Achieve true 3D printing with non planar slicing

This is the most interesting thing I’ve done with my 3D printer in some time. Instead of printing in a series of 2D planes stacked up to form a 3D shape (2.5D), this non planar technique creates geometry with true 3D tool paths that can eliminate the steps often seen on shallow surfaces. Based on the amazing Masters Thesis of Daniel Ahlers and the University of Hamburg, this development can be tried yourself if you are willing to put in some time to setting it up.
In this video I’ll lead you through step by step on how to setup a virtual Linux machine on your PC, compile the custom version of Slic3r and then share with you my results. The future is bright and I thank people like Daniel Ahlers and Moritz Walter for leading the way.

[@TeachingTech]

Hi everyone, some updates: - A bunch of people pointed out that Windows 10 now has an embedded Linux environment. I installed this and went through the process again. I had a couple of errors and had to manually install missing cpan libraries via the command line. Slic3r did successfully compiled, but only runs via command line rather than with a graphical user interface as seen in this video. I'm sure there's a way to add even more modules to get the GUI working, but it's beyond my knowledge. - Some people also mentioned setting up a dual boot configuration. This is another great suggestion but I need to have my Windows PC on at all times to keep my video production going, so not suitable for me. - There have been some viewers pointing me towards 'air brush' nozzles. I've ordered a set, they look ideal for this technique.

It's possible to run a Remote X instance in Windows to render GUIs for Linux programs. I haven't used Xming in half a year, but it should allow you to run any of the Slic3r GUIs when the X server and Xming are configured correctly.

Most people write instructions without really making it something someone can follow from scratch, mainly because this can be extremely time consuming to do. And some people barely write instructions at all.

[@Technicallyaddicted]

When I bought it the ender3 pro was the best bang for buck in all of additive manufacturing. In 2021 a lot of people dismiss it as glitchy and poorly made. I have about $500 invested with all the mods over the years. Based on mm, speed of travel and number of hours printing my printer head has traveled over 1000 miles, and printed more than 40kg of plastic. The thing is a highly underestimated workhorse. Sla is nice and all, but with some sandpaper, a shadow detector, and bondo I’ve been getting functional mechanical parts and desktop accessories that rival the best you can get in FDM. My ender 3 outperforms a $1000 Prusia with ease. I’ve done all the repairs myself so I know this thing in and out. Still rocking original steppers, and power supply. After more than 10,000hrs!!!

@@toddkuznitz3629 there are much better kits nowadays and SLA has come miles. An elegoo Saturn will run you back $500 and is so detailed you never need to buy a model kit again. I think creality has some new offerings too all in the sub $500 category. However I don’t plan on upgrading until this hobby is pubic and not niche. My ender3 has been tricked out so far that it doesn’t make sense to upgrade. I have almost every performance mod you can get, but still run stock hotend, PSU, stepper, frames and belts. I’ve changed hotends once in 4 years. More important than quality of printer is quality of assembly. I get wicked prints not because of the mods I’ve done, but because every parallel bar sits at perfect level to the table and then to the floor, and every perpendicular bar sits at exactly 90• not 91, not 89. Threadlock where needed torqued to 20ft-lbs. every single screw, every single bearing every single roller triple checked. A smart person can have one assembled in less than an hour, but to do it properly should take you 4-5 if you know exactly what you’re doing.

You can modify the printer that you allready have ;)

[@xaytana]

@@GuyMassicotte Problem is, 5 axis is much more difficult than just adding a couple of axes to a normal printer. G-code becomes more complicated. You'd need a specific program for it, as 5 axis uses a different coordinate system. Slicers are only programmed to make layers, where a true 5 axis part would need shells. And the current non-planar solutions are only generating shells on the top surface, where a 5 axis part would need a shell that covers all surfaces; think of topology and transforming a cube into any other shape, 3 axis can only manipulate the top face, 5 axis can manipulate more than just that one face. There's reasons why 5 axis printing is mostly still in development, with the only working variants being highly experimental. Same reasons as why 5 axis machining is just recently starting to get into the hobby market. It's not as simple as you might think it is. But go ahead, modify a printer to have two more axes, without the rest that's needed for 5 axis, and tell us how that works out.

