though this small bridge is down here we clearly have an indentation where it starts and ends the same goes for the adjacent Bridge here and a small indentation for the top Bridge interestingly enough the cylinder doesn't seem to be affected nor does this prism on the other side so what is the culprit at the moment my current theory is flow rate in the earlier parts of the model the demands on the hot end are pretty uniform each shape has sparse infill and two perimeters but once we get to the top of the cylinder all of a sudden there's a lot more plastic going through the hot end due to the multiple layers of solid infill this increase flow might pull temperature out of the nozzle and for this example I think that fits because the filament looks more matte than shiny in that region which is normally associated with cooler temperatures and on other printers that might form under Extrusion which leads to the little indentations if you're confident you know the cause please share it down below because once it is known I think it can be mitigated in the slicer that brings us to the end with hopefully some food for thought thanks to my viewers and patrons for their ongoing support in 2023 I wish you a Happy New Year Year and hope that 2024 brings you happy 3D printing good day it's Michael again if you like the video then please click like if