I mentioned this on the other video, but the next logical steps for non-planar are hot ends that have steeper angles, taller height to width ratio. Basically, with a steeper angled nozzle, it could fit into tighter curves. This also needs an entirely different cooling system, though, but that shouldn't be too difficult to develop. Non-planar also nicely extends into 5axis printing, which should be the next step of developments for the future of FDM.

[@KannaKamui]

With modern printers like bambu's using load cell setups, and third party nozzle adapter existing, mixed with a volcano nozzle for long length, this seems more viable than ever; minus the part cooling needing a bit of modding

As I was watching, I already solved (possibly) the BL Touch problem, with a simple rod and spring that could be swung into, and then out of position on a mount that would relocate it vertically. Think of a small C channel on a hinge that holds a precision rod and spring for retraction. Or use a servo to hinge it out out the way when done. We are a very smart community of talented people. Just a matter of time and will.

Next to design a extruder mount that allows for the BLTouch to be easily adjusted off the side during such a method of printing. I am in awe and inspired by the print results shown in the presentation. Yes, excellent stuff for sure.

[@CatCommando]

no need for mods, the volcano knockoffs already have a smaller heaterblock rotated 90 degrees with all the wires coming out of the top, this makes the longer v6 nozzle itself the only thing for many milimeters. I am making a 3d pen with one for these same reasons, it allows much more clearance around the nozzle which would work well here as well as a tilting pen. amazon has 15 dollar all metal throat v6 knockoff kits which include normal and volcano blocks and many nozzles for both.

It’s fast, high quality and simple to use. Many well known manufacturers are using it today.

[@rogerfroud300]

This technique could still be useful on conventional printers as long as you could map the 3D geometry of the areas that could potentially collide and detect whether that would actually happen or not. You could then use it for those cases where you have shallow slopes. Another thought would be to combine the two techniques so that you only allow a certain restricted amount of non-planar printing, before having to complete everything to that planar level and then resuming non-planar printing. It's not ideal, but better than conventional printing.

[@NicksStuff]

I was amazed at the first viral video and I'm so pleased one of the main channels has actually done it! The main issue I see from the video is the lack of part cooling, which can be solved easily, I reckon: add a pause just before the printing of the top layers and remove the fan shroud only then

[@MrVelociraptor75]

add a set of solenoids that automatically lift the fan assembly (and leveling sensor) out of the way ;) - I've seen it done for just the sensor, can't be that much harder to add that to the fan system. It would massively increase the weight of your print head though lol

[@tinayoga8844]

I had recently been thinking of this kind of technique. I had thought that this technique would be more easily implemented with a delta based 3D printer. So that the print head could be tilted.

Hey, that's a great idea!

[@lordgort1986]

you cant tilt the nozzle on a delta. the nozzle will always be parallel to the printbed

[@Celcius1]

it is very much doable, but is highly dependent on the Delta Design, my current delta prototype will actually do this, once i get the new board in, and some Titan Extruder spares. Cause the hot end hangs below the effector plate, with the magnetic arms on my printer giving a good range of movement the code can be adjusted to tilt the head. But it depends if slic3r can be adjusted to generate G-Code like this

[@1kreature]

@@lordgort1986 Wrong. With a parallel rod delta you can't but with a true delta you can. The HexaPod uses extending arms instead of delta towers but concept is the same. IN essence you need 2 motors on each of your 3 towers to give this ability. kzbin.info/www/bejne/fZC4npuLn7-bhNE

I always find it funny how the first step to installing a nix program is so often, "Build a dedicated computer to run the computer."

[@flippy9133]

Crazy that even 4 years later this is still not widely used today.

See my follow up video. Even more frustrating that a version exists in a modern codebase but it still hasn't been adopted.

You explained this VERY well. Congrats dude. I foresee a new era in 3D printers, AND an entrepreneur's opportunity galore

Well... Time to put heatsinks on my Z axis motors.

How do you not have more subscribers?!? Your videos are incredibly insightful and practical. Thank you for sharing your knowledge with people who aspire to improve their 3D printing.

[@jerbear7952]

There aren't that many people deep diving in to 3d printing. For those that do, we all watch him. Also, a lot of people don't subscribe. They just watch and move on.

[@jaycie5021]

I wonder how much this effects the strength of the part. Skilling it should make the part much less likly to suffer layer seperation durring stress.

[@haraldhimmel5687]

Right. Might also be interesting for carbon fiber composites which arent really doing anything in between layers.

[@Worrsaint]

@@haraldhimmel5687 if I recall it is called continuous strand composites (or something similiar). They generally wrap it around a foam core changing the wind angle as they go. It is how f35 nose cones are done. It is also how they do composite reinforced pressure vessels.

[@MushVPeets]

Yep! And if we went all the way and got print heads with tilt, you could make some ridiculously strong parts...

[@slayyou]

@@MushVPeets couldn't you tilt a Delta's head?

[@remotesailingpedroj]

That was exactly what I was thinking, extruding continuous strands of carbon fiber composites, can in theory, be achieved today with a delta printer. But slicing it looks like a nightmare.

[@RyanKirk99]

I am so excited for the future of 3D printing. I really hope this tech reaches mainstream in the next couple of years. Especially tilting nozzles. That sounds like the best way to keep cooling in place, and not have to reengineer nozzles and hotends. If some company could release an affordable (sub $5000) tilt nozzle printer and slicer they could corner the market. For a little while at least until it's reverse engineered.

[@theKashConnoisseur]

Finally, a reason for SCARA printers to exist!

[@scotthoffmaster4600]

Dude, Your one of the most intelligent 3d tech guys on youtube. . BUT that was next level stuff my brother! You still managed to pull it off in a stellar way! Cudos!

[@Arek_R.]

That's cool, but too much difficult work on software side. I think it could really take of if CURA would make experimantal mode with it. Then people would just need to remove the fan shroud, on stock Ender 3 that's actually easy,

[@Sven_Hein]

I get your point. It's not a very user friendly method yet.

[@T1g3rch3n]

Charlie Horvath the guys from Prusa already started with implementation if I'm understand the comments in the 'viral Video' right

[@SlavicusVile]

>an hour, maybe 2, maybe 3 of getting the software set up is too much work I don't know if 3d printing is a good hobby for you

[@Arek_R.]

@@SlavicusVile You don't understand, I don't need planar printing that much to invest hours into it

[@haraldhimmel5687]

Its not difficult at all. Optimizing the hotend seems more tricky, to get really decent clearance as well as part cooling.

[@redline5725]

MAN HOW AM I SUPPOSE TO UNDERSTAND ALL OF THESE MASSIVE INFORMATION THO? PLZ HELP THESE THINGS ARE SO COOL

[@freemansfreedom8595]

The true question, that no one asked or cares: How long till someone adapts slicer just for kicks and giggles, so it does a negative nonplanar route for proper CNC machines?

[@tektechnician]

Non planar operations are not desired for CNC as it changes the depth of cut and creates uneven loading on the machine bit which can impact surface quality and tool life. Imagine you're trying to cut a 45 degree slope into a block in a non planar route, not only will the round tool bit cut an ellipse valley, but the loading will increase drastically as you continue deeper into the slope.

[@new1ru]

There's nothing new for CNC mill stations this time.

[@freemansfreedom8595]

First is for fun. Not because it is the most desirable, but just because you want, and can. A lot of passes would go on empty air, sure, it may not be the best option either, but far from completely non desired. Foundry molded forms are an example of this, where you only need to reduce to size a small quantity of material. And 5 axis machines give you the freedom for it to be far less of an issue (not the scope of a project done for fun though).

[@tektechnician]

@@freemansfreedom8595 When you refer to "proper" CNC machines I am not sure whether you are referring to the likes of Hass VM-3 etc which are true 3D machines or a 2.5D router. Both are commonly referred to as a "CNC" machine. Assuming you are referring to manufacturing a set of sand casts drag and cope moulds, it still doesn't make any sense why forcing a tool bit to cut at an unoptimal angle is faster, it induces premature wear on the tip and is more likely to break the tip. Basically costs you more in time and tooling. If you have burnt a drill bit before that's pretty much what happens. Pretty much all professional CAM packages are designed to provide the quickest, optimal operations for tool life. Also with 5 axis machines, they're pretty unsuitable for commercial casting, if you can't cut the mould with a 3D machine, you can't release the sand regardless. 5 axis could work if you're sacrificing the "mould" (investment casting), but then there would be better options for manufacturing speed. Eg 3d printing :).

[@Litl_Skitl]

@@someguy4915 Nah he installed an emulator.

[@someguy4915]

@@Litl_Skitl No, an emulator emulates the hardware, a VM virtualizes the same or similar hardware. You'd use an emulator to run an ARM operating system on x86 etc. Using an emulator to run x86 Linux on an x86 pc would just slow everything to a crawl (and x86-x86 emulators thus do not exist anyway)...

[@nickcarter4006]

Just compiled this on my Raspberry Pi 4 and it appears to be working great, just exported my first gcode and I'm about to give it a shot!

[@nickcarter4006]

So I compiled the software and made code, but when I went thru the preview it looks like it’s not generating any non planar moves, even though it’s enabled in printer options and I set the settings to wiiiiide open (75*, 100mm). Can anyone assist with this?

[@nickcarter4006]

So in the end I realized the model I was using wasn't a good fit for non-planar printing. Eventually I'll try again with something more appropriate, but ironically "true 3D printing" isn't compatible for objects that are too 3D to be processed... seems to require a curved plane where as I was trying to put finish on the curved ends of a mask

[@stevesloan6775]

Wow that was a seriously interesting video. Bloody top work! 🇦🇺🤜🏼🤛🏼🍀🤓

[@Adam-qr4jj]

This is huge, there was a slicing software being developed to do exactly this but was never release. Im sure it wasnt gonna be cheap. Glad we can do this for free.99

[@christophalexander4542]

Does it show my impatience when one of my first thoughts (after "holy cow that looks good!") was that this means you can print with a HUGE layer height and literally cover it all up later? That should speed up prints massively.

I think you can do that already though, but yes. Even better finish.

[@Kycirion]

I want someone to figure out how to fixture something on the bed, edgefind, then print on the top surface, much like a CNC mill.

[@pugnate666]

This is amazing! Always wondered why no slicer does this - not necessarily 30° slopes, but 10-20° would already be super nice. Luckily the Thesis was made public, so the hardest part has already been done ...

[@seancarson551]

Has there been any progress on this? I would love to be able to just dump a model into Cura or S3D and watch it go.

[@tornberg]

While I did manage to reproduce your results for the part that you shared, I found that when I tried to apply the same slicing method to a Cherry-MX keycap, the slicing looked fantastic, but when the printer got hold of the G-Code, it almost ground to a halt in the corners. Having a look at the G-Code, it looks like the resolution is relatively ridiculous, at least compared to a keycap sliced the normal way. For a 3mm wide brim of a normal sized keycap, the slicer now produced over 500 rows of code, each containing XYZ-coordinates, compared to about 100 rows with only XY. The printers slow handling of the GCode lead to that the nozzle stayed so long in each corner of the cap that it was deformed and swollen by the heat and oozing filament. I tried using scripts to reduce the resolution for any layer/row of G-Code that had the same Z-value, making the insane resolution do it´s thing just where it really needed XYZ, but it did not really improve anything. Did any of you other guys find anywhere in the source to change the resolution somehow? I did not. I used OctoPrint, maybe it would be faster using SD-card?

[@marcosmoura911]

Do you have 8bit or 32bit controller?

[@bluedeath996]

With kinematic leveling on printers like the ratrig could you revisit this? Where the bed tilts to make sure there isn't any contact with other parts and keeps the hotend perpendicular to the printing direction. it would also be interesting to see if you could print otherwise impossible features by tilting the bed so they are vertical.

[@britewires4305]

That's why the ratrig is the right choice right now

[@w00tse]
